CJ2A Operation and Care Manual -- Proper Maintenance (part 2 -- Engine Fails to Start, Oil System) ENGINE FAILS TO START Should the engine suddenly stop or fail to start, check the cause as follows.
ENGINE MOUNTINGS The rubber engine mountings, which are attached to the frame side rail brackets and to the support plate, prevent fore-and-aft motion of the engine, yet allow free sidewise and vertical oscillation which neutralizes vibration at the source.
FLOATING OIL INTAKE The floating oil intake (No. 28, Fig. 2) is attached to the crankcase with two screws. The construction of the float and screen cause it to remain on top of the oil, preventing the circulation of water and dirt. Once each year remove the float, screen and tube and clean thoroughly with a suitable cleaning fluid.
