HYDRAULIC CYLINDER REPAIR (CAB LIFT AND SIDESHIFT) - CONTINUED
If any of these parts are pitted, scored, gouged, or rusted, cylinder is beyond repair and should be replaced.
Inspect rod (5), piston (6), gland nut (4), and housing (1) for pitting, scoring, gouges, or signs of rust.
Install new seals (2) on piston (6) and gland nut (4).
There may be seals left over.
Inner seal can be shaped as shown below to install.
After installation, apply light coat of lubricating oil and run finger around interior of seal to position it.
Coat piston and gland nut seals (2) with lubricating oil.
Slide gland nut (4) onto rod (5).
Be careful not to damage seals when installing piston past the threads into housing.
Start piston (6) into housing (1) far enough to allow gland nut (4) to be started onto threads, which will align rod (5) to
housing during assembly.
Continue to push rod (5) into housing (1), leaving about 3 in. (7.6 cm) of rod exposed.
Assemble locknut (3) and clevis (not shown) on rod (5) end, and tighten locknut.
