Can you help me out and tell me how to get this BB out on my 1989 CR-7? I know I need to remove the circlips but I'm confused on the need to hammer the spindle (directly) out or what? Also, I'm not certain what order the BB goes back in. Did you use loctite on the BB shell? Also, why did you undo the bolts fixing the rear triangle? Sorry for the questions, but your were very meticulous on your restoration and I hope you can get back to me.
Hi Charlie, thanks for your compliment.
I am not expert like other big brothers here and it was while ago but let me try.
>I'm confused on the need to hammer the spindle (directly) out or what?
When the sealed bearings are originally inserted, loctite was used on the outer surface of the bearings and glued, if you like, against the inside of the BB of the frame.
After you remove the circlip, due to the loctite, the bearings will not come out loose.
So, you need to hit the spindle from the side to push out the bearing to the opposite end (hope it makes sense)
If you reuse the spindle, please use wood or rubber hammer, or use metal hammer with wood on the spindle end to protect so that you don't damage the end and taper of it.
Obviously you need to wack in two stages to remove two bearings on each side.
>Also, I'm not certain what order the BB goes back in.
After cleaning all the parts and inside of BB shell/tube, use loctite on the outside of one of bearing.
Inset the first bearing on either side of BB.
Insert the spindle from other side (I can't remember if loctite is needed on the spindle sorry)
Pick up second bearing, use loctite and insert into the other side of BB.
Insert the second circlip.
When inserting the circlip, need to be careful not to damage the rubber seal of the bearings.
I compromised and scratch the outer lip of BB rather than damage the bearing, then I touched up the BB lip.
>Also, why did you undo the bolts fixing the rear triangle?
This is because I needed to paint the front and rear triangle separately by powder coating.
If you don't need to paint or, you are happy with masking, then you don't need to undo the bolts.
CR-7 is great unique bike in my opinion and it is worth restoring.
I look forward to see yours very soon here.
