1.2 TIE BOLT TORQUE
The tie bolts on the pump are tightened before leaving the factory. However, relaxation
may occur due to handling, material creep, or other unforeseen events. Trebor
recommends that all eight tie bolts be re-tightened upon pump install. The following
procedure should be used:
1. Remove black tie bolt caps (Item 17 in Figure 4-1) from both sides of all 8 tie
bolts
2. Apply 80 in-lbs. (9.0 N-m) of torque to each slave side bolt while holding the
master side bolt stationary. A star-pattern is advised.
a. The master side is the left side of the pump if you are looking at the fluid
ports.
3. Replace the tie bolt caps.
