Arctic Cat Lynx, Puma, Cheetah, Panther, Kitty Cat 1971–1973 Shop, Repair Manual (P/N 0144-063)

• A 200-page PDF of Arctic Cat factory service material covering KT150 single-cylinder, T1A twin-cylinder, and Sachs/Wankel KM914B engines, with removal, teardown, inspection, reassembly, and recoil-starter repair procedures.
• Separate Walbro and Tillotson carburetor sections cover fuel-pump and metering-system service, inlet-control adjustments, and troubleshooting for flooding, poor acceleration, and mixture problems.
• Clutch repair covers St. Lawrence, Salsbury 910/780/770, and Arctic Drive units, plus Arctic Driven pulley service and the eccentric-shaft arrangement used for drive-chain adjustment.
• Suspension procedures extend to skid-frame overhaul, hi-fax slides, torsion springs, idlers, drive-shaft bearings, sprockets, track-belt replacement, and track tension and alignment.
• Electrical coverage provides 1972 engine-specific wiring diagrams, separate recoil- and electric-start circuits where applicable, breaker-point ignition timing, spark-plug and bulb charts, and battery testing and service.
• Scope limits: Kitty Cat coverage is a specification sheet, not a dedicated engine-overhaul chapter. The Steering/Ski and Body chapters listed in the contents are not included in this PDF.

Model Coverage and Engine Repair

The model specifications identify the KT150B-powered Lynx; Puma, Cheetah, and Panther configurations using T1A340S1, T1A400S1, and T1A440S1 twins; and the rotary Panther listed with the KM914 engine. The Kitty Cat sheet identifies the T5A060S1A. Year-specific wiring diagrams and tune-up references are for 1972.

Whether you are preparing for a complete engine teardown or routine maintenance, keep the ignition disabled and fuel lines safely managed.

Along with two-stroke operating theory, the single-cylinder chapter covers KT150A and KT150B engines, including a piston-orientation distinction for 1971-and-earlier KT150 models. Twin-cylinder work extends to axial-fan bearings, fan-belt and sheave service, and cylinder-to-intake-manifold alignment. Crankshaft repair is limited to the main-bearing and seal work described; these sections do not provide a pressed-crankshaft rebuild procedure.

The KT150 Engine/Torque Specifications and T1A Engine/Torque Specifications exploded drawings support the assembly instructions. Related data cover piston-to-cylinder clearance, ring end gaps, inspection limits, and component torque specifications. A specific flywheel-removal caution addresses magneto-coil damage from puller bolts that extend through the flywheel.

KM914B Rotary Service

The rotary section explains Wankel operation and goes into rotor decarbonizing, apex seals, sealing pins and strips, sideplate inspection and refinishing, and mainshaft axial-play measurement and shimming. It also covers test-running, break-in, and engine preservation.

Earlier-component notes distinguish recoil starters without an intermediate flange, starter bells without an emergency-starting device, and adjustable ignition cams. Separate magneto/generator wiring diagrams cover 40-watt and 75-watt systems, with related ignition and air-gap specifications. The manual warns that damage to machined sideplate surfaces can cause engine seizure or loss of sealing.

Carburetor Diagnosis and Ignition Timing

Walbro WD and WR coverage explains the fuel-and-vapor return system; Tillotson operating illustrations distinguish HL, HR, and HD layouts. The rotary engine data identify the Tillotson HL268A. Labeled views such as Walbro’s Part Throttle Operation and Tillotson’s Starting Operation (Choke) show the circuits behind the adjustment and diagnosis procedures.

Repair details include diaphragm and check-valve inspection, metering-lever setting, and Tillotson Welch-plug and nozzle-check-valve work. Fault charts connect operating symptoms with likely fuel-delivery or metering problems.

The Kawasaki ignition chapters provide both Timing Mark Method and Dial Indicator Method procedures, using a continuity indicator. Twin-cylinder instructions distinguish stator adjustment from the separate breaker-point correction for the second cylinder.

Clutch, Track, and Shop References

The drive chapters address roller arms, bushings, spline liners, spring components, and driven-pulley shoe ramps as applicable to each clutch design. The Drive Belt Trouble Shooting chart relates wear patterns to pulley condition, alignment, engagement, and track or drivetrain resistance.

Track repair covers the three-belt construction with riveted metal cleats, including individual center or outer belt replacement and cleat/guide installation. Suspension adjustment is addressed separately from track adjustment.

The special-tool section identifies equipment used in these jobs, including Flywheel Puller Kit 0144-064, Piston Pin Extractor 0144-003, Recoil Spring Retainer 0144-005, and Spring Seating Tool 0144-014.
