228. Preferred Demolition Methods
Explosives and mechanical means, either alone or in combination, are the most effective methods to employ. Listed
below are the vital parts in order of priority of demolition for each preferred method. In each case, completion of the first
two steps will render the unit inoperative. Completion of the additional steps listed will further destroy the unit.
a. Demolition by Explosives (fig. 136). Place as many of the following charges as the situation permits and detonate
them simultaneously with detonating cord and a suitable detonator.
(1) A 2-pound charge on engine flywheel case.
(2) A 4-pound charge between the first countershaft pinion and second countershaft gear and pinion.
Note. The above charges are the minimum requirement for this method.
(3) A 4-pound charge on each forward and reverse clutch assembly.
(4) A 2-pound charge between the steering lever and master clutch and gear shift levers on the control platform.
(5) A 2-pound charge between the brake pedals and sprinkler pedals on both sides of the road roller.
(6) A 2-pound charge on the hydraulic oil pump.
(7) A 2-pound charge on the engine block behind the manifold.
(8) A 1-pound charge on the engine block behind the magneto.
(9) An 8-pound charge between the steering roll swivel pin and the sprinkler mat.
(10) A 4-pound charge between the second countershaft gear and the final spur gear drive on the frame side member.
(11) A 6-pound charge against each roll in the roll path.
b. Demolition by Mechanical Means. Use sledge hammers, crowbars, picks, axes, or any other heavy tool which
may be available together with the tools normally included with the road roller to destroy the following:
(1) Transmission.
(2) First countershaft pinion, second countershaft gear, pinion, and final spur gear drive.
Note. The above steps are the minimum requirement for this method.
(3) Engine block, head, magneto, and carburetor.
(4) All control mechanisms.
(5) Hydraulic steering cylinder and hydraulic pump.
(6) Steering roll kingpin.
(7) Radiator core and tanks.
