INTRODUCTION 

GENERAL INFORMATION 

Carefully read the use and maintenance manual before start-up the motor. The 

use and maintenance manual must be placed near to motor installation location 

in order to guarantee operators easy access to the instruction manual. For further 

information please contact Italgroup. 

MOTOR DESCRIPTION 

R8D series motors are radial piston hydraulic motors (generally indicated as LSHT motors, 

low speed high torque motors) with a rotating shaft (1) and a stationary housing (2). The pistons 

(4) are located radially and the working fluid provide the mechanical force that push 

the pistons against the eccentric shaft, providing the shaft ouput torque. The inlet and outlet 

flow to and from the pistons is regulated by a distributor (5), that provides the oil distribution 

correct timing. The pistons transfer the forces to the eccentric shaft through a connecting rod 

(3). Acting in the adequate way (increasing or reducing the oil flow coming from the pump) 

the motor rotational speed can be increased or reduced. The motor design guarantee extremely 

high starting torque and high mechanical working efficiency. Respecting the limitation 

of working parameters (indicated into the technical datasheets) and all recommendations (including 

fluid recommendations), high motor lifetimes are obtained and very low maintenance 

requirements are needed.

HYDRAULIC FLUID RECOMMENDATIONS 

Fluid selection 

Optimal viscosity selection 

In general, we recommend the use of hydraulic oils with minimum viscosity 

index of 95, with anti-wear additives (ISO HM and HV). Once normal working 

temperature is reached, the drain oil viscosity must be at least 35-40 cSt, 

preferably in the range from 40 to 60 cSt. 

HE oils (ecological fluids) are allowed, but must be used with particular attention, 

because them can influence the motor seals compatibility, and can 

reduce motor performances and life. Please contact us in case of HE oils 

usage. 

Referring the first approximated selection to the room temperature, we advice 

the following: 

Room temperature 

-20°C/0°C BP ENERGOL HLP – HM 22 

-15°C/+5°C BP ENERGOL HLP – HM 32 

-8°C/+15°C BP ENERGOL HLP – HM 46 

0°C/+22°C BP ENERGOL HLP – HM 68 

+8°C/+30°C BP ENERGOL HLP – HM 100 

Oil 

-20°C/+5°C BP BARTRAN HV 32 

-15°C/+22°C BP BARTRAN HV 46 

0°C/+30°C BP BARTRAN HV 68 

ATF (automatic transmission fluid) oils, SAE 10-20-30 W oils, multigrade 

motor oils (SAE 15 W 40, 10 W 40), universal oils, can also be used. 

Always fill the motor (please refer to the “DRAIN RECOMMENDATIONS” 

section) with the selected hydraulic fluid before motor start-up. During 

cold start-up avoid high-speed operation until the system reach 

the working temperature, in order to provide an adequate lubrication. 

Every 5-8 °C of increase respect to the optimal working temperature 

for the selected oil, the hydraulic fluid life decrease of about 

40-50% (refer to “OXIDATION” section). Consequently, the motor 

lifetime will be affected by the working temperature increase 

respect to the optimal working temperature of the selected oil. 

The maximum continuous working temperature is 70 °C, the temperature 

must be measured from motor drain line. If the motor doesn’t have 

a drain line, the temperature must be evaluated at the return line port.

Filtration 

Hydraulic systems oil must always be filtered. 

The choice of filtration grade derives from needs of service life and money 

spent. In order to obtain stated service life it is important to follow our recommendations 

concerning filtration grade. 

When choosing the filter it is important to consider the amount of dirt particles 

that filter can absorb and still operate satisfactorily. For that reason we recommend 

filters showing when you need to substitute filtering cartridge. 

· 25 μm filtration required in most applications 

· 10 μm filtration in closed circuit applications 

Oxidation 

Hydraulic oil oxidizes with time of use and temperature. Oxidation causes 

changes in colour and smell, acidity increase or sludge formation in the tank. 

Oxidation rate increases rapidly at surface temperatures above 60°C, in these 

situations oil should be checked more often. 

The oxidation process increases the acidity of the fluid; the acidity is stated in 

terms of the “neutralization number”. Oxidation is usually slow at the beginning 

and then it increases rapidly. 

A sharp increase (by a factor of 2 to 3) in neutralization number between 

inspections shows that oil has oxidized too much and should be replaced 

immediately. 

Water content 

Oil contamination by water can be detected by sampling from the bottom of 

the tank. Most hydraulic oils repel the water, which then collects at the bottom 

of the tank. This water must be drained off at regular intervals. Certain types 

of transmission oils and engine oils emulsify the water; this can be detected 

by coatings on filter cartridges or a change in the colour of the oil. In such 

cases, obtain your oil supplier advice. 

Degree of contamination 

Heavy contamination of the oil causes wear rising in hydraulic system components. 

Contamination causes must be immediately investigated and remedied. 

Analysis 

It is recommended oil being analyzed every 6 months. The analysis should 

cover viscosity, oxidation, water content, additives and contamination. Most 

oil suppliers are equipped to analyze oil state and to recommend appropriate 

action. Oil must be immediately replaced if the analysis shows that it is exhausted.

Always fill the motor with hydraulic fluid before start-up. Arrange piping in a way that the motor cannot 

drain off and cannot generates air bubbles into the motor case. Under certain conditions may be is necessary 

to arrange a check valve in order to help avoiding the motor drain off. Always check carefully that the 

leakage line pressure doesn’t overcome 10 bar pressure: therefore leakage lines must be shorter as possible 

and with a minimum flow resistance.

MOTOR INSTALLATION AND STARTUP 

Motor installation and 

start-up 

The motor, after testing, it’s packed in different ways that depends by customer 

and/or logistic requirements. The motor must be carefully moved 

from his box or pallet, with the assistance of correctly sized movimentation 

tools, like eyebolts (all the motors has a thread hole in the shaft end, 

please refer to the R8D general catalogue, shafts section) or lifting slings. 

When the motor is moved from one place to another always be very careful 

and act in a way that the motor is stable and under control during 

movimentation (refer to handling and storage section for more details). 

Before mount the motor, check carefully the absence of damage happened 

for example during transportation and/or storing. 

For mounting dimensions please refer to the R8D installation drawings. The 

motor must be installed using the correct screws size (we recommends the 

use of 10.9 and 12.9 class resistance fixing screws) and must be placed on 

a structure that is capable to correctly support the motor during functioning: 

for this reason the structure must not only be able to support the motor 

weight but must also assure the absence of vibration during operation and 

must win the reaction forces that are generated by the working torque. Regarding 

the motor fitting design, the concentricity between the centering 

diameter (spigot) and shaft (both splined or parallel) must be assured with a 

strict tolerance (please refer to the following general indication). If the concentricity 

between the shaft and the centering diameter and/or fixing holes 

is not respected, in the worst case the motor can have an unusual failure or 

can work only with low performances. Splined adaptors (splined billets) are 

available upon request.

Hoses and piping must be clean and free from contamination. Use proper 

hoses for oil connection, both for inlet and outlet main ports, and for drain line. 

Refer to hoses and fitting constructors in order to correctly size and select hoses 

and fittings. In order to keep control on the oil compressibility keep hoses 

to the minimum recommended size and select pipelines most rigid as possible. 

The motor can be mounted in any position (refer also to drain recommendations 

section). In run-away conditions you must use counterbalance valves. 

When the motor is installed vertically with shaft pointing upwards, consult our 

technical department. If the motor is connected to high inertial loads, the hydraulic 

system must be designed to prevent peaks of pressure and cavitation. 

Consider the use of relief valves, possibly directly mounted on motor distributor 

in case the application can generates pressure peaks at the motor ports: the 

relief valve should be able to discharge all the flow (or at least a good part of 

it) with a limited pressure increase. Italgroup can provide differents valve types 

that can be placed directly on the motor distributor (please refer to Italgroup 

valves technical catalogue). 

Motor case and pistons must be completely filled with oil before starting. 

Do not load motor to maximum working pressure instantly. During cold start-up 

avoid high-speed operation until the system reach the working temperature. 

Connect the case drain directly to tank, and avoid excessive drain line pressure 

losses (the case drain pressure must not exceed 10 bar continuous pressure for 

R8D serie standard motors). The case drain port on the motor must be located 

on the highest point of the installation to ensure that the motor will always be 

full of oil. (See drain recommendations page for more details) 

Maximum oil temperature must not exceed 70°C. Heath exchangers must be 

used with higher temperatures. The operating fluid viscosity must always be 

higher than a certain minimum value (see “fluid recommendation” section) in 

order to guarantee an optimal motor internal lubrication. When the working 

conditions cause the motor case overheating above a critical value, the motor 

flushing is required. Flushing consists in the introduction of fresh oil (taken from 

the hydraulic circuit) into the motor case. Oil must be taken from the return line 

to avoid internal motor damage (the continuous motor case pressure must be 

maximum 6 bar). Flushing is an important operation that can be very effective 

to improve motor lifetime with heavy duty working conditions and improve the 

motor mechanical efficiency. 

The motor flushing, if the motor works in one direction only, can be easily 

performed connecting the motor return line to the lowest motor drain port. The 

highest motor drain port must be connected to the tank. For D75 and D90 flow 

distributors, the side 1/4” metallic plugs can be used for flushing circuit installation: 

infact the plug (corresponding to the return line port) can be removed 

and the connection between motor low pressure port and motor case can be 

correctly realized. 



17


MOTOR INSTALLATION AND STARTUP 

If the motor axis is not horizontal and/or the motor works in bidirectional 

operation, please contact Italgroup technical department, that can assist 

you to advice how to perform the desired operation in the best way. Just 

for your reference, Italgroup can provide you flushing valves in order to 

perform an effective flushing circuit. 

Minimum speed is very low and can reach values near to 0.5-1 rpm (depending 

on motor displacement). In case of low speed vibration a reasonable 

back pressure can eliminate or minimize the vibration and noise level (a 

general guideline value can be defined by 5-8 bar back pressure). For 

more information please contact our technical department. 

Back pressure limit for R8D series motors is 70-80 bar (back pressure occurs 

for example when hydraulic motors are installed in series circuit). High 

back pressure values are often responsible of motor overheating, so if drain 

temperature reach values that bring the oil viscosity under the recommended 

limit (refer to fluid recommendations section), perform appropriate motor 

flushing and/or reduce the back pressure. 

During start-up and in the period immediately after it, any hydraulic installation 

must be regurarly and carefully checked at frequent intervals. The 

working pressure must be checked in order to understand that it agrees 

with the design values. The drain line pressure for standard motors must 

not overcome 10 bar continuous. If leakage occurs, check the reason, 

correct it and carry out new measurements. Check all lines, connections, 

screws, etc, and tighten if necessary. Replace contaminated fluid immediately. 

The motor installation and start-up must be performed by instructed and 

experienced personnel only. 

Please contact us freely to obtain further information. 

18 


MOTOR HANDLING AND STORAGE 

Motor handling 

The motor must be correctly packed during transport and correctly stored into 

the warehouse in order to avoid eventual damages that can make the motor 

functioning not adequate. 

During handling operations, make sure that the motor shaft and tachometer 

shaft (if present) don’t receive any hit, in order to avoid motor damage. 

During all operations of lifting and handling, never movimentate motors by 

hand but use adequate tools. In order to avoid that motor can falls, creating 

danger for authorized working persons in the nearings, use one of following 

methods: 

- use lifting slings of adequate capacity; 

- use adequate eyebolt using the thread hole in the shaft end. 

Refer to the following pictures. 



19


MOTOR HANDLING AND STORAGE 

Storage 

Storing must be carefully made using adequate storing tools (for example 

boxes, pallets, etc...) that can guarantee that the motor is stable and cannot 

move without control, in order to avoid damage problems. Make sure that 

the weight of the motor doesn’t be substained by the motor shaft or by the 

tachometer shaft (if present). 

R8D series motors are supplied together with plastic plugs, that keep the 

hydraulic oil (that was used during final test in Italgroup testing workbench) 

inside the motor. A thin oil film is present on the internal motor parts, whereas 

the external parts are covered with antirust oil that prevents damage from 

oxidation and corrosion. 

Therefore the motors can be safely stored into the customer warehouse 

without performance losses for long periods (up to 4-6 months). 

The storing location must has some important characteristics: 

- room temperature comprised between -15°C and +55°C without fast and/or 

excessives temperature excursions; 

- low relative humidity; 

- absence of aggressive and corrosive medias in the motor nearings. 

In particular, if motor should be motionless for more than 4-6 months, it must 

be protected against internal rust. Proceed as follows: 

- fill the motor case with hydraulic oil. After that the motor case is full of oil, 

close it with a screw plug; 

- fill the motor also from inlet or outlet port. Turn the shaft by hand (the shaft 

must make about one revolution) and finally close the inlet and outlet ports. 

Please note that the plastic plugs are necessary not only to keep the hydraulic 

oil inside the motor, but even to avoid that dirt and other fluids (like water 

for example) can enter into the motor and create damage during storing or 

during motor start-up. Therefore make sure all drain ports, supply ports and 

discharge ports are closed during motor handling and storing. If plugs are 

missing, use plastic plugs or adequate systems in order to guarantee that 

the motor is well protected by dirt and other fluids.

MAINTENANCE OPERATIONS 

Maintenance operations 

All the assembly and maintenance works must be performed when the motor 

is stopped and not connected to any power source, in order to avoid an accidental 

start-up. In addition the pressure inside the motor must be set to zero 

(the motor must be depressurized) before to perform maintenance operations. 

The motor maintenance must be performed by instructed and experienced 

personnel only, following carefully Italgroup advices and procedures. 

R8D series motors are internally lubricated by the operating fluid, if the motors 

are used according to the technical data reported into the R8D catalogue, they 

need very limited maintenance operations. In order to achieve good performances, 

long bearings lifetime and safe working, the working fluid must be 

carefully selected in function of the operating parameters (a fundamental parameter 

is the ambient temperature range). In case of fire resistence fluid usage 

, some limitation on pressure and speed can be required. Refer to hydraulic 

fluid recommendations section for more information. If required please contact 

Italgroup technical department for further information.

INSTRUCTIONS AND ADVICES 

Bearings 

The bearing life depends by different factors, like bearing type, motor 

speed, working pressure, external loads, duty cycle, fluid viscosity, oil 

cleanliness, type and temperature. 

Lifetime is measured by L 10 

which is called “theoretic lifetime”. It represents 

the number of cycles that 90% of identical bearings can effort at 

the same load without showing wear and tear. 

Please refer to bearing lifetime diagrams reported in the following pages 

to obtain the theoretical bearing lifetime. The lifetimes diagrams shown 

the L 50 

, median or average lifetime, that can be considered as 5 times 

L 10 

. 

Please note that the theoretical lifetime can be different from the real 

lifetime, especially in case of heavy duty applications with continuous 

work cycle. 

Please contact Italgroup S.r.l. for more information. 

Motor creep speed 

The hydraulic motor is able to hold the load acting as a brake (if proper 

valves or circuit are considered and installed), but a certain creep speed 

is always present: this is typical of all brands hydraulic motors. 

The motor creep speed depends by many factors, like operating conditions 

(motor displacement and type, pressure load on the shaft, oil viscosity, 

type and temperature) 

If creep speed is higher than desired value a negative brake can be 

considered: Italgroup can supply negative brakes that can be fitted to 

the hydraulic motor. 

Please contact Italgroup S.r.l. for more information.

SPECIAL FEATURES 

Special features 

Marine painting 

If needed, special painting or primers are available in order to guarantee 

optimal protection against normal corrosion and marine environment corrosion. 

The ordering code is MP. Please contact Italgroup S.r.l. for more 

information. 

Speedy-sleeve 

A special inox sleeve is available upon request. In case the motor is used 

in aggressive medias or environments, this can be very useful in order 

to protect the motor shaft surface located in proximity of the motor shaft 

seal. This improves the shaft and seal endurance respect to wear and 

corrosion. The ordering code is SPSL. Please contact Italgroup S.r.l. for 

more information. 

High pressure shaft seal 

Standard R8D motors are supplied with high pressure shaft seals, the 

continuous drain pressure must be maximum 6 bar, whereas the peak 

drain pressure must be maximum 10 bar. In case the drain line can or 

must has a higher pressure, special shaft seals are available upon request. 

The ordering code is HPS. The drain pressure with HPS shaft seal 

can reach 20-25 bar continuous pressure and 30 bar peak pressure. The 

HPS shaft seal is bi-directional also, so it can be used for example in underwater 

applications. Please contact Italgroup S.r.l. for more information. 

Counterclockwise rotation 

Standard R8D motors are supplied with clockwise distributor timing. Please 

refer to the installation drawings of each section for more information. 

With ordering code CCW the motor is supplied with counterclockwise 

rotation timing. Contact Italgroup for more information.
