CRANKSHAFT ENDFLAY
After the rear bearing end plate has been tightened
using the torque recommended in Assembly Torques
and Special Tools section, check the crankshaft
endplay as shown in Figure 79. If there is too much
endplay (see Dimensions and Clearances section for
minimum and maximum endplay), remove the rear
bearing end plate and replace the gasket with a
thinner gasket from the gasket kit. For too little
endplay, remove the rear bearing end plate and
replace the gasket with a thicker one. Reinstall the
end plate making sure the thrust washer notches line
up with the lock pins. Torque and recheck endplay of
the crankshaft.
OIL PUMP
Check the oil pump thoroughly for worn parts. Oil the
pump to prime it before reinstalling, Figure 80. Except
for gaskets, the component parts of the pump are not
available individually. The suction cup is available
separately. Install a new pump assembly. If required.
