After some discussion with a local bearing supplier I bought a 6204 bearing with
a C3 fit rather than the usual C2. It fits perfectly so problem solved.

Having sorted the back brake out on my late Arrow I've moved on to the next challenge. When I stripped the rear wheel the bearing in the sprocket was stuck fast with petrified grease. I pressed the bearing out and degreased it. It now turns but the tracks are badly pitted. It was a very noisy bearin...

Five minutes of filing and bending and five minutes of applied brute force (at which
I'm quite good) and the springs are removed. I still have both springs and a full
compliment of eyes and fingers.

Thanks once again.

Thank you gentlemen. I'll give it a try once I've got a bit further with my tax return. High on the list of people to remain on good terms with is one's accountant along with one's dentist and MOT tester. I've already been the victim of the Revenge of Zebedee over the circlip which retains the sleev...

While the diameters are the same for Ariel and BSA for the headset bearings one
is 'thicker' than the other - BSA I think - and getting the wrong ones can cause
problems.

I've been working away on a late Arrow I inherited. It's been parked under a bench in a workshop since 1979 and has suffered more than a few indignities in the course of its life. I had Arrows and a Leader in my youth, all of which required resurrection so, apart from a fading memory, I'm no strange...

The registration is from Smethwick and I think it dates from 1950.

That is hard braking, presumably to avoid crossing the white line. I like the markers
which look like pistons with poles through their crowns. Some sort of trial?

Could that be a seafront somewhere?

For any engine the more you increase the compression the less ignition advance you need. Most Mk1 Square 4s will have had both head and block skimmed by now which pushes up the compression as well as fitting high compression pistons. Another issue can be the centrifugal advance mechanism in the dist...

There may be some interesting issues here.

MG7775 comes back from DVLA as an MG car, registered in July 1989.

To my untutored eye there is some strangeness about the entry 'MG 7775' in the
photo of the old-style logbook - it is neither in the same ink or the same hand as
the rest of the entries.
