SLS undercarriage for the Multi Terrain Loader (1) Track (2) Hydrostatic piston motor (3) Drive sprocket (4) Axles (5) Idler (6) Tensioner (7) Bogies | |
The SLS undercarriage is mounted to the lower frame through the axles (4). The part of the axles that are attached to the undercarriage allow each side of the undercarriage to flex independently of the other side.
The SLS undercarriage consists of the following components: track (1), hydrostatic piston motors (2), drive sprockets (3), axles (4), idlers (5), tensioner (6) and bogies (7) .
The hydrostatic piston pump 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.

The bogies (7) are mounted directly to the frame (8) of the undercarriage. There are ten bogie assemblies in each side 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 develop slippage.
- Damage may occur to the drive lugs on the track.
- The track may come off.
- The track may wear prematurely.
- Power loss may occur.
- The bearings may fail.

The DLS undercarriage is mounted to the lower frame through the axles (12). The part of the axles that are attached to the undercarriage allow each side of the undercarriage to flex independently of the other side.
The DLS undercarriage consists of the following components: track (9 ), hydrostatic piston motors ( 10), drive sprockets (15 ), axles (12 ), idlers (13), tensioner (11 ) and bogies (14 ) .
The hydrostatic piston pump 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.
The bogie assemblies (16) are made up of two bogies (14) that are bolted together over four rubber cords (18) onto an axle (17). The four rubber cords (18) allow the bogie assemblies to follow the contour of the ground. There are four bogie assemblies (16) in each side of the undercarriage.
The tensioner (11) 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 develop slippage.
- Damage may occur to the drive lugs on the track.
- The track may come off.
- The track may wear prematurely.
- Power loss may occur.
- The bearings may fail.
