An engine mounting assembly includes a pair of rear engine mounting bracket assemblies having offset mounting surfaces, an engine flywheel housing having complementary mounting surfaces, and a front mounting bracket which together provide a three-point mounting structure resulting in a significantly lowered mounting of the engine on a forward control bus chassis. The front mounting bracket includes a single point, vibration-isolated, engine mount to a lowered frame crossmember to provide vibration isolation in any direction while the rear brackets provide vertical and fore-and-aft vibration isolation. The front mounting bracket further includes a lower mount for supporting a vehicle radiator while upper stabilizing rods connect the upper portion of the radiator to the upper portion of the engine to stabilize the desired vertical position of the radiator perpendicular to the engine fan axis.

Forward control bus chassis with low engine mounting assembly

An anti-slip step having a plate member providing a tread surface portion and having an integrally formed down-turned vertical edge extending along a side, the intersection between the tread surface portion and the vertical edge being a curved surface blending into both the tread surface portion and the vertical edge. A plurality of discrete raised tabs are integrally formed as a continuation of the vertical edge and project above the curved surface. A plurality of discrete vertical apertures are open through the plate and disposed in the tread surface portion adjoining the rear and sides of each of the raised tabs. The area of an aperture is substantially larger than the vertical surface area of the respective tabs.
