Re: The new Project

One of my posts on page 2 of this account talks about the fitting of the swinging arm bearings. Having made the top hat bushes and worked out how to fit the bearings I was able to fit the swinging arm temporarily to the engine plates. With the gearbox in place, that enabled me to work out the chain ...

Re: GEARBOX BUSH

Yes and yes!

I have done this several times now, without any subsequent problems (so far).

Re: The new Project

IMG_81014.jpg Exhausts were a problem. Although the originals came with the bike, they were all damaged in the fire. The pair on the right side had got so hot in the fire that the silencers had gone oval instead of round. On the left side, each pipe had a big dint close to the cylinder head. My gue...

Re: The new Project

One headache was the rear brake cable where it connected to the brake pedal. Part of the original cable remained attached to the rear brake pedal and this demonstrated that the only way to make it would have been to run the cable inner through the bracket which retains the cable outer before solderi...

Re: The new Project

The original petrol tank was reduced to blobs of aluminium stuck between the fins of the cylinder head in the fire. After various problems with getting a new one made, I bought the one which had been a prototype, as per the first photo. IMG_1064.JPG You will note a strip of wood glued to the undersi...

Re: The new Project

Today, for a change, I decided to put up some photos of the original carb. From the first one, seen below the carb looks quite restorable: IMG_81071.JPG If you look at yesterday's top photo, you can just about see the union onto the (new) carb for the petrol pipe. The union is the original and has n...

Re: Wanted: clutch centre (lost mine)

Sorry John, but I can't supply a used 2 plate clutch centre. I do have a new old stock 2 plate centre though, without the studs (unless I can find a set). If that is any use to you, perhaps we could meet up in a supermarket car park somewhere in Herefordshire?

Re: Sq4 MKI blown head gasket

The solid copper head gaskets were used successfully by the Healey brothers to cure problems on at least some Mk I Square Fours. The Otto gaskets, being made of modern materials, do a better job but it all boils down to getting the torques on the head bolts enough to seal the gaskets but not enough ...

Re: The new Project

I have fitted a Bennet Longman design alternator which I made myself. Partly this was out of the interest in doing it, partly because the engine plates on the Healey would conflict with the longitudinal studs in their usual position and partly because I thought it would be cheaper. My advice to anyo...
