Important Information:

Select model FMC-HYD-210 when pumping pressures between 60 and 100 PSI are required. In the 86 Series tractors with open center systems, the hydraulic system was not designed for continuous hydraulic demand at the remote valves. These tractors will require the Ace Pump IHK-86 kit for sprayer pump operation. Refer to Ace form 4013-A for complete installation instructions. Reference the International Harvester Service Bulletin S-3436 dated March 31, 1977.

Installation Instruction for OPEN CENTER System 1. Shut off all flow from ACE pump. 2. Install pressure gauge between pump and shut off valve. 3. Open Bypass Adjusting Screw 3 or 4 turns. 4. Set tractor throttle to speed at which you will be spraying. 5. Turn Bypass Adjusting Screw clockwise until pressure gauge on sprayer reads between 60 and 100psi. Tighten jam nut.
