2. Move the piston to the middle position. Unscrew the gland (pos. 10) from
the cylinder casing (pos. 5). A special tool is needed to remove the gland.
If the gland is stuck, it may help to warm up the very front of the socket.
When the gland has been unscrewed, pull the piston out towards the gland.
Pull the piston rod (pos. 7) out of the cylinder casing (pos. 5).
3. Remove the locking nut (pos. 1) which holds the sleeve (pos. 2).
4. Pull the sleeve (pos. 2) off the piston rod (pos. 7).
5. Pull the gland (pos. 10) off the piston rod (pos. 7).
6. Remove the seals from the gland and the sleeve (pos. 3+4+6+8+9+11+12).
7. Clean all parts thoroughly. Check for filings, shavings, burrs and make
sure that there is no rust around the scraper ring (pos. 12) in the gland. If
this is the case, it must be removed.
Assembly
1.
Assemble the new seals into the gland and the sleeve (pos.
3+4+6+8+9+11+12).
2. Lubricate the screw threads on the gland (pos. 10) and the cylinder casing
(pos. 5).
3. Place the gland (pos. 10) onto the piston rod (pos. 7).
4. Mount the sleeve (pos. 2) and screw on the self-locking nut with Loctite .
Make sure that the screw threads are completely clean and free from oil or
other impurities before using Loctite.
Do not refill the oil for the first 12
hours after the application of Loctite.
5. Lubricate the outermost seal on the sleeve which has contact with the cyl-
inder casing and the inside of the cylinder casing with oil, then guide the
piston into the middle position.
6. Fit the gland onto the cylinder casing and tighten.
7. Mount the cylinder.
8. Attach the hoses. Make sure that the hoses are not caught or squeezed in
any way and that the connections are airtight.
Changing Packer Roller Fold Cylinders
The MaxiDisc must first be unfolded and lowered so that the discs are resting
securely on the ground. Relieve the pressure in the wheel cylinder so that the
wheels are resting on the ground.
4.
Dismount the hoses. (To avoid ground pollution, collect the oil in a tray
placed underneath the working area while carrying out repairs on the im-
plement.)
5. Remove the split cotter pin and the pin. The cylinder is now free.
1. Mount the cylinder in reverse order. Remember to make sure that the pin
is engaged in the stop and that the pins are secured with split cotter pins.
After installing the new cylinder, always bleed air out of the system and check
for leaks. Never allow bystanders within the operating radius of the MaxiDisc.
