Authorized 5-ton truck tractors arc the M52A2, M818,
M931, M931A1, M932, and M932A1. When driving on
hard surface highways only, the 10-ton military-adapted

also authorized. Construction and basic configuration of
the M967, M967A1, M969, M969A1, M970, and M970A1
are the same except for dispensing equipment, new bogie,
braking system, and functional use.
b. Common Operations.
All six models, M967,
M967A1, M969, M969A1, M970, and M970A1 can be
loaded through the bottom or through the top fill opening.
The 4-cylinder diesel engine and pump assembly provide
self-load/unload capability.
c. Construction.
The trailer has a stainless steel,
single compartment tank of 5000 gallon capacity, plus 3%
capacity for product expansion. The chassis is constructed
of welded steel and is equipped with full floating tandem
axles and manually operated landing gear.
d. Common Equipment.
Each model is equipped with
pressure and vacuum vents, hose troughs, sealed
manhole, calibrated gage, bulk fuel hoses, portable
grounding rod, static reel, and spare tire. A ladder is
provided at the front of the M967, M969, and M970, and at
the rear of the M967A1, M969A1, and M970A1
semitrailers for access to the top manhole. A vapor
recovery system, required in certain ecological areas, can
be installed on all models (para 1-9).
