mmmexico Posted March 4, 2014 Report Share Posted March 4, 2014 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...

lineaway Posted March 4, 2014 Report Share Posted March 4, 2014 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? 1 Quote Link to comment Share on other sites More sharing options...
mmmexico Posted March 5, 2014 Author Report Share Posted March 5, 2014 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..

lineaway Posted March 5, 2014 Report Share Posted March 5, 2014 (edited) You can get them a whole lot cheaper. I was just showing the style you need. http://www.harborfreight.com/large-bearing-separator-3979.html http://www.harborfreight.com/bearing-separator-and-puller-set-93980.html Edited March 5, 2014 by lineaway Quote Link to comment Share on other sites More sharing options...
mmmexico Posted March 5, 2014 Author Report Share Posted March 5, 2014 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 Quote Link to comment Share on other sites More sharing options...
