Hub o-rings

Post by bbuice » Tue Feb 12, 2019 9:19 am



I am replacing my rear tire so I am also cleaning and greasing the the hub and wheel. Is there supposed to be an o-ring around the base of the spline I have circled on the picture? There is a groove around the base but my hub did not have an o-ring. Thanks, Benny

I stayed at an Holiday Inn Express last night :shock: So here goes:
I believe if there was an O-ring in that area, it would show on that exploded view.
Now to show how really stupid I am, I don't know what you mean by "hub and wheel" :?:
I thought the only "grease" needed was in the rear end assm. and was drained and refilled at proper intervals
To show my further lack of knowledge, I have never had any reason to take the rear end completely apart :(

Tough to say. On the GL1500, the "spider" that goes into the wheel has the male spline on it with the groove at the base, and yes, an O-ring definitely goes there to retain the grease on the splines.

On the GL1000 it is the opposite, the "spider" has the female spline, and the drive has the male spline with the groove, like you show.

The GL1000 service manual makes NO mention of it, other than it shown in the exploded diagram:

1975 GL1000 Exploded Wheel Assembly
1975 GL1000 Exploded Wheel Assembly

It's not shown in the final drive parts diagram:

1975 GL1000 Final Drive
1975 GL1000 Final Drive

But there IS one shown in the rear wheel parts diagram, matching the exploded diagram from the service manual (above):

1975 GL1000 Rear Wheel
1975 GL1000 Rear Wheel

My suspicion is that the O-ring in that diagram is the one intended to go into that groove...but I can't say for sure, because it's not mentioned in any of the manuals.

The part number for that O-ring is 91359-371-003, it is a 63 mm x 3.0 mm O-ring.

If the diameter of that groove is 63 mm and it is 3.0 mm wide, then my guess is yes, that's where it's intended to go.

My rear wheel is off on the STD for definite reasons (po abuse) and there's no o-ring in the groove. May have to pull the one off the LTD for a cross-check. Curious. :?

Well, I guess there isn't one that goes on the hub spline. I can't find any reference to it anywhere. I have put a new o-ring on the wheel side. Just trying to be sure. Thanks for your thoughts. Benny

Now I’m confused. I also have my rear wheel off and assumed the shown O ring goes on the male spline. Where are you putting one in the “wheel” side ?

There is one that goes in the inside surface of the driven flange and it was there. But it was a little stretched so I replaced it. If you look at the parts breakdown picture you can see a line inside the smooth portion of the flange. That is actually a groove which an o-ring goes into. That's the o-ring number 21.

But I noticed when cleaning up the hub splines a groove that looks like it might be for an o-ring as well. There was no o-ring in that groove and from the drawings it looks like there isn't supposed to be. I was asking about that to be sure about it though.
