To make sufficient room for an added third crew member, the radio operator, the gear box was moved to the front of the vehicle.

The driver let it warm up for a while, and set to work on the gear box, which had not yet thawed.

And, we had it the one with the gear box.

It has a 6-speed gear box, and is chain driven.

The car also acquired a new name and a new gear box.

The ratio of the gear box used was 1:1.5.

Both vehicles have a 5-speed gear box and a 2-speed transfer box.

The gear box is changed so the tank can have 360 degrees turret turn.

This means the sounds are in harmony, so the gear box make a more musical noise.

The new test part was a gear box that must be machined on all six sides.
