From the closest parts
manual I can find, it appears that there is a oilite bearing inside the flywheel housing for the starter shaft to rest in. If the starter itself is not comprised of a casting that contains an integral bushing to support the end of the starter shaft and gear
(that engages the flywheel), then replacing that bearing would most likely require removal
of the flywheel to generator mating. Or simply put, a major disassembly of the generator.
- - Normally oilite bearings are "press-fit" into position and removal
is definitely not easy or for the weak hearted.
- - For a check the "wear" of the bearing you would need the rotor of the old starter (the rotating part with all the starter casing, etc.) Then you would carefully slide that part down into position into the bearing and by using sidewise pressure see if there is any "slop" in the bearing. That is, like taking a clevis pin and inserting it into its position and seeing if you have any sideways movement of the pin because the hole for the pin was worn or enlarged due to wear.
- - The only way to know for sure if and how that bearing is would require a photo
of the starter showing the end with the actual starter to flywheel gear
. Without that photo
we are just guessing.
