lRemove crankshaft gear (1) with the following procedure
(4WD models).
a. Make sure that No.1 piston is TDC on its compression stroke.
b. Turn the idler sub gear (3) counterclockwise with snap ring plier
(B) or suitable tool for aligning idler sub gear (3) and idler main
gear (2).
lIf idler gear rotates, hold the flat faces on balancer drive shaft
front end (4).
c. Install internal mechanism securing bolt and plate (Service part:
13012 EB30A and 13013 EB30A) (A) and tighten to the speci-
fied torque.
CAUTION:
lDo not loosen idler gear mounting bolt (5).

and plate (A), or the idler gear (2) and (3) will be damaged.
lDo not remove internal mechanism securing bolt and
plate (A) from idler gear (2) and (3) until crankshaft gear
(1) and all of the parts in connection have been installed.
lIf internal mechanism securing bolt and plate (A) is not
installed, internal mechanism of idler gear (2) and (3) will
