Psb injection pump seal kit

[ljm]

I have a Cockshutt 550 with a psb injection pump.

I am looking for the seals. Either orings or the square rings to seal the hydraulic head.

Does anyone know where I can get them?

Thanks
Lloyd

It would help if you could get the pump's part number off of the pump's data tag.

The kits and most of the parts for these went out of production years ago. Having the part number (designation) will help piece the thing together.

This might help to some degree - parts breakdown of the PSB4A. For some seals you can look up the Bosch part number and Google will help you cross-reference it (or you might still find the original). Elsewise you may just have to measure and match on your own. Make sure you replace the seal for the lift pump shaft while you're working on it: They're easy to access, the most common seal to go, and will dump a pile of diesel into your crankcase when they go. Bosch/Ambac part # is PK7910 and still available. But usually much easier to find the SKF equivalent (SKF #4231) or another equivalent.

I got the kit for my PSB pump from Spencer Diesel in Iowa 3 or 4 years ago. Call with your complete pump model number so they can get you the correct kit. That’s all you’ll find for it. There are no hard parts available.

KT 76278 or 79 should have all the head seals needed.
