Arctic Cat 938K 2013 Parts Catalog – OEM Factory Part Numbers & Diagrams

If you’ve ever ordered a Camshaft for a 938K and got a part that didn’t fit because you trusted an aftermarket listing, you know the waste of time and money. This 618-page OEM Parts Catalog from Arctic Cat gives you the exact factory part numbers, exploded groupings, and assembly order the dealership uses. No reliance on third-party reprints that drop digits or shift hole locations. Every part group is documented the way the build sheet shows it.

Basic Engine Group – Where the Real Work Happens

Under BASIC ENGINE you get 18 separate groups that cover everything from the AIR COMPRESSOR GP to the PISTON & ROD GP. The CAMSHAFT GP (page 8) includes the camshaft, bearings, and thrust plate with the OEM part numbers you need to order the correct replacement. The CRANKSHAFT GP (page 11) shows the crankshaft, timing gear, and keyway dimensions – critical if you’re rebuilding after a bearing failure. The CYLINDER HEAD AS (page 14) lists the valve guides, seats, springs, and retainers for the C7.1 engine. Valve adjustment specs aren’t in this catalog – that’s a service manual function – but the part numbers for the valve train are here, so you can order what you need before you pull the head.

Engine Arrangement and Installation – Getting It Back Together Right

ENGINE ARRANGEMENT splits into ENGINE AR-PRIMARY and INSTALLATION AR-ENGINE. The primary engine arrangement shows the complete assembly with mounting brackets, alternator mounts, and flexible engine mounts. The installation section lists all hardware, including bolt grades and thread sizes. If you’re swapping engines or replacing a mount, you can look up the exact bolt from the MOUNTING GP-ENGINE group. Aftermarket catalogs often combine these into a vague “engine mount kit” that might be missing the isolation pad. This catalog separates every piece.

7 Systems Covered – from Lubrication to Electrical

The catalog breaks the 938K into 7 major system chapters beyond the basic engine: LUBRICATION SYSTEM, COOLING SYSTEM, AIR INLET AND EXHAUST SYSTEM, FUEL SYSTEM, and ELECTRICAL AND STARTING SYSTEM. Each chapter has multiple groups. For example, the FUEL SYSTEM includes 20 groups covering filters, injection pump, fuel lines, and the water separator. The LINES GP-FUEL INJECTION group lists the high-pressure lines with part numbers specific to the C7.1 engine. The ELECTRICAL AND STARTING SYSTEM chapter includes the SENSOR GP-ENGINE and SENSOR GP-POSITION groups – crucial if you’re diagnosing a no-start condition and need to order a crank position sensor.

Source Authenticity – Why OEM Beats Aftermarket Parts Catalogs

This is an original Arctic Cat factory publication (SEBP6895, June 2013). It’s not a scan of a scan or a re-numbered third-party compilation. OEM catalogs use the same part numbering system as the parts counter at your dealer. When you call with a part number from page 8 of this catalog, the counter knows exactly what you’re talking about. Aftermarket parts catalogs often re-index numbers, and I’ve seen them list a camshaft for a different displacement because the editor didn’t check the suffix. With this OEM document, you get the factory grouping and the part number that matches the machine’s build list. For a 938K with serial number HFW1-Up, this is the reference.

If you work on multiple models, check out the Arctic Cat Caterpillar 2013 Parts Catalog – 676 Pages of OEM Part Numbers for the same vintage. For older machines, the CAT Classic Parts Product Book September 2011 covers discontinued part numbers. And for track loaders, the CAT D6N XL LGP 2011 Parts Catalog is a solid companion.

Knowing the proper fluid specifications for your engine is part of the parts-order process. Refer to Motor Oil Specifications to match the correct oil viscosity to the C7.1. If you’re replacing exhaust components, check Catalytic Converters for emissions compliance.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs for head bolts, main bearings, and other fasteners are in the corresponding service manual for the 938K.

How do I use the part numbers in this catalog to order from the dealer?

Each group has an exploded diagram with item numbers referring to a parts list that includes the part number, description, and quantity. Find the group you need (e.g., CAMSHAFT GP on page 8), look at the diagram to identify the item, then read the part number from the table. Call your Arctic Cat dealer and give them that part number. They will confirm availability and price. Because the catalog is OEM, the numbers match exactly what the dealer’s system expects. If you try to order using a description alone, you risk getting a superseded or incorrect part. This catalog eliminates that guesswork.

You’ve got 618 pages of factory part data. Every bolt, gasket, sensor, and bearing is listed with the part number that the factory built the machine with. Access the Factory Manual and keep it on the shop computer so you can look up parts without flipping through a greasy paper copy. When the machine is down and the parts counter needs a number, you’ll have it in seconds.
