REMOVAL
WARNING
Do not allow hydraulic fluid or cleaning solvent to come in contact with unprotected
skin or eyes. Prolonged skin contact can cause illness or injury. Eye contact can cause
serious injury. Always wear chemical protective gloves and goggles when handling
used hydraulic fluid and cleaning solvent. Failure to comply can result in illness, seri-
ous injury, or death.
Hydraulic hoses and lines may be under pressure. Relieve pressure by operating the
appropriate control valve if possible. Loosen fittings on hose lines slowly. Allow oil to
run around threads of fitting, releasing pressure before disconnecting fitting. Releasing
pressurized oil suddenly may cause serious injury or death.
1.
Don chemical protective gloves and goggles and position a suitable drain pan beneath the work area.
2.
Loosen, but do not remove, the hydraulic hoses (1 and 2) to allow any residual pressure and fluid to drain from the
system.
3.
Label and disconnect the hydraulic hoses (1 and 2). Cap the hose ends to prevent contamination of the system.
4.
Remove the circlip (3) from the clevis pin (4) on the rod end of the cylinder (5). Remove the clevis pin and spacer (6).
5.
Remove the circlip (7) from the clevis pin (8) on the piston end of the cylinder (5).
