What's in it

The power train chapter covers the torque converter, the 6-forward, 3-reverse power shift transmission, the tandem drive and, for W machines, the all-wheel-drive system. Then come the moldboard, circle and tilt, the steering, the brakes and the hydraulic system, followed by the electrical system and sensors. Testing, adjusting and troubleshooting have their own chapter. Disassembly and assembly and the maintenance standards with wear limits finish the book.

The fluid charts list two engines, the S6D102E-1 and the S6D114E-1, so make sure you're reading the right column for your grader.

County road crews, contractors and grader mechanics get the most use from it. Transmission and tandem work, circle and moldboard wear, steering and brake faults and hydraulic leaks are the usual jobs.

Good to know

Most people use a book like this one section at a time. Look up the system that's giving trouble, read how it's meant to work, test it against the standard values, and only then order parts. That order saves money, because a reading that's close to spec usually points somewhere other than the part you suspected first. You can print the pages for the job and keep the PDF on a tablet for everything else.

Before you buy

If your grader is a standard (non-W) model, you can skip the all-wheel-drive sections. The rest applies the same.
