How to avoid driving gear problems....

[Christoffer Ahlfors]

Thank you John!
That instruction clears the fog in the kit instructions. I have never accepted that it be essential that the bushing can move freely on the shaft. This is the proof! It is the sprocket that moves on the bushing when tightening!

To answer your question, I use grease on the KT and Tigers hub caps

This must be an error in translation. There is no way you could possibly fit the hub caps with grease (Schmierfett)! Neither can you use the cone headed bolt. The hole in the shaft is now occupied! I wonder how you mean, Peter?

This might help fitting the taper locks correctly. Pop this into your web browser. It will also show you the correct torque settings for tightening up the grub screws. I should add if the key fills the key way head to toe there is a fair chance you could crack the taper lock when you tighten up.

Thanks Richard
That's a much better way to get to the PDF.
I haven't got round to checking the key and key way dimensions yet on the Chieftain. But as long as there's a little head room gap on the key it'll be fine.
I don't think the diagram on the PDF shows the tiny gap very well so I found this picture and snipped it. Although it explains removal of the taper bush, it also shows the gap and explains what could happen if no tiny gap is allowed.
Taper bushes are fantastic simple and often over looked device and are very effect when used correctly.
Hope this helps.

I'm still wondering as well what is retaining the hubcaps?

The fitt of the hub caps is very tight. Thus a thin layer of grease (yes Schmierfett, no translation error!), is enough to keep them in place. The fitt is so strong, that you need a pair of pliers to pull them out! No screws are needed.

As you can see, the hub caps and the insert into the driving wheel are quite long, thus it´s no problem to do, as I described. There is no connection between the cap and the axle!!

[Peter Quambusch]

As promised, here is my solution for the JT:

Take a self securing 5 mm nut to fix the cone head and another one, which slightly protudes over the cap.

Take a bevelled washer...

...and place it upside down on the nut.

Finally, screw the assembly into the axle. Done. key and taper lock secured.
