(1) Track
(2) Piston motor ( hydrostatic)
(3) Drive sprocket
(4) Axles
(5) Idler
(6) Tensioner
(7) Bogies The undercarriages of Multi Terrain Loaders are 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. Power from the piston motors is transferred to the drive sprocket through the planetary outboard final drives. The drive sprocket engages the lugs on the track and the track rotates around the idlers, the bogies, and the tensioner.The bogies (7) are mounted directly to the frame 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:
The track may slip.
Damage to the drive lugs on the track.
The track may come off.
The track may wear prematurely.
Power loss.
The bearings may fail.
