from the vehicle. Place the engine/transmission

pan, or damage will occur. DO NOT allow the

occur.

capscrews (1) securing the transmission mount (2)

to the transmission.

capscrews (3) securing the two engine mounts (4) to

the engine.

7.10.2 Engine Disassembly, Inspection and

Service

Engine disassembly, internal inspection, service, repair

and assembly procedures are covered in the Cummins

service manual. Several special engine service tools are

required to properly service the Cummins engine.

Contact the local Cummins Service Distributor for further

information.

Note: If the engine is being replaced, and depending

upon who you purchase the new engine from, and the

configuration of your replacement engine, there may be

external components that will be required to be

transferred from the original engine to the replacement

engine. Refer to the appropriate Cummins user manual

for detailed procedures that cover the transfer of original

engine components to the replacement engine.

IMPORTANT: When re-installing the air conditioning

compressor kit to the new engine, make sure to check

the belt tension midway (5) between the fan pulley (6)

and the pulley on the compressor (7). Deflection should

be 3/16" (4,8 mm) with an applied force of 5-1/2 lb.

(2,5 kg).

IMPORTANT: When the engine is re-installed into the

vehicle, the air conditioning hoses (8 and 9) need to be

re-installed to the air conditioning compressor (10). This

procedure must be completed by an authorized air

conditioning service technician.
