Inspecting Pulleys
Check every time you inspect or change the belts. Replace if these conditions exist:
• Excessive wear in grooves, excessive pulley-to-shaft clearance, or excessive bearing play,
cracks, and so on.
Adjusting Belt
To adjust the belt, proceed as follows:
1 Loosen the two shoulder bolts at the bottom of the motor deck plate.
2 Loosen the two screws that attach the top of the deck plate with the upward flange on the
pump mounting plate.
3 Lift the motor to loosen the belt.
4 To tighten the belt, insert a large screwdriver or crawbar between the motor and pump
mounting plate, and push down in front, forcing the motor downward.
5 The Expansion Union will permit upward or downward adjustment with the conduit attached.
6 After you have achieved the proper belt tension, tighten the two upper screws, and then the
bottom shoulder bolts.
