Hi,
Most succes on this type of broken bolts I have is with a welder. Just weld a nut onto it. Large nut, a washer below and weld it red hot and point at the bolt. Let it cool down and easy try to loosen it. If it breaks, try again. Never failed here.

Also could anyone help me to understand what is needed with the right pin, or what is needed to get the axle back on

Hi,
Once had this issue on a John Deere from the 1980's.
Imho putting the tombstone under a milling machine or a big bench dril and make the hol round again. Turn a fitting bush on the lathe and press in. Secure with loctite and you should be good to go for another 60 years.
Most available 2nd hand tombstones won't be much bitter, may be a little better.

Sorry for all the pics, but does this look like a major clutch, the clutch plate is 12" diameter

Hi,
This looks on the photo's like the origial Fordson Major setup. But then it should be an 11" clutch. There was a heavy duty 11" clutch as well on early tractors with a more "black" appearance of the friction material and thicker lining. Then you should have found spacers between the flywheel and the clutch cover.
The 13" clutch is fitted with 8 bolts to a different flywheel, so this certainly is not the later style 13" clutch type.
Can't find any info on a 12" clutch disc in a single clutch. I think I would replace the complete clutch with a new 11" or tried with a new 11" disc first and setting up the old clutch cover. But that usually isnt a really long lasting thing when you intend to use your tractor where it was built for.

Thanks Emiel, from what I was reading, it looks like the 11" clutch can take more abuse, and was better suited to 6 cylinder conversions like mine,

Hi,
The 11" is the basic clutch, which acutally is allready quite strong. Back in the day a heavy duty 11" was available, which was later replaced by the 13" really heavy duty applications.
THe dual 12" live drive clutch is a littlebit sensitive to abuse, although it still is a quite sturdy design. these days a improved version of 21st century design is available as a afmtermarket unit. This would be my choiche with a 6 cilinder live drive if the old one failed.
Are you planning to use all horses in your 6 cilinder? Or will it be a fun tractor? In the latter case any clutch will hold out.

yeah I'm going to just use it for fun, maybe even a 3 ton tipper trailer with some firewood, the man I bought if off used it for work, he said that the tractor broke his 8' mower in a hay crop, it was on a dyno machine about 10 years ago, it had 132hp at the shaft, I believe it still has all of those

Emiel, is the aftermarket livedrive clutch to go for a 6cil? I should check mine, because the pto isn't disgaging.

Hi,
No personal experience but is said to be strong enough for a 6 cyl. And tractor pulling. Google for kawe super major koppeling.

Here's a update if any one is interested, got the clutch changed and got the tractor back together, it was a standard 12 major clutch plate, but it seems all was not as it seems as I spoke to a man who converted 100s of these tractors to 6 cylinder, seems like the flywheel on the engine is not original to the thrader engine, so I had to reuse the pressure plate, also I took off the crankshaft pulley as it is badly rotten with rust and is badly warped so it was cutting into the timing case, trying to find a pulley now is impossible it seems so I'm at a standstill really till I find a replacement

Sorry for the long delay, but here is a update,
Had to buy a new injector pump as I got my old unit tested along with the injectors.
It was badly corroded and uneconomical to recondition it, so after a long search on Google, I managed to find a reconditioned pump to replace it, just waiting on my injectors now

Also I came across a second hand holset hx35 turbo with all pipework and both manifolds, what are your thoughts on putting a turbo on this old thames thrader engine,
