Case IH Farmall 80N to 110N and 80V to 110V Common Problems This Manual Covers
Clutch slips
If the disks are worn, check them against the clutch data, replace any part worn up to or over the limit, then adjust the levers and clutch control linkage. Replace a distorted or damaged Belleville spring disk. If oil or grease is on the friction lining, replace the discs, then find and stop the source of the lubricant. On the LUK 11"/11" clutch, the driven plate should measure 9.6 to 10.4 mm (0.37795 to 0.4094 in).
Manual Section: Clutch troubleshooting p. 335The lift does not raise
Go through the Rear Three-Point Hitch troubleshooting list in order. A clogged oil filter is the cheapest fix, so change the filter first. Next, check whether the control valve is locked in the drain position and release it. If both of those are fine, the hydraulic pump is faulty and needs an overhaul or replacement.
Manual Section: Rear three-point hitch troubleshooting p. 1082Steering wheel excessively stiff
The steering hydraulic control troubleshooting gives three causes. A faulty hydraulic pump needs repair. A pressure relief valve that is set wrong needs to be calibrated correctly. If foreign bodies have jammed the relief valve or are holding it open, clear them out and clean the filter.
Manual Section: Steering: hydraulic control components troubleshooting p. 1183Brake pedal stroke too long
If there is air in the brake circuit, bleed it. Replace the brake control pumps if they are worn. If the control pipes leak, find and fix the cause of the leak. Service brake working pressure is 17.6 bar (255 psi), and brake pedal adjustment is covered in the same section.
Manual Section: Hydraulic service brakes troubleshooting p. 800Frequently Asked Questions
