HP85 tape drive capstan



#2

I have an HP85 with the usual disintegration of the rubber tire on the tape drive capstan. I believe it no longer has the original outside diameter due to multiple cleanings. The drives works but is noisy at high speed and occasionally unthreads the tape in the cartridge (rewinds past the beginning of the tape).

Can anyone tell me the original OD (and possibly the ID so I don't have to take it all apart before I find a replacement)?

I plan to use the rubber tubing trick or possibly a VCR replacement tire for the repair.

Any other suggestions gratefully received.
