301 injector pump

[B Learner]

I have a Case model 301 with 4 cyl diesel engine. The fuel keeps draining into the crank case. I was told it is the front seal leaking does anyone have a break down of the injector pump. It is an American Bosch with several tags psb4a-80l,3875a1,ser #7c14913 3494a rpm 1800, cust part 157f-275. Thanks I would appreciate it.

The seal that needs replacement should be done by a diesel shop as the work to replace it is usually out of the normal person's league. On the ones I have seen you have to remove the shaft in the pump to get it out.

I was quoted here that a pump overhaul would be $1800, you can find used ones on eBay for a lot less but make sure you match ALL the numbers as they might look the same they are not.
