dave5.0 Posted July 29, 2009 Report Share Posted July 29, 2009 Clutch basket came apart and one of the fingers wedged itself between the basket gear and crank gear. Took out the crank seal. Got everything apart and don't have any up and down play in the bearing but have some wobble to it. Looks to be just a ball bearing. Don't think it's the hotrod bearing but not sure. Thinking of replacing them anyway. Do they press off and on? Can they be heated to ease install removal? Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted July 29, 2009 Report Share Posted July 29, 2009 Usually press them off, then heat em up in oil and put new ones back on. Quote Link to comment Share on other sites More sharing options...

You wouldn't happen to have any laying around you could post closeup pictures of would you? Looking for the good ones. The Max load and the one with the rollers instead of balls. TZ I think it's called. Quote Link to comment Share on other sites More sharing options...
00tbanshee Posted July 30, 2009 Report Share Posted July 30, 2009 i have changed them before.pull it of with a wheel puller.then to assemble set the crank in the freezer for about a hr or so and stick the bearing in a little oven.not sure what i set it at but just till its pretty hot.then it all will go together really easy with only maybe very little tapping Quote Link to comment Share on other sites More sharing options...
dave5.0 Posted July 30, 2009 Author Report Share Posted July 30, 2009 (edited) That's kinda what I figured. I'm wondering if these cool bearings can be bought at a bearing supplier for half the cost. I replaced all the bearings in my son's little Italian made 50 for about $40. I'd really like to see some of these bearings up close and get some numbers off them to see if it's possible. Alot of that kind of stuff isn't as special as it's made out to be if you know where to look. Edited July 30, 2009 by dave5.0 Quote Link to comment Share on other sites More sharing options...

Alot of that kind of stuff isn't as special as it's made out to be if you know where to look. I know what you mean. Your best bet may be to take the original bearing for dimensions and just see if you can get it in a roller type. I have a spare crank downstairs that I can measure the ID, OD, and Width of the bearing if you need it. I know when I replaced bushings in an old J arm frame front end with bearings, I was able to by the needle bearings from a bearing house cheaper then I could get the bushings for from a the dealership.

SP Thanks, I've got my crank out I was just hoping for some pics that I could get some numbers off of. If I can get some numbers they can look them up pretty quick. I thought about taking numbers off my bearings and seeing if they can cross them to anything. I can't imagine that a 2-3" roller bearing is going to cost $80 at a place like that.

bbcmudtruck Posted August 2, 2009 Report Share Posted August 2, 2009 FAST Racing has max load bearings in stock for less than $50 bucks. I think most people who replace the crank bearings run a stock bearing on one side and a maxload on the sprocket side. Quote Link to comment Share on other sites More sharing options...
dave5.0 Posted August 2, 2009 Author Report Share Posted August 2, 2009 I thought the maxload went on the clutch side? Since there isn't any load on the stator side? Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted August 2, 2009 Report Share Posted August 2, 2009 A max load can be run on both sides. It looks like a standard ball bearing only it has more ball bearings. It could also be made out of a better quality steel or heat treated though. Quote Link to comment Share on other sites More sharing options...

dave5.0 Posted August 3, 2009 Author Report Share Posted August 3, 2009 (edited) Pulled a bearing today and searched the numbers. 6305n seems to be a fairly popular size for bearings. I'm going to take it to Motion Industries tomorrow and see what they can cross it over to. Edited August 3, 2009 by dave5.0 Quote Link to comment Share on other sites More sharing options...
