I first tried to replace the key.
As I live in Belgium they have no stock of imperial keys only metric, so
I bought a 5 x 5mm oversized and filed until it fitted on the crankshaft.
Stange,it did not fit on the flywheel, so I filed half of the key to fit the flywheel.
Strange that it is not a square size.
The key fits now in both, but is asymmetric.

The engine doesn’t make a knocking noise anymore on a first test.
As it rains today I hope to cut the grass tomorrow, let’s hope it stays ok.
I will let you know in a few days if everything is working.
Thank you very much for your help.

Thanks yes you seem to have identified it , better pic attatched, any idea where I might get one and what is the adjustment necessary if any.
Also two bolts have come loose and lost the nuts, they go through the rocker arm, any idea of their spec as metric is my game and these are obviously imperial, and again any idea where I might get another couple of bolts and nuts, or maybe just nuts.
thanks.

Down in Cornwall we also try to get any small tractor and walk behind machine into the ring with the ring master giving a short description of the machine and owner.

Five different manuals and not one of them mentions any torque figures anywhere,
If you are not confident in just pinching them up I would guess that 12 foot pounds for clean dry threads will be safe but as the studs /bolts go into an iron block you can possibly go to 16 without fear of doing damage.
Just remember that if you lubricate the threads you should reduce the torque figures; some reference material will say by as much as 30%.

[vhgmcbuddy]

No worries.
Are you allowed to advertise them on here?

Couldn’t agree more. I came to the same conclusion when visiting Newby Hall. My favourite show of the year is The Festival Of The Plough at High Burnham, Lincolnshire. Certainly does not have the number of exhibits that the mainstream shows have, but a large proportion of what is on display is actually running.
There’s nothing like the smell of two stroke exhaust first thing in the morning!!!

Your BSA has a tapered crank, no key.
Everything else is covered in my previous detailed post.
Get a new 3/16″ (decimal 1875″) square key and go from there.

More info on the tractor from Jr.

It’s a cat 3406b from a foden 4000 truck, 14.6 litre and is currently running about 500bhp with uprated fuel pump and injectors. When the turbo blows it’ll be replaced with a much bigger one from the states as the engine is very popular over there in truck of the 90’s and are regularly tuned to 7-800 bhp for normal use and can see over 1000bhp with uprated internals!!

I removed the engine from te mower, and took some pictures.

The key seems to fit on the flywheel but not on the engine’s output shaft.
You can easily move it, it seems to small.
Is it a wrong key?

I have a spare Marquis but with a BSA engine, I could take that key if it fits.

“picture 1”: the keyway on the engine’s output shaft.
It doesn’t seem damaged to me.

“picture 2”: the key in the flywheel.

“picture 3”: the key with its sizes. 4,4mm x 4,4mm x 44,3mm,
if you look closely you’ll see it has a bit of damage of the screw

“picture 4”: the key on the engine’s output shaft.
It doesn’t fit for 100%, it is a little loose, easy to move.

“picture 5”: the flywheel cleaned.

Thank you,
