Tighten to 7 in. lbs. of torque.
Do not over torque. Incorrect readings will be produced. Make sure the countershaft rear bearing cover gaskets have been removed.
Rotate the output shaft six times in the clockwise direction, then six times counterclockwise to properly seat the bearings. Use a feeler gauge to measure the clearance between the shim gauge and auxiliary housing surface near each capscrew location. Record each measurement and average the two measurements. Refer to the Shimming Endplay Chart and select the number in the left column which corresponds to the average measurement which was achieved. Follow the column to the right to determine the proper thickness and shim required. Note part number and shim color. Repeat this procedure for the other countershaft.
