Radical?

It is just another old gearbox to be loved back to doing the job?

This one is nothing special. Just a tad different is all.

Just not original.......................

The Old Man 262 has done some hard yards but He is not alone in my collection. Most of them have done the yards and survived with some attention and love.

Many Old Blokes and Ladies from all over the world sit on my racks after some love and time and have good humour knowing that they can be USED!

Some of them are Seagulls that mean some milestone for B.S.

A lot of them are not even remotely Seagull.

They all have a unique way of turning a prop but!

Update

Filling with OOO Grease takes awhile........one funnel is 1 hour aye.

New shaft and revised internals as above.

Not exactly genuine but it can be used for my lifetime.

That is a little odd Bruce.
Have you drilled the propshaft bush holes, all the way through?

Do you have blanking plugs for the holes?

A-H, I was thinking just the same thing, must have plugs. I have to say, that's such a clean impeller and housing, you lucky sod, I've had a couple similar but most are a bit of a mess and a lot of work.

It is nice when they unscrew and the threads (L-H) are perfect.

Yes, has plugs.

My impeller is different from above. My end cap was stuffed so new one machined up but not to original.

Quite a bit of modification here and there and a new propshaft was made up.

It should be more robust internally I hope.

A day after filling gearbox as smooth as silk. Left in sun and over night upside down for gloop to fill voids and then a top up with gun later so all good.

Power head........may as well get into that now as interesting.

Con-rod and piston/pin not happy or I am just fussy like my Old Mate Micheal.

A new OS piston pin will sort out the small end and pin to piston problem. not a big deal.

I can adjust the rod big end by hand later as crank everything is cool.

Piston is fine but block is a mismatch when I got the motor as far as piston to bore clearance.

SO

I will send to these guys shortly to bring the bore back to match the piston and my new rings I had made so long ago 50mm x 1/8"

Some pics as we all like pics aye.

It sounds like your trying to put a series 1 or 2 piston (I can't tell which you have, without accurate measurements) into a series 3 cylinder.
Make it idiot proof and someone will make a better idiot.

I have noticed three different piston types on the OA's alone but have no idea which is series 1,2 or 3, they all seem to fit though.

That piston profile looks identical to my OA which is a series 3.

Notice the water pump impellor profile and from what I can see the pinion bearing arrangements are both different. The pinion shaft I am particularly interested in. On mine the pinion bearing is pressed into an aluminium sleeve that is in turn pressed into the box housing. looks like your bearing is pressed directly into the box casting.
