Power Trains

The first half of the summer we have John Deere Power Trains. The classroom involves Quad-Range, Power-Quad, Power Shift and Infinitely Variable Transmissions. We also discuss power flows and repair procedures. Here are some of the lab pictures.

Graduation 2015

There were 35 students that made it to graduation this year. It has been an exciting and fun 2 years that went by in a hurry. Here are some pictures.

Nathan and Andy 8.1L

This is an 8.1L with and electronically controlled "P" pump. This is the first time this engine has been apart at school. It is an experimental engine that must have been used for endurance testing because it was dirty inside. After many trips to the wash rack and parts washer it lives again.It is good they picked this engine or they may have been upset with the instructors.

Devin and Jacob 7.6L

This is the famous "666" engine. This is the 17th year that I have seen this one run and it ran a few times before I got there. It has a bent crankshaft so it can be used as class discussion during the assembly process.

Nathan 6.8L

This engine has been around for a long time but it hasn't been apart for several years. I actually is a 414 Cu. In. engine with a rotary distributor pump. It is an experimental engine so it has a few unusual parts in it.

Jake and Joseph 7.6L

Jake and Joseph rebuilt a 7.6L engine with a mechanical inline pump. I looks like it may be getting plenty of fuel.
