Read wheel bearings removal

[grommit]

Got to replace rear wheel [ball] bearings on my GenI FJR (due to suspicious noise coming from the rear end).

Having no special tool at hand I tried several methods of pulling / knocking these bearings out of the wheel. The method that finally worked was to make use of a 22mm diameter anchor bolt mounted into each of the bearings in a one-by-one fashion.

The anchor and the [new] bearing:

Mounting anchor into the old bearing in the wheel:

Knocked out the old bearing by working on the anchor bolt with a steel shaft through the axle hole:

Hope this helps someone.

I've taken a LOT of bearings out of all kinds of vehicles and machinery; That is definitely a unique idea!

You, Sir, have my deepest admiration.

Fantastic idea, I'm hanging onto this one.

Thanks,

Ingenious!!

Neat idea. Where did you get a 22mm anchor bolt?

I'm not sure you want one.... questioning the OP, the ID of the rear wheel bearings is about 0.785", so wouldn't we want a 3/4" or 19 mm OD anchor bolt?

Very crafty sir. I did it the hard way like probably many others, I wanted to design a tool to pull them while that same ID spacer washed my design. My wheel bearings were black and toasty @ 42K FWIW, good thing a tireguy pointed it out.

At a hardware store department where they sell mounting hardware (like screws, bolts, nuts etc).

The outer diameter of the anchor should in fact be slightly less than 22mm (perhaps 20mm would work fine) to let it easily into the bearing. The best way would be to take your new bearing to a hardware store to select the best fitting anchor.

That's a confusing issue. I've googled the specs for 6204 & 6304 bearings so their inner diameter is 22mm. However, my bearings measure to 21mm at most. In any case I guess the 19-20mm anchor bolt would work fine as it expands in its working position.

Great idea!

I think your other suggestion is a good one, take a bearing to the store with you and match up an anchor bolt. They are not likely to be that precise in their nature, and we're not using them for their intended application. Great idea though.

Very clever!

Thanks.

Heck, I was had right from the name and avatar. The bearing puller was just a bonus.

No crackers, Grommit!

One word: Brilliant!!

:lol: :lol:

Great idea there Grommit!!

Thanks for sharing with the rest of the crew. :clapping:

I was seriously puzzled by the Cyrillic on the bolt, until I saw your location! Awesome idea.

One more hint - I found it handy to knock the bearings back into the wheel using plastic waterpipe fitting like this:

.

There are many shapes and sizes of these fittings out there, mine was a little too large in diameter so I had to cut some excess material off it.
