Aligning Timing-Case Cover Using A Dial Gauge

Information 

The timing-case cover must not project over the crankcase. The maximum offset is → Length: 0.1 mm  .

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. → see Fig 1

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. → see Fig 2

3. 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 → see Fig 3. The timing-case cover must not be set back by more than 0.1 mm. It must not project out.

5. 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. → see Fig 5
