REPAIR INSTRUCTIONS
ENGINE INSTALLATION
General Instructions
Engine installation details vary from vehicle to
vehicle. The following procedure provides
general installation guidelines for MACK
E-Tech™ engines.
Before beginning, make sure all equipment has
been inspected for safety and is available for use.
Place the vehicle on a flat, level surface. Make
sure the area has ample work space.
Torsional idler-gear assemblies are available for
servicing both 1:1 and 0.7:1 ratio Flywheel Power
Take-Off (FWPTO) units in E-Tech™ engines
equipped with a T200 series transmission and
FWPTO. These assemblies feature a two-piece
idler gear and torsion spring.
The torsional idler-gear assembly reduces spline
wear on the FWPTO input (drive) gear. If the unit
is removed for any reason:
r Inspect the input gear splines for excessive
wear.
r If the splines show excessive wear,
disassemble the FWPTO far enough to gain
access to the idler-gear assembly. Refer to
MACK Service Manual 10-901,
Flywheel
Power Take-Off
.
Engine Installation into Vehicle
Obtain assistance when installing the engine. Be
sure to watch for obstructions such as engine or
chassis components, brackets, clamps or other
components that may interfere with engine
installation.
1. Align engine with the torque converter or
clutch (as applicable) and install the
transmission bell housing-to-flywheel
housing capscrews. Tighten the capscrews
to specification.
2. Install engine mount capscrews to secure
the engine to the engine mounts. Tighten the
capscrews to specification.
3. Remove transmission jack from under
transmission.
4. Install the clutch linkage and bracket-
retaining capscrews.
5. Install power steering hoses and reservoir, if
applicable.
6. Install the hood rest crossmember(s), if
applicable.
7. Install the exhaust bracket to the flywheel
housing and install exhaust clamp at the
turbocharger.
8. Install the starter. Connect wiring and
cables.
9. Install the air cleaner housing, if required.
10. Install all coolant tubes, ground straps, air
lines, fuel lines, hydraulic hoses or tubes,
throttle linkage and electrical wiring
harnesses that were removed from the
engine during removal.
On some engine models, the machined V-band
was replaced with a 3.5-inch push-on
turbocharger discharge connection that is angled
forward. The remaining models use a 3-inch
push-on connection directed 90 degrees outward
from the center line of the turbocharger. You will
need to know which turbocharger type is used on
the engine when ordering replacement parts.
11. Connect the air inlet tube between the
turbocharger and air cleaner assembly.
12. Connect the heater hoses and A/C
refrigerant lines, if applicable, where
attached at the lower dash panel behind the
engine.
13. Install the fan and fan clutch assembly.
14. Install the accessory drive belts and adjust
the belts to specification.
15. Using a lifting device, place the radiator in
position at the front of the engine.
16. Install the retaining capscrews to the lower
radiator support mounts.
