Shim Selection Formula

1. Select the proper 82 mm shim from the chart. Follow the example below, and use the measurements you made in Step 3 and 4.
   (Basic Formula)

   (2) − (1) − (0.85 + 0.14) = | shim thickness (maximum)
   (2) − (1) − (0.85 + 0.21) = | shim thickness (minimum)

   - Subtract distance (2) ( Step 4 ) from distance (1) ( Step 3 ).
   - 0.85 mm (0.033 in.): Spring washer, a dimension in the installation.
   - 0.14 mm (0.006 in.): Minimum thrust clearance.
   - 0.21 mm (0.008 in.): Maximum thrust clearance.
   (For example)

   21.04 − 17.97 − (0.85 + 0.14) = 2.08 mm (0.082 in.)
   21.04 − 17.97 − (0.85 + 0.21) = 2.01 mm (0.079 in.)

   Take the middle value 2.04 mm (0.080 in.) of the minimum value and the maximum value, and select the 0.93 mm (0.037 in.) and 1.11 mm (0.044 in.) shims.
   NOTE: You may need to select two thicknesses of the 82 mm shim from the chart.

1. Install the 82 mm shim (A) selected in the transmission housing (B).

1. Throughly clean the spring washer before installing it on the clutch housing. Note the installation direction of the spring washer.

1. Install the mainshaft in the clutch housing.

1. Place the transmission housing over the mainshaft and onto the clutch housing.

1. Tighten the clutch and transmission housings with several 10 mm bolts.
   NOTE: It is not necessary to use sealing agent between the housings.

1. Lightly tap on the mainshaft with a plastic hammer.
