NOTE;
. Use a straight edge and depth gauge.. Measure at three locations and average the read-ings.
Select the prcpet 72 mm thrust shim from the chartby using the formula below.
NOTE: Us€ only one 72 mm thrust sntm.
Shim Selection Formula:
From the measurements you made in steps 4 and 5:. Add distance O lstep 5) to distance @ (step 4).
. From this number, subtract 0.93 (which is themidpoint of the flex range of the clutch housingbearing spring washer).
. Take this number and compare it to the availableshim sizes in the chart.
{For example)
B;2.39
+ C: 0.22- 0.93

Try the 1.68 mm (0.0661 in) shim.

1. Set the parking brake, and btock both rear wheels securely.
2. Start the engine, and run it at 2,OOO rpm.
3. Shift to N or E position, then measure line pressure.
NoTE: Higher pressure may be indicated if measurements are made in shift lever positions other than @ or @ positron.
4. Shift to tq;l position, hold the engine at 2,000 rpm, and measure 1st crutch pressure.
