Abstract

An engine is disclosed having a starter clutch ring gear, and a crank case having an integral starter pinion accepting member defining a through bore, and a gear assembly having an exterior surface configured to engage a flywheel and an surface engaging the second of the shaft. A starter pinion shaft is disposed through the through bore. The integral starter pinion accepting member defines a surface coupled to an engine mount.

First claim

What is claimed is:

1. An engine mount comprising:
a cylindrical bushing member having a first pair of axially projecting flanges coupled to an exterior bearing surface;
an integrated plate member having a second pair of projecting flanges, the integrated plate member being at least partially disposed within the cylindrical bushing member; and
a support bracket having a raised lip annularly surrounding the cylindrical bushing member.

2. The engine mount according to claim 1 wherein the support bracket has a threaded pin disposed through the cylindrical bushing member which is used to couple the engine mount to a vehicle frame engaging member.

3. The engine mount according to claim 1 wherein the second pair of projecting flanges are at least partially disposed within the first pair of projecting flanges, and wherein at least one of the first or second projecting flanges are operable to be aligned with a pair of flange accepting apertures defined in a vehicle frame.

4. The engine mount according to claim 1 wherein the first pair of projecting flanges are positioned on a first surface of the cylindrical bushing member and are radially displaced between 10 and 180 degrees about a cylindrical bushing member periphery.

5. The engine mount according to claim 1 wherein the support bracket has an interface surface configured to be directly mounted to a crankcase.

6. The engine mount according to claim 1 wherein the second pair of projecting flanges are at least partially disposed within the first pair of projecting flanges, and wherein at least one of the first or second projecting flanges are aligned with a pair of flange accepting apertures defined in a vehicle frame engaging member.

7. An engine mount comprising:
a cylindrical bushing member having a first pair of projecting flanges coupled to an exterior bearing surface;
an integrated plate member having a second pair of projecting flanges, the integrated plate member being at least partially disposed within the cylindrical bushing member; and
a support bracket having a raised lip annularly surrounding the cylindrical bushing member;
wherein the cylindrical bushing member extends from a top surface to a bottom surface;
wherein the first pair of projecting flanges coupled to the exterior bearing surface extend off of the top surface.

8. The engine mount according to claim 7 wherein the cylindrical bushing member is formed of rubber.
