I just replaced the alternator in my 2000 DII. It turns out that the only problem with the old one is a wrung out drive pulley. Can someone help me identify and/or purchase the correct pulley? This is a "solid" one, not the limited slip found on newer ones, though I suppose either would work. Many thanks in advance.

This is what I have for alternator bearings on my Disco parts cheat sheet...
- D/E Bearing #1120905510, #BRG6661, #B17-99LLU $8.16
- S/R/E Bearing #1120905525, #BRG62032RS, #6203 $2.24 (The smaller 6203 bearing in 2RS format (2-sided Rubber Seals) is same bearing in 70mm serpentine belt pulley and belt tensioner pulley. NTN & SKF are two good brands.)


I don't know how legit these part numbers are so do some research before buying.

pdogg; The pulley is supposed to mount to the shaft which runs the length of the alternator and is about 1/2" in diameter. The hole in the bad pulley is now essentially the diameter of the inside of the pulley, or better than 1". When you shop for pulleys now, you find that the newer ones, at least some of them, have something which probably should be called a viscous coupling (I think) which allows them to slip when first engaged then tighten up and run at normal RPM's. This pulley does not slip. It is solid.
JUKE179r; I'm not looking for bearings, but thanks.
