TIMING CHAIN
• Measure outer diameters (d1, d2)
at the two positions as shown.
• Measure d2 within the range (A).
• If the value difference (d1 - d2) exceeds the limit, replace the bal-
ancer unit bolt with a new one.
INSTALLATION
1. Make sure the crankshaft key points straight up.
2. Install the balancer unit and tighten the bolts in the numerical order as shown:
CAUTION:
• When reusing a bolt, check its outer diameter before installation. Follow the Balan cer Unit Bolt Outer Diameter
procedure.
• Apply new engine oil to threads and seating surfaces of bolts.
• Check tightening angle with an angle wrench (A) or a pro- tractor. Do not make judgme nt by visual check alone.
3. Install the crankshaft sprocket (1) and timing chain (2) for the balancer unit.
• Make sure that the crankshaft sprocket (1) is positioned with
mating marks (A) on the block and sprocket meeting at the
top.
• Install it by lining up mating marks on each sprocket (A), (C) and timing chain (B), (D).
• (B): Pink link
• (D): Yellow link Limit : 0.15 mm (0. 0059 in) or more
