There is something obstructing the reduction to be fitted to the rear axle. You must not use the bolts to get the reduction to get in contact with the rear axle. I can see in a couple of pictures you have provided, that the brake drum was I a very bad shape. Have you done anything as to get rid of the rust and make the brake drum smooth and level? A brake drum like the one in the picture needs to be rotary-cut. There is a big possibility that the brake bands are jamming against the deteriorated brake drum.

Hi ollek,
Thanks for your help. Yes I have cleaned the rust and dirt from the inside of the brake drum. In the end using the bolts to pull it inwards worked quite well. I mentioned that I did try that approach and I was NOT happy with it and it was getting too tight on the bolts so I stopped and tried another idea. In the end it was using the bolts that did the job and all with very little leverage on the short spanner. It was so light that it was just above being able to use your fingers to do them up. Anyway all is back together with all new seals and gaskets and new SAE140 oil in the reduction box and new oil in the gearbox with no water in the mix.
Now it is time to start preparation for paint work. this will take some time but I'm not in a hurry.
Thank you once again to all help offered on this tricky fix.
