Re: help with parts
Oooh! Some of these parts are not available for small engines. Try Franz at the Chrysler crew. If he cant help, a lot of these seals were standard parts. If you can look up a bearing supply store near you, carefully remove the old seal so as to not destroy the numbers. A lot of times, the bearing supply house can order them for you.
A couple of examples: The crankshaft upper bearing on 3 and 4 cyl cranks is a bearing used in the rear ends of Ford rear drive vehicles. The upper drive shaft bearing fir a 1984 55 hp Chrysler is a standard bearing for meat processing machines. So: don't give up hope.
