Challenger 670 2006 Parts Catalog – OEM Factory Manual for Combines

If you’ve ever spent a morning waiting on a part that didn’t fit because someone guessed a number from a third-party site, you know what I’m talking about. This is the original factory Challenger 670 2006 Parts Catalog – 603 pages of OEM exploded views and part numbers. No aftermarket interpretations, no reprints. Every fastener, seal, and bracket is keyed to the factory illustration. You get the same book the dealer’s parts counter uses.

Engine & Mounts: Where Most Mistakes Happen

The ENGINE section is broken into ENGINE & MOUNTS, COOLING FAN DRIVE, AIR INTAKE & EXHAUST, and MAIN ENGINE DRIVES. Each subsection has its own exploded diagram with item numbers matching the parts list on the facing page. If you need a fan hub or a mount isolator, you’ll find the exact part number – not a cross-reference that may or may not work. Common hardware like bolts and lockwashers are listed indented beneath the item they attach to, so you don’t accidentally order a separate bolt kit. That’s detail you only get from an OEM Parts Catalog, not a generic service manual.

Cooling System – Radiator Slinger, Rotary Screen, Fuel Lines

Aftermarket manuals often skim over the cooling stack. This catalog dedicates multiple sections to the COOLING SYSTEM, RADIATOR SLINGER, and ROTARY SCREEN. The rotary screen assembly alone has its own page with every mesh panel, drive roller, and tensioner listed. Fuel lines are grouped separately under FUEL LINES – again, with routing diagrams and part numbers for each hose and clamp. If you’re troubleshooting an overheat or replacing a leaking line, you need this level of specificity to order the right piece the first time.

CAB Electrical: HVAC, Harnesses, and the 150-Amp Alternator

Inside the CAB section you get FRAME & MOUNTING, WINDOWS AND DOORS, INTERIOR COVERINGS & TRIM, plus the full HVAC group with AIR CONDITIONER COMPRESSOR (SANDEN) and HEATER LINES. The ELECTRICAL section covers FEEDER ELECTRICAL, ENGINE & BATTERY WIRING, and the ALTERNATOR – 150 AMP. Each electrical harness is identified with a part number and grid location. That means when a wire rubs through, you can order the exact harness instead of splicing in a generic pigtail. The CAB COMPONENTS sub-section also lists seat, control levers, and steering column parts – all with factory item numbers.

Using the Alphabetical & Numerical Index (page 3)

Page 3 explains how to use the alphabetical index at the front and the numerical index that follows. The alphabetical index lists major groups and assemblies; the numerical index shows every part number and its grid location and page number. If you know the part number but not the page, the numerical index gets you there. If you only know the system (like “rotor drive”), go to the alphabetical index first. This catalog is designed for a parts counter – fast lookup, minimal flipping. That’s the difference between a factory manual and a collection of scans.

Why OEM Beats Aftermarket Every Time

I’ve seen aftermarket parts catalogs that list “fits many models” and then give a vague description. That wastes your time and money. This is an original factory print – January 2006, part number 79021532G. The pages show illustrations on the left, text on the right. Each part gets an item number, part number, quantity, and description. Even common hardware is indented properly so you know what’s included. You’re not guessing. You’re reading the same document the Challenger assembly line used.

Frequently Asked Questions

Does this manual include torque specs or repair procedures?

No. This is a Parts Catalog, not a service manual. It lists part numbers, quantities, and illustrations for ordering. For torque values and overhaul steps you need the service manual.

Are wiring diagrams included in the electrical section?

The electrical section provides part numbers for wire harnesses, switches, and the alternator, but does not show circuit schematics or connector pinouts. You get the factory harness part number to order the correct replacement.

How do I use the numerical index to find a part?

Go to the numerical index near the front of the catalog. Find your part number – it will show a grid location (e.g., G-4) and a page number. Turn to that page, and the part will be listed in the text with an item number matching the illustration on the left.

Is the cooling system fully covered?

Yes – multiple sections under ENGINE cover the cooling fan drive, radiator slinger, rotary screen, and coolant lines. Each component has its own exploded view and part list, so you can identify and order every piece from a fan blade to a hose clamp.
