Rear Cover Removal

• Remove the rear cover bolts. Use a rubber
hammer to loosen the cover from the
crankcase but do not remove. Separate
the rear cover from the crankcase gasket
and the high-pressure pump cover gasket.
• Caution: Failure to separate the rear
cover from the crankcase gasket and
pump cover gasket could result in damage
to both gaskets. Engine removal and
disassembly would be required to replace
the lower crankcase gasket. Replacing the
pump cover gasket would require the
turbocharger, intake manifold and pump
cover to be removed.

Front Cover Removal

• A small quantity of liquid gasket (RTV) is
used at the crankcase to lower crankcase
joint. Cut the sealant between the gasket
and the front cover and between the
gasket and the crankcase before removing
the cover.
• Caution: To prevent engine damage cut
the sealant where the crankcase and lower
crankcase meet when removing the front
cover.
sealant prior to remove the front cover or
the front cover gasket, could cause the
lower crankcase gasket to be pulled out.
Complete engine disassembly will be
required to replace the crankcase gasket.

Primary Balance Weight Removal

• The primary balancer shaft runs within the
camshaft
counterweight. To remove the counter-

weight, remove the 10mm balance shaft
counterweight bolt and the three 6mm
thrust plate bolts (removal of the third bolt
will require rotating the crankshaft to
uncover the bolt). The thrust plate fits in a
groove cut in the counterweight. The
difference between the thickness of the
thrust plate and the width of the groove cut
in the counterweight determines the
primary shaft endplay. The counterweight
is timed to the primary balance shaft by a
flat on the shaft and a flat on the
counterweight.
