Arctic Cat 500, 400 FIS, 650 H1, 650 V-Twin Technical Manual

If you’ve ever had a brake master cylinder leak on a 650 V-Twin and tried to rebuild it with aftermarket parts, you know the frustration of finding out the cylinder is a non-serviceable assembly. That’s right – Arctic Cat designed it to be replaced as a unit, not overhauled. This 16-page Arctic Cat 500, 400 FIS, 650 H1, 650 V-Twin Technical Manual saves you that wasted time. It’s a factory document, not a third-party rewrite, so the specs, diagrams, and steps came straight from the engineers who built the ATV. No guesswork on which bolt goes where.

Hand Brake Lever and Master Cylinder: Non-Serviceable Assembly

Page 9-2 walks you through removing the hand brake lever and master cylinder assembly. The manual is blunt: the master cylinder must be replaced as a unit. No disassembly, no seal kit. You get a full sequence – drain brake fluid via bleeder valve, disconnect the hose, remove the circlip and pivot pin, then unbolt the clamp from the handlebar. The inspection steps are clear: check the lever pivot hole for elongation, look for cracks in the reservoir, inspect the brakelight switch tabs. Brake fluid is corrosive – the manual has a CAUTION about spilling it on any ATV surface. That kind of warning matters when you’re working in a hurry.

Drive Selector and Front Differential Lock for 400 FIS/500/650 H1/650 V-Twin

The drive selector section (page 9-8) covers the specific linkage and cable routing for these models. The front differential lock is separate for FIS models – the manual splits it out because the mechanical engagement is different. If you’ve ever had a 400 FIS that wouldn’t lock the front diff, this is the page that shows the correct lever orientation and cable adjustment. The Transmission sections cover both manual and automatic reverse shift levers (pages 9-9 and 9-10). The manual distinguishes between the manual gearshift pedal (page 9-7) and the automatic shift lever for the 500, 650 H1, and 650 V-Twin. If you need more on manual transmission repair, see Manual Transmission for external context. For emissions components like catalytic converters, refer to Catalytic Converters.

What the 16-Page Technical Manual Covers

This is Section 9 – Controls/Indicators. It’s not a full service manual. It covers exactly: Hand brake lever/master cylinder assembly, auxiliary brake schematics, throttle control, gearshift pedal (manual transmission), drive selector (300 model and 400 FIS/500/650 H1/650 V-Twin), front differential lock (FIS models), reverse shift lever (manual and automatic), and speedometer/indicator lights (analog and electronic versions for each model). Every page has the factory’s note style and torque callouts where applicable. The Brake system diagrams use OEM part numbers. If you’re rebuilding a 650 H1’s brake system, you want this, not a generic illustration.

Speedometer and Indicator Lights: Analog vs Electronic

Three separate pages cover the speedometer/indicator lights: analog (page 9-12), electronic for 400 FIS/500/650 H1 (page 9-13), and electronic for 650 V-Twin (page 9-14). The wiring pinouts and bulb types are listed. If your indicator light stays on after releasing the hand brake, the manual shows the switch location and adjustment procedure. No scanning QR codes to find PDFs – it’s printed plain.

Source Authenticity: Factory OEM, Not Aftermarket

You’re buying a direct scan of the Arctic Cat factory technical manual. The OCR excerpt I saw includes a note: “For Arctic Cat Discount Parts Call 606-678-9623 or 606-561-4983” – that’s a dead giveaway of an original dealer document. Aftermarket manuals often skip the non-serviceable component notes. This one doesn’t. It tells you if a part is replaceable only as an assembly. That alone can save you from ordering a seal kit that doesn’t exist.

Frequently Asked Questions

Does this manual include torque specs for the brake caliper?

No. This is the controls/indicators section – it covers removal, inspection, and installation procedures for levers, cables, and switches. For caliper torque values, you need the brake system section from a full service manual.

Is the master cylinder really non-serviceable?

Yes. Arctic Cat says it must be replaced as an assembly. The manual repeats that in a note on page 9-2.

What models are covered in this technical manual?

The manual specifically lists: 400 FIS, 500, 650 H1, and 650 V-Twin. Some sections (like drive selector for 300 model) are included for reference, but the primary content focuses on these four.

Can I use this for a 650 H1 automatic transmission reverse lever?

Yes. Page 9-10 is dedicated to the reverse shift lever for 500/650 H1/650 V-Twin automatic transmissions. The procedure is specific to that linkage.

You’ve got enough experience to know that a factory manual is the only thing you can trust when bleeding brakes on a 650 V-Twin or adjusting the drive selector on a 400 FIS. Access the Factory Manual and get the Arctic Cat procedures on your screen or printed out – no more scrolling through forum posts.
