Super C starter

Charlie M · Sep 17, 2020

I've got my new to me Super C running pretty well after unknown years of sitting in a hedgerow. Something still needs work is the starter. I have to try a few times before it engages the fly wheel and when it doesn't it just has a grinding noise. Am I right in thinking it just needs a good clean up of the contact areas and maybe brushes after years of sitting idle or is the grinding noise a sign of a bigger problem? When it finally engages it sounds OK. I don't know if the local shop I've used in the past is still open so I'm thinking of opening the unit up and clean contact areas myself.

Pull the starter off and look at the starter drive gear and the flywheel ring gear. Good chance one or both have some messed up teeth. Engine tend to shut down close to the same position every time shut down so that area of the ring gear get the most wear so in turn causes problems over the years

I know the ring gear is good as I had the flywheel off to change rear seal and after that replace the clutch. Don't know about the starter gear. I had the starter out and don't remember the gear being bad but that was last spring so lots of time to forget.

Also enough time for the starter drive to rust up and get sticky

Newer style drives are more efficient than the original type that came with the tractor when it was new. For the cost, I'd replace it, drives are not that expensive.

And sold right here on YT. Two things prevent a inertia drive from working (other than being physically broken) one is gooey sticky gummy lubricant on the splines of the shaft, the other is low voltage preventing high inertia starter motor spin up. If it cranks nice and strongly when it does work, it is likely goo. Jim

Yep, get the drive right here,they are cheaper than most and are made just as good as the higher priced ones. I put one on my SC this spring.

Yes I would give that a good cleaning maybe with something like spray carb cleaner working the gear around to work it up in the drive "threads". Then maybe a light coat of something like 3 in 1 oil if they still sell that, I know I still have a can of it.

Not sure if I would used something like WD-40, sometimes that can leave a residue that might get sticky.

I replace the bushing. The drive I’ve not tried new style ,yet. I check field coils with vom for ground. I use the vom met chack resistance variation of armature. I have the commutator turned just to clean up , I have had one run out .015. . I have a tool on the lathe to clean out between commutator. I buy nEw brushes .toatal parts cost about 25 .
I find the the starters will perform very well with a good maintenance of all components, I have seen the starter switches give poor contact to starter field post clean the soot off and file smooth . I have had solder loose on field contact and resolve red with big soldering iron, hard to do
If you want watch the excellent video on lathe turning commutator With clausing Lathe by turbo cane on u tube ,it is excellent. Follow that and you will have a great armature .
