2005 Arctic Cat 370, 440, 500, 550, 570, 600, 700, and 900 cc Snowmobile Service Manual (PN 0639-130)

• Official Arctic Cat manual (P/N 0639-130, October 2004 release) featuring 815 pages of exact assembly schematics and diagnostic routines.
• Complete 2005 lineup coverage: 370, 440, 500, 550, 570, 600, 700, and 900 cc engines.
• Subsystem data dedicated to standard, Firecat, Sabercat, King Cat, and M-Series platforms.
• Factory benchmarks for engine teardowns, fuel delivery, electrical troubleshooting, and drivetrain tuning.

Tackling carbureted setups, complex EFI systems, or the 500/600/700 cc Laydown engines requires accurate factory reference material. This manual breaks down the entire vehicle architecture. You get immediate access to component sub-assemblies, fuel routing, chassis wiring diagrams, and rear suspension geometry. Rebuilding high-performance snowmobiles leaves no room for guesswork. Rider safety directly depends on strict adherence to factory tolerances and correct assembly procedures. The publication clearly defines required locking agents—including Loctite 242, 271, and 609—alongside essential guidelines for torque conversions, piston replacement, and measuring crankshaft runout.

Engine Specification Highlights

Hard numbers make or break a rebuild. This document delivers exact cylinder bore and stroke dimensions, compression ratios, and cooling system capacities. Fastener torque values, including critical head bolts and engine mounts, are provided in both metric (Nm) and standard (ft-lbs) measurements. Checking for internal wear? You will find intake flange flatness tolerances, crankshaft runout limits, and precise piston-to-cylinder clearance thresholds to verify your components. Finally, factory idle specifications and timing data let you dial in the engine for peak trail performance.
