Heavy Iron Overhaul: John Deere Large-Frame D-Series (EH) Hardware Service
The John Deere D-Series large-frame lineup—including the wheeled 326D, 328D, and 332D, plus the tracked 329D and 333D—sets the standard for high-capacity material handling and earthmoving. Equipped with Electro-Hydraulic (EH) joystick controls, these machines offer refined precision, yet the physical work they perform is incredibly punishing. From lifting heavy pallets to operating high-vibration mulching heads, the structural integrity of the loader arms, the wear tolerances of the undercarriage, and the sealing of the hydrostatic pumps are constantly tested. When your D-Series requires deep mechanical attention, the John Deere 326D, 328D, 329D, 332D, 333D (EH Controls) Repair Service Technical Manual (TM11439) is your definitive workshop blueprint.
Delivered for immediate digital retrieval at Manualsmarket.com, this technical publication provides the manufacturer-approved disassembly sequences, torque limits, and assembly protocols required to restore the physical strength of your loader fleet.

Mechanical Reconstruction & Drivetrain Maintenance
This technical guide focuses on the "nut-and-bolt" reality of the large-frame D-Series, providing clear instructions for heavy-duty structural and mechanical repairs.
- Tracked Undercarriage Service (329D & 333D): Precise methods for releasing track tensioner pressure, removing heavy rubber tracks, and physically unbolting planetary drive units, bottom rollers, and front idlers.
- Wheeled Final Drives (326D, 328D, 332D): Factory steps for accessing the side chain enclosures, adjusting drive chain tension, and extracting wheel hubs to press in new axle bearings and seals.
- High-Flow Hydraulic Extraction: Detailed procedures for unbolting and removing the primary hydrostatic tandem pumps from the chassis belly, along with internal teardown blueprints for the lift and tilt cylinders.
- Boom & Chassis Structural Repair: Sequential instructions for driving out large pivot pins, checking loader arm alignment, and reconstructing the front quick-tatch faceplate to original tolerances.
Who Should Add the TM11439 to Their Shop Library?
- Forestry & Mulching Contractors: Maintain your 333D mulching units by performing your own undercarriage rebuilds and hydraulic pump swaps between seasons.
- Commercial Site Grading Crews: Keep your high-capacity 332D and 328D loaders structurally sound by replacing worn bushings and axle seals in-house.
- Heavy Equipment Restoration Centers: Use verified OEM torque specs and assembly sequences to execute profitable, factory-standard overhauls of D-Series equipment for resale.
Workshop Floor FAQ for the D-Series Fleet
Does this manual explain how to remove the EH joysticks?
Yes. It covers the physical unbolting and removal of the EH control pods from the cab armrests, though electronic calibration is a diagnostic task.
Can I use this guide to rebuild the engine on my 333D?
The manual covers the complete procedure for safely extracting the engine block from the frame, disconnecting the cooling stack, and reinstalling it. Internal engine component repair may refer to specific engine-only technical manuals.
Are the wiring diagrams for the 332D included in this PDF?
No. Electrical schematics and diagnostic fault codes are found in the companion Diagnostic manual. This document is dedicated to physical hardware and mechanical repair.
Is this manual helpful for replacing a leaking boom cylinder?
Absolutely. It outlines the exact mechanical removal of the cylinder, the internal barrel disassembly, and the sequential steps for installing new seal kits.
