Reassembling The Tatra

We got back from the Czech Republic the weekend before last. We spent a week there to see how the work on the Tatra was going and to help out a little in putting it back together. We were glad to have the chance to learn more about the construction and modifications, which may also help if we need to make repairs or adjustments during the rally.

In addition to installing the CTIS, the upgrades also involved a few improvements to the suspension, including the air bellows that are part of the pneumatic suspension. The original Tatra 4×4 bellows were replaced with a smaller lighter version designed for the Tatra 6×6, which has eight bellows on the two rear axles. The Tatra 4×4 has only four bellows on the rear axle. Comparatively, even though the Tatra 6×6 can haul a heavier load, each of the bellows on the Tatra 4×4 are designed for a heavier load because there are only half as many to support the total weight. Since we’re preparing our Tatra for racing, we won’t be carrying anything heavy, and we can afford to change the bellows to the lighter 6×6 version, which is more reactive and should make a smoother ride during the race.

While we were there, the engine was remounted.

We also mounted the front wheels.

It’s usually hard to see the front axle because of the skid plate, but because it hasn’t been remounted yet, the newly painted axle is easy to spot.

The CTIS has been completely installed and tested in the workshop. The air pipe on the hub will be protected by a cover. It has a vane so that it can be isolated and so the tire can be inflated normally in case of a problem.

This is how it looked when we left.

Unfortunately, we weren’t able to stay for the first tests this week, but we’re planning to go back for some offroad tests soon.
