Removal & Installation
1) Use Camshaft Bearing Remover/Installer (C-3132-A) for
camshaft bearing replacement. Replace camshaft bearing if damaged or
if I.D. is not within specification. See CAMSHAFT table under ENGINE
SPECIFICATIONS.
2) Ensure oil holes are aligned. Ensure oil hole in No. 2
bearing aligns with oil hole to left cylinder head, and oil hole in
No. 3 bearing (3.9L) or No. 4 bearing (5.2L and 5.9L) aligns with oi\
l
hole to right cylinder head. Install NEW camshaft plug at rear of

and distributor drive shaft bushing into cylinder block.
CAUTION: DO NOT ream distributor drive shaft bushing.
2) Using hammer, drive bushing installer and distributor
drive shaft bushing into cylinder block. Tighten nut to pull bushing

paint toward rear of engine.
3) To prevent oil leakage, apply one drop of Loctite 515
sealant next to oil seal on main bearing cap surface before
installing. Apply silicone adhesive sealant at bearing cap-to-cylinder
block joint. See Fig. 11. Install main bearing cap, and tighten bolts
to specification. See TORQUE SPECIFICATIONS table. To install
remaining components, reverse removal procedure.
Removal & Installation (Crankshaft Removed)

oil pan, apply RTV sealant where front cover contacts cylinder block,
where oil pan side gaskets meet end seals, and where end seals contact
cylinder block. See Fig. 14.
2) To facilitate oil pan installation, fabricate 4 alignment
dowels from 1 1/2" x 5/16" bolts. See Fig. 15. Tighten bolts to
specification. See TORQUE SPECIFICATIONS table. To install remaining
