Balance Shaft, Removing And Installing, Intake Side: Installing
-- Lubricate the balance shaft mountings -arrows- with engine oil.
-- Install the intake side balance shaft and tighten the bolt -2-.
-- Replace the O-ring -1- and coat with engine oil.
-- Coat the mounting pin with engine oil and insert it. The alignment pin -arrow- for the mounting pin must engage in the hole in the cylinder block.
Always replace the intermediate sprocket. Otherwise the backlash will not adjust itself and it could result in engine damage.
The new intermediate sprocket has an anti-friction coating that wears off after a short period of use, which automatically adjusts the backlash.
-- Mark the tooth flank on the intermediate sprocket -arrow-.
-- Install the intermediate sprocket; the marking on the balance shaft must be between the markings on the tooth flanks.
-- Tighten the bolt -1- for the intermediate sprocket: tightening sequence. Refer to Fig 5.
-- Check the markings on the intermediate sprocket/balance shaft -arrow-.
