1. Use No. 536613 crankshaft socket to rotate the crankshaft to TDC #1 on the compression stroke. Rotate the crankshaft counterclockwise (CCW) until the timing mark on the crankshaft is at the 6:00 position.
2. Use No. 536613 crankshaft socket to rotate the crankshaft 60° counterclockwise (CCW).
3. Install No. 536596 to the crankshaft sprocket with the knurled bolt. The moveable lever of No. 536596 must be in the bottom of the slot.
4. Rotate the crankshaft clockwise (CW) until the arm of No. 536596 contacts the water pump pulley flange. Secure the moveable lever of No. 536596 to the water pump pulley flange. The #1 cylinder is at TDC on the compression stroke.

1. Set the engine at TDC #1 compression stroke.
2. Assemble No. 536608 camshaft alignment gauge on timing gears #1 & #2 as shown.
3. The timing marks must line up exactly with the marks on the camshaft alignment gauge. If they are perfectly aligned, proceed to step 4. If they are not perfectly aligned, the timing belt will have to be removed, the engine put back in time, and the timing belt reinstalled.
4. Assemble No. 536608 camshaft alignment gauge on timing gears #3 & #4 as shown.
