My poor old jcb

[Self builder]

Just to say hi to everyone on the forum. I have used the forum several times when trying to fix my poor old jcb 801.4 (1996). I have been building my house for several years now and the old jcb has been great. I have repaired it many times, usually just blown hoses. A few days ago it threw one of the tracks and I've been trying to get it back on for a few days now. The problem is that the track adjusting screw is rusted solid. I've tried just about everything I can think of....heat, oil, big spanner....all to no avail. If anyone has any ideas I would be most grateful......thanks a lot.

More heat & bigger spanner… get some bulldog dbx soaking into it as well..

More heat. If you're trying to use a blowtorch it won't be enough.

Thanks for your reply. I used a plumbers torch, do I need an oxygen acetylene burner ? And what is dbx? Thanks DAVID BUT.

Thanks for your reply. Looks like I need an oxygen acetylene burner.

Unfortunately I don't have any big equipment. I think you guys are out of my league.

Ok working on the theory the track came off and you are refitting the same track, get yourself a ratchet strap, place the track that’s off on the driven sprocket end, place the other end in a place where it would be against the idler end, using the ratchet strap put it around the top half of both tracks across the frame, put a bit of tension on the ratchet strap, drive forward on both tracks at the same time!

I'm at the Crescent off London Road.
The nut is difficult to get at/loosen, see pictures.

Now that's a good idea !! I never thought of that, but will give it a go when the rain stops.
Thanks a lot, much appreciated.
