I have an 83 843 bobcat that has oil leaks. I'm having it repaired and find that some of the gaskets and seals are no longer sold by bobcat dealer. It has a Perkins diesel engine. The dealer said that they are trying to locate the parts and not even Perkins has them. They said the main seal, fuel pump,and pan gasket are leaking. If anybody can give me information as to who might handle the parts I will get it to my dealer. Thanks in advance for the help.

As for the gaskets, good old silicone can be used, no idea on the seal. Is it the rear main seal? or just a std round seal with a spring inside?
I'd be temped to contact perkins directly, or try a few dealers (perkins and bobcat) someone may have old stock around even if its discontinued. Often when parts are hard to find it keeps a really dedicated dealer to keep searching out the usual channels
Do you know the model of the engine?

Thanks for the information. I think they said it was the front seal.. I'll call them again to see if they had any luck and to find out just what parts they are trying to find.

I agree, red or blue high temperature silicone works wonders!!!
As for seals, i'm sure you will be able to source them somewhere, they will be a *standard* seal, but getting the correct size may be the problem but i'm sure they will be out there somehwere. Call around a few bearing shops with the sizes of the seal and they may be able to work it out for you. Even better if the seal has a number printed on it.
One of the problems seals like this have is they wear a groove where the lip where the seal runs on the crank, but this is repairable with a speedy sleeve (a thin sleeve that slips over the worn section). No matter what, there is ALWAYS a way.
Good luck!!!!
