All 178 pages of this Case IH Maxxfarm 60 Service Manual (OEM #47673551) cover one tractor family: the Maxxfarm 60, U60, U55, U47, and U43, from cab separation and clutch housing teardown through transmission rebuild and rear axle overhaul. Inside: hydraulic schematics tracing the full circuit from main pump through rear lift, remote control valves, steering, and low-pressure return, plus circuit diagrams for the starter, alternator, fuel solenoid, and pre-heater. You also get page after page of torque specs, exploded views for every major subassembly, transmission fault-finding charts, and step-by-step procedures for four-wheel drive, PTO, differential lock, and brakes. Set rear differential ring gear and pinion backlash to 0.20-0.30 mm, then confirm your hydraulic pump is at 14 cc/rev before chasing a lift fault. Chasing the same problem twice costs a full day. Bookmarked and keyword-searchable; open on any device and get back to wrenching.

Case IH Maxxfarm 60 (U43–U60) Common Problems This Manual Covers
Case IH Maxxfarm 60 differential housing oil leak, transmission front plate visibly wet p. 33
Inspect the transmission front plate, input shaft, and PTO drive shaft areas to pinpoint the leak source; the troubleshooting list on page 33 identifies each common seal failure point. If the front differential housing is weeping, replace the oil seal (D45XD62X9T, per page 85). Clean the housing, refill to the correct level, and verify after two hours of operation.
Manual Section: TransmissionHydraulic lift won't raise implement, raises too slowly, or won't hold load up p. 122
Check hydraulic fluid level first, then measure the lift cylinder safety valve opening pressure: it must reach 210 kg-f/㎠ (page 122). If pressure is low, trace back through the hydraulic circuit schematic on page 108 to isolate whether the pump, control valve, or cylinder is the failure point. Purge air from the system before condemning any component.
Manual Section: Hydraulic SystemClutch slips under load or won't fully disengage when pedal is fully depressed p. 30
Measure clutch pedal free play at the pad: spec is 20~30mm (page 30). If play is within range but the clutch still slips, the 8mm single disc dry plate (page 34) is worn or contaminated and needs replacement. Remove the clutch housing and inspect the disc for glazing, oil fouling, or thickness below minimum before ordering parts.
Manual Section: TransmissionSteering requires excessive effort or front wheels wander and surge at field speeds p. 134
Bleed air from the hydraulic steering circuit first. Air is the most common culprit per the fault-finding table on page 134. If bleeding doesn't restore feel, check tie rod end play and torque the lock nuts to 5.0~5.5 Kg-f-m (page 92). Persistent wander after bleeding usually points to the steering orbitrol unit or pump.
Manual Section: Hydraulic SystemStarter motor cranks slowly or fails to turn engine over in cold conditions p. 147
Verify battery voltage before touching the starter: the rated 12V-2.2kW unit (page 147) draws heavy current and a weak battery mimics starter failure. Test the magnetic switch and brush condition using the no-load procedure on page 147. Replace brushes if worn below spec; inspect the over-running clutch and reduction gear if the motor spins but fails to crank.
Manual Section: Electrical SystemFront axle differential growls under load or pinion bearing whines at road speed p. 86
Check pinion bearing preload immediately after any front differential service: rolling torque must measure 14.5~20.0 kg-f-cm (page 86). A torque reading outside this range accelerates bearing wear and produces the characteristic growl under load. Adjust the pinion nut until rolling torque is within spec, then verify ring gear backlash before closing the housing.
Manual Section: Front AxleFrequently Asked Questions
What are the replacement specifications for Driveline Oil Seal?
The manual indicates that if the input shaft oil seal, PTO drive shaft oil seal, transmission front plate seal, or reverse idler retaining bolt oil seal are worn or damaged, they should be replaced. However, specific replacement specifications for the driveline oil seal, such as dimensions or material, are not provided.
What are the replacement specifications for Differential Pinion Bearing?
For the front differential, the manual specifies outer taper bearing #32206C.KBC, inner roller taper bearing #32207C.KBC, and taper bearing #32010XJ.KBC. During re-assembly of the rear differential pinion shaft, ensure the pinion bearing rolling torque is 10~12 kg-f-cm. If any bearings are damaged, they should be replaced.
