correct clearance at body hinge pins (21) and body
guides.
CLEANING HEATED BODY
Note: Optional exhaust heating of the body is
available for dumping of sticky or frozen materials.
WARNINGS
To prevent personal injury and property
damage, be sure lifting equipment is properly
secured and of adequate capacity to do the job
safely.
Oxygen and oil should never be blown
into the body passages in an attempt to burn
out the carbon deposits, as the combination of
oxygen and oil forms a highly explosive
mixture.
It is necessary to periodically clean out the carbon
deposits in the body heating passages which restrict
the flow of exhaust gases. This reduces the engine
efficiency and prevents the body from being heated.
Occasionally the carbon deposits are ignited by
spontaneous combustion or by heat from the exhaust
4
gases. The resulting fire in the heating passages is
helpful in that it burns away some of the carbon and
helps keep the body passages open. However, the fire
should be allowed to burn itself out and should not be
encouraged by pouring fuel into the passages.
If excessive exhaust back pressure develops, another
method of cleaning out the body passages is to
remove the heat channel plates and scrape the carbon
from the heating passages.
To remove the heat channel plates, burn out the weld
around them and lift out from the body assembly with
suitable lifting equipment.
Note: Prior to welding on the vehicle, follow the
procedures outlined for 'Welding' in Section 100-0010,
CHASSIS, HOOD AND FENDERS.
After the heating passages are thoroughly cleaned,
replace the heat channel plates and weld to sides and
bottom of the body assembly.
MAINTENANCE
Lubricate body hinge pins and body hoist cylinder pins
at the intervals stated and with lubricant specified in
Section 300-0020, LUBRICATION SYSTEM.
