I'm going to change the gear ratio from 7.91 to 8.18 in my Tempes 3D, so I have to install the new 0864-13 11T pinion w/Brg Inst and take out the one installed.

Is there anyone that can tell me the best procedure to do this job without destroying the old bearing/pinion? Do I need some special tool?

PLEASE HELP!

i will assume you are talking about the bearing that hold the pinion to th start block. you will need to heat the block in order to get the bearing/pionion out. then heat the inside of the pinion to free the bearing. if you are going to reuse the bearing becarefull on the amount of heat used . just enough to soften the locktite. if you trash the bearing , it is the same bearing used in the extreme blade holder. the pinion should unthread from the bell with very little heat. just make sure you locktite everthing back in place. hope this helps.

Thank you Roy, I'm going to use a new pinion with the new bearing already installed. One question: do I need to use a torch or a good heat gun is sufficient? Also what you mean when you say "inside of the pinion"? If I can I would like to "save" the old bearing.

Thank you

A good heat gun is really better than a torch. You'll be less likely to cook the grease out of the bearing.

Note: Pinion gear bearing is NOT the same one used in the blade grip. It's a 0183 or 0184 of the same dimensions as the one used in the mainshaft bearing blocks.

when heat treating parts, i just let them heat up in a cooking oven as much as needed.

I found it is easy just to preheat you oven to the timp you want. Stick them in for a few minutes . Pull out and smack on a binch.

Ovens work well as long as you're careful not to dislodge parts that you mean to stay in place.

I've wanted to ask Loctite what happens to the strength of the loctite bond IF you heat a part up to within the range that the bond will separate but do not actually break the part free. Is the bond after cooling the same strength as it was before the heating????
