Work on the chassis

In autumn 17 the work on the chassis started. Part of the chassis work was done at the end of the completion process.

 

Engine / gearbox / tires

  • New front protection plate for the engine, because the Mercedes Vario unfortunately has a plastic oil pan
  • Replacement of the standard valve by a Rölex valve to protect the oil pan
  • Removal of the speed limit of 80kmh (vehicle will be registered as an RV and not as a truck anymore)
  • As it is too expensive to replace the shorter gear transmission through a longer gear transmission (to reduce rpm) we decided to install larger Michelin tires XZY 9.5 R17.5, which are still approved by Mercedes Benz

Driver cabin

  • Removal of the flooring and replacement with noise-reducing materials
  • Burglary protection for driver and passenger doors

Chassis optimisation

  • Sandblasting of the chassis, anti-corrosion treatment and new painting in black
  • Sandblasting of the tire rims, anti-corrosion treatment and new painting in black
  • Heavy duty shock absorbers by MARQUART, to reduce swing movements of the vehicle while driving
  • Triple leaf springs on the front axle instead of double leaf springs
  • Removal of the heavy trailer hitch and of all power connections to the trailer to save weight
  • Removal of the spare tire holder under the chassis, as spare tire will be placed on the back side of the body
  • Exhaust: moved forward to make room for an additional diesel tank and pipe lifted to improve ground clearance

Larger tires

We replaced the tires sized 215/75 R17.5 by new Michelin XZY 9.5 R17.5. These new tires are designed for onroad and offroad. In addition, the tires have an approval for use during winter. On the other side:  New rims 6.75 x 5.17 are required. Rims are painted in black.

 

Important: This tire format has the official approval by Mercedes Benz.

 

The following pictures illustrate the size difference to the old tires. As a result, with the new tires we achieve nearly 4 cm more ground clearance and a 10% reduction in rpm.
