13. Check the alignment of the sheave (1) with the engine sheave (within 0.020”). Refer to Fig. 4.

NOTE: DO NOT attempt to move new pump sheave

(1) while compression spring is tightened to 1.5”.

Loosen compression spring before aligning sheave.

14. If the sheave (1) needs to be moved, loosen the tension on the yellow compression spring, move the sheave, and retighten the yellow compression spring to 1.5”.

15. Recheck the alignment of the sheave (1) with the engine sheave. This may need to be repeated several times until the sheave is aligned with the engine sheave (within 0.020”). Refer to Fig. 4.

16. Apply a small amount of Loctite 242 to the threads of the two set screw holes in the sheave (1). Refer to Fig. 4.

17. Hand tighten the two set screws (2) into the sheave (1) . Refer to Fig. 4.

18. Reinstall the engine fan. Refer to Fig. 2.
