Part of the Case IH Repair Manuals.
An hour from now you could be bleeding brakes or adjusting rear hitch linkage with this Case IH Farmall 30B, Farmall 35B service manual PDF open beside you, all 693 pages of the factory tractor book, OEM 84542385, covering both models. Wiring diagrams trace the lighting and electrical power circuits pin by pin, while hydraulic schematics map the open center remote valve and the steering circuit. The transmission and PTO section fills roughly a third of the book, taking the hydrostatic drive, power coupling clutch, and rear and middle PTO from teardown to final checks. Verify the relief valve at 16671 kPa (2418 psi), then pull the wheel disc hardware to between 176 and 196 N·m, front and rear. Every afternoon the tractor sits is a field that stays uncut. Pay once for this bookmarked, text searchable file and it belongs to you for the life of the machine.

Case IH Farmall 30B, Farmall 35B Common Problems This Manual Covers
Case IH Farmall 35B hydraulics weak under load, loader slow, three-point hitch barely lifts
Test the pump with a flow meter before condemning it. Warm the oil, tee the meter into the pressure line, and load the circuit to 13100 - 13790 kPa (1900 - 2000 psi) per the efficiency test on page 62. A healthy Farmall 35B still delivers 26 l/min (6.9 US gpm) under that load; less means replace the pump.
Manual Section: Hydraulic, Pneumatic, Electrical, Electronic Systems p. 62Implement settles under load or lift arms cycle up and down with lever in position hold
Check the troubleshooting chart before pulling the rockshaft; it separates cylinder leakage from control valve wear and relief faults. Verify system pressure against the 16671 kPa (2418 psi) relief setting listed on page 33. If pressure holds and the hitch still settles, plan on cylinder seals rather than the pump.
Manual Section: Primary Hydraulic Power System TroubleshootingHydraulic oil overheats during long mowing or loader sessions, breather smells hot
Check oil level and condition first, then work the overheating branch of the chart. Test relief pressure next: a relief set low dumps the whole pump flow across the valve and cooks the oil. Each quarter turn of the adjuster moves the setting roughly 690 kPa (100 psi) per the note on page 57.
Manual Section: Primary Hydraulic Power System TroubleshootingHydraulic hoses seeping at the fittings, oil film and drips on lines after loader work
Clean the fittings, run the tractor, and trace each leak to its source before breaking connections. Reseal NPT joints and torque per page 24: 22 N·m (16 lb ft) for 3/8 inch pipe thread, 41 N·m (30 lb ft) for 1/2 inch. Replace any hose showing a cracked or oil soaked cover before it lets go in the field.
Manual Section: Introduction p. 24Front end clunks and shimmies with a loaded bucket, wheel bolts keep working loose
Torque the front wheel bolts to 176 - 196 N·m (130 - 145 lb ft), the spec on page 34, and recheck them after the first hour of loaded work. Inspect bolt holes for elongation while the wheel is off; a wallowed disc will not stay tight. Snug the front axle M8 hardware to 26.5 N·m (19.5 lb ft) from page 482.
