<< A >> Balancer Shaft And Oil Pump Module Removal

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

CAUTION:

Never turn the crankshaft counterclockwise.
Never turn the crankshaft after the number 1 cylinder or number 4 cylinder is set to the top dead center of compression.

Turn the crankshaft clockwise to align the timing mark of the balancer shaft sprocket with the timing mark of the balancer shaft and oil pump module, and set the number 1 cylinder or number 4 cylinder to the top dead center of compression.
Put paint mark on the balancer shaft sprocket timing mark and balancer timing chain.

CAUTION: Securely install the plunger of the timing chain tensioner. Otherwise, it may pop out.
Press the balancer timing chain against the timing chain tensioner, compress the plunger of the timing chain tensioner and insert L-shaped hard wire (piano wire, etc.) or L-shaped hexagon wrench [1.5 mm (0.05 inch)] to the plunger fixing hole of the timing chain tensioner from under the timing chain case, and fix the plunger of the timing chain tensioner.

Use a wrench to remove the mounting bolt at the lower side of the balancer timing chain guide shown in the figure so that the balancer timing chain guide is unrestricted.
Support the balancer shaft and oil pump module with a hand, and remove the balancer shaft and oil pump module mounting bolts.

CAUTION: When the tooth jump of the balancer timing chain from the crankshaft sprocket occurs, the timing between the balancer shaft and the oil pump module becomes off, resulting in the abnormal engine vibration. Be sure that the tooth jump will not occur.
After the balancer shaft and oil pump module is removed, using a cable band, tie the balancer timing chain at the protrusion of the rudder frame to prevent the tooth jump of balancer timing chain from the crankshaft sprocket.
