69J3D11 6-561234567895. Calculate the pinion shim thickness (T3)as shown in the examples below.NOTE:“P” is the deviation of the lower case dimen-sion from standard. The “P” mark a isstamped on the trim tab mounting surface ofthe lower case in 0.01 mm units. If the “P”mark is unreadable, assume that “P” is zeroand check the backlash when the unit isassembled.Example:If “M3” is 50.75 mm and “M4” is 30.52 mmand “P” is (–5), thenT3 = 82.00 + (–5)/100 – 50.75 – 30.52 mm= 82.00 – 0.05 – 50.75 – 30.52 mm= 0.68 mm6. Select the pinion shim(s) (T3) as follows.Example:If “T3” is 0.68 mm, then the pinion shim is0.65 mm.If “T3” is 0.70 mm, then the pinion shim is0.68 mm.Selecting the reverse gear shims1. Turn the thrust bearing 1 two or threetimes to seat the bearing retainer 2, andthen measure the bearing height (M1) asshown.NOTE:• Select the shim thickness (T1) by using thespecified measurement(s) and the calcula-tion formula.• Measure the bearing retainer at threepoints to find the height average.Calculation formula:Pinion shim thickness (T3) =82.00 + P/100 – M3 – M4Calculated numeralat 1/100 place Rounded numeral1, 2 03, 4, 5 26, 7, 8 59, 10 8Available shim thicknesses:0.10, 0.12, 0.15, 0.18, 0.30, 0.40, and0.50 mmDigital caliper 3: 90890-06704Shimming (counter rotation model)
