Cylinder block bore is easily damaged. Cylinder block must be replaced if
cylinder block bore is damaged. Insure that puller is properly piloted
before pulling bushing. Failure to comply could result in damage to
Install thrust washer and hex nut. Tighten hex nut until bushing is free of block bore.
Remove puller and discard bushing.
Clean and inspect bore in cylinder block. Cylinder block must be replaced if cylinder
block bore is damaged, refer to paragraph 5.4.8.
Measure camshaft bore inner diameter with bushing removed. Camshaft bore inner
diameter with bushing removed should be 2.3607 - 2.3617 in. (59.961 - 59.987 mm).
Replace cylinder block if camshaft bore inner diameter is out of specification, refer
to Paragraph 5.4.8.
Mark orientation of oil supply hole on front face of engine block and on bushing
using permanent marker.
Apply High Temperature Grease (Appendix E) to inner diameter and outer diameter
of new bushing and to inner diameter of bushing bore. Slide bushing onto Bushing
Installer so notched end of bushing will be toward front end of engine when installed.
Thread Bushing Installer Screw into Removing/Installing Plate. Insure that bushing
is started, square in bore, and oil hole is aligned.
Tighten forcing screw until flange of bushing driver bottoms against face of block.
Remove bushing tool from cylinder block.
Check oil supply hole for correct alignment. If oil supply holes are not aligned,
remove and discard bushing and install new bushing.
Measure and record camshaft bore inner diameter for each remaining camshaft bore.
Camshaft bore inner diameter should be 2.3607 - 2.3617 in. (59.961 - 59.987 mm). Replace
cylinder block if any camshaft bore inner diameter measurement is out of specification.
Calculate and record front camshaft journal-to-front camshaft bushing oil clearance by
subtracting front camshaft journal outer diameter from front camshaft bushing inner
diameter. Front camshaft journal-to-front camshaft bushing oil clearance should be 0.0025 -
0.0045 in. (0.063 - 0.115 mm). Replace front camshaft bushing, refer to step c., or
camshaft, refer to paragraph 5.4.1, as required if front camshaft journal-to-front camshaft
bushing oil clearance is out of specification.
