Using the following calculation, calculate the transfer drive gear adjusting washer value "t". t = {Y - 15 mm (0.59 in)} - {Z - 15 mm (0.59 in)} - 0.75 - 0.95 mm (0.030 - 0.037 in)

t mm (in)	Transfer drive gear adjusting washer thickness
Y mm (in)	Depth between the end of the ST and the transfer drive gear
Z mm (in)	Height from the end of the transmission case to the end of the ST.
0.75 - 0.95 mm (0.030 - 0.037 in)	Standard clearance between the adjusting washer and transfer drive gear
15 mm (0.591 in)	Thickness of ST

Refer to the calculated value "t" to select the closest adjusting washer from the following table.
