OK I know not to look a blind bearing in the eye, but my question is which tool should I get to remove them. I rented a slide hammer bearing removal tool with collets and it worked good so I think I would like to get one. I don't know what to look for in one of these bearing pullers. There are some for 50$ and some for 150$, I am really used to getting used tools so if I can find a good one cheap that would be my best bet. Once I learned what a blind bearing was every damned bearing I had to deal with was a blind bearing.
Any help or suggestions appreciated, thanks folks!
By blind bearing, I'm guessing your talking about something like a pilot bearing, where you can't get at it from the back. I go with free tools, a dowel or such that just fits in the hole, and some grease or wet paper in the cavity.
What's the inside diameter of the bearing?
I used one for a bearing in a BMW 2002 transmission, it had about 20 little fingers that went in behind the bearing, expanded only 3/16" and then jacked it out. I borrowed the tool.
If it's a small diameter, do what you would with a pilot bearing: Fill the inside with grease, find a round bar that slips inside the bearing and then whack the snot out of it! Greas is not compressable, it pushes the pilot bearing out.
What's the bearing in?

agreed. the rod + grease + hammer trick has worked for me so long as there is a sealed cavity to fill such as the pilot bearing scenario.
I have a OTC brand tool it has never let me down. I tried a Harbour freight special. Broke on first use
I am looking for a bearing/rubber seal puller thinga majigy. I rented an OEM puller, a few whacks later and out came the swing arm bearings on my bike. I'm just starting to keep an eye out, I found a nice set last night from motion pro but it is like 170$ which is out of budget right now.
A blind bearing is just one that you can't get at from behind. There are roller bearing and wheel bearings that need this tool to be removed. I never heard of the grease and rod trick, now I'll keep an eye out for a bearing to try that on. Unfortunately I think I've almost done or had done about all the bearings I'll need, but I'm on the lookout for the slide hammer tool.
Thanks for the replies and suggestion, I guess I'm just not imaginative enough!

We have the SKF ones at work that grab the inside of the inner race we also have a SKF one that goes inside the ball path of the outer race for the bearing that have blown apart but work great never worrie about braking them as there true quality tools but i know they were not cheap.
Nothing worse then thinking Ah it's an easy job to find you don't have the right tool or your cheap tool busted...

Brilliant!!! Absolutely brilliant!
Wish I had known this trick when I did the clutch on the SC two weeks ago. I ended up cutting that one out with a jigsaw because the puller I cobbled together wouldn't budge it.

A friend taught me to pound in bits of crayon. Doesn't make the mess grease does and leaves you with a neat round multicolor crayon.
...or drip it full of candle wax.
