Today we had a driver accidentally bump start his engine backwards. This is not a common problem but one that everyone needs to know what to do in this situation. Typical this only happens to older mechanical Cat engines and the first indication is smoke coming out of your air cleaner and zero oil pressure.
Fortunately the driver noticed both of these indicators, shut off his engine, checked his oil, and then restarted the engine. It appears no damage was done to the engine. However I have seen the rod and main bearings welded to the crankshaft causing extensive damage to the engine. Be aware and know what to do.
