2010 Yamaha FX Nytro, RTX, XTX, RTX SE, MTX & MTX SE 153/162 Snowmobile Service Manual Set (P/N LIT-12618-02-69)

This Yamaha FX Nytro service manual set (LIT-12618-FX-01) combines the base manual with the 2009 and 2010 supplements for the FX Nytro, RTX, XTX, RTX SE, MTX, and MTX SE 153/162. The supplements supply revised procedures and specifications for their listed FX10 variants.

• Engine repair: Engine removal, camshaft timing, valve-clearance adjustment, cylinder-head service, crankcase separation, and inspection of pistons, connecting rods, crankshaft, and balancer shaft.

• Cooling system: Radiator and heat-exchanger service, thermostat testing, water-pump overhaul, cooling-system pressure checks, and coolant replacement and bleeding.

• Fuel injection: ECU fault-code tables, diagnostic mode, T.O.R.S. checks, throttle body synchronization, fuel-pressure testing, and sensor troubleshooting.

• Clutches and chaincase: Primary and secondary sheave disassembly, belt inspection, sheave offset adjustment, drive-chain service, and reverse-system components.

• Steering and suspension: Ski and ball-joint inspection, front-suspension removal, slide rail suspension service, front-axle and track work, and variant-specific shock adjustments.

• Brake repair: Caliper and master-cylinder disassembly, seal inspection, hydraulic bleeding, brake-pad replacement, and parking-brake adjustment.

• Electrical diagnosis: Starter-motor inspection, stator-coil testing, charging checks, grip/thumb warmer troubleshooting, and lighting, signal, and radiator-fan circuit tests.

Yamaha wrote these manuals primarily for dealers and qualified mechanics who already understand snowmobile mechanics and repair techniques.

How the Base Manual and Supplements Work Together

The base manual has nine chapters. The 2010 supplement’s foreword requires both earlier publications for complete service information. Its updates include crankcase assembly, drive-chain installation, steering, suspension, and revised fuel-injection and electrical information.

Separate suspension sections distinguish Dual Shock CK, Dual Shock Pro 46, Dual Shock CK 144, and Pro Mountain Air configurations. These distinctions help match the service and adjustment information to the installed suspension rather than applying one setup across the lineup.

Engine, Cooling, and Fuel-System Service

Engine coverage runs from engine-oil and filter replacement to valve-seat and guide inspection, valve-pad selection tables, oil-pump clearances, and connecting-rod and crankshaft bearing selection. Exploded assemblies, timing illustrations, and cylinder-head bolt torque instructions accompany the work; the 2010 crankcase section includes staged torque-and-angle tightening.

Water-pump overhaul covers the impeller, bearings, oil seal, and mechanical seal. The tool references identify mechanical seal installer 90890-04145 and bearing driver 90890-04058. The disassembly cautions address scratches to the impeller shaft, while crankcase removal notes address damage to the sealing faces.

Cooling-system service distinguishes the mountain-model heat-exchanger arrangement and its draining and bleeding requirements.

EFI troubleshooting links displayed fault codes to sensor and circuit symptoms, diagnostic checks, and the ECU’s starting and driving restrictions. The tables distinguish electrical pressure-sensor faults from blocked or disconnected pressure-sensor hoses.

Clutch Tuning, Brakes, and Chassis Work

Clutch and gearing charts relate spring, weight, roller, and torque-cam selections to operating conditions, including elevation. The base manual provides separate chaincase service layouts for machines with and without reverse.

Brake coverage goes beyond pad changes to caliper and master-cylinder inspection and assembly. Steering and suspension sections include ball-joint checks, ski alignment, shock handling notes, and troubleshooting charts for handling and ride complaints.

Rotating clutches, spring-loaded sheaves, and hot pressurized coolant require the precautions given in the relevant service sections.

Electrical Circuit Diagrams and Fault Tracing

Circuit diagrams for ignition, electric starting, charging, and grip warmers accompany system-specific troubleshooting charts. Revised fuel-injection circuit diagrams and the 2010 wiring diagram provide further circuit and connector references.

Cable-routing drawings show harness, hose, and control-cable paths. Electrical specifications include coil and sensor resistances, charging-system checks, and starter-motor inspection limits.

Track and Thermostat Specification Preview

These examples are a small selection of the adjustment and inspection data in the 2010 supplement.

Track deflection: Under a 100 N load, the specified range is 25.0–30.0 mm for FX10Z/FX10RTRZ/FX10XTZ and 30.0–35.0 mm for FX10RTRSZ/FX10M53Z. The FX10M53SZ/FX10M62SZ range is 40.0–45.0 mm under the same load.

Thermostat inspection: The opening-temperature specification is 69.0–73.0 °C. The cooling section also contains the thermostat inspection procedure.

PDF Search, Bookmarks, and Included Publications

Finding text and reading diagrams: Text search is available in much of the supplements, but most base-manual pages and some table content have no searchable text. Embedded bookmarks cover all three publications. Small wire-color codes and connector references in the large wiring diagrams require zooming.

One printable, 726-page PDF contains the following publications and collection cover:

The total already includes the collection cover, individual publication covers, seven empty pages, two ruled separator pages, and wiring-diagram pages.
