2002 Yamaha TDM900(P) Service Manual (P/N 5PS1-AE1)

This 475-page PDF contains Yamaha’s 2002 TDM900(P) factory service manual, document code 5PS1-AE1, first edition November 2001, for the liquid-cooled, four-stroke DOHC parallel twin. It covers the 5PS1 TDM900 for Europe and 5PS2 TDM900P for Oceania, with region-specific electrical information and full wiring diagrams. Yamaha produced the book primarily for its dealers and qualified mechanics and states that users need a basic understanding of motorcycle mechanics and repair techniques. Coverage is specific to these 2002 configurations; the brake material addresses conventional hydraulic systems and does not include ABS diagnosis or repair.

• Engine and transmission repair: Documents engine removal and installation, camshaft and timing-chain service, cylinder-head and valve work, cylinder and piston inspection, clutch repair, crankshaft/balancer/connecting-rod work, dry-sump oil-pump service, and transmission, shift-drum, and shift-fork procedures.
• Fuel injection and emissions: Explains the Mikuni 38EIS dual throttle bodies, ECU self-diagnosis and fail-safe operation, clock-display fault codes, diagnostic monitoring mode, fuel-tank and pump removal, injector and pump tests, pressure-regulator checks, throttle-position-sensor adjustment, throttle-body synchronization, the three-way catalyst, and air-induction-system testing.
• Chassis and brake service: Details wheel and bearing inspection, wheel static balancing, rear sprocket replacement, brake-pad service, master-cylinder and caliper disassembly/reassembly, hydraulic brake bleeding, front-fork overhaul, steering-head work, rear-shock handling, swingarm service, and drive-chain inspection.
• Cooling and lubrication: Provides radiator and cap testing, thermostat checks, water-pump disassembly and mechanical-seal installation, cooling-system inspection, coolant replacement, oil-flow diagrams, and inspection procedures for the oil pump, relief valve, strainer, delivery pipes, and oil tank.
• Electrical fault isolation: Includes dedicated circuit diagrams and troubleshooting for ignition, electric starting and its cut-off circuit, starter motor, charging, lighting, signaling, radiator-fan control, and fuel injection, along with switch-continuity tests and component-specific electrical values.
• Maintenance and adjustment: Covers the factory maintenance schedule, valve-clearance adjustment, compression and ignition-timing checks, idle-exhaust-gas testing and adjustment, throttle and clutch cable settings, steering and suspension adjustments, brake inspection, battery charging, fuse checks, and headlight aiming.

Diagrams, Job Charts, and Factory Data

The manual contains 37 exploded-view diagrams and 35 cable-routing and system-identification illustrations. Each removal or disassembly drawing is paired with a numbered job chart that identifies parts, sequence, quantities, replacement items, lubrication points, and where additional technical data applies. Particularly useful system views include the fuel-injection circuit diagram, starting-circuit cut-off layout, oil-flow diagrams, cooling-system diagrams, air-induction diagrams, and separate full-page 2002 EUR and OCE wiring diagrams.

Reference tables cover engine, chassis, and electrical specifications; component-specific tightening torques; approved lubricants and fluid capacities; wear limits; inspection clearances; shim selection; and electrical test data. The special-tool section supplies Yamaha tool numbers and intended uses. Examples include the fuel-pressure gauge 90890-03153 with adapter 90890-03176, flywheel puller 90890-01362 with crankshaft protector 90890-01382, fork-seal driver set 90890-01367/01374, and valve-spring compressor 90890-04019 with attachment 90890-04108.

Matched Bearings, Camshaft Caps, and Safe Service

The engine chapter calls for each camshaft cap to return to its original position and for the cap bolts to be tightened evenly; incorrect handling can damage the cylinder head, camshafts, and caps or leave the valve timing wrong. It also warns against interchanging crankshaft journal bearings, big-end bearings, or connecting rods because the matched positions establish the required oil clearances and prevent engine damage.

Fuel-pressure testing, hydraulic-brake work, suspension disassembly, and engine removal require suitable support equipment, test tools, and workshop safety practices. The manual’s warnings and model-specific procedures should be followed before any repair is returned to service.
