85 K100RT While in the process of replacing a slipping clutch at 60k I decided while into the job to pull the bellhousing to replace the oil seal on the back of the drive dog(commonly known as the alternator drive flange).
Had the clutch housing secured and released the hex nut in the drive dog and pulled the drive dog shaft off of the auxiliary drive shaft. Secured by stiction to rear of the drive dog was a o-ring. Up on the the shaft was the oil seal which did need to be replaced.
With my parts replacement list accumulated went to the web and the micro fiche to secure part numbers for all the parts needed for the entire job. I don't like to place multiple parts orders what with the extra costs of shipping. So I try to be completely ready when I order.
I could not locate the o-ring part number on the micro fiche so I called the dealer I usually order my parts through. They were stumped. 25 minutes on the phone and he talked to two of the mechanics in the shop. Also stumped.
I couldn't believe that in 26 years of k bike wrenching and all the forum discussions on seeping oil from alternator area that it was not noticed that an o-ring was to be between the alternator drive flange and the thrust bushing on the auxiliary drive shaft.
I put off my parts order and decided I'd email some more experienced dealers parts contacts. I referenced the Haynes K100 K75 1373 Owners Workshop Manual which lists the part on the Fig 1.8 diagram, has a picture 33.2b, and in 33-6 describes ensuring the o-ring in place before securing the alternator drive flange.
One week no reply. I took my digital micro calipers and measured the auxiliary drive shaft(14.51 mm). I measured the o-ring at 18 mm outside edge. 14.11 mm inner edge. Thickness 1.80 mm.
Anyone know the part number ?
