Repair Instructions

Always consider safety precautions before beginning a service procedure. Protect your-

self and others from injury. Take the following general precautions whenever servicing a

hydraulic system.

Unintended machine movement

WWarning

Unintended movement of the machine or mechanism may cause injury to the technican

or bystanders. To prevent uintended movement, secure the machine or disable / dis-

connect the mechanism while servicing.

Flammable cleaning solvents

WWarning

Some cleaning solvents are flammable. To eliminate the risk of fire, do not use cleaning

solvents in an area where a source of ignition may be present.

Fluid under pressure

WWarning

Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin

causing serious injury and/or infection. This fluid may also be hot enough to cause burns.

Use caution when dealing with hydraulic fluid under pressure. Relieve pressure in the

system before removing hoses, fittings, gauges, or components. Never use your hand

or any other body part to check for leaks in a pressurized line. Seek medical attention

immediately if you are cut by hydraulic fluid.

Personal safety

WWarning

Protect yourself from injury. Use proper safety equipment, including safety glasses, at all

times.

Assembly

Housing Lead the pre-assembled swash plate

(D10) into the casing with the bearings

in the seats (D40).(Photo F000920)

Make sure the correct seat of the bearing,

and bearing's outer ring, and then use a

press to press in until stop.

(Photo F000921)

Screw in lightly the servo sleeve (F50)

until the stop of the swash plate.

The swash plate must remain free from

backlash. Using a measuring device

(depth gauge), set swash plate at zero

position by screwing in or out the servo

cylinder. The maximum differencebetween the depths between the two

points is 0.025 mm max.

(Photo F000922)

Assemble then the sealing ring (F60), the

spacer ring (F70) and the slot nut (F80).

Turn and lock the servo cylinder and

tighten the slot nut with a torque of

80 ± 10 Nm. Assemble plug with (F90)

the O-ring.

(Photo F000923)

Turn the pump housing so the flange

faces up. Place the pre-assembled shaft

with the bearing (B50) at the stop of the

pump casing.

Press the male tapered roller bearing

(B50) into the hole of the pump housing.

Assemble the retainer ring (B60).

Warning

The axial clearance of the

shaft must be checked. The

shaft axial clearance must

be between 0.01 and

+0.06 mm. If the values are

not reached, the

suitable distance plates

G25 must be assembledin the end casing. Pull the

shaft to measure the axial

clearance and measure

the clearance with a dial

gauge.

It must be disassembled to

replace the distance plates

G25 in the endcap.

of the pump housing with help of an

mounting device. Assemble the retainingring (B110) and check for the correct

position in the slot.

Warning

Check the static torque.

The torque to turn the

shaft should be

min.16. 0 - max. 23.5 Nm

(Size 070; 089)

Values outside of this

region are reason forcomplaint.

Test the tightness of the

pump with air pressure

in accordance with test

regulation.

Leakage of air from the
