62 needs a new ring gear

Postby zimo29 » Tue Nov 26, 2019 1:27 pm

I need to replace the ring gear. Is there a video of how to? Or does someone live near Sturgeon Bay, WI with spare time that knows how to take my tractor apart?

Thanks,
Don

Sometimes you can just heat them up with a torch and flip them over.
I've heard that some people have success just rotating them 45 degrees,

Above topic should answer most of your questions.

Edit. Rereading the topic, information desired on splitting the tractor? How To section of this site has quite a few suggestions and information on how to split the tractor and remove the flywheel and then the ring gear.
I have an excuse. CRS.

Rear end ring gear, Once apart file the mating surface then stone it with a flat fine stone to make sure it’s perfectly flat, even the ring gear surface. Once it’s assembled check the carrier and ring gear seam with a .001”/.0015” feeler gage to make sure the two parts are mated properly.
New gears we put white grease to check the pattern, then bluing on the teeth 90 degrees apart Incase of a failure we check the running pattern and the machining.

That’s how we do it in the machine building industry

Flywheel ring gear use heat then clamp it in place. Once cooled check with feeler gage.

The flywheel ring gear is easy enough to change, just knock the old one off, heat the new one and drop it on. Many people advise flipping them over but I disagree. The front side of the ring gear tooth has a relief cut that helps the starter gear engage the ring gear. The back side of the ring gear does not have that relief meaning possible starter engagement issues. A new gear is not that expensive!

A gas bbq grill works great to heat the gear as well.

Yes, I agree! That grill is good for a lot of shop projects.

That's a lot of work, when a little touch up using a .046 cut off wheel as a grinding wheel in an angle grinder can re3sHPE THE WORN TEETH IN THE 2 SPOTS WHERE they always get worn will take care of it for many years.

Hi,
Below is a pic from TM Tractor of the Cub flywheel, and a pic of the ring gear.

The ends of the ring gear teeth get battered from the starter gear engaging them over time.
If the teeth look good, and the ends are battered, like in the pic, you can grind the end of each tooth to remove the material that is battered over, and restore the correct angle of the ends of the teeth. :)
