Haha, its just going to be used around the farm some. No precise work. Does a great job pushing though, if I can just keep it from leaking.
If this helps I did find the part numbers for the gaskets, there are two for the starter. One goes between the adapter and flywheel housing and one between adapter and starter nose.
It took a little digging around as according to SIS that model was standard with the gas starting engine but was available as a direct 24 volt electric start from factory.
Also looking at the picture of your starter I see that someone has replaced the starter solenoid with a newer style one. Have to wonder if they did not know the starter was a wet flywheel application and did not replace one or the other of the gaskets when working on the starter.
Back many moons ago the when the local electrical repair shop was just getting going, they are now all over the Eastern State I believe, we had some problems with starters they worked on. see there is an oil seal between the pinion gear area and the electrical area of the motor and they were not too fussy about replacing that seal. It seems they were not aware of wet flywheel designs!
Also had problems with the nose cones for some starters. They often were replaced with nose cones with double sets of bolt holes for mounting to the armature housing to allow one starter to fit more applications. Problem was when used on wet housings they would leak like crazy if no one new about installing the rubber balls in the unused bolt holes!
Guess I got a little of topic but maybe the points will help someone down the road.
