First test drive with problems

[Volker Pfisterer]

Hello
May be somebody can help me.
I have big problems with the tracks of the M16 Halftrack.
First the sprocket do not fit accurately , sometimes the cog hit the rollers
of the chain.




Second, the bolts of the chain destroy the boogie wheels, idler and sprocket.
First of all the chain lock.
The pictures where made after the first testdrive of some minutes, the idler wheels
have a lot of abrasion and i think the thin aluminium will have a short live.
The abrasion is not only color it is a lot of aluminium too.




I checked the track to be in line with all wheels and all "wheels" it self.
But that doesn t matter because the track hits sometimes the inner or outer side.
Sometimes the bolts hook a pocket of the idler wheel and blocked.....
The drive is very jerky.
I tried to tighten the tracks more or less , no change.

What can i do?

-Grinding all the bolts and may be loosen them
- sprocket , no idea

Hi Volker

The roller chain and the drive sprocket that we use for the US half track is commercially manufactured. These parts are made by the million and used industrially all over the world. It is therefore, very unlikely that your sprocket and chain do not match perfectly. On our demonstrator model we ground down the both ends of the pins on the closing link so as to avoid the type erosion you have suffered. You will find that this makes a vast difference. It is also true that when first run, this combination steel chain and rubber tread type track is quite stiff. This stiffness soon disappears after a short period of running.

Hi Mark
Thank you for the answer.
Do you ground down only the pins from the closing link or all pins?
I think all the pins have very sharp ends ,how deep i can grind them?
Can you show me a picture?
When this problem will fixed i think i can run in the tracks.

Hi Volker

You only need to do the pins on the closing link. All the other pins are shorter and clear all the running gear. Grind as much as you can without losing the groove for the retaining clip.
