Volvo Jabsco water pump 'drive isolator' 1968 SMF

[nomagic]

Anybody know the actual name of this part? Have guessed at drive: Isolator, bushing, clutch, dog no luck finding it. Is on backside of pump that slips over the crank. Clearly there to isolate the pump from the engine by meshing the drive dogs on the crank and pump.

SMF should SBF (small block ford) can't figure out how or if I could edit the tile

Ayuh,..... That's the isolator of a lovejoy coupler,....

Yeah it is !! Thanks, that opens up a whole new world for my search!

These might generic enough that I could find one, but considering trying to make on out of Delrin. Any opinions out there on the viability of that plan?

drill through for shaft, cut out dogs with jigsaw and clean up with dremel...could it be that simple?

Then newer applications typically have torque arms....I'd be incline to go that route....

To close the loop on this one:

Lovejoy not responsive to e-mail but made a call, narrowed down what is likely the replacement. Material is Buna-N rubber which handles the heat, RPM and torque requirements.

Local distributor in St. Pete is Terry Bearing (they are a 'go to' for many items).
