Fast and dirty bearing removal

[KungFooBob]

I've just seen this posted elsewhere...



It's an oldie, but I'd not seen it before.

Rawl bolt into the centre of the bearing, tighten it up and drift it out

That's exactly how we do Mtb bearings. I e got 5 different sizes for removal tools. They work fairly well.

[KungFooBob]

Yeah, you can get special expanding tools and slider hammers, but this is a cheap nasty rawl bolt!

[Mr. Dazzle]

Only any use for taking them out AFAICT...smashing the inner race 'sideways' an excellent way to fuck a bearing. But yeah, easier than trying to drift it out from the other side.

Usually you have to use the inner race for removal of at least one wheel bearing as the spacer stops you getting at the outer race. Rawlbolts are useful for all sorts - I use them for bar end mirrors. Throw away the feeble standard fittings, drill the base for 10mm clearance and away you go.

Every wheel i have done i always had a lip going in on the other side to tap them out going round or side to side and top to bottom.

Zx6 does yeah. None of the Mtb ones do though for sure, hence me having loads of

I dare say they are 100% neater and less crude but for me would see it as a waste of cash considering the amount of times i need to change the wheel bearings

The guy in the video is using a rawl bolt, they're like £5 for a pack of ten from screwfix.

I reckon I do 20+ bearings a year on MTBs.

My frame has 8, wheels 5. That times 2 bikes and that's 26 if only doing once a year lol. That's not including headset or bottom brackets but neither are this type of fit or tool.

I think each tool is £13 and bearings from £3-9 a pop.

Where as i have something i could use in the shed and not have to drive a 50 mile round trip to screwfix. Last bike wheel bearing i changed must have been 8 years ago.

Aye. Probably if i did a lot of trail bike riding on dry sand or the like they may not last as long it may be more beneficial to own them.

I've got a set of blind bearing pullers but to be honest the technique in that video looks more effective and is certainly quicker. By the very nature of bearing removal you're going to damage it to the extent you don't want to use it again, so I'd have no qualms about using that method. As long as you can find a rawl-bolt of the correct size you're golden.

I spent a while drifting out the bearings on my trailer this weekend and it's just occurred to me that I bought a bearing puller just after the last time I did this so I wouldn't have to do it again. What a plum.

[weeksy]

I did 4 on a Mtb this weekend. Bashing wasn't working at all so had to push them out, takes longer but less brutal

I'm just sitting here now wondering/worrying if my 406 beater needs the wheel bearings changed (it's been at least 110k miles ...)
