This week I was reading about the type of crown gear uses in the differential of the international truck that I took apart. The type of gear set used is a hypoid gear. In this type of gear set the pinion gear drives the crown gear from below the center of the crown gear. This gives hypoid gears a greater torque capacity. These gears drive forward on the convex side of the gear teeth. The characteristics of a hypoid gear allows it to run quieter and makes it stronger.

Alignment

This week I learned how to set the alignment on a truck using "The common man's guide". The first step is to set the toe. When doing this you should drive the truck forward in a straight line so that it is sitting how it would be driving down the road. Then you check the toe by placing a bar on each wheel and taking a measurement from bar to bar. The measurement between the front wheels should be 1/16" les than the rear so that you have 1/16" toe in. The toe can adjusted by turning the bar that connects the tie rods.

This week I pulled a diffential out if an international truck. I pulled it out because it was making grinding noises and wasn't sending power to that different.
