NOTE:
Install pin into the composite bearing dry. Lubrication is
not required with nickel plated pins and bearings.
12.
Inspect spacer for burrs and sharp edges. If necessary,
dress inside diameter surface with Scotch Brite or equiv-
alent.
13.
If applicable, inspect port block fittings and holding
valve. Replace as necessary.
14.
Inspect the oil ports for blockage or the presence of dirt
or other foreign material. Repair as necessary.
15.
If applicable, inspect piston rings for cracks or other
damage. Replace as necessary.
ASSEMBLY
NOTE:
Prior to cylinder assembly, ensure that the proper cylinder
seal kit is used. See your JLG Parts Manual.
NOTE:
Apply a light film of hydraulic oil to all components prior to
assembly.
1.
A special tool is used to install a new rod seal into the
applicable cylinder head gland groove.
WHEN INSTALLING NEW SEALS, ENSURE SEALS ARE INSTALLED PROPERLY.
IMPROPER SEAL INSTALLATION COULD RESULT IN CYLINDER LEAKAGE AND
IMPROPER CYLINDER OPERATION.
