Hi there

New member from not-very-snowy Denmark.

Our club just got its first grooming machine, a used PB 200 from ca. 1987, bought from an Austrian resort.

The tracks are aluminium, and quite loose. Is it possibly to adjust the track tension on this type of machine? How?

Kind regards

Mads Bondo Dydensborg

P.S. Sorry if this is a trivial question - we are very much beginners here :)

Hi Madsdyd,

To adjust the track tension you turn the both track tensioners located on the front axel, one at each track. If you look through the track between the front tire and the tub/frame of the snowcat you will see a large nut that should have a forked looking locking tab keeping the tensioner from turning. Remove the retaining fork by unbolting it and then you can reach in with the right sized socket on a long extension and turn the adjusting nut.

The PB200D is a tough snowcat that will last a long time but maintenance and adjustment are real important like on any piece of equipment. I recommend you get a hold of Pisten Bully and get a maintenance manual if you don't have one already.

In the manual it says that if you lift the track from the middle it should raise between 40-50 CM also it will look abit loose after you tighten it but after you drive it around abit it will be perfect Also count how many threads there are on each adjusterbolt and match each side so that they are equal,enjoy your 200.I also suggest you get an operators manual as well as the service book. hope that helps, Payton

Pisten Bully also has an Electronics troubleshooting manual and a hyraulics troubleshooting manual that are worth their weight in gold. Get them!!! you will be so glad you did.

Thanks a lot for the info!

I have contacted Kässbohrer (through the contact form on Pistenbully.com) to try to obtain the manuals - thanks a lot for pointing this out.

Would be great if the manuals were available online, but I guess copyright rules this out.

Kind regards & happy holidays from Denmark!

Mads

For the old style PB200 if you kneel at the front of a track and look between the grousers to the inside of the front idler wheel you will see a 19mm bolt holding a formed metal keeper over the track adjusting bolt which I think is either 41 or 48mm.
For the PB240/260/280 if you kneel down and look between the front and second idlers you will see a 24mm hex head protruding from the side of the frame. The PB wheel nut (lug nut for you) tool will fit this although I prefer to use a 3/4” drive socket and ratchet.
I can’t recall for sure but I think the 220 still had the old style adjuster even though the 220 was produced at the time of the 280.

Thanks for that info, I mistyped earlier, I should say that I know how to tension the tracks, I just do not know the correct tension. My understanding is that they should have just enough tension, so that the sprocket doesn't jump?

If I recall correctly “Track tension is correct when the upper section of the track can be lifted approx. 40 to 50mm midway along its run.” (this is roughly 1.5 to 2 inches for the metricly challenged)

(the above is somewhat subjective as each of us has different muscle strength)

Once again trusting my sometimes faithful recollection, “Correct track tension allows some track jumping when performing extreme turning manoeuvres.”

The quotation marks indicate where I believe I am quoting from PB publications but age and time are not on my side.

If you tighten the track so much that it does not jump at all you will cause undue wear and tear on track components. :myopinon:

Operators should seek to minimise turning operations e.g. for repetitive dozing jobs go back and forth rather than turning around at each end
