Jabsco 11876-0000 Clutch Adaptor
The Jabsco 11876-0000 is the genuine clutch adaptor for Jabsco 11870 series 1-1/4 in and 18330 series 2 in electro-magnetic clutch pumps. The adaptor is the machined part that locates the electro-magnetic clutch on the pump, holding the clutch assembly square to the pump shaft and bearings so the pulley runs true and the clutch engages cleanly.
An adaptor that is cracked, corroded or worn in its bores lets the clutch sit out of line. That shows up as belt wear, a clutch that slips or chatters, and extra load on the pump bearings and shaft seal. Replace it when rebuilding the drive end of a clutch pump if it shows any of these signs, and check the clutch and bearings at the same time.

Frequently Asked Questions
Q: Is it the same for 1-1/4 in and 2 in pumps?
This adaptor is listed for both the 11870 and 18330 series clutch pumps.
Q: Does the clutch need to come off to replace the adaptor?
Yes. The clutch assembly mounts to the adaptor, so it is removed first and refitted afterwards.
Q: What are the signs of a worn adaptor?
Belt wear, a clutch that chatters or slips, and a pulley that does not run true are all worth checking.
Q: Should the bearings be replaced at the same time?
If they are rough or noisy, yes. The drive end is already apart, and misalignment wears bearings.
