Sample text

If the engine overspeeds by more than 5%, the propeller is undersized. Once you have determined the inclination angle at which the engine will be installed, construct the bed, which should have as large a footprint as hull construction permits. Leave room around the engine for servicing and, if possible, arrange matters so that the engine can be removed without structural alterations to the vessel. There must also be sufficient clearance between the flywheel cover/transmission and hull for compression of the flexible motor mounts.

Blue smoke under acceleration after prolonged period at idle. Smoke may disappear under steady throttle. Persistent blue smoke at all speeds, loads and operating temperatures. Light blue or whitish smoke at high speed under light load. Pungent odor. Probable cause Remedial action Injector pump timing retarded. Set timing. Leaking injector(s). Repair/replace injector(s). Leaking valve seals. Replace seals, check valve guides/stems. Worn rings/cylinders. Overhaul/rebuild engine. Over-cooling. Replace thermostat.

And, in practice, frame members adjacent to the transmission mount bend. Courtesy Caterpillar Inc. On many applications the transmission cantilevers off the engine block without much additional support. The bending moment imposed by the overhung load on the flywheel housing should be calculated and compared against factory specs for the engine. Figure 3-1 illustrates the calculation for a transmission that receives some additional support at the rear with a third mount. The third mount should have a vertical rate (lb/in.
