Default Clutch bell stuck on engine?

Hey guys,

So I am getting new clutch bel and obviously want to take the old one off but if wont budge. I even took plyers to it and it wont move? What I think happened was that some loctite from my screw go onto the bearng and its just stuck to the rod. Should I try the heat it up or what?

Try to get an xacto knife to try to pry it or something. Remember to shim the clutch bell right or you will eat clutch bearings.

first you need some kind of small pulley puller from a auto parts store or a flywheel puller. then thread a longer screw into the crank but leave it stick out 3/8 of a inch. then u will be able to put the puller on the back of the clutch bell and tighten it onto the screw to pull the bell off.

hold a lighter to the clutch bell bearings, it should melt that loctite right off, then pull it off with pliers

Your clutch shoes may have worn a groove into your clutch bell and that's what is holding it on. I wouldn't think a little locktight between the bell and a bearing would make it hard to get that thing off. Your best bet is to get some sort of puller or see what you can do with a screwdriver

Humor me, and check to make sure one of your front shims didn't get caught in the groove for the E-clip...that would lock your bell on the shaft. A simple push with a small screwdriver on the shim will free it, with your clutchbell.

I have had this happen before(I dont use loktite there) & wondered what the culprite is? When your bearings over heat some times the bearing will stick to the crank ,I just was always able to get the bell off with a little work but never found a good sounding awnser what the "stick" is other than galling but the discolored part of the crank where the bearing was, mic's the same as the shiny part of the crank.

Surfaces with a very fine surface finish that are clean and tight together can weld to each other. It's caused by the process of electrolysis. It could also be caused by galling which is a product of friction between the parts. In both cases, the solution is to apply a very light layer of grease or oil(insulator) on the shaft before sliding the bearing on. Most of the time this will prevent future problems. A spray on moly coting also works well when applied to the shaft.

So butch man how did you get it off? I tried putting a lighter on the bearing and heating the clutch to 200 and I still couldn't pull it off. Also I cant get a screw driver behind it to pry??

If the bearing is what is holding the bell on, you could try putting a sleeve or socket over the shaft that will seat against the inner race of the clutch bearing. Give it a couple of light taps with a hammer to break the inner race loose from the shaft. Then you should be able to work it off. I would not reuse the bearing.

If you think is loctite holding the bearing on you must heat it to 300 degrees minimum.

it's actually not electrolysis. It's called cold welding. When finely polished surfaces come into contact with each other, they want to bind together. This could cause that bearing to lock into place.

How would I put a sleeve or socket over the shaft when there is no shaft exposed?
