Speedometer Drive Gear

[GreenValk]

Hello Valkyrie Experts,

I have a simple question regarding the speedometer gear drive.  I've changed the front tire several times and thought after torquing the axle there was still a little movement (rotation) in the gear drive housing. And the purpose of the tang on the housing and the boss on the fork was to keep it from over rotating.  This last time I install the front tire, once I tightened up the axle there was no movement (rotation) of the housing. I pulled it out today and (for lack of better terms) the "spacer" is secure with the "housing".  Is this the way it normally is?

Thanks,
Steve

The spacer is on the right side and the gear housing on the left. What you describe is not clear

The parts diagram shows proper assembly: https://www.partzilla.com/catalog/honda/motorcycle/1998/gl1500ct-a-valkyrie-tourer/front-wheel

I was hoping to be clear enough without pictures, but it didn't work. Yes there is a spacer on the right side, but I am just asking about the left side. Does the cylinder on the inside of the speedometer gear housing rotate separate from the housing? I will try to add a picture.

Part #11 in that diagram rotates with the wheel, turning the gear inside the un-numbered housing, which should not rotate, because the cable attaches to it.

[GreenValk]

Part #11 rotate and spins the inner cable for the speedo. You can't see from the parts diagram but inside the housing is a cylinder that the axle goes through. That is the "spacer" I'm asking about marked in red if this picture works.

[WintrSol]

That spacer is part of the housing, so is not shown as separate. It applies the force from the axle to the axle bolt, binding the bearings, inner collar #6 and outer collar #5 into a single assembly

Thanks for hanging in there with me. I understand completely your description of the front axle assembly. I just thought, after everything was tightened up, I remembered the housing having a little bit a movement (rotation). As you said the cable holds the housing in place so it can't spin freely around, but I thought it had a little movement to keep the speedo cable properly aligned as the shocks  absorb any bumps in the road.  I just want to make sure the spacer hasn't mushroomed and caused it to bind up within the housing.

It's not the cable that keeps the housing from turning/spinning, it's that tang/boss combo you reffered to in your original post that keeps it stationary. And I've never had a housing move once the axle is torqued in place.

[WintrSol]

The cable should curve in a way that it easily flexes with the axle movement, so doesn't need the housing to move at all.

Isn't there a couple of tabs to stop the housing from rotating (or more accurately braced against the tab)?

As for pictures, go to postimage.org , and set up a free account. It's fairly easy. UL a picture, click share icon, 2nd link from the bottom, and copy into your post.

Yes, if you look at the second photo on page 13-14 of the fsm, it shows the lug, which is cast into the housing, engaged with the stopper, cast into the fork. The lug on the housing should be mounted behind the stopper, so the housing can't rotate in the forward direction, in case the pressure on the housing from the axle doesn't hold it.

I know what you are trying to say GreenValk, I just put the front wheel back on my Interstate and I questioned the same thing, the outer housing on the speedo assembly is tight, it does not rotate a little bit between the lug and the cable. This is the first time I did the IS, previously I did my 97 Standard and I thought there was play on that one but the speedo assembly on the IS is different than the Standard so I assumed that is why, now you have me wondering again until I check the Standard which is at the barn right now.

Actually, the speedometer drive gear is the same on the Std/Tourer and the IS. The IS has an electronic module attached to it to drive the digital speedometer.

All very helpful. Thank you very much for the input. I'm convinced that I was previously wrong and the interior spacer and housing is manufactured as a single part and thus the housing does not rotate even the slightest once the axles is tightened.

You are right about that.  On one of my many front tire changes, I goofed and put the notch of the speedo housing on the wrong side of the wheel notch.  It stayed there till I replace the tire.  Didn't move a bit.
