Timing
TIMING1. With balance shafts installed in carrier, position carrier on crankcase and install six attaching bolts and tighten to 54 N.m (40 ft. lbs.).
2. Turn balance shaft until both shaft key ways are up Parallel to vertical centerline of engine. Install short hub drive gear on sprocket driven shaft and long hub gear on gear driven shaft. After installation gear and balance shaft keyways must be up with gear timing marks meshed.
3. Install gear cover and tighten double ended stud/washer fastener to 12 N.m (105 in. lbs.).
4. Inatall crankshaft sprocket and tighten socket head torx screw to 13 N.m (130 in. lbs.).
5. Turn crankshaft until number one cylinder is at Top Dead Center (TDC). The timing marks on the chain sprocket should line up with the parting line on the left side of number one main bearing cap.
6. Place chain over crankshaft sprocket so that the nickel plated link of the chain is over the timing mark on the crankshaft sprocket.
7. Place balance shaft sprocket into the timing chain, so that the timing mark on the sprocket (yellow dot) mates with the (lower) nickel plated link on the chain.
8. With balance shaft keyways pointing up (12 o'clock) slide the balance shaft sprocket onto the nose of the balance shaft. The balance shaft may have to be pushed in slightly to allow for clearance.
NOTE:
- The timing mark on the sprocket,the (lower) nickel plated link, and the arrow on the side of the gear cover should line up if the balance shafts are timed correctly.
9. If the sprockets are timed correctly install the balance shaft bolts and tighten to 28 N.m (250 in. lbs.). A wood block placed between crankcase and crankshaft counterbalance will prevent crankshaft and gear rotation.
