M750 rear bump stop missing ??

I wouldn't consider it to be a DIY job.

Does it have a remote reservoir? If so, it'll contain pressurised nitrogen, so won't be home serviceable.

If it's just a basic shock with no reservoir, then you'll still have to completely strip it to get access to the end of the damper rod so that you can slip the new bump stop on. That will require a spring compressor then you'll have to remove the shock body cap to expose the circlip that holds the whole thing together. Even after all that, you'd still need to know the correct amount and grade of oil to refill it with.

If the shock is of an age that the bump stop has perished, then it's probably passed its best too. Time for a replacement perhaps?

Some places can refresh them, but I wouldn't think a stock Sachs was worth the effort.

Brook Suspension offer that service for £130 plus £18 for a bump stop https://www.brooksuspension.co.uk/sa...epair-service/

Actually, even if it hasn't got a separate reservoir, it may still contain gas. I've just been looking at the old Sachs shock from my Evo to see how easy it would be to strip and it has a sticker on the body warning that it contains 'pressurised gas'. (Yours may be the same). There's no external valve on this shock though so, even if you could successfully dismantle it, I can't see how you could recharge it with gas. (Presumably, the shock rebuild companies drill the body and insert a valve to facilitate recharging.)

So Mr Gazza's method is probably your only option if you don't want to replace the shock itself. (You would probably still need a spring compressor to get access to the damper rod.)
