FLEXIBLE COUPLING INSPECT/ALIGN/IREPAIR/REPLACE (CONT).
Re-align engine assembly as follows:
Loosen engine hold down bolts and gear support L-bracket bolts to skid.
Align engine by reducing misalignment values in the following order.
Lh, A, Lv, Xh, Xr
This order insures that the simplest and most sensitive parameters are adjusted first. Adjustment of all
values may not be necessary.
To reduce Lh, use lateral jacking screws (equally from one side or the other) to push engine sideways.
To reduce A, use jacking screws to move engine toward or away from pump.
To reduce Lv, add or remove an equal thickness of shims to/from all four (front and rear) engine pads.
Check the misalignment values by repeating step (b).
Torque engine mounting bolts to 123 ft-lbs (167 N.m).
Torque speed increaser support bolts to 50 ft-lbs (68 N.m).
Install coupling assembly.
