The CASE 821E Tier 3 wheel loader is a 152 hp machine built for aggregate yards, quarries, and construction sites demanding high cycle rates under load. Keeping it productive means knowing exactly what the hydraulic load-sensing circuit expects, what the ZF transmission service intervals require, and where the torque converter stalls during full-load testing. The official CNH service manual gives you all of that.
Manual Reference: 84299244 (Revised December 2009)
The 821E Tier 3 service manual (CNH part number 84299244, replacing 87364100) was issued September 2006 and revised December 2009. It is divided into discrete sections by system:
- Section 1001 — General Torque Specifications: Complete decimal and metric fastener torque charts, plus steel hydraulic fitting torques for JIC, ORFS, and BSPP connections. These apply shop-wide, not just to the 821E.
- Section 1002 — Engine (FPT 6-cylinder Tier 3): Valve clearance (intake 0.30 mm / exhaust 0.50 mm), injection timing, and belt tension specifications. Air filter restriction service limit documented for both naturally aspirated and turbocharged variants.
- Section 1003 — Transmission (ZF 4WG-210): The 4-speed powershift ZF unit used in the 821E requires a specific charge pressure test procedure. Manual documents test adapter locations, correct charge pressure range (12-18 bar), and the full clutch pack clearance specification for each forward and reverse clutch.
- Section 1004 — Axles: Front and rear Dana axles — differential carrier bearing preload, pinion gear backlash (0.20-0.35 mm), and wet disc brake adjustment procedure with the tool required to measure disc stack height.
- Section 1006 — Hydraulics (Load-Sensing System): The 821E runs a variable-displacement load-sensing hydraulic system. The manual documents the LUDV (Load Sensing with Pressure Compensated Flow Distribution) valve adjustment, main relief setting (240 bar / 3,480 psi), tilt cylinder cushion valve adjustment, and flow test procedure using Case tool CAS-10163.

- Transmission charge pressure: 12-18 bar at operating temperature
- Differential pinion backlash: 0.20-0.35 mm
- Engine valve clearance (cold): Intake 0.30 mm / Exhaust 0.50 mm

Frequently Asked Questions
Which ZF transmission fluid does the 821E use?
The manual specifies UTTO (Universal Tractor Transmission Oil) meeting Case CNH specification MS-1210, or equivalent meeting Allison C-4 / ZF TE-ML 03D specifications. Capacity: approximately 38 L with filter change.
Does the collection include Tier 4 Final models?
Yes. The F-series and G-series manuals cover Tier 4 Final variants of the 521F, 621F, 721F, 821F, 921F, 1021F, and 1121F, including the DPF regeneration procedure and DEF system service intervals.
Are the NH W-series manuals the same as the Case manuals?
The machines share platforms but the manuals are separate PDFs. The NH W-series manuals include NH-specific electrical connector locations, NH part numbers, and the NH-branded operator procedures that differ from Case documentation.
