Here's the pics
Ooh, a helicomatic hub
Looks like a mid 80s frame based on the head tube badge, should be regular BSA threaded BB.
In well I I ordered park tools for both sides of the BB cause I will need them for easier removal. I am guessing the removal of each side is counter clockwise
Next two projects Raleigh Super Record. All complete, got it on EBay for 90.00. I rode these back in the day mine was burgundy and I finally found one. Gonna look new when I'm finished. Other is Iron Horse Zebra. It was free, its cleaned and just got new bearings waiting to install. This stuff isn't high end but for me it's a good time spent.
And here's your first gotcha! moment. The fixed cup (drive side) is going to be reverse threaded, so you undo it clockwise
Wow Gotcha is right. Tks for this before I tried it.
Well I finally got my c spanner, wasn't paying attention during removal, BB fell out. Measured 1 1/2 inches from ring before the taper and 1 7/16 on the other side. I can't believe I did this. So my stupid question is Does the longer side go on the drive side. I also decided not to remove the fixed cup, I have the. Wrench, cup is on there solid and I can clean it and add the new bearings from the other side.
You are right. I just removed the lock ring and the BB and bearings. The Fixed cup is on there solid. So I will just replace bearings from the other side. Tks!
Longer side on mine goes to the drive side, as it pushes the rings out a little bit.
Longer side = drive side. Think you would find it easier to pop the (new) bearings in from the right side, through the hole, having pushed plenty of grease into that cup. They'll stick there awaiting the square taper spindle.
Yup. Unless you're using caged bearings.
Bottom bracket. Mid eighties. Mmmm.
Sounds good. Tks to all.
Here's some good news. I got the wrench from Park Tools for the fixed cup. Sprayed the cup with WD-40. Let it soak in overnight. Just got home, hit it three sacks with the wood mallet and off it came. I count 11 bearings each side and will put some new ones in. I wasn't gonna let this cup get past me. It was coming off.
