I just split the cases on my TY 175. Everything went smoothly except when I finally freed the crank, the right side main bearing came with it. It is stuck right up against the flywheel. So far I've come up with the following bodges:

Put the crank in the freezer before re-installing it in the cases.

Warm up the cases and refrigerate the crank before re-installing

Use a torch on the case before re-installing.

I really don't want to destroy the main bearing, it feels perfect, but I don't relish the idea of trying to pound the crank and the main bearing back together...at least not without so heat and/or refrigeration.

Do you guys have any ideas??? As you all know, there is no room for a puller between the flywheel and the bearing...

Thanks in advance

This is what you need. http://www.enerpac.com/en/industrial-tools/mechanical-hydraulic-pullers/bhp-series-bearing-puller You really got a 40 year old motor and not replacing mains and seals?

That is a very cool tool. I even found a distributor in San Diego...unfortunately the tool is $173.00...plus I would pay roughly 1/3 more to import it to my home in Mexico....so it looks like a reach. What would a brand new crank cost???

I will certainly be replacing the seals (I have them in hand)...and the bearings if I can get this one off..

Thanks

Mike

You can get them a whole lot cheaper. I was just showing the style you need.

Thank you lineaway......I'll be ordering from Harbor Freight just as soon as I post this supply. I've got a lot of stuff in my garage. Usually stuff that I will only use once...but I also got a hydraulic table to raise the bike up off the floor and some painting supplies..

Thanks again

Mike
