REPAIR INSTRUCTIONS, PART 1
Page 213
The camshaft is heavy. Do NOT attempt to
install the camshaft without the help of an
assistant or the use of a suitable lifting
device. Failure to heed this warning may
result in severe personal injury and
component damage.
Before installing a camshaft, be sure that it is
clean, undamaged and well lubricated with clean
engine oil. Refer to Camshaft Bench Procedures
in the REPAIR INSTRUCTIONS section.
This procedure presumes that the upper
camshaft bearing caps are in place on the
cylinder head. Keep the bearing caps in sets.
Return the upper cap to the lower cap from which
it was removed. The lower caps are assembled
on guide sleeves in the cylinder head. If the lower
caps are removed, they must be returned to their
original location.
1. Mark the bearing cap sets and remove the
upper bearing caps.
2. Apply a generous coating of clean engine oil
to the camshaft bearings.
3. Make sure there is a bearing insert on each
lower bearing cap. The bearing inserts at the
No. 7 camshaft journal have integral thrust
washers.

4. Clean the camshaft with a suitable solvent.
5. With an assistant and the camshaft lifting
bar, 85109034, position the camshaft on the
lower bearing caps and install the upper
bearing caps and seven outboard screws.
6. Insert and hand-tighten the outboard
screws. Final tightening to the specified
torque value will be done later when the
rocker arm shaft is installed.
