Starter motor rebuild

[mgv8]

I have a Lucas starter motor that goes click but not turning motor over. Small hit with a hammer and it works.
The question is, how hard is it to rebuild my self?

It's in bits and got new brushes and bushes on the way.
Needed a good clean but overall looks OK. The only thing I need to work out is how to compress the spring at the cog end so I can get to the bush that end?

Thanks, that is what I need (or need to make).

I found a spring clamp that had been put under tattoo kit on ebay so was cheap. Now have that off. Next problem is the part the spins will not come off. It looks like there is a collar at the bottom that should turn and line up with the slots in the shaft. But can not work out to get to it or turn in?

There is at the bottom of the drive pinion a washer that had slots in it. These slots need to line up with the slots in the main sharft. This can be done with a screw driver. Lines up and slides out.
