Measure camshaft bushing inner diameter and camshaft journal outer diameter as follows:
Measure and record camshaft journal outer diameter for each camshaft journal. Camshaft
journal outer diameter should be 2.1997 - 2.2007 in. (55.872 - 55.898 mm). Replace
camshaft and camshaft followers if any camshaft journal outer diameter is out of
Measure and record front camshaft bushing inner diameter. Front camshaft bushing inner
diameter should be 2.2031 - 2.2042 in. (55.961 - 55.987 mm). Replace front camshaft
bushing as follows if measurement is not within specification.
Remove countersunk TORX®7 cap screw and install M8 X 1.25 tapered bottom
leg from Camshaft Bushing Service Kit into hole that has chamfered screw and
Install M8 X 1.25 flat bottom legs and Removing/Installing Plate to cylinder
block so plate is parallel with front plate and centered over camshaft bore.
Tighten legs and hex nuts securely.
Insert Bushing Remover into camshaft bore so puller pilots in bushing inner
diameter and Bushing Installer Screw extends through plate.
Cylinder block bore is easily damaged. Cylinder block must be replaced if
cylinder block bore is damaged. Ensure 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 5.4.7.
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 5.4.7.
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. Ensure that
bushing is started, square in bore, and oil hole is aligned.
