The wheel casing is a notorious noise crack. Here there are a few problems for:

In the floor of the wheel casing there is a large hole through which pipes and cable pass through. The noise is transmitted through this hole from the engine room mainly straight into the wheel casing. Apart from this noise comes through gaps or straight through the wood in the wheel house.

This problem is to be solved by sealing this hole well, for example with PUR-foam. As an extra measure you can insulate the inner side of the wheel casing with a mass plate Isomat TS 8, which you must glue with Saba Select contact glue. Over this you stick a layer of noise absorbing foam. Tecnocell 25 mm is more than suitable for this job.

A second problem that arises is the Morse-control. Gas is given by a morse cable. This is a massive still cable which is fixed to the engines gas handle. Vibration energy from the engine is transported via the massive steel cable to the wheels casing. There are two ways to avoid it.

• Make sure that the control cable does not lie against anything.
• Cover the casing with Isomat TS 8 en Tecnocell as is it described above.
