The camshaft is heavy, approximately 90 pounds
with the gear. The installation guide allows the
camshaft to slide from one cam bushing to the
next without allowing the cam to drop when one
journal clears the bushing bore.
10. Slide the camshaft into the block with the
cam installation guide facing down toward
the floor. Refer to Figure 318.
11. Slide the cam all the way into the block.

12. After the camshaft is fully installed, install
the thrust washer screws and tighten to
specification.
13. Rotate the crankshaft and camshaft to
facilitate installation guide removal. The
camshaft must be rotated so that the
installation guide faces the cylinder block
pan rail. The crankshaft must be rotated so
the No. 6 connecting rod journal faces the
cylinder block top deck (piston at TDC).
14. Remove the installation guide tool J 41682.
[213] CAMSHAFT IDLER GEAR
INSTALLATION
Before installing the idler gear/hub assembly,
determine which is the top mounting hole on the
hub.
The idler gear is held in place by a flanged hub
mounted to the cylinder block by three bolts.
Although the bolt-mounting pattern may
appear
symmetrical, it is not. The non-symmetrical
mounting pattern ensures that oil feed passages
in the hub will be properly aligned with the oil feed
passage in the cylinder block, which lubricates
the idler gear hub bushing.
To aid in aligning the hub to the mounting holes in
the cylinder block, the hub mounting-bolt hole at
the 12 o’clock position (engine upright) is
identified by the word “UP” steel-stamped just
below the mounting hole. Refer to Figure 319.
1. With the engine in an upright position and
the hub correctly aligned with the mounting
bolt holes, place the idler hub against the
block and verify good mounting-hole
alignment.
