Drum brake performance kit

Dean · Jan 23, 2016

When I fitted the new pin for the performance kit mod I didn't have a drift and didn't want to pay to have one made. I used a 0.750 (20mm) ball bearing. Cost $5.worked a treat. Put plenty of EP grease on it into the press... Job done. Maybe it will help someone else.

That may be what they used on the press tool, a ball bearing welded on a shaft, for this job :!:

This is what is recommended from old Brit. You need to be careful using a ball bearing. It is easy to over swage and you could damage something.

When confronted with the same problem, I mailed my backing plate and pin to Fred at Old Britts and he pressed it in for free. Nice solution with the ball bearing though and cheaper than my postage. BTW, the performance kit really made a difference with new shoes.

I placed the round end of a ball peen hammer on the rivet and hit it with another hammer. :idea: Worked fine for one of those things you do once or twice... Amazing how often you use a hammer on these bikes.

Well said about the hammer. Really got me thinking on how many time over the last 44 years of Norton ownership that I have used the old reliable hammer to nudge, modify, or just smash something to bits .

Timely post, as I'll be doing this in a week or so when my kit arrives from clubman...

on another note, anybody have an idea of tolerable hub runout? I've just installed a new set of sealed bearings into the front hub, job went smoothly and I'm pretty sure I drove bearings square, but an amateur bench test (no dial gauge) shows quite a bit of hub runout

Mr Spindler, my old metalwork teacher always warned against knocking two hammers together because the hardened faces could chip and send a shard of steel anywhere. I had a lot of respect for that man and went into engineering as a result of his teaching.

Couldn't help but remember your post while "nudging" apart the frozen halves of this fork leg this afternoon. Outcome was very uncertain.
