C02018 6/02 Power Module C2-5
NOTE: Subframe rollers are supplied in the truck tool
group and can be installed in the storage position after
use, as shown in Figure 2-5.
18. Reposition hoist to front subframe lifting points (8,
Figure 2-4). Raise the engine subframe until the
engine is on a level plane. Remove the safety
chain.
The engine, alternator, radiator and subframe
weigh approximately 36,950 lbs. (16 760 kg). Make
sure the lifting device used is of an adequate
capacity.
19. Roll the power module forward sufficiently so that
adequate clearance is provided for the lifting
device to be attached to the engine/alternator cra-
dle structure and front subframe lifting points.
Place stands or block under front of subframe and
lower hoist until front of subframe is supported.
Install safety chain to prevent subframe from roll-
ing.
20. Attach lifting device to hoist and attach to engine/
alternator cradle structure and front subframe lift-
ing points as shown in Figure 2-6. Remove safety
chain.
21. Raise the power module slightly to determine if
module is on an even plane. Move the power
module straight out of truck to a clean work area
for disassembly.
For further disassembly of the engine, alternator, and
radiator, refer to the appropriate section of this manual.
Installation

subframe.
3. Check the subframe rollers making sure they roll
freely and are in the “roll-out” position. (Figure 2-
5).
4. Attach a lifting device to engine/alternator cradle
structure and front subframe lifting points. (Figure
2-6)
The complete power module weighs approximately
