7. Ensure that the balance shafts spin freely.
8. If the balance shaft housing was disassembled, install the oil pump pick-Lip screen into the housing. Lightly tap it into place with a plastic
hammer.
Important: If the balance shafts are not properly timed to the engine, the engine may vibrate or make noise.
9. Install the timed balance shaft and housing assembly to the engine using the following steps:
9.1. Place the number one piston at TDC.
9.2. Rotate the crankshaft 90 degrees.
9.3. Install the J 38122 on to the balance shaft assembly to ensure the shafts do not rotate while the driven sprocket bolt is tightened.
Notice: A new balance shaft driven sprocket bolt must be used any time the bolt is removed. If a new bolt is not used, the balance shaft sprocket
may slip allowing the balance shafts to become mistimed and cause engine vibration.
Important: The surface that was marked during disassembly of the driven sprocket must show if it is going to be reused. This will insure that the
chain continues to ride on the same surface. If a new driven sprocket will be installed, either surface can be placed against the shaft.
10. Install the driven sprocket to the shaft.
Important: The balance shaft driven sprocket bolt is left hand threaded and must be tightened by rotating it in a counter clockwise direction.
11. Install the driven sprocket bolt. Finger tighten.
12. Install the balance shaft chain guide.
