The undercarriage of the 267, 277, and 287 Multi Terrain Loaders is mounted to the lower frame through the axles (4). The axles allow each side of the undercarriage to flex independently of the other side.
The undercarriage consists of the following components: track (1), piston motors ( hydrostatic) (2), drive sprockets (3), axles (4), idlers (5), tensioner (6) and bogies (7) .
The piston pump ( hydrostatic) provides oil flow to the piston motors. The piston motors are directly connected to the drive sprockets. When the motors turn, the drive sprocket turns with the motor. The drive sprocket engages the lugs on the track and the track rotates around the idlers, the bogies, and the tensioner.

Suspension group for (S/N: CNC1-1199) and (S/N: CMP1-699) (7) Bogies (8) Suspension frame | |
The bogies (7) on the 267 and 277 ride inside the suspension frame (8). There are two bogies per suspension group. The suspension group can pivot about the suspension frame. This allows the machine to travel over rough terrain smoothly.

Undercarriage frame and bogies for (S/N: CNC1200), (S/N: CMP700), and (S/N: CNY1) (7) Bogies (9) Frame | |
The bogies (7) for the 287 are mounted directly to the frame (9) of the undercarriage.
The tensioner (6) adjusts the tension on the track. Refer to the Operation and Maintenance Manual, "Track (Rubber) - Inspect/Adjust" for the proper procedure for adjusting the track tension.
If the track tension is not adjusted properly any of the following items may occur:
- Track slippage
- Damage to the drive lugs on the track.
- The track may come off.
- The track may wear prematurely.
- Power loss.
- The bearings may fail.
