This is the aftermarket rear idler for the Bobcat® T870 track loader. This is the larger roller at the rear of the undercarriage directly below the sprocket. This idler fits on the original serial breaks in the A3P, AN8, ATF, B3B, ASW serial ranges but after the B47 serial break this idler is no longer an option.


Always check your rear idler for wear when you change your rubber tracks and sprockets. If your idlers are worn there is a good chance the tracks can come off during operation causing significant damage to the track.


The T870 rear idler is much heavier duty than previous generations of Bobcat track loaders. It is not interchangeable with the smaller models made prior to the T870.
Please verify that you have the solid mount undercarriage system as the suspension system may require an alternate part number.

This idler fits the following serial breaks:

  • A3PG11001 & Above
  • A3PH11001 & Above
  • AN8L11001 & Above
  • ATF811001 & Above

Alternate Part Numbers

  • Bobcat Dealer Part Number: 6698049

Optional Part Availability

There are no known alternate part listings. This idler is guaranteed to fit the serial numbers specified. After serial numbers starting with B47 this idler no longer fits so you must verify your serial number.
