Jabsco 18753-0006 Pulley, 6-1/2 in A-Section
The Jabsco 18753-0006 is a genuine Jabsco 6-1/2 in drive pulley for an A-section V-belt, used on belt driven bronze engine cooling pumps. It is listed for the pulley driven versions of the Jabsco 18830, 18840, 18930 and 18940 engine cooling pumps.
Check the pulley for worn or damaged grooves whenever the belt is changed, because a worn groove lets the belt slip and wear quickly. Keep the pulley in line with the engine drive pulley and set belt tension to the engine maker recommendation, since an overtightened belt shortens pump bearing life.

Frequently Asked Questions
Q: Does alignment matter?
Yes. A misaligned pulley wears belts and bearings quickly.
Q: Can I change pulley size?
Changing size changes pump speed and flow, so keep the original size unless the system has been designed for a change.
Q: How tight should the belt be?
Follow the engine maker recommendation. Too tight shortens bearing life and too loose lets the belt slip.
Q: How do I know the pulley is worn?
Look for polished or widened grooves and a belt that sits low in the groove.
