Bent axle? Not so fast...

[Trikemonk]

This is an update to an earlier post. I recently bought an old 80 Honda 185 that runs great cept for a wobble in third gear or above. I assumed the rear axle was slightly bent but now I am not so sure.
Then I got a 79 or 80 110 that had the exact same condition on the rear. So I removed the wobble tire and rim, center castle nut and removed and looked carefully at the triangled axle wheel mount.
Three pins that key with the shaft and one was missing. I built one pin and installed it and took away the wobble totally. Hope this solves my wobble on my 185 too.
Hopefully this may solve some with axle problems that may think theirs is bent and it may be just this simple. Or is that just how it was done on this early 110?

I removed the plastic shroud/seat assembly on the 110 for repairs and after removing all the dirt and mud from the engine cases I noticed a dual range transmission lever just like an old CT90 I had years ago. Looks like the previous owner never used it as it was hidden under years of mud. And with the shroud on ya pretty much gotta know where to look...Very cool.
Shame Honda did not include a light duty hitch on this one. In low range it would be like a little sport tractor.
And riding it without the plastic shroud with a motorcycle seat with the rear tires all out in the open...talk about riding close to the edge!

So do all Honda rear axles use a similar pin/shaft design? And do all the 90/110's have this dual range transmission?

Getting hooked on threes...Bob

Please show some pictures of what you are referring to. I have several 90/110 atcs' and I'm not quite following you on this.

I am not sure which part ya had trouble with. The axle lost pin deal, or all this time ya had 90/110 atc and never knew they have dual range tranmissions?
Heck, one has to assume most here are riding used machines and not all invested in any books.

By pins, do you mean the "press in wheel studs"? Are you saying that one of your threaded wheel studs was missing and that's what caused your wheel to wobble? That was where you lost me.

from what i got out of it, it sounds like someone put 3 keyways on the axle splines (from striped splines)

pics would be great

all of the atc 90's 110's and 125m's have the dual range gearbox, and i think maybe the 200es big red did too but i cannot be sure.

No, not the wheel studs. Swigin is correct cept four key pins were used and one was missing. The splines did look a bit wore so someone in the past must have cut four channels along the shaft and inserted these small pins. The castle nut with washer holds the pins in place with compression.
Actually, not a bad solution as with all four pins in place it seems to work pretty well.
I was not sure if this was how Honda did it or a field solution done by someone in the past.

That ain't how Honda did it!!! Lets see some pics.

the 200E and ES both had dual range trans. but after that, it was no more.
i do not know if a 185 dual range trans. (shame)

I don't know if I would trust a set up like that with 4 pins and such. Obviously if one or more are lost it creates a dangerous condition. I would look into picking up a nice used rear axle and fixing that right. But it's your safety, not mine.
