Information
The timing-case cover must not project over the crankcase. The maximum offset is → Length: 0.1 mm .
- 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.
- 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.
- Measure offset. To do this, push with the bracket starting from the lower part of the crankcase towards the timing-case cover (the base of the dial gauge bracket is not located on the same component as the dial gauge probe) and measure the offset. Measuring the setback distance. The timing-case cover must not be set back by more than 0.1 mm. Even the slightest projection must be corrected.
- Align the timing-case covers by tapping lightly with a rubber hammer.
- Once you have aligned the timing-case cover, tighten two fastening screws on the left and right of the timing-case cover base hand-tight. Then check the position of the timing-case cover again using the dial gauge.
