Slide indicator probe off of height block and onto Arbor Bar D-115-3 (2). As indicator contacts Arbor Bar (2), indicator needle will rotate clockwise. Continue moving indicator probe to the crest of the arbor bar and record the highest reading. Then add 4 mm (0.157 in.) to the recorded reading. This will give you the correct shim selection for pinion height.
