OIL COMPONENT
SERVICING
IMPORTANT: Access to certain oil distribution
hoses requires removal of various engine compo-
nents. Refer to service information in the various
sections of this manual for additional information
related to the removal and installation of specific
components. DO NOT disassemble or replace
any oiling system components until you are famil-
iar with the entire OILING SYSTEM section.
Oil Distribution Hoses
The oil distribution hoses from each manifold
MUST be the same length. DO NOT alter the
length of any hoses.
Removal
The oil distribution manifolds have oil hose
retainer mechanisms incorporated into the design.
Release the hose by depressing the outer ring of
the hose retaining mechanism.
Once hose is removed from the manifold, make
sure hose support is in the end of the hose.
Installation
Installation is essentially the reverse of removal.
Pay close attention when performing the following
additional tasks.
Use Replacement Oil Hose, P/N 778708, or
equivalent. Insert hose support in manifold end of
hose.
IMPORTANT: DO NOT reinsert the hose into
manifold without the hose support.
Be sure the hose is fully inserted into manifold.
The insertion depth of hose into the manifold is
5/8 in. (16 mm). Visually inspect for hose sup-
ports. Hose supports are seen through hoses.
WARNING
To prevent accidental starting while ser-
vicing, disconnect the battery cables at
the battery.
