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.
Claims20
An engine comprising:
- a clutch ring gear;
- a crank case having an integral starter pinion accepting member defining a through bore, the through bore having a through bore interior surface;
- a gear assembly having a first fear assembly surface configured to engage the clutch ring gear and a second gear assembly surface configured to engage a linear drive;
- and
- a starter pinion shaft disposed through the through bore, the starter pinion shaft having a first end projecting from a first side of the integral starter pinion accepting member and being configured to be coupled to a starter motor, the starter pinion shaft having a second end projecting from a second side of the integral starter pinion accepting member, the second end defining the linear drive supporting the gear assembly, the starter pinion shaft being supported by a bearing disposed between the starter pinion shaft and the through bore internal surface.
