Fitting Oil Guide Housing Using A Dial Gauge

Information 

When installing the oil guide housing, make sure that it is perfectly aligned and that there is no dirt or dust between the components. Fit the oil guide housing straight. The maximum offset must be less than 0.1 mm and it must not project over the crankcase. Otherwise, leaks can occur while driving.

Information 

• The following work steps are only necessary if the transmission is disconnected at the time the oil guide housing is being installed  .

Place the oil guide housing on the crankcase and fit a fastening screw on each corner.

1. Insert the dial gauge into the universal dial gauge bracket and position it so that the dial gauge has a preload of about 1 mm.

2. Set dial gauge scale to 0. To do this, place the dial gauge bracket on a completely flat surface (e.g. crankcase flange) and turn the dial gauge scale until the pointer is at 0.

3. Measure the offset. In order to do this, push with the bracket starting from the crankcase flange towards the oil guide housing flange (the foot of the dial gauge bracket is located on the other component like the dial gauge probe) and measure the offset. The oil guide housing must not be set back any more than 0.1 mm. Even the slightest projection must be corrected.

4. Align the oil guide housing by tapping lightly with a rubber hammer.
5. Once the oil guide housing is aligned, tighten the four fastening screws. Then check the position of the oil guide housing again with the dial gauge.
