Counterbalance Drive Chain: Installation

1. To install, reverse removal procedure. Ensure mating marks on sprockets align with plated links on counterbalance chain. Adjust tension by installing guides "A" and "C".
2. Shake counterbalance shaft sprockets to take slack from chain. Adjust guide "B" so there will be .040-.140" (1.0-3.5 mm) clearance between guide and chain at point "P". Tighten guide mounting bolts and complete assembly.
