This service manual covers the complete Triumph 955i engine and chassis in exhaustive detail. The engine section includes the full 12-valve DOHC cylinder head with valve clearance adjustment via shim replacement, camshaft removal and installation with timing marks, cylinder head bolt tightening sequences with torque-turn specifications, and piston and liner service. The transmission chapter walks through the 6-speed constant mesh gearbox, including selector fork inspection and input/output shaft disassembly. The engine management section includes the full diagnostic trouble code table, sensor and actuator locations, wiring color codes, and pinpoint test procedures for the ECM system. For the chassis, you get complete front and rear suspension specifications, brake system service procedures, and wheel and tyre data. The manual also includes all torque settings in the cylinder head, clutch, crankcase, transmission, lubrication, cooling, fuel, exhaust, suspension, wheels, brakes, footrest and bodywork sections.

Engine Management & Diagnostics

The fuel system and engine management chapter is one of the most detailed sections in this Triumph Daytona 955i and Speed Triple 955 service manual. It explains how the electronic engine management system controls both ignition and fuel delivery, with full sensor and actuator descriptions. You get the complete Diagnostic Trouble Code (DTC) table covering crankshaft sensor, camshaft sensor, idle air control valve, injectors, ignition coils, lambda sensor, coolant temperature, fuel pump relay, cooling fan relay, secondary air injection and more. Each code includes the number of no-fault cycles before the MIL turns off and before the DTC is erased. The pinpoint test procedures walk through terminal and cable integrity checks, resistance values, short circuit and open circuit tests, and sensor resistance measurements. There is also a full diagnostic tool operation guide covering current data, freeze-frame data, function tests and adjustments such as closed throttle position, adaptive stepper position and long term fuel trim. Circuit diagrams for the crankshaft sensor, idle air control, fuel injectors and throttle position sensor are included.
