HYDRAULIC SYSTEM RT9130E SERVICE MANUAL
4. Install the replacement seal and wear ring on the outside
of the piston.
5. Slide the head onto the rod.
6. Lubricate freely all parts with clean hydraulic oil.
7. Remove the cover from the barrel. Insert the rod and
attached parts into the barrel with a slight twisting
motion.
8. Clean all oil from the threads of the head. Coat the
threads with an anti-seize compound (ex: Never-Seez
paste lubricant or similar lubricant). Screw the head into
place on the barrel tightly so it holds the head’s larger
OD end flush with the end of the barrel.
9. Pressurize and cycle the cylinder with hydraulic oil
pressure. Test the cylinder at 25855.3 kPa/25.8 bar
(3750 psi). Check for proper operation and any leakage.
Make repairs as needed.
CAUTION
Exercise extreme care when handling the rod. Damage to
the rod surface may cause unnecessary maintenance
and expense. Also, take care to avoid damaging grooved
or gland surfaces or rings or seals during rod insertion.
CAUTION
Do not use air pressure to cycle or pressurize the cylinder.
