Triumph Tiger 955cc 2001 Factory Service Manual (P/N 3857017)

Triumph factory service manual for the Tiger 955cc, P/N 3857017, Issue 1, February 2001. Cylinder-head section incomplete: Removal stops at printed page 3.19; the subsequent head inspection/refitting, valve removal and valve-guide procedures listed in its contents are absent.

Printable PDF and Diagram Readability

Text search and diagram detail: PDF text search and embedded bookmarks are not available. The engine-management and starting/charging diagrams are readable when enlarged. Some text pages are faint, and small wire codes in the two-page full-machine wiring diagram remain difficult to read in places when enlarged.

One printable English-language PDF contains 334 pages, including the cover, front matter and 14 blank pages.

Engine, EFI and Chassis Service

Selected coverage is outlined below. Other included topics range from spark-plug specifications to new-battery commissioning.

• Engine repair: Engine removal/refitting, crankcase separation, crankshaft and piston inspection, cylinder-liner work, cam-chain service, valve-clearance adjustment and balancer timing.

• Clutch and transmission: Clutch cable adjustment, clutch-pack inspection, gearbox shaft disassembly, selector forks and drum, gear-change components, starter gears and sprag clutch.

• Lubrication and cooling: Oil-pump and sump service, oil-cooler inspection, coolant replacement, pressure-cap testing, water-pump service and thermostat testing.

• Engine-management diagnostics: Stored DTCs, live and freeze-frame data, actuator function tests, ECM adjustments, tune-download procedures and electrical/non-electrical fault isolation.

• Suspension and final drive: Rear suspension unit removal/refitting, swingarm inspection, drive-chain replacement, fork disassembly and assembly, oil-level setting and headstock adjustment.

• Brakes and wheels: Brake bleeding, caliper overhaul, master-cylinder service, disc inspection and replacement, wheel removal and wheel-bearing replacement.

• Electrical systems and drawings: Battery and lighting service, alternator and starter removal/refitting, instrument-pack removal, exploded views and system-specific wiring diagrams.

The manual is written primarily for trained technicians in a properly equipped workshop; owners performing basic maintenance and repair need mechanical knowledge and the specified hand and special service tools.

Camshaft and Internal Engine Work

Camshaft service: Cam-cover and cam-chain tensioner procedures lead into camshaft removal and bearing-cap inspection. Valve-clearance adjustment includes shim-selection charts.

Bottom-end repair: Step-by-step procedures cover crankcase resealing, crankpin and journal wear checks, bearing-shell selection, piston-ring and groove inspection, cylinder-bore measurement, and cylinder-liner extraction and installation. Tool references include the T3880315 Cylinder Liner Extractor and T3880016 Balancer Gear Holder.

Camshaft warnings explain how incorrect cap positioning or uneven release can crack caps and damage valves, while the balancer section links incorrect timing to damaging engine vibration.

Clutch and Gearbox Assembly Detail

Clutch instructions cover cable routing, preliminary and final adjustment, pack disassembly, friction and steel plate inspection, and reassembly. Gearbox procedures address individual gears, bushings, bearings and thrust washers, with exploded views of the gear selectors/drum and gear-change mechanism.

The transmission instructions distinguish oil holes that must align from gear holes that must remain offset; incorrect positioning can reduce oil pressure and damage the gears.

Specified tools include the T3880305 Clutch Anti-Rotation Tool and T3880017 Sprag Clutch Holder.

Lubrication and Cooling Components

The Engine Oil Circuit explains oil distribution through the engine and transmission. Pump inspection includes rotor-tip, body and end-clearance checks; sump procedures address the oil-transfer tube and seals. The T3880371 Oil Pump Drive Gear Holder is identified.

Cooling coverage adds radiator removal and inspection to the coolant draining/filling, pressure-cap, water-pump and thermostat procedures.

MC 1000 Engine Management and Fuel Delivery

Fault isolation: Sensor and actuator locations, ECM connector pin numbering and pinpoint test charts link stored fault codes to wiring and component checks. These references support diagnosis before replacement parts are selected.

The T3880250 Engine Management Diagnostics routines cover closed-throttle and adaptive-stepper settings, fuel-trim adjustment and interrupted tune-download recovery. New-tune updates use Triumph’s password-controlled process.

Fuel-system service: Tank, pump and regulator procedures accompany pressure checks using the T3880048 Fuel Pressure Gauge. Separate sections address the airbox, intake-air and crankshaft-position sensors, throttle cable, throttle-body balancing, injectors, throttle-position sensor and idle-air-control valve.

Barometric-pressure information, exhaust removal/refitting, U.S. fuel requirements and California-only evaporative-loss controls are also covered.

Suspension, Brakes and Bodywork

Suspension and chain: Rear shock coverage concerns removal/refitting of the unit with its pressurized reservoir and hose assembly intact. Chain instructions distinguish split-link replacement from continuous-chain work requiring swingarm removal. Fork procedures include oil changes and level setting; the oil-level chart applies specifically to Tiger (VIN 71699 on).

Brake and wheel detail: Front and rear master-cylinder disassembly accompanies disc wear and runout checks. Rear-caliper overhaul refers to the front-caliper procedure. Wheel-bearing replacement includes a bearing-tool selection chart.

Bodywork and frame: Removal/refitting procedures cover the seats, infill and side panels, rear panel/rack and cockpit. Frame and footrest information includes inspection and exploded views.

Electrical Service and Reference Drawings

Lighting instructions include headlight aiming and bulb replacement for headlights, position lamps, rear lights and indicators. Alternator work covers rotor/stator removal and refitting; starter-motor inspection includes free rotation and O-ring condition.

Twelve exploded views cover the cylinder-head/camshaft, clutch, crankshaft/connecting-rod/piston/liner and transmission assemblies. Further drawings include the engine oil circuit, cooling-system layout, engine-management circuit, and lighting, starting/charging, auxiliary and full-machine wiring diagrams with component keys and wire-color codes.

Torque tables, fluid and fuel requirements, scheduled maintenance, bearing-selection charts, wear limits and electrical test values accompany the relevant systems.

Fuel-system repair, brake bleeding, fork disassembly, hot cooling-system work, and engine removal involve pressurized fluids, spring-loaded parts, hot components, and a securely supported motorcycle. The manual’s warning and caution blocks should be followed during shop work.

Sample Valve-Clearance and Brake-Disc Specifications

For cold-engine valve-clearance inspection, the manual specifies 0.10–0.15 mm at the inlet valves and 0.15–0.20 mm at the exhaust valves. Measurement instructions and shim-selection charts accompany these ranges.

The front brake-disc inspection section distinguishes the standard thickness of 5.00 mm from the 4.50 mm service limit, alongside separate runout checks.
