Frame number is a M20/M21. The number by the pushrod? tunnel is the date of manufacture of the engine. If the correct engine is fitted it would be a 500cc or 600cc side valve

Somewhere there is a rocker box that I modified. A couple of holes were cut in the box top and tapped aluminium bushes welded in place. The pushrods could then be eased into place and after the rockerbox has been bolted down, plugs screwed into the bushes. I think I used 25mm conduit thread.

My engine has just been assembled with a new ABSAF high volume oil pump. Made out of real aluminium instead of monkey metal

I have just rebuilt my B31 engine.
After filling the oil tank I loosened the oil feed pipe at the engine until new clean oil dripped out and re tightened. I then removed the ball valve in the timing cover and kicked it over a few times until oil flowed from the hole and then replaced the ball valve.
This ensured I had oil all the way from the tank to the end of the crank.

Thanks Andy, I'm a couple of hours away in North Yorkshire so postal costs will need to be considered. I've just bought a new big end so it wouldn't matter if I got a shaft with a knackered big end. Let me check prices and costs.
Talk about bad timing, last week I was working in York

The Ariel hubs are lighter than the BSA full width hubs, better looking and have a superior adjustment method

Lightweights / Re: BSA Beagle Rocker Feed

For oil mist lubrication to work the oil mist has to reach the part requiring lubrication. If the beagle engine breather was on the rocker covers, then oil would be carried to the rockers. As it is the oil mist is required to be forced into a dead end, it just won't happen

I have just measured a spare B31 crank, it is 3/4 x 20
Coldbrew, if you would like this crank I am open to offers (My B31 has a Pearson crank)

Twins / Re: BSA A10 twin leading shoe brake
« on: 03 February, 2017, 21:44:40 »
Sorry TTJohn, size for size a twin leading shoe brake will always be more powerful than a single leading shoe. If you have found the reverse then the twin leading shoe brake was either not set up properly or it was damaged.

The aluminium cylinder with the damaged chrome can be repaired better than new. There are many places that will replate them with harder wearing Nikasil

22TPI is nowhere near 1mm.
1mm translates to 25.4TPI which is close to 26TPI
