All 116 pages of this Case IH DHX182–DHX362 Series Repair Manual (OEM #87032609) focus on one thing: getting your draper header back to factory condition, whether you're running a DHX182, DHX212, DHX252, DHX302, or DHX362. Inside, you get hydraulic schematics covering the full header drive system, flow divider, and manifold block, plus wiring diagrams for the electrical system, sickle drive speed sensor, and remote reel speed drive. Open to the attachments section and you'll find step-by-step knife drive and cutting system procedures, connector bar assembly, and main draper deck service. Set knife relief pressure to 172.5–193.2 bar (2500–2800 psi), torque the knife head block cap screws to 55.5 N·m (41 ft. lbs.), and confirm connector bar section bolts at 12–17 N·m before buttoning anything up. Your header is down and every hour costs you. Grab the factory numbers, not a forum guess. Bookmarked by section; search any spec by keyword and pull it up right at the machine.

Case IH DHX182–DHX362 Series Common Problems This Manual Covers
Case IH DHX-series draper header complete loss of lift, header won't raise p. 61
Check oil level at the reservoir sight glass first; a tilted header can show falsely low. Confirm the header is on level ground before filling. Connect a pressure gauge and verify operating pressure reaches 138 bar (2000 psi), with relief opening at 172.5-193.2 bar (2500-2800 psi) per page 20. The hydraulic troubleshooting procedures on page 61 walk through low-pressure diagnosis step by step.
Manual Section: Hydraulic System TroubleshootingKnife bar runs rough with excessive vibration, uneven cut across the header p. 84
Inspect knife sections and guards for bent or missing pieces; these cause harmonic imbalance across the bar. Torque knife head block cap screws to 55.5 N·m (41 ft. lbs.) per page 84 and connector bar bolts to 12-17 N·m (8.5-12.5 ft. lbs.). If vibration persists, pull the center knife drive gear set; page 82 notes it is not field-serviceable, so return to dealer.
Manual Section: Knife Drive TroubleshootingDraper canvas belt slipping out of track, crops backing up at the deck p. 98
Check the fixed idler plate mounting nut; if loose, torque to 87 N·m (64 ft. lbs.) per page 98. Clear crop residue from the deck rollers and inspect the belt for glazing from past slippage. Verify the canvas hydraulic circuit has adequate flow by checking system pressure against the 138 bar (2000 psi) operating spec on page 20.
Manual Section: Canvas System TroubleshootingReel drifts down on its own or moves erratically after setting height p. 60
Inspect reel lift cylinders for external oil seepage. Verify each cylinder collapses to 457 mm (18 in.) and extends to 711 mm (28 in.) per page 60. Bleed air from the system using the troubleshooting steps starting on page 61. If hardware was recently removed, torque the master cylinder nut to 163 N·m (120 ft. lbs.) per page 71.
Manual Section: Reel Lift System TroubleshootingKnife drive stalling or throwing a KD-03 error, sickle won't maintain speed p. 78
Measure the gap between the sickle drive speed sensor and pulse wheel; adjust to 0.762-1.52 mm (0.30-0.60 in.) as shown on page 78. A gap outside this range triggers KD-03. Clean debris from the sensor face and teeth. If the fault persists, check hydraulic knife relief pressure against the 172.5-193.2 bar (2500-2800 psi) spec on page 39.
Manual Section: ElectricalHeader digging into soil on one pass, bouncing off the ground on the next p. 83
Adjust the turnbuckle on the float support arm to correct header-to-ground pressure. Verify the float indicator reads the correct position before cutting (0 for maximum float, 4 for maximum down-pressure). If the issue persists, measure motor support bracket bolt torque; it should be 183 N·m (135 ft. lbs.) per page 83. Loose brackets shift the float baseline unpredictably.
Manual Section: Draper Decks TroubleshootingFrequently Asked Questions
What are the torque specs for draper header cutterbar bolts?
The socket head cap screws on the knife head block, which is part of the cutter bar assembly, should be torqued to 55.5 N⋅m (41 ft. lbs.) during installation. It is recommended to apply a small amount of thread lock solution to the threads before installation.
