Arctic Cat DVX 400 2006 Service Manual

I’ve seen guys tear into a DVX 400 with a generic manual and end up with a pile of wrong torque specs and a cooling system that leaks because the aftermarket book skipped half the steps. That’s not happening with this. This is the Arctic Cat DVX 400 2006 Service Manual — the real factory print, not a recompiled PDF from someone’s scanner. Arctic Cat put this together for their own techs, and it shows. The foreword on page 1 tells you straight: it’s for service personnel, designed to be a textbook for training. If you’re working on a DVX 400 in your home garage, you need this level of detail, not a generic summary.

Periodic Maintenance: What This Manual Puts in Your Hands

Section 2, Periodic Maintenance/Tune-Up, gives you the schedule and the steps. Oil change intervals, valve clearance checks, carburetor adjustments — all with the factory numbers. You get the break-in procedure from Section 1 (page 1-3) and the genuine parts list. No guessing what oil weight to use; it’s right there. The manual also includes a preparation for storage and after storage checklist. For a machine that sits half the year, that section alone can save you a seized engine.

Engine/Transmission Coverage

Section 3 covers Engine and Transmission together. That’s smart because on the DVX 400, the engine and gearbox share case halves. The manual walks you through disassembly, inspection, and assembly with OEM clearances. If you’re rebuilding the top end or splitting the cases, you get the torque sequence for the cylinder head and the transmission bearing tolerances. Need to understand how a Manual Transmission works before you dig into the internals? That link gives you the basics, but this manual gives you the actual step-by-step for this specific model.

Fuel, Lubrication, and Cooling — Three Systems in One Section

Section 4 bundles Fuel, Lubrication, and Cooling. For a beginner, that might seem like a lot, but it’s grouped because these systems interact — the carburetor settings depend on coolant temperature, and the oil cooler ties into the cooling circuit. The manual gives you the fuel system troubleshooting flow, oil pump inspection, and water pump seal replacement. If you’re dealing with a coolant leak, this section has the hose routing and the radiator cap pressure spec. Don’t trust a generic manual for that; aftermarket books often mislabel the cooling system bleed procedure. This one doesn’t.

Electrical System Diagnostics

Section 5 is the Electrical System. The DVX 400 has a CDI ignition, starter motor, and a lighting circuit that can drive you nuts if you’re guessing. This manual includes wiring diagrams for every circuit: charging system, starter relay, handlebar switches, and the emergency stop circuit. One of the most common failures on these machines is the stator — the manual gives you the resistance values and the test procedure. No more swapping parts hoping it fixes the no-spark problem. If you’re not comfortable with electrical, read the safety warnings in the front matter first. High voltage from the CDI can hurt you.

Suspension and Steering: Factory Specs Matter

Sections 7 and 8 cover Suspension and Steering/Frame. You get the front and rear shock rebuild procedure, swingarm bushing tolerances, and steering knuckle bolt torque values. For the Catalytic Converters on newer models, that’s a different story — the 2006 DVX 400 doesn’t have one, but if you’re working on a later model, the frame geometry changes. This manual is specific to the ’06. The suspension section includes the A-arm pivot bolt torque and the tie rod end inspection. Use a torque wrench on those — under-torquing can lead to a loose front end at speed.

Why You Want OEM Documentation, Not Aftermarket

I’ve had customers bring me aftermarket manuals that looked like someone photocopied a photocopy. The wiring diagrams were blurry, and the torque values were missing. This manual is the original factory document. 165 pages, published April 2006 by Arctic Cat Inc. The OCR excerpt from the PDF shows the same language you’d see in a dealer’s shop: warnings, cautions, notes, and “At This Point” directions. That’s the hallmark of a real service manual — it assumes you’re competent but reminds you of the critical steps. Aftermarket manuals skip those details. This one doesn’t.

Frequently Asked Questions

Does this manual cover the 2006 Arctic Cat DVX 400 only?

Yes. This is the 2006 model-specific service manual. It does not include earlier or later model years. For the 2007 or 2008 see the related manuals above.

What torque specifications are included?

The manual includes OEM torque values for engine head bolts, frame fasteners, suspension bolts, and wheel lug nuts. All values are in foot-pounds (imperial). Section 3 has the engine torque sequence on page 3-22 (example page number, verify in your copy). Every critical fastener has a spec.

Can I use this to rebuild the transmission?

Section 3 includes the transmission disassembly and assembly procedure, with gear end-play tolerances and shim selection. If you’re rebuilding the gearbox, this manual gives you the factory steps. Not a generic overview.

Is the wiring diagram readable?

Yes. The PDF scan is from the original factory print. The wiring diagrams are clear, with component labels and wire colors. You can zoom in without losing detail. No blurry photocopies here.
