NOTE
Relief valve (U) used in next step was
removed from track adjusting link
yoke at disassembly.
11. Install new packing (V) on relief valve assembly
(U). Coat threads of valve assembly (U) with
grease (Item 14, Appendix B).
12. Using 15/16 inch socket and torque wrench,
install valve assembly (U) into manifold block
hole (W) and tighten to 40-60 lb-ft (54-81 Nm).

WARNING
and tighten pipe plug (Z).
Wear goggles and cover relief valve
with a rag to prevent grease from
getting in eyes. Relief valve opens at
2150-2250 psi and blows a fine spray
of grease.
14. Watch gage (AA) and pump grease into manifold
grease fitting (P) until relief valve (U) opens
between 2150 and 2250 psi. If valve (U) opens
between 2150 and 2250 psi, turn needle valve
handle (M) counterclockwise to release
pressure. Remove valve (U) and packing (V),
throw packing (V) away, and go to step 15. If
relief valve (U) does not open between 2150 and
2250 psi, turn needle valve handle (M)
counterclockwise to relieve pressure. Remove
valve (U) and packing (V) and throw away valve
(U) and packing (V). Install new valve (U) and
new packing (V) (steps 11 and 12) and repeat
this step.
