On a bike that age the spacer may also be worn, that the seal runs on.

Always a good idea to change the seal and spacer together

The spacer can corrode, and damage the seal and cause it to leak - it will then also damage the new seal if the spacer isn't changed

Try a new spacer, if it still leaks, then your new seal may be damaged and you'll need another one

The spacer should be removed and cleaned. There is an O-ring which seals between the spacer and the shaft. Replace that o-ring so that the leak does not occur between the shaft and the collar. The spacer has an internal bevel edge for the o-ring. do not put the spacer in backwards. This is covered in the service manual under transmission.

One other caution when installing this seal is to avoid inserting it too deeply. It should be "just short" of flush with the case, standing out about 0.5 to no more than 1.0mm from the mouth of the socket, and, of course, it needs to be square with the case. Running this seal in too deeply can cause the seal lip to overhang the notches in the shaft collar, leading to a really big leak.

Remember that the output shaft seal holds oil under pressure.

Bearing replacement requires the crankcases to be split, so yes it just about a big a job as it gets

You can get the part no.s of the bits off the RonAyers website

Chain should never be tight
If bike has been used with the chain 'tight' then yes your output shaft bearing may be knackered
