TENSIONER - TIMING CHAIN
DESCRIPTION
The timing chain tensioner is a stamped steel constant tension mechanicaldesign. It is mounted to the front of the
engine, behind the timing chain drive.
OPERATION
The timing chain tension is maintained by routing the timing chain throughthe tensioner assembly. A nylon covered
spring steel arm presses on the timing chain maintaining the correct chaintension.

ENGINE - 5.9L DIESEL - SERVICE INFORMATION
DESCRIPTION
DESCRIPTION - 5.9L DIESEL
The cylinder block is constructed of cast iron. The casting is a skirted design which incorporates longitudal ribs for
superior strength and noise reduction. The block incorporates metric straight thread o-ring fittings at lubrication oil
access points. The engine is manufactured with the cylinders being a non-sleeved type cylinder. However, one
approved service method is to bore out the cylinders and add cylinder sleeves to the cylinder block.
The cylinders are numbered front to rear ; 1 to 6. The
firing order is 1–5–3–6–2–4.

DESCRIPTION - CRANKCASE BREATHER
The crankcase breather assembly is integrated into
the cylinder head cover (3) and is not serviced seper-
ately. The external fittings (2) to the breather tube and
breather drain tube are serviceable.

could reduce the pressure.
2. Oil viscosity thin, diluted or wrong
specification.2. (a) Verify the correct engine oil is being
used. (Refer to LUBRICATION &
MAINTENANCE/FLUID TYPES -
DESCRIPTION).
(b) Look for reduced viscosity from fuel
dilution.
