We discovered that the steering gear did not work correctly when we turned to the right. Now the problem has been fixed, but it took some time and a lot of thought was needed to determine what the error was, but also to understand how the steering gear actually works.

It’s almost time
The engine frame is mounted in place in the body.
The steering gear is checked and adjusted after the test runs and as soon as all parts are mounted we lift the steering gear onto the underbody.
Finally it is time to assemble the body and the underbody to a unit.
The engine in place
The body and the engine frame are now assembled to a unit, but some bolt connections are missing before the body can be lifted onto the underbody. But before that, the underbody must be cleaned and rustproofed.
Body and engine frame joined.
The body and the underbody stand next to each other again.
Preparations for final assembly
The power line is tested and it works properly.
The next step is to mount the body on the base, but there are some preparations that must be made first. With the help of a wheel loader, the engine frame with the engine and the gearbox is taken away. The body and the engine frame must be assembled to a unit before the body is mounted on the base.
Adjustment of the steering gear
Finally we have got a run on the steering gear. We have run a number of times and the total mileage is between 500 and 600 m. The steering is a type of clutch/brake and it has taken time to adjust, because just as the clutch begins to release, the brake must be applied. Therefore, a lot of time and many practical tests have been required before the steering gear was properly adjusted.
In the movie below we see one of the first test runs.
Preparing for the next test run
At the first test run we did not have all the controls connected. We had to drive at constant engine speed. Now we have connected the throttle linkage, choke and ignition adjustment so at the next test run we have significantly better opportunities to perform a controlled test of all functions.
Fuel and electrical systems mounted
The fuel tank and battery are now mounted on a plate at the bottom of the frame. When the panels come into place, they are not visible, but will be easy to access.
The electrical system is provisionally connected to all functions that are related to the engine (start, stop and fuel pump). The instrument board is mounted for easy access from the driver.
Test run time
After 80 years it’s time to move for its own machine. Absolutely amazing to see. Not to mention the curve technique, a great pleasure.
Then it was time to get back into the workshop, because there is still a lot to do before everything is ready.
Preparations for test run
Now it is time to test the wagon. But since it has not rolled for its own machine since the early 40’s, there are a lot of preparations to make before it’s time to start the engine and roll away.
A highly concentrated driver is prepared.
Both tracks mounted
Now we are back after Christmas and New Year’s leave and the first thing we did was to mount the right track. There was a lot of violence required to get to the last track plate, but then the track went on very well.
The next step is to check that the drive and, above all, the steering work as it should.
