I'm having fits trying to figure out how to remove the inner cam bearing that's deep in the head of my Warrior. My local shop recommended heating the head in an oven to 350 deg and then it'll come out easier. I've done this type of thing before but was concerned about head warpage.

Any thoughts on this ?

 

Probably be ok if you didn't leave it in to long. Just heat it up enough to help it expand some. Probably no more than a few minutes or so needed to accomplish what you want. jmo and I'm no expert. I am not to be held liable for any damage. LOL I think I'll put that in my signature. LOL. Hope you get it to work for you.

 

The head gets pretty close to that temp anyway..

Gradually bringing the temp up would be best.. meaning dont preheat the oven.

Are you using a bearing extractor??

 

Wsh,
No sweat, I'll blame my local shop

007,
I'm currently shopping for a slide hammer type inside puller. I need a small one - the automotive type look pretty large. The I.D. of the bearing is 1". Any suggestions as far as a source?

Thanks, Eric

This little Warrior project is gonna drive-me-to-drinkin ![img]i/expressions/face-icon-small-shocked.gif[/img]

 

I would look at Motion Pro or Snap-on, betweent hose too I bet you could find one. And then there is always the local stealership.[img]i/expressions/face-icon-small-disgusted.gif[/img]

 

Like 007 said heat it slowly do your work and put it back in the oven and cool it down slowly.

 

What do you guys think of this:

Puller

Heat it up slowly and since the I.D. of the bearing is 1" this should work - comments ?

 

Humor the ignorant please.

How does this tool work? [img]i/expressions/face-icon-small-confused.gif[/img]

Once inserted inside the bearing the jaws spread against the inside of the bearing and then you slide the black handle portion away from the bearing quickly and hitting the red handle? This is enough force to remove a pressed in bearing? I could have used this tool on my cases when I had to swap the bearings out. Wound up just buying new bearings for the ones that required a tool like this. [img]i/expressions/face-icon-small-blush.gif[/img]

 

When I painted my engine I baked the paint at 400 degrees for 3 hrs to "cure the paint. When pulling my side cases out, I noticed that every bearing fell out of the case! [img]i/expressions/face-icon-small-shocked.gif[/img] oops! But I simply put them back in, and have had NO problem. SO GO FOR IT!![img]i/expressions/face-icon-small-happy.gif[/img]







Bigger.

 

I'm learning too !! Yep - that's the basic operation. You can flip the jaws to grab things from the outside too. They are apparently pretty common in a bigger version for automotive applications but I need a smaller style to get inside the head.

I checked the service manual (cover-to-cover) and there is no mention of this tool or the method of removing this bearing. It's a roller bearing with no inner race and the "hooks" should grab the lip on the outer race. This is the best tool I can come up with ? There is absolutely no way to tap or pry it out since it's in a blind hole down in the head - it's pis&&in me off !

This tool seems to fit the bill - I hope.
