flywheel starter ring

Anonymous-0 · Feb 8, 2009

I have a super A. The flywheel starter ring has gotten worn to the point that It needed replaced. When inspecting the old ring on tear down I cant see any reason why it would ware so bad. The starter seems to be pushing the starter gear deep into the teeth, still in certain spots the ring gear teeth are wore to the point where it wouldnt bite. Is this normal to have to replace a gear over time? Should I be checking something else? My tractor has been converted to 12 volt. Do I have too much push on the starter bendix??

Thanks

The reason why the wear that way is because when you shut it down it stops pretty much the same place. I.E. one area of the ring gear gets hit most of the time by the Bendix kicking in so it wears more in that one place

No, i think it is just normal wear and tear!
I worked in a Ford Dealer mechanic shop, many years ago,and occasionally, a car would come in, needing a new ring gear on the flywheel. And, it was usually a car belonging to a local town resident, who did a lot of starting of the engine!
When you shut off any engine, it usually stops revolving when it is not on the compression stroke, which causes wear when you go to restart it later.

Old is correct. Put a clutch type drive on the starter when putting it together. JimN

Joe: What is normal wear. Quite different for the guy that starts once or twice and works the tractor all day, compared to the guy the starts his tractor 25 times per day. A starter only works when starting the tractor, same as a gear shift only works when shifting gears. It was quite common to wear a shift lever every 5 years on a loader tractor, probably shifts 100 times for every time a field tractor shifts gears.

I doubt if this is the first time your Super A ring gear has been changed, probably not the second time either. These tractors are pushing 60 years old. From experience with working tractors, ring gear every 12 to 20 years, depending on operator habit.

Definitely do as Jim said, throw that Bendix in the garbage, buy a clutch type starter drive.

All good advice below.

An engine will come to rest when shut down when the last two unfueled cylinders find a balance between compresion and exhaust. On an inline four-cylinder that means that the next time it's started, the starter gear will bite within two fairly narrow ranges on the ring gear, and you will see the wear in two spots pretty much opposite each other.

Replace the ring gear and go with the new-style clutch-type starter, and the whole rigging will outlive you.

and another thing is 12 volt starting does nothing good for the ring gear or bendix.it engages lots harder than the 6 volt.

rustred: That is the reason for the clutch type starter drive. It will work just as well on 12 volt as 6 volt. Anyone who has ever had a Clutch starter drive on these tractors, can only think one thing. Go to the deepest canyon or mine shaft and drop the old Bendix.

Hugh, faied bendix is operator error. If the starter motor spins out and engine don't catch, please wait for the motor to stop spinning before hitting the switch again.

Howard: On these little C-113 and C-123, if the compression happens to be down, thus not likely firing up as fast, the drive doesn't have to miss engaging to over speed the starter. My 130 threw whindings from armature, and that clutch drive hasn't missed in 18 years. The compression did drop off badly in the past year.
