Bobcat T 190 undercarriage

I have a Bobcat T 190. How do I know when my undercarriage parts are worn down? What are the recommended hours for replacing them?

When the parts start to fall off and make horrible grinding noises. Tracks can be done at 1000 hours or near to that point.

Are there any other factors beforehand? Having the track fall off seems like the last thing I want to happen.

Wiggle the idlers around, lots of slop is a sign, rollers leaking and split and excessive sprocket wear are all signs.

May seem silly to some but I dont have much experience in tracked machines. When a dealer or private seller says the machine has say "65% undercarriage" What are they really reffering to? Whats a good numer/percentage to consider when buying a used machine?

My guess is they are referring to the track remaining and they think that you have to replace the tracks and the entire roller/sprocket/idler package at the same time.

I have been reading up and it seems as if your undercarriage will last longer if you replace everything at the same time. This seems expensive, but I would like to get the highest amount of hours I can out of my machine

That propaganda was written by dealerships making money on you, you can get 2000 hours on an undercarriage on a CTL and only replace tracks every 1000 hours, after the 2000 hour mark, the sprockets need to be changed and rollers can be checked for slop and same with idlers, these 10,000 pound and under class machines don't see the harsh weight loading and extreme conditions that bulldozer might see.
On a bulldozer you can get 3000 hours out of a set of rails (track links) and keep the track pads, so you are only replacing the sprockets and rails and swapping out the pads. Rollers are much cheaper to buy as they need replacing.
If I had to "rebuild" my Takeuchi undercarriage every time I replaced the tracks, I would be dishing out close to $600 per roller ($2400+ in total) and $800 per idler ($3200+) so I would waste $5600 in parts that can be replaced as they wear out over time.

Ya, I have thought about that. But I all of the articles I have been reading and research says that the parts should wear together and that I should at least change my sprocket with my tracks. They say that the machine won't run well with unequaled worn parts.Thanks for the info, just trying to make the most educated decision.

My t300 had about 1000 hours on it when I changed tracks only, and now im at 1150 and the sprockets and tracks are wearing great. If the sprockets look good then run them.
