A soil stabilizer that drops charge pressure mid-pass does not care that the dealer is closed. Your answer is the Cmi RS-650 service manual PDF: 278 pages of factory data, filed under OEM ID AO 8058, covering the road reclaimer from primary power system through cutter gear reducer rebuild to final assembly. Electrical and hydraulic schematics trace each circuit from pump to servo valve, and the troubleshooting section works through ground drive, travel control, fan drive, and microcontroller faults in factory order. Set auxiliary system pressure at 2000 psi, hold ground drive charge between 320 and 360 psi, and torque M12 fasteners to 95 N-m plus or minus 15. One missing pressure number can park the machine all afternoon. Bookmarked and text-searchable, this PDF hands you that figure in seconds; download it and keep a copy with the machine.

Cmi RS-650 Common Problems This Manual Covers
CMI RS-650 loses ground drive under load, machine will not move or creeps in one direction only
Check ground drive charge pressure first; spec is 320 to 360 psi on page 16. If it reads low, inspect the charge pressure relief valve, then replace the cartridge and torque the hex plug to 68 Nm (50 lb ft). Verify system pressure reaches the 4640 psi limiter setting before condemning a pump.
Manual Section: Ground Drive System p. 172Cutter drum stops cutting mid-pass, belt slips and drum stalls in hard material
Confirm cutter belt tensioner pressure holds 4500 psi per the settings on page 16. Inspect belts for glazing and the cutter clutch for slippage, following the drive assembly procedures starting on page 193. Replace worn cutter teeth and cracked tooth holders; weld replacement holders with 3.2 mm to 4 mm rod per page 225.
Manual Section: Cutter System p. 193Hydraulic system runs hot, sluggish travel response and low charge pressure after warmup
Clean debris from the radiator and oil cooler cores; removal procedures are on page 167. Verify auxiliary system pressure at 2000 psi and ground drive charge pressure at 320 to 360 psi against the settings on page 16. Check for high vacuum at the pump inlet and replace any collapsed suction hose.
Manual Section: Auxiliary System p. 167Engine cranks too slowly or will not crank at all, batteries go dead overnight on site
Test batteries with a hydrometer and load tester, then work through the cranking troubleshooting chart on page 131. Check alternator output against the 60 A rating listed on page 105; a weak alternator never fully recharges the batteries. Clean and tighten ground cables at the frame and starter before replacing anything.
Manual Section: Primary Power System Troubleshooting p. 131Excessive vibration and harsh noise from cutter housing, drum bearings running hot at full depth
Inspect the cutter bearings and drum drive assemblies; teardown procedures start on page 193. Check the cutter transmission cooling system: the relief valve should hold 3447 kPa (500 psi) per page 117, and the system takes 17 liters (4 gallons) of oil. Replace any bearing that shows heat discoloration or roughness when rotated by hand.
Manual Section: Cutter System p. 193Frequently Asked Questions
What are the torque specifications for metric nuts and bolts on the RS-650?
The standard torque for metric nuts and bolts varies by thread size. For example, an M6 bolt requires 12 ± 4 N·m (9 ± 3 lb. ft.), while an M36 bolt requires 2700 ± 400 N·m (2000 ± 300 lb. ft.). p. 8
How do I troubleshoot a low alternator output on the RS-650?
Low alternator output can be caused by a slipping drive belt, broken or corroded wires, a defective regulator, or internal component failures such as defective rectifier bridge diodes, grounded field coil windings, or a defective stator. p. 131
What is the recommended hydraulic system pressure for the auxiliary system on the Cmi RS-650?
For the auxiliary system, the recommended pressure setting is 2000 psi. p. 16
What is the procedure for adjusting the ground drive pump neutral?
Perform the neutral adjustment with the engine and ground drive pump running. Block the machine, install 3,450 kPa (500 psi) pressure gauges into the servo gauge ports, then loosen the neutral shaft locknut and turn the shaft until both gauge readings match. p. 146
What is the required torque for the cutter clutch air tube holding plate capscrews on the Cmi RS-650?
Torque the air tube holding plate capscrews to 497 Nm (367 lb ft). p. 114
