2. Subframe
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

Installation

1. Inspect the main frame guide rails. Remove any
debris which would interfere with power module
installation.
2. Clean the main frame rear support brackets.
Apply a light film of soap solution to each rubber
bushing (5, Figure 2-4) located at the rear of the
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
36,950 lbs. (16 760 kg). Make sure lifting device to
be used is of an adequate capacity.
5. Raise the power module and align the subframe
rollers within the main frame guide rails.
