Need the factory book for your Case 821C Loader? This 713-page service manual (OEM Bur 7-13051) puts every Electrical, Steering, Power Train, Brakes, and Hydraulics procedure in one searchable file. You get wiring diagrams for the starter, alternator, and diagnostic center, full hydraulic schematics covering the loader control valve and cylinders, and a troubleshooting section that walks you through steering, transmission, and brake accumulator faults instead of leaving you guessing. Torque the engine support bracket bolts to 366-439 Nm, and check that the secondary hydraulic pump holds 75% efficiency before you chase a phantom leak. No more flipping through a shop-worn photocopy trying to find the oil cooler hose spec. Your 821C isn't waiting, and neither should you. Bookmarked by section, it opens on a laptop, tablet, or phone right on the shop floor.

Case 821C Common Problems This Manual Covers
Case 821C loader won't move in reverse, transmission fails to engage with 46062 fault code
Pull the 46062 code and check the electrical troubleshooting procedures for the 3-wire output speed sensor circuit. Disconnect the sensor, test wiring continuity, and inspect the connector for corrosion. Compare readings against the diagnostic test values; replace the sensor if it's out of spec, then clear the code and verify reverse engagement.
Manual Section: Electrical TroubleshootingHydraulic fluid leaking from hoses, bucket loses lifting power under load
Inspect all hydraulic hoses and lines for cracking, chafing, or weeping fittings, checking oil cooler connections first; torque those fittings to 95 to 115 Nm (70 to 85 pound-feet) per page 434. Run the pump output test in the hydraulic troubleshooting section starting . If secondary pump efficiency reads below the 75 percent spec on page 473, replace the pump.
Manual Section: Hydraulic System Troubleshooting (General)Starting fluid (ether) container appears cracked, dented, or leaking vapor during removal from bracket
Follow the safety instructions before handling the container: relieve pressure slowly, wear eye protection, and keep clear of open flame or sparks. Verify the canister seats fully in its mounting bracket and the puncture valve engages squarely so vapor can't escape. Replace any container showing corrosion, dents, or a bent puncture pin rather than forcing installation.
Manual Section: Electrical: Safety InstructionsEngine won't start or turns over slowly in cold weather below freezing
Load-test each battery against the 800 amperes cold cranking spec at -17°C (0°F) on page 57, and clean any corroded terminals. Check starter and solenoid connections against the wiring diagram. Run the stall test on page 38 and confirm converter stall speed falls between 1885 and 2065 rpm before condemning the starter.
Manual Section: Electrical p. 57Parking brake won't hold or fails the adjustment test after warm up
Run the parking brake check and adjustment sequence with the accumulator fully charged. Verify nitrogen precharge sits at 55 to 57 bar (800 to 825 psi) per page 400 before adjusting the brake actuator. If pedal feel stays spongy after adjustment, bleed the hydraulic brake system per the troubleshooting steps starting on page 398.
Manual Section: Parking Brake Adjustment/TestSteering feels heavy, stiff, or wanders at low engine RPM during turns
Test the steering relief valve against the 184 to 193 bar (2665 to 2800 psi) spec on page 225. Check pump output and priority valve function in the steering troubleshooting section, and inspect cylinder seals for internal bypass. Torque any loosened fittings to spec and retest relief pressure before returning the machine to service.
Manual Section: Steering p. 225Frequently Asked Questions
How do I reset the fault code on a Case 821C?
To remove diagnostic codes from locations 071 through 090, press the program/reset switch to program, then the up/down count switch until the display reads 055. Place the program/reset switch in the OFF position, then press the up/down count switch until the display reads 21, and finally press the program/reset switch to reset. This will clear the codes unless the condition still exists. p. 184
What are the torque specifications for the Case 821C engine?
For the Case 821C, engine-related torque specifications include: bolts fastening the engine support bracket to the rear frame at 366 to 439 Nm (270 to 324 pound-feet), Allen head screws for flex plates at 41 to 46 Nm (360 to 408 pound-inches), and cap screws for the transmission to flywheel housing at 54 to 60 Nm (480 to 528 pound-inches). p. 24
What does error code 46062 mean on a Case 821C and how to reset it?
Error code 46062 indicates "Output speed zero, does not match other speeds." To address this, check the sensor signal, the sensor gap, and the cable from the TCU to the sensor. This fault code is reset automatically after power up of the TCU. p. 196
What is the engine oil capacity with filter change for the Case 821C Loader?
The engine oil capacity with filter change for the Case 821C Loader is 20.8 litres (22 U.S. quarts). The recommended oil type is Case No. 1 Engine Oil. p. 14
