Show us your Arb Diggers please.

i thought it was stones and sticks getting inbetween the tracks that knocked them off. I now just pump some grease in to keep them tight if i have been doing any distance tracking.

Just a thought, but how about getting the Idlers fitted with the rim of a sprocket to help keep a grip either end?

Sprockets are cheap enough, and not a big job for a decent fabricator?

 

You could fit guides, but it would need to be something sacrificial like nylon blocks to prevent them damaging the track.

Eddie our fitter suggested doing this on a machine that was easy to de track, have you actually seen it done?

 

The alternative suggestion is to add a longer axle to the roller nearest the idler with outrigger idlers.

thanks Eddie, its happened twice in 14 months so not something i am tooconcerned about tbh.

Do you tension them as per the spec in the manual?, it makes a big difference!

[Matthew Storrs]

I find tensioning tracks too much can have the opposite effect, there is meant to be a bit of give in a track to allow it to contort and flex as necessary, I think just tension it up as your meant to and just be cautious going over the rough stuff, like Stephen I have only had track come off twice in over a year- both times in the most awkward situation ever!

[Breezeblock]

i find that the edge of the rim on the idler is sometimes worn and this can allow the track to ride of easily phone cat and get the wear spec for the idler

I've not seen it done afterwards, but there is machine I've seen with this as standard and it won't come to me? I have an old 3 tonne JCB in my mind?

 

 

I'll ask John Craig his thoughts on this subject, as if anyone will know how to best prevent it he will.

Again the chaps at A&B services have been converting diggers for forestry work for 30 odd years. There's quite a few mods they do to strengthen undercarriage and lessen track throwing.

No I've never seen the manual for my machine!

I jack it up, if it looks like it shouldn't depending on where I'm working, something inside my head says to give it a bit of a pump of grease or not.
