Hey,
I need to get some bearing retainer compound on my bearings in the carbon link on my Orbea Oiz.
There's one bolt I can't remove, I'm assuming it's a pivot axle with a threaded sleeve, and its just seized on the bearing.
Anyone remove this pivot before? Did you just drift it out?
I've removed one side of the axle.
Nope, defeated me as well! I could get one side out, but not the other, and vice versa.
I am aware this is not much help, and I'm hoping someone with the correct knack pops up.
There is zero play or roughness in mine due presumably to its position - I've had to replace the others twice in a year.
Just recently did the bearings on my Occam for the first time. I ended up getting the puller kit from here:
Bit of outlay but did the job well apart from one bearing which was so goosed it fell apart leaving only the outer race. Tried loads of ways of getting it out and eventually managed it by bench grinding the wings off a spare star nut to take a bit off them and then tapped it in with a hammer until it caught the lip and then drifted it out. The joy when it finally came out!
I also struggled to get the pivot bolt out. There was a small hex bolt, then a collet but it looked a bit different to that picture. The collet I managed to get out by putting a small socket that was a fairly snug fit into the hole and tapped it side to side and eventually it popped out. Took a while though.
Exploded diagrams are in the manuals
Appears to be a female threaded spacer sleeve between the two bearings.
Is it possible to fit a puller or expanding bolt through the bearing which could expand to grip the spacer sleeve so the other bolt could be undone?
Ok figured it out!
There's a bolt either side of the frame, and a threaded sleeve in the middle.
Remove one bolt from one side, then insert a 5mm Allen key half way into the sleeve. There's a 5mm hex right in the middle of the sleeve. So, you pop a 5mm key into the sleeve, then remove the other bolt.
Simple!
Odd design, as you can't see there's a 5mm in the sleeve, as both bolts are 5mm too.
Got to love a bit of late night tinkering when it goes well.😁
It's when it doesn't and you go to bed festering over the irksome half completed job that it isn't.Lol
