Re: WANTED - 1949 MM Quarterlight Rubbers

Maybe a later one and some Sugru stuff? I've never tried it but am told it is quite good.

Re: WANTED - 1949 MM Quarterlight Rubbers

You know what happened to the last surviving pair, don't you? Chances of finding any more are soooooo tiny. Might be a case of waiting for Frank to get them reproduced.

Re: Water pump fan blades.

I once went to fix an MGB. Owner had fitted a fan that pushed instead of pulled. Sure you haven't got the same?

Re: Water pump fan blades.

Only had single bladeson mine. Sure you've not got a bu66ered thermostat in there? Also, is the bottom metal casting blocked?

Well done to Will for organising the new valves to be custom made. Just collected them from the Post Office today so might get a chance to fit them. Averaging 55 hours overtime per week so not much spare time. Phew!

Re: MM Quarterlight Repair

I can't see any specific reason for either direction unless it interferes with the rubber profile??

Re: Tappet screws

USHM valve stems are 7mm but it is possible to use a reamer to open out the guides to 5/16 and use BMC valves. Plenty of options. I make valve guides from scratch so can stick in almost any sized valves with larger heads and larger stems. Possible that someone has done the same to yours. Seem to rec...

Conversion bits

I may need to run my Series MM on an A-series engine for a while. It is a 1953 and therefore already has the structural changes built in to change between engines. What I'm going to need is a gearbox tunnel cover, a gearbox crossmember, some engine mount towers and the clutch mechanism that goes bet...

Re: holes for semaphores

Chassis number 260431 seems to be about the last one dispatched with cover plates over the trafficator holes, as far as I can tell with Travs running on until circa 428264. not sure how accurate this info is.

Re: freeing seized studs

Not all blocks used metric for the exhaust. I have 2 here with (IIRC) 5/16 bsf which I only discovered when I removed them. At first I thought my thread gauge was wrong. Had lots of fun making new brass manifold nuts.
Same issue with some of the gearboxes using non-metric bits.

Re: Quick n dirty comp ratio calc

Thaks, Phil. Works out at 7.3 comp ratio.

It's for the late 53 Series MM which I'm using as my main transport. This one would take an A-series without mods, other than bolt-on stuff. 27bhp isn't really enough for everyday transport round here.

Quick n dirty comp ratio calc

Can anyone with the figures to hand give me a quick calc for a 948 with a 12G295 head on it? Just a guide figure would be enough. Need to see if it would be a viable project to fit the Shorrocks to this engine. I couldn't find a suggested figure for the area above the piston inside the bore to use i...

Re: Torsion bar - how slack is slack?

The torsion bar remains under torsion even at full rebound (hence difficulty in removing trunnions) so there isn't any noticeable slop.

Re: Torsion bar - how slack is slack?

Mine moves quite a bit. Not a worry for me since both sections still had lots of teeth left on the spline and no signs of distress.
