WARNING: This page is about a different variant/trim than selected.

When installing the new balancer shaft and oil pump module, apply oil to the oil pump in the balancer shaft and oil pump module and the balancer shaft bearing as follows.
1. Clean the inside of the removed engine oil pan, and put the balancer shaft and oil pump module into the engine oil pan with its oil inlet port facing up.
2. Pour new engine oil until two-thirds of the balancer shaft and oil pump module is soaked.
3. Fill the new engine oil [approximately 50 cm³ (3.05 cu.in.)] into the balancer shaft and oil pump module from the oil inlet port.

With the link marks (orange or blue) of balancer timing chain aligned with the timing marks of balancer sprocket and crankshaft sprocket, install the balancer shaft and oil pump module together with the balancer timing chain and crankshaft sprocket as one unit to the cylinder block. At this time, securely bring the balancer shaft and oil pump module into contact with the rudder frame mounting area.
Apply an adequate and minimum amount of engine oil to the threads and bearing surfaces of the balancer shaft and oil pump module mounting bolts.
