Arctic Cat Tigershark Barracuda, Daytona, Monte Carlo, Montego, Montego Deluxe & Tigershark 900 Service Training Manual (P/N 0668-324)

This PDF contains 229 pages of the 1995 Tigershark Service Training Manual issued by Arctco, Inc. It covers all 1995 Tigershark personal watercraft and separates the 639 cc two-cylinder PJ640-AC applications from the 896 cc three-cylinder PJ900-AC where the service data, fuel system, jet pump, and electrical hardware differ.

• Covers 1995 Tigershark Barracuda, Daytona, Monte Carlo, Montego, Montego Deluxe, and Tigershark 900
• Documents PJ640-AC / PJ900-AC engine specifications, complete engine disassembly and inspection, fuel and oil-injection testing, jet-pump service, steering/trim work, electrical diagnosis, and troubleshooting
• Distinguishes Monte Carlo early- and late-run electrical configurations and includes a separate dual-carburetor synchronization supplement for the 1995 Daytona
• Uses model-specific wiring diagrams, assembly schematics, specification charts, torque patterns, and factory special-tool references rather than generic service data

Chapter Breakdown and Content

The main portion runs through General Information, Engine, Fuel System, Jet Pump, Electrical System, Steering and Hull, and Troubleshooting. It covers break-in, storage preparation, submerged-watercraft recovery, engine removal and overhaul, Mikuni carburetor/fuel-pump service, oil-injection testing and synchronization, jet-pump bearing and driveshaft work, steering cable alignment, reverse and trim adjustment, starter-motor repair, charging-system checks, and fault-finding by symptom.

The Tigershark 900 is not treated as a simple displacement variation. After the general troubleshooting material, the manual adds dedicated 900 Engine, 900 Fuel System, 900 Jet Pump, and 900 Electrical System sections for its three-cylinder engine, triple-carburetor layout, counterbalance shaft, separate drive-coupler tooling, load relay/circuit-breaker system, gauges, and 900-specific electrical resistance values. The Daytona also receives a separate dual-carburetor throttle, idle, and choke synchronization supplement.

Named technical views include the Engine Shim Sizes & Part Numbers chart, Impeller Drive Assembly Schematic, Steering Assembly Schematics, Wiring Diagram - 1995 Tigershark 900, Wiring Diagram - 1995 Monte Carlo (early run), and Wiring Diagram - 1995 Montego Deluxe & Monte Carlo (late run). These make the production differences visible before a repair procedure or test value is selected.

Technical Data and Specifications

The engine sections provide wear limits and measurement data instead of relying only on nominal dimensions. PJ640 piston-skirt-to-cylinder clearance is 0.105-0.200 mm, while the PJ900 range is 0.095-0.150 mm. Maximum crankshaft runout is 0.05 mm (0.002 in.). The engine pressure-check procedure is limited to 8 psi, with allowable pressure loss no greater than 1 psi per minute. The PJ640 crankcase fastener table covers 6, 8, and 10 mm hardware, with model-specific torque patterns also supplied for cylinder, head, intake, exhaust, engine-mount, and jet-pump assemblies.

Fuel-system coverage goes well beyond mixture-screw settings. The manual gives carburetor specifications by model and production run, fuel-system pressure testing at 5 psi for 10 minutes, oil-tank pressure testing, fuel-pump vacuum checks, pop-off testing, oil-injection check-valve tests, and oil-pump output charts. It also documents throttle free play, in-water/out-of-water idle settings, oil-injection synchronization, and bleeding. The PJ900 has its own oil-consumption test values rather than reusing the PJ640 data.

Jet-pump service includes a 1.0 mm (0.040 in.) maximum impeller-to-wear-ring clearance, driveshaft wear and deflection limits, bearing and seal inspection, pump-housing removal, and pressure/vacuum leak checks. Drive-unit refill quantity is 177 ml (6 fl oz) of Tigershark Drive Unit Lube. Electrical diagnosis includes separate PJ640 and PJ900 resistance specifications for ignition coils, trigger and lighting coils, spark-plug caps, solenoid circuits, switches, and the 900 load relay. Charging-system data includes a 15.5 V regulator ceiling at 6000 rpm and 3.5-4.0 A charging output at 3000 rpm; the heat sensor is specified to switch at 100 +/- 3 C (206 +/- 5 F).

Factory Repair Procedures and Service Tools

Procedures commonly handled by a repair shop include full engine removal and overhaul, crankshaft and outer-bearing work, engine shimming and drive-coupler alignment, crankcase pressure testing, carburetor/fuel-pump rebuilding, oil-injection pump output testing and synchronization, jet-pump bearing/driveshaft overhaul, jet-pump housing removal, steering and trim adjustment, starter-motor rebuilding, charging-system diagnosis, gauge testing, and model-specific wiring fault tracing. Factory tools called out by part number include the Pressure Testing Kit (P/N 0644-199), Piston-Pin Puller (P/N 0144-003), Bearing Removal and Installation Tool (P/N 0644-216), Jet Pump Removal Tool (P/N 0644-218), Fluke Multimeter (P/N 0644-191), Drive Coupler Gauge P/N 0644-204 for the PJ640 installation, and P/N 0644-237 for the 900.

Several cautions are specific to these assemblies. On the 900 engine, incorrect cylinder-base gasket orientation can block the intended water passage and cause engine damage; oil-pump shaft misalignment can also damage the pump. In the jet pump, bearing/seal orientation and the specified removal tools matter because incorrect handling can damage seals, bearings, or the hull. Engine leak testing must not exceed the manual's 8 psi limit because excess pressure can damage the seals.

The manual repeatedly calls for battery isolation, eye protection, ventilation during fuel-system work, and keeping hands and clothing clear during running flush-kit tests. One scope limit is also explicit: replacement part numbers, quantities, and parts identification are referred to a separate Illustrated Parts Manual, so this publication is intended for service, diagnosis, adjustment, and repair work rather than as a parts catalog. This description summarizes coverage only and does not reproduce executable repair sequences from the manual.
