401 flights.....repro techmatic bb

McQUEEN:
Having problems with a set of single pinch Redline flights with a 19mm spindle and a repro techmatic BB......



I've had these flights around 6 months and just bought the techmatic repro BB - all seemed good and started unpacking ready to build up a RL20, but found that I couldnt get the bearing cones/adaptors onto the spindle.

The chain wheel side goes on about 3 turns, then locks and wont go any further, and on the other side, the lock nut goes on fine, but the bearing cone wont go on at all. They all seem too tight?



Has anyone got any ideas? The threads on the spindle look a little worn (they are 30 years old!) but the last guy had no problems?

adenough:
is one side a left hand thread, i.e. anti clockwise to tighten?

McQUEEN:
I've got the thread direction all correct........I remember it was the same for one piece BB bitd!

adenough:
Hammer?  :LolLolLolLol:

deeman:
If they have a 19mm spindle it sounds like you have Redline prolines and not flights.The Techmatic will have been made for flights.I could also be wrong!!! :idiot2: :daumenhoch:
Sorry I can't see the pics atm for some reason
