126 ENGINE AND ENGINE REBUILDING
Fabricate a roll-out pin as illustrated, if necessary
the main bearing cap. Install the main bear-
ing cap, making sure it is positioned in proper
direction with the matchmarks in alignment.
6. Torque the main bearing cap bolts to
specification.
NOTE:
The thrust bearing must be aligned
before torquing cap bolts.
CRANKSHAFT INSTALLATION
When main bearing clearance has been
checked, bearings examined and/or replaced,
the crankshaft can be installed. Thoroughly
clean the upper and lower bearing surfaces,
and lube them with clean engine oil. Install
the crankshaft and main bearing caps.
Dip all main bearing cap bolts in clean oil,
and torque all main bearing caps, excluding
the thrust bearing cap, to specifications (see
the "Crankshaft and Connecting Rod" chart
in this chapter to determine which bearing is
the thrust bearing). Tighten the thrust bear-
ing bolts finger tight. To align the thrust
bearing, pry the crankshaft the extent of its
axial travel several times, holding the last
movement toward the front of the engine. Add
thrust washers if required for proper align-
ment. Torque the thrust bearing cap to spec-
ifications.
To check crankshaft end-play, pry the
crankshaft to the extreme rear of its axial
travel, then to the extreme front of its travel.
Using a feeler gauge, measure the end-play
at the front of the rear main bearing. End play
may also be measured at the thrust bearing.
Use a feeler gauge to check crankshaft end play
during assembly
Install a new rear main bearing oil seal in the
cylinder block and main bearing cap. Con-
tinue to reassemble the engine in reverse of
disassembly procedures.
