- Help/advice removing blind bearings from rear chain stay.
Deano8 – yes, that’s the basic idea. Find a bit of pipe that fits reasonably snugly inside the bearing, cut a slot in the end then find a bolt that will wind into the pipe and open it to grip the bearing, then drive it out. You’re less likely to destroy the bearing leaving an outer race that’s a bugger to shift if you use this method IME.Posted 4 years agoSimon_SemtexMember
Have only just had to do this job myself this week. Forget the whole making a pipe extractor thing. There is an alternative……
Go to Screwfix and buy the following.
Thrubolts 8 x 115mm Drill Size 8 Max Fixture 60 Pack of 10Product Code: 12799
The sliding collar on the thru bolt slips inside the bearing and tightens. You can then pull them out as usual. Just did it myself on the rear of my Spesh StumpJumper. There is a video on Youtube of “Kaesae” as mentioned before, performing the same trick. (Video is a bit blurry so you cant really make out what he uses but I figured out it was the above Screwfix item.
Good luck and it definately does work.Posted 4 years agonutsnvolksMember
I did the bearings on my stumpy recently. After no joy with bike ships, or them charging stupid amounts of time and money for a 2 min job of extracting the bearing I decided to tackle the horst o es myself. I went to b and q with one of the new bearings for referance and found a rawl bolt that fitted inside, then added a socket and some washers and within a few min of getting home the bearings were out. Easy as can be!Posted 4 years ago
