ring gear remaval with out a torch ???

SDE · Aug 6, 2016

I would like to flip the ring gear, before I put the engine back into the tractor.(9n)I do not have a torch. If I pay someone to remove it, I might as well buy a new gear and break this one to remove it. Can it be removed and replaced safely with another method?
Thank you

Several vehicles have to have components heated in an oven to make them slip fit, can you stick it in an electric oven instead of torching? I'm not sure how the normal way to do it is but for heating big things a cheap old weed burner or roofing torch works fine. You don't want to be getting up into cutting temperatures.

It can be done wit ha simple punch and hammer but ti is not fun to do. You have to work your way around it moving it a little at ta time

Well, the idea is to heat ONLY the gear and leave flywheel COLD. That's how you install. Heating the gear "on the flywheel" heats everything at same time . So how's that going to give an advantage?? Use a small punch and hammer and ease on around it a few times and it will come off. THEN if you want to use the heat method to shrink it back on,by all means do it.

Just get someone to come with a torch you go round a few times and it will slide off easy then you can heat it good flib and put back on iv done it any times mess around taking old one off and break it then you still need a torch toheat the new one to install doesent take a lot.

the expansion is a function of the diameter and temperature--so the ring gear will expand more than the flywheel---and if your careful the ring gear will be heated much more than the flywheel

You could use a barbecue with Brickets and get it hot enough..

If I can get it off, I can use my gas grill to get it hot enough to put it back on.

I prefer to knock them off with a husky flat iron and a hammer. That spreads the beating on gear out a little better along the ring gear teeth. No need to heat to remove and they don't have to be all that hot to install. Grill would work fine, or oven. Just quickly get it on as once it touches the flywheel it will start to shrink.

You'd be surprised what you can do with a Coleman propane torch.

If I am heating everything at the same time why is the ring gear red and the flywheel black? It sure looks like the ring gear is a lot hotter, and it falls off very readily. What am I missing?

air hammer with blunt tool. just a short punch on the trigger, move a couple of inches and repeat. Probably one - one 1/2 times around and it will be off. Flip and repeat to reinstall.

You dont heat the flywheel just the ring gear.

When you flip the ring gear over you no longer have the tapered end of the ring gear teeth toward the bendix. Does not engage as easily and has a tendency to burr over the teeth on ring gear and bendix. If you do filp it you really should grind a taper on the ends of the ring gear teeth. Could save you a broken starter drive or shaft.

I've changed alot of rig gears and I've got to agree witg 'ndbjda' below. In other words, check the ring gear and make sure it isn't taper cut on one side, and not the other. If it is then you can't flip it and expect the starter gear to engage properly.

That said, there are plenty of ways to get it off that have already been given. The same goes for putting it back on. The easiest way is to use a propane torch and simply heat the ring until it drops on. Just be ready to give it a few love taps to insure it seats. You can also use the oven, ((with the wife's permission...LOL))) and heat it to about 250. At that temp, it should drop right on.
