Champion 700 Series Training Manual – Factory Specs for Motor Grader Systems

If you’re tearing into a Champion 700 Series motor grader without the factory training manual, you’re working blind. I’ve seen guys guess on counterbalance valve settings and end up with a moldboard that drops like a rock. This Champion 700 Series Training Manual is 63 pages of factory theory – not a service manual for torque values, but the key to understanding how these machines work together. Published 3/87, covers serial numbers 16224 and up. You need this on your bench if you’re diagnosing hydraulic leaks or transmission oddities.

Main Hydraulic System and Cushion Valve Function

Pages 15–18 cover the main hydraulic system, main relief valve, and cushion valve. If you don’t understand how the cushion valve interacts with the main relief, you’ll never get the blade control right. The training manual uses oil flow diagrams to show the balance. For torque specs on the valve nuts, reference the Shop Manual – this is about the theory. Without it, you’re guessing at what causes drift in the moldboard lift cylinders.

Does the Manual Cover All Wheel Drive Systems?

Yes, pages 55–56 cover the All Wheel Drive System. That system uses a hydraulic motor and clutch to drive the front wheels. The training manual walks through the theory of engagement and disengagement. If you don’t understand how the pressure switches signal the control valve, you’ll end up replacing parts that aren’t broken. I’ve seen that happen. The manual helps you trace the circuit from the pump through the solenoid valve to the front axle. It also explains the interlock with the transmission range. Without this knowledge, diagnosing an AWD that won’t engage or disengages too early becomes guesswork. The manual gives you the system integration – not torque specs, but the logic. That’s valuable. The 8400 transmission is a powershift, not a Manual Transmission, and this manual clarifies the clutch pack engagement for the AWD circuit too.

8400 Transmission: Oil Circuit Flow Paths

The 8400 transmission oil circuits are detailed on pages 27–28 for the clutch oil supply. Then pages 37–40 show eighth forward and first reverse oil circuits. The manual traces oil flow through the clutch packs and the double clutch pack assembly (pages 41–42). If you’re chasing a slipping clutch, start here. You’ll see which valves control each gear. For contrast, a Manual Transmission uses a different clutch design, but this manual focuses on the powershift. Understanding these flow paths prevents misdiagnosis of pressure drops.

3 Critical Systems for Safe Operation

Three systems that can put you in a ditch if misadjusted: the leaning wheel and toe-in (pages 7–8), the steering system (pages 9–12 for 720-760, pages 11–12 for 710/710A), and the standard brakes (pages 51–52). The training manual explains the theory behind each adjustment. Get these right by understanding the geometry, not just by feel. The lock/unlock differential (pages 45–46) is another system that requires proper system knowledge – the training manual shows how it integrates with the final drive and tandem assembly (pages 49–50).

Understand the Circle Timing and Toe-In Adjustment

Circle timing (pages 23–24) and turning the circle (pages 25–26) are covered. The manual explains the procedure for correcting drift through the circle drawbar and moldboard assembly (pages 21–22). Don’t skip this if the blade won’t hold position. The toe-in adjustment on the leaning wheel (pages 7–8) is also explained with the theory of why it matters for tire wear and straight-line tracking.

If you need coverage for other models, check the Champion 720, 710A, 780, 780A 1991 Training Manual – Factory Specs or the Champion 700 Series Grader Series III Service Training Manual. For the Series III, there’s the Champion 700 Series Grader Series III Training Manual.

Frequently Asked Questions

What serial numbers does this manual apply to?

Serial numbers 16224, 16245 and up. U.S. serial numbers 2021-2 and up.

Can I use this manual to rebuild the transmission?

No. This is a training manual designed to help you understand how the systems interact – the oil circuits, valve functions, and mechanical linkages. If you need to know the exact torque for a main relief valve nut or the clutch pack clearance, you have to reference the Champion Shop Manual. The training manual provides the big picture: for example, how the counterbalance valve controls the power tilt lock and why a worn seal causes drift. That knowledge prevents you from chasing parts you don’t need. But for actual disassembly specs, you need the shop manual.

How many pages is the manual and what year was it published?

63 pages, published March 1987.

Does this manual include torque specifications?

No, it does not. The manual explicitly says on page 2 that for torque specifications you must use the Shop Manual. The training manual is about understanding the theory and integration of the systems – like how the main relief valve and cushion valve work together in the hydraulic system, or how the lock/unlock differential engages. Without that understanding, you might misdiagnose a problem and throw parts at it. The actual torque values are not listed here. If you need them, buy the shop manual.

Stop guessing. If you want to understand how the Champion 700 Series motor grader works before you put a wrench on it, get this training manual. It’s the foundation for every system on the machine. Access the Factory Manual from AutoRepairManuals and put it on your tablet for reference during diagnostics.
