Cheap digger or chipper tracks coming off

The other day i put some new tracks (rubber) on my digger and i put some cheap ones (170 per track) on. Today (first use) they came of 4 times in 2 hours and i caught them before they came of a few more times too.
Anyone else find cheap tracks tend to come of alot. I have fairly cheap ones on my chipper and they don't seem as bad as this. The old digger tracks were the original good quality ones which came new with the machine and they came of about 5 times in 3 years.

Re: Cheap digger or chipper tracks coming off

pretty good still, in the manual it says the track should 'hang' around 3 inches from the center bottom of the track frame, im having to really crank the tension up to stop them coming of, they are very tight and they don't hang at all now but i think that will increase sprocket/idler wear over time

Don't leave them slack when they're brand new - they will stretch a bit. Check they're tight each day for the first week, they should be OK after that.

Re: Cheap digger or chipper tracks coming off

Could it be they are not the same dimensions as the old ones, with lower guides. Is it possible to get it onto some dry concrete and track the point of derrail and watch to see where its all going wrong. We,ve got cheaper after market tracks on two of our machines without any problems.

Re: Cheap digger or chipper tracks coming off

well i did think maybe if the tracks are tight its less likely to get grit and stones in there anyway. i was just following the digger manual but i will try to keep them tight and see how it goes. a fair bit of cursing went on today!

I wondered this but the numbers are the same and the dealer was selling them specifically for this model digger so im sure they are the rigt ones. Perhaps they are just stretching at the moment as theyre new, they do seem a bit more flimsy then the originals regardless tho

check the sprock guides are clear of rubber ,on some cheaper brands the rubber dosent let the sprockt push the s h i te out thus forcing the track to ride over & off ,hope that makes sence
