Re: 860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Gentlemen, I may have deduced the answer to my question and hoisted on my own petard as a result. The "mystery" piece, now likely identified as #185 in the infamous 860GT parts manual, has an outside diameter that exactly matches the outside of the inner race of the sprocket bearing(s). This would m...

Re: 860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Hi Ducadini, The spacers that go in between the two triangular spaces is established; they each meet perfectly with the flats that the bearings sit against, thus they will properly function. The large spacer (# 190) sits between the brake drum and the swingarm. No spacers of mine have any threaded e...

Re: 860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Thanks again, Craig, # 185 may well be the mystery spacer. Too bad the picture of it in the parts manual is so mediocre; it certainly doesn't show a counterbore, even though it could well be that way. When I disassembled the bike thirty years ago, I kept the pieces loosely grouped by category (engin...

Re: 860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Thanks for the comments, Gentlemen. Craig, I had forgotten the term "counterbore" as I had not used the process or such a piece of hardware for a long time. Vince, I am the original owner of the bike, bought it new, and there were never any wheel swaps. There have been some anomalies elsewhere, such...

Re: 860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Hi Craig, Yeah, I have to agree. I have the two spacers that fit correctly between the two sets of bearings, and the sleeve as it's called in the Haynes, is called a bush in the 860 parts manual (yes, it would be a real nightmare to thread the axle without that sleeve holding the spacer in location)...

Re: 860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Hi Craig, I am sad to say that the pieces do not fit as I had assumed: When I position the headed and stepped spacers in their supposed "would be" position once the bearings are installed on their flats, the headed spacer's "head" protrudes over 1/2 inch from the sprocket carrier, whereas 9:2f in th...

860GT Rear Wheel Drum Brake Spacer Quest for Clarification

Hi All, I know that Steve's sketch of spacer in sprocket carrier is for disc brakes, and since I have a drum, I ask for clarification on a certain spacer. See the three pics at: https://www.flickr.com/photos/[email protected]/albums/72157702723190952 The first pic shows the ringed spacer in the orientat...

Re: 860GT drum brake rear wheel spoke question

Hi again Vince, As usual, I had a brain fade when I was saying" spoke side" and "non-spoke side"; a correctly functional brain would have said "sprocket side" and "non-sprocket side". Thanks again for enlightening me on the spoke insertion alternating pattern per your pic. That helped a lot. I will ...

Re: 860GT drum brake rear wheel spoke question

Good point.

Thinking back, I have never seen spokes touching, even on classic cars with spoked wheels. Hopefully the young bloke learned the error of his ways.
Too bad that it had to be at your expense.

Richard

Re: 860GT drum brake rear wheel spoke question

Ahh; now I get it. That pic helps a bunch. I finally see what you mean about the inside/outside alternation of the spokes. I'll play around with my spokes on the hub, and try to see where 85 degrees works better than 90 degrees; that's still the part I am seeking the answer for. Thanks kindly, Vince...

Re: 860GT drum brake rear wheel spoke question

Sorry Vince,

When you say inside or outside, it does not register; as I said in my original post, I used "spoke side" or "non-spoke side" with the hope of clarification.
I will continue to seek clarification, and I thank you for your interest.
Best Regards,
Richard

860GT drum brake rear wheel spoke question

The rear wheel has 20 of each of two slightly different spokes: 20 at a bend angle of 85 degrees, and 20 at a bend angle of 90 degrees. This is a subtle difference, and I am trying to figure out which angle applies to which side of the wheel (for explanation purposes, say either "sprocket side" or n...

Re: 860GT rear wheel hub mystery piece

Hi Duca,

I'm sorry, but I do not understand your explanation as to the grease and the ring.
Can you please clarify for this old man?
Thanks in advance.

860GT rear wheel hub mystery piece

I know that I am likely missing a previous post, but have looked through the ones here, and do not see a match for my question: Sitting in between the bearings in the wheel hub (not the sprocket hub...) is the piece shown in the link below: https://www.flickr.com/photos/[email protected]/45711138344/in/...
