Headset bearing adjustment.
« on: 16 February, 2018, 17:15:40 »
I started with a bare frame, new abutment rings, new bearings fitted and new stanchions. I have fitted the fork legs and front wheel. The problem I have is the final adjustment on the new setup. It is all too heavy to feel the adjustment. Worried about over-tightening.  Any tips please. 1971 A65.

Normally, with the front wheel off the ground, you should be able to feel any free play in the head stock bearings - the weight of the front end shouldn't affect this. It's best to start with the bearings slightly loose so that you can feel some initial free play. Then tighten the bearings a small amount at a time until you can just tell that the free play has disappeared.

Another issue is the early ones had a 20tpi nut (the one with the slots in that grips the stem when the top yoke clamp bolt is tightened up). The later ones had a finer thread. As yiu tighten the head bearings, its kind of an on/off point between slack and graunchy. You'll know what  mean when you do it :)

All done, I took the front wheel out and fine tuned the bearings; all is good thanks.
