the gland nut using a spanner wrench. Tighten the gland
nut as much as you can using the spanner wrench. Make
sure the threaded area of the gland nut and cylinder barrel
are free of oil before applying the loctite bonding
adhesive.

cylinder passes the piston seal test then, assemble the
cylinder to the loader.

Install the piston assembly to the cylinder rod. Some
rear piston assemblies are threaded onto the cylinder rod.
Use a spanner wrench to install the rear piston part to the
cylinder rod. Torque the lock nut to the rod at 250-275
ft lbs (339-373 N.m.). (fig. C3740)
