TRUCK SERVICE MANUAL
ENGINE
2. Insert nozzles in block and secure. Using a
screwdriver adapter torque slotted screw to 5 to 8 ft. lb.
[0.7 to 1.1 kg m] . Torque Hex Head capscrews to 16 to
21 ft. lb. [2.2 to 2.9 kg mi.
Note:
Identification numbers stamped on the mounting
flange of oil spray nozzles are:
No. 5 FFC Series
Engines, No. 1 all others.
Remove Engine From Stand
1. Attach lifting arrangement and remove engine from
stand; mount front and rear supports to engine.
2. Remove engine stand support plates from water
header and replace with proper gaskets and cover
plates.
Oil Gauge Bracket
Install oil bayonet gauge bracket, using new gaskets.
Water Manifold And Thermostat Housing
1.
With "O" ring on water manifold connection, slip
connection into manifold. Grease new water manifold
and thermostat housing sealing rings and place rings in
cylinder heads; position and secure water manifolds to
cylinder head.
2.
Position and secure assembled thermostat housing to
front section of water manifold and install water
crossover, if used.
Exhaust Manifold
1.
Assemble sections of exhaust manifold and install
new steel exhaust manifold gaskets. Side of gasket
marked "OUT" must be installed outward or next to
manifold.
2.
Coat capscrew threads with anti-seize compound. On
turbocharged engines, if heat shield is used, install
special
capscrews
with
threaded
heads.
These
capscrews are used to mount both heat shield and
manifold.
3. Torque mounting capscrews to 25 ft-lb. [3.5 kg m]
Bend lockplate tangs up against capscrew heads. When
washers or lockplates are not used, increase torque to 40
ft-lb. [5.5 kg m] and install heat shield if used.
Thermostat Housing By-Pass Connection
Water Pump Mounted Oil Filter Remove by-pass
connection from thermostat housing, insert transfer tube
into oil filter housing. Position and secure by-pass
connection to thermostat housing.
Compressor Water Lines
Install water supply and drain lines to compressor,
cylinder block and water by-pass connections. Tighten
just enough to bring brass sleeves snugly against nuts;
this will compress rubber grommets and provide a
positive seal.
Lubricating Oil Cooler/Filter
1. Install water pump to thermostat housing by-pass tube.
Secure with hose clamps.
2. Install water inlet support bracket to cylinder block.
Start capscrews with lockwasher into block, do not
tighten.
Position water inlet assembly to water pump and
support bracket. Torque water inlet to water pump
capscrews to 30 ft-lb. [4.1 kg m].
3. Tighten support bracket to block and bracket to inlet
housing capscrews. Install water header cover plate.
4. Coat "O" rings with clean lubricating oil, position on
water transfer tube. Be sure "O" rings are not twisted.
Position water transfer tube in water header cover.
5. Install oil cooler to block bracket. Do not tighten
capscrew. Position oil cooler assembly to block and
transfer tube. Torque cooler support, bracket to housing,
and bracket to block capscrews to 30 ft-lb. [4.1 kg ml .
Install water return to thermostat housing tube (FFC
Series).
6.
Using new sealing "O" ring and filter element, position
oil filter can to oil cooler housing. Torque center bolt to 25
to 35 ft-lb. [3.5 to 4.8 kg m] .
Generator Or Alternator
1. Secure generator or alternator mounting bracket to
cylinder block. Position hardened steel washers or
spacers as needed between alternator or generator and
mounting bracket.
Note:
Do not use lockwashers or sott steel washers
when securing generator or alternator to bracket or
adjusting link.
2. Check capscrew size and torque mounting capscrews
to values in Table 14-6.

securing adjusting link to alternator, do not tighten. Install
belt(s), pry unit away from block to tighten belt(s) to
operation tension. Torque capscrews to values in Table
14-7.
