Mode Selection 101

You are almost finished swapping transmissions. You just put in a full shift, maybe a shift and a half swapping them. Everything seemed to go so well… Something can’t be right. There must be a hitch.

School Bus Fleet GPS Telematics

Years ago… 20 to be exact when I started working for this school bus fleet we relied on land lines and 2 way radios to get a report on break downs.

Earned My Wrenches in the Bakken

Mercedes MBE 900 Diesel Engine Repair

This repair has a long history of scenarios which ended up as a major engine repair. The head gasket on this 2008 Mercedes MBE 900 diesel engine has failed. That’s the least of possibilities.

Cold Start Mercedes Diesel Engine in a School Bus

This bus is one of our older non emission diesel engines. It’s a 2004 Mercedes MBE 900 in a Thomas HDX pusher school bus.

MaxxForce 7 Diesel Engine Air Compressor Failure

The one advantage to a belt driven air compressor is the minimal labour to change it out.

The… Continue reading MaxxForce 7 Diesel Engine Air Compressor Failure

Mercedes Diesel Engine Air Compressor Failure

This school bus with a Mercedes MBE 900 diesel engine suffered a premature air compressor failure due to dirt in the engine oil caused by a faulty air intake hose.
