Triumph Bonneville T140 - Front Wheel Bearing Replacement

The 46 year old front wheel bearings were a bit crunchy...

Reminds me of why we bought shielded bearings for our skateboards when we were young… nicely done mate, lots of great info on your channel. I have a 76 T140. Thanks for your efforts!

If only there was some sort of nipple where we could force grease into it to lube the bearings… 🧐😂 Thanks.

@@bodganeering there’s a thought! Probably won’t have to do that again for quite a while though!

Good informative video, nice to see you have those invisible voids where you can’t see things right in front of you 👍 What size socket did you use for the smaller bearing drift? And did you refit all the bearing dust covers with the new sealed bearings?

[@bodganeering]

I can't remember what size socket I used to drive the bearings in with, a pretty big one. But you can also use a brass drift as I did on the second one. As for the dust covers, I fitted them on one side as they helped space out the bearing in its housing, I know some people don't bother with them. I'd say that's your call.

I'm lucky that I haven't had to do this to my 78 T140V yet. After 60000 miles the wheel bearings are all still good, but mine has never had anyone else interfere with it. One thing I might have done differently is put a couple of the disc bolts back in to clamp the two halves of the hub together, otherwise you are relying on the spoke tension to hold them in place while you knock the bearings out.

[@bodganeering]

Good call on the bolts. This bike has only done around 25,000 and it looks like the bearings have never been looked at, doing the rears next so let’s see what surprises are there… 😂

12:04 could you not use outer part of the old bearing race with saw cut across it to drive the new one home? Saw cut allows you to get old race out again.

[@bodganeering]

You could but a good bearing fit would make it difficult to get out.

[@AaaaandAction]

@@bodganeering ……. Which is why you put a cut across the race. Done it many times on many bearings, last month on an Ifor Williams wheel bearing.

You have got to be joking. Why do people like post this sort of stuff for the world to see you the incorrect way to do repairs to classic bikes.

[@bodganeering]

The method used is as described in both the Triumph workshop manual and the Haynes book of lies. Could you please enlighten me on the correct method?
