Don't do this. The input shaft does not / will not support a thrust load from the rear output shaft. All the thrust will be taken up by the front and rear bearing if you do it this way.

The propane torch trick works great. I would probably just use a plastic gear. Millions in service without issue.

This is good to know and I certainly don't want to cause unnecessary damage....very much appreciated.

Use the steel gear, not a big fan of the torch method, I use a piece of 1 1/4" pipe about a ft. long and tap the gear into place, make sure the taper on the I.D. bore goes on first...

Been doing it that way for over 30 years...

Hope this helps... Crash

"not a big fan of the torch method"

Me either. Plan is to use the oven I use for powdercoating, heat soak the gear to 450-ish which should be plenty and then tap into place with a section of iron pipe.

I really appreciate everyone's input...and especially the "don't do this" parts.

What's wrong with the torch method? It's worked flawless for me every time. The gear is really soft, and I was always worried about dinging up the teeth if the pipe moved on me.

Heat / torches are used to install press fit hubs onto shafts in industry every day for good reason. More than one way to skin a cat though....

To the OP: If you are heating to 450 deg in an oven, you probably will not need the hammer - just pliers. It's not that tight of a press fit.
