ASSEMBLY
CAUTION
If cylinder block is not to be used immediately, spray machined surfaces with engine oil. If
cylinder block is to be stored for an extended period of time, spray or dip block with
corrosion preventative. Castings free of oil will rust when exposed to atmosphere.
NOTE
Install camshaft intermediate bearings prior to installing camshaft end bearings
and press into cylinder block from outboard end of bore.
Notch in front end and front intermediate bearings is toward front of engine. Notch
in rear end and rear intermediate bearings is toward rear of engine.
Camshaft replacement bearings are available with either standard or oversized
outside diameter and standard or undersized inside diameters (see Table 2).
Camshaft bearing remover and installer set is designed for use with standard size
bearings. To install undersized bearings, reduce outside diameter of pilot,
installers, and remover by 0.020 in. (0.51 mm).
