Terra-Lite TL 85 on a Ponsse Forwarder

Step-by-Step Guide

Stage 1
Lay out the track with the track paws face down.

Stage 2
Use a good quality strong rope, such as nylon with a Ø20mm, and attach it to the centre of the last track plate.

Feed over the middle of the bogey tires, and place the excess rope under the second tire as shown in the diagram below. The rope should be jammed tightly in place.

Stage 3
Drive the machine forward so that the wheels bite down on the rope trapped underneath, as shown in the diagram. This will haul the tracks onto the rear tires.

Stage 4
When the track is sitting fully on the machine as shown in the diagram, the two fitting staples (supplied with the track) can be inserted to hold the ends together. The rope should now be removed.
Each section of track has been manufactured to a standard length so plates might need to be removed in order to achieve the correct tension. This is dependent upon whether the track is fitted to new or worn tires and can also vary due to machine type and bogey design.

Stage 5
Drive the machine forward so that the stapled section is in the centre of the bogey.

Stage 6
The track Tensioner should then by placed on either end of the track, on either the right or left side, and a ratchet used to tighten the track. The staple should then be replaced by the track joining link. This process is then repeated on the other side of the track.

Fitting of track joining links
These links must be fitted with the smooth surface of the link facing towards the tire, with the end plate fitted to the outside. Fitting these links the wrong way round can result in tire damage with the link pins contacting the tire side wall.

Stage 7
Ensure correct track tension. Where tracks are run too slack, with excessive amount of centre sag, there are potential problem with tracks falling off. There is also a danger of tracks hitting and rubbing on bogey drive boxes and in extremely neglected cases, wearing grooves and holes in the drive box.
