The new to me 47 Model A starter grinds occasionally. I took the flywheel cover off to have a look. I couldn't tell much before the rain started(too tall to fit in the shop). The bendix looks like new and the PO said he had replaced it. The ring gear has been flipped, the outside is chewed pretty well.
I watched a YouTube video of a guy who took a starter out. I noticed there appears to be a lever that helps push the bendix out. Do those parts wear to the point they don't line up well?
I've rebuilt plenty of starters over the years in garden tractors and old Ford trucks. This looks like a big dog.
What are the common problems with these? I'm just looking for some advice before I try to tackle it.
It's a mechanical bendix, so when you step on the pedal, do it like you mean it. If the ring gear is in good shape, and the starter gear looks ok,you shouldn't have an issue. Disconnect the battery and engage the starter. Do you get full engagement? Is it binding? The starter drops out with two bolts from the bottom. It is big and heavy.
It does seem better when he mashes it down. I haven't had a chance to look at it again yet.
The foot pedal to the rod going into the flywheel cover seems a little loose. I'm guessing that's likely the case with the rod at the cam lever also. If that's the case maybe we can tighten that up a little and get the gear to have a little more zing into the flywheel. Maybe I'll be lucky enough to find a loose bolt.
Man that thing runs good. He drives it around the farm about everyday.
