Arctic Cat 1971–1973 Snowmobile Service Manual — Lynx, Puma, Cheetah, Panther & Kitty Cat

This Arctic Cat snowmobile service manual for 1971–1973 includes model specifications for the Lynx, Puma, Cheetah, Panther, and Kitty Cat, with separate workshop sections for Kawasaki piston engines and the Sachs/Wankel rotary engine.

PDF Search, Wiring Diagrams, and Page Count

Text search and diagram labels: The PDF has searchable OCR text. Some wiring labels are missed by text search, and small terminal markings and wire-color labels are easier to read when zoomed in. There are no embedded PDF bookmarks.

The ZIP contains one printable English-language PDF with 200 pages, including 15 contents pages, 12 blank pages, six notes pages, and one special-tools divider.

Engine, Clutch, and Track Service

This selection of workshop topics is supplemented by metric-to-inch conversion charts and a rotary-engine lubrication schedule.

• Kawasaki engines: KT150 single-cylinder and T1A twin-cylinder removal, teardown, inspection, reassembly, and recoil-starter repair.

• Wankel rotary: KM914B rotor and seal inspection, sideplate service, mainshaft shimming, and magneto service.

• Carburetors: Walbro and Tillotson fuel-pump and metering-system service, inlet-control adjustments, and troubleshooting for flooding, poor acceleration, and mixture problems.

• Electrical: Engine-specific 1972 wiring diagrams, separate recoil- and electric-start circuits where applicable, breaker-point timing, spark plug and bulb charts, and battery testing.

• Clutches and drive belt: St. Lawrence, Salsbury 910/780/770, and Arctic Drive primary clutch repair, plus Arctic Driven pulley service and drive-chain adjustment.

• Suspension and track: Skid-frame overhaul, hi-fax slide and torsion spring service, idler and driveshaft bearing work, sprockets, track-belt replacement, tension, and alignment.

• Coverage limits: The Kitty Cat has a model specification sheet. Steering/Ski and Body appear only as entries in the table of contents.

The teardown, timing, and inspection procedures suit mechanics and experienced restorers familiar with pullers, dial indicators, and feeler gauges.

KT150 and T1A Engine Repair

The single-cylinder chapter covers the KT150A and KT150B and explains the piston-orientation difference on 1971-and-earlier KT150 engines. Twin-cylinder procedures cover axial-fan bearings, fan belts and sheaves, and cylinder alignment using the intake manifold.

The KT150 and T1A exploded drawings pair component layouts with assembly torque data. The engine sections also cover two-stroke operation, piston and ring inspection, and crankshaft service limited to the bearings and seals described.

Keep the ignition disabled and fuel lines secured during engine service. The flywheel-removal procedure identifies how puller bolts that project through the flywheel can damage the magneto coils.

KM914B Rotary Overhaul

The rotary section explains Wankel operation and covers rotor decarbonizing, apex seals, sealing pins and strips, sideplate refinishing, and mainshaft axial-play checks. It also covers test-running, break-in, and storage preparation. Damage to machined sideplate surfaces can cause seizure or loss of sealing.

The component-change notes distinguish earlier recoil starters without an intermediate flange, starter bells without an emergency-start device, and adjustable ignition cams. Separate diagrams identify the 40-watt and 75-watt magneto/generator circuits.

Fuel Metering and Ignition Diagnosis

Walbro WD and WR coverage explains the fuel-and-vapor return circuit. Tillotson diagrams distinguish HL, HR, and HD layouts, and the KM914B service data identify the Tillotson HL268A. Labeled views show which circuits operate during choke and part-throttle operation.

Carburetor service includes diaphragm and check-valve inspection, metering-lever adjustment, and Tillotson Welch-plug and nozzle-check-valve work. The fault charts link symptoms to likely fuel-delivery and metering problems.

The Kawasaki ignition sections give timing-mark and dial-indicator methods using a continuity indicator. The T1A procedure distinguishes stator adjustment from breaker-point correction for the second cylinder. Battery service includes hydrometer testing and charging guidance.

Clutch, Track, and Shop References

The drive chapters cover roller arms, bushings, spline liners, spring components, and driven-pulley shoe ramps as applicable. The belt troubleshooting chart helps distinguish pulley misalignment from clutch faults or a binding track by comparing wear patterns and likely causes.

Track repair covers the three-belt construction with riveted metal cleats, including replacement of an individual center or outer belt. The suspension section separates skid-frame adjustment from track tension and alignment.

The illustrated tool section identifies the flywheel puller kit 0144-064, piston pin extractor 0144-003, recoil spring retainer 0144-005, and spring seating tool 0144-014.

Selected Engine Clearances and Track Settings

For KT150 assembly, the manual gives a standard piston-to-cylinder clearance of 0.0035 in. at the skirt and a maximum of 0.005 in.

The KM914B data specify 10°–12° BTDC ignition advance. After ignition-coil or lighting-armature replacement, the air gap between the core shoes and magnets is 0.009–0.013 in., measured with the mainshaft bearings in good condition.

For 1972 track adjustment, the distance from the track to the underside of the skid frame is 2 in. on the Lynx and Puma and 1 in. on the Cheetah and Panther, measured with the rear of the snowmobile raised off the ground.
