I just finished renovating the oil/water pump on my 87 K100RS 12/2011
I used K-freaks compiled tech articles as an instructional guide.
There are some part number changes that have come into play since Jan 2002.

Service announcement from BMW
"All K75, K100 and K1100 now share the same slip-ring seal, spacer and impeller as the K1200 RS/LT"
Metal impeller 11 41 1 461 173 ($14.26)
Spacer 11 51 1 464 902 ($7.65)
Slip ring 11 51 1 704 084 ($24.54)
The 'O' rings:
11 41 1 460 328 ($1.02)&
11 11 1 460 392 ($1.69)
And Shaft Seal
11 41 1 460 329 ($10.42)
are also needed.
Prices from MaxBMW as of 12/2011
These seemed to go together quite well and aside from me being a little squeamish about driving a screw-driver into the housing to release the original seals not very heart wrenching.
Cheers, M
