Assembling lifting cylinder

Note:
The components marked in the figure form part of 
the reconditioning kit (13).

1.

Fit the sealing ring (9) in the new dirt scraper 
housing (11) and fit the "O"-ring (10) into the 
outer groove, see situation A.

2.

Fit the sealing ring (8) into the new brass 
upper bearing (7) and fit the "O"-ring (6) into 
the outer groove, see situation B.

3.

Slide the dirt scraper housing (11) over the 
piston rod.

4.

Slide the circlip (12) over the piston rod.

5.

Slide the new brass upper bearing (B) over 
the piston rod, as shown.

6.

Slide the stop ring (5) over the piston rod, 
ensuring that the tapered side fits into the 
upper bearing.

7.

Fit the circlip (4), possibly using an axle 
spring clip pliers (outer circlip pliers), into the 
piston rod groove.

8.

Slide the existing piston (3) over the piston 
rod until it touches the stop.

9.

Fit the circlip (1) onto the piston rod, using an 
axle spring clip pliers (outer circlip pliers).

10. Position the cylinder upright in a vice. Press 

the piston rod into the cylinder. Tap the brass 
upper bearing approx. 5 mm into the cylinder 
(past the circlip groove) with a punch.

11. Fit the circlip (12) into the cylinder. Pull the 

piston out fully to check whether the circlip is 
properly seated in the groove. This also puts 
the upper bearing in its final position.

12. Turn the cylinder upside down and press the 

piston into the cylinder using the cab tilting 
pump. Add another twenty pump strokes 
when the piston has been fully pressed into 
the cylinder to bleed the cylinder.

13. Press the piston out of the cylinder and 

pressurise the cylinder. Inspect the latter for 
leakage.

14. Tap the dirt scraper housing (A) evenly into 

the cylinder using a plastic or copper 
hammer.

15. Fit the dust cover.

16. Attach the lifting cylinder underneath the cab 

and check its operation.

6. DRAINING AND FILLING

6.1 FILLING AND BLEEDING, TILTING MECHANISM

Note:
-

Check whether the lifting components have 
been fitted correctly and whether the 
connected piping is secure enough.

-

Do not add oil to the pump reservoir when 
the cab is tilted. Add oil to the reservoir only 
when the cab has been completely tilted 
back.

-

Check the cab tilting pump, the lifting 
cylinder, pipes and connections for any 
leakage.

Filling tilting mechanism
1.

Clean the area surrounding the filler plug. 
Remove the filler plug.

2.

Put the pump plunger in bottom position by 
moving the pump actuating rod fully down.

3.

Top up the reservoir with the specified oil, 
see specification manual "Fluids and 
lubricants", to the top of the pump plunger.

Note:
The cab must be tilted completely back into 
place.

Bleeding tilting mechanism
1.

Place a tray beneath the pump to collect the 
oil.

2.

Start with approx. 30 full pump strokes while 
leaving the cab tilting pump in the reverse 
tilting position. If necessary, top up the 
reservoir with oil.

3.

Tilt the cab fully forward (cab tilting pump in 
the tilting position). Continue pumping and 
keep the system pressurised. Check all the 
connections for leaks.

4.

Tilt the cab back. If necessary, top up the 
reservoir with oil.

Note:
If the lifting cylinder has been overhauled or 
renewed, the cab must be tilted twice to 
obtain full bleeding.

5.

Fit the filler plug.

Refilling tilting mechanism
1.

Carefully loosen the filler plug 3 to 4 turns 
and wait until the overpressure, if any, has 
left the reservoir.

2.

Remove the filler plug.

3.

Turn the cab tilting pump into the tilting 
position and start pumping until this is clearly 
getting heavier.

4.

Put the pump plunger in bottom position by 
moving the pump actuating rod fully down.

5.

Top up the reservoir with the specified oil, 
see specification manual "Fluids and 
lubricants", to the top of the pump plunger.

6.

Fit the filler plug and set the cab tilting pump 
into the reverse tilting position.
