1100 Final drive

[hank]

Popped over here from the 1150r section to ask advice on behalf of a mate.

A mate of mine took his 1999 1100rs to the dealer for a service, while doing the job the mechanic discovered a roughness when rotating the rear wheel. My mate was told about this when he went to collect the bike. The mechanic told him it needs a new bearing, so my mate left the bike with them for the work to be done. He later received a call from the mechanic to ask, "Would you like to pop over (60 mile round trip) to the shop and have a look at the crown wheel and pinion, they are scored and need replacing". The bike has done 45,000 miles and is never thrashed or abused, should he just get them to replace the bearings or bite the bullet and have the crown wheel and pinion replaced as well? Quote for the bearing work is £350, they never quoted for the additional work and parts needed to replace the crown wheel and pinion. My thinking is that a crown wheel and pinion will score through use anyway and shouldn't need replacing after 45,000 miles. The same dealer replaced bearings in the final drive on this bike at about 30,000 miles.

Also wondering if it's worth replcing it with a complete second hand unit from Sherlocks or Motorworks.
Any advice on this much appreciated as a trip to Germany is planned for next week.

My mate says he is about ready to swap the Beemer for an MZ.

My guess is yes he does need it. Lost mine yesterday.
