1999–2000 Triumph Tiger 900 (885cc) Factory Service & Repair Manual (P/N 3850775)

This Triumph factory service manual covers the 1999–2000 Tiger 900 with the 885cc transverse inline three-cylinder engine and electronic fuel injection. Part Number 3850775, Issue 3, August 1999, contains 16 chapters covering scheduled maintenance, engine repair, chassis service, and electrical diagnosis.

The download contains a 378-page PDF scan with chapter bookmarks. The pages are image-based, without searchable text or an embedded OCR layer.

• Engine repair: Engine removal and installation, cylinder-head overhaul, camshaft timing, crankcase separation, piston and liner inspection, and balancer shaft alignment.

• Clutch and transmission: Wet-clutch disassembly, clutch-drum shimming, transmission shaft and selector inspection, reassembly, and starter sprag-clutch service.

• Fuel injection and engine management: MC2000 and MC1000 fault diagnosis, fuel-pressure testing, throttle-body synchronization, actuator tests, and adaptation resets.

• Lubrication and cooling: Oil-pump inspection, lubrication circuit diagrams, water-pump service, thermostat and pressure-cap testing, and coolant renewal and bleeding.

• Suspension, brakes and final drive: Fork overhaul, steering-head adjustment, swingarm service, brake hydraulic repair and bleeding, wheel-bearing replacement, and drive-chain service.

• Electrical troubleshooting: VIN-specific wiring diagrams, ECM connector pin views, lighting and starting/charging circuits, electrical test values, and starter and alternator removal.

Written primarily for trained technicians in properly equipped workshops, the manual also supports basic maintenance and repair by owners with mechanical knowledge and the required hand and special service tools.

Engine, Clutch and Transmission Repair

Cylinder head and valve train: Intake and exhaust valve-clearance adjustment charts cover shim selection, with procedures for valve and stem-seal replacement, timing-chain service, and camshaft installation. The timing cautions explain how incorrect camshaft positioning can cause valve-to-valve contact and damage the valves and cylinder head.

Crankshaft and liners: Bearing selection charts, crankpin inspection dimensions, bearing-clearance checks, and component wear limits support internal engine assessment. Cylinder-head and crankcase torque tables accompany the assembly procedures. Cylinder-liner work specifies extractor T3880315.

Valve guides and seats are not individually replaceable, and the manual rules out crankshaft regrinding and oversize bearings.

Clutch and gearbox: Exploded assembly views distinguish the clutch plate arrangement and anti-judder components. The clutch procedures specify anti-rotation tool T3880305. Transmission coverage extends to input/output shafts, selector forks and drum, gear ratios, and the sprag clutch; sprag-clutch access requires engine removal and crankcase separation.

Fuel Injection and ECM Diagnostics

ECM variants: MC2000 coverage applies through VIN 89736, with one large ECM connector and a separate barometric-pressure sensor. MC1000 coverage starts at VIN 89737, with two ECM connectors and an integral barometric sensor.

These distinctions help match the motorcycle to the correct connector pinout and diagnostic chart before electrical testing or parts selection.

Factory diagnostic-tool procedures specify T3880250 and cover trouble codes, live data, freeze-frame information, actuator checks, and throttle-position and adaptive-stepper resets. Separate routines address open-loop fueling and closed-loop fuel adaptation. Tune download and recovery procedures require the specified diagnostic equipment and Triumph authorization.

Fuel delivery and emissions: Fuel-pressure diagnosis uses gauge T3880048. Pump, regulator, injector, and throttle-body procedures sit alongside non-electrical troubleshooting for poor running and idle faults. California evaporative-emission coverage includes the purge valve and carbon canister.

The fuel-pump cautions explain why running the pump with its delivery hose disconnected can damage the filter or dislodge in-tank hoses. Working on high-pressure fuel systems and internal engine components carries inherent risks. Follow the manual’s safety precautions and consult a qualified technician if the work exceeds your experience.

Lubrication and Cooling Service

The Engine Oil Circuit diagram accompanies oil-pump clearance checks, oil-cooler service, and oil-transfer-pipe work. Cooling references include thermostat test criteria and fluid-capacity specifications.

Suspension, Brake and Chassis Repair

The Fork Oil Level Chart identifies Tiger VIN 71699 onward. Fork procedures cover seals, bushings, and oil-level setting; rear-shock coverage is removal and installation of the complete unit, not internal damper overhaul.

Brake sections cover caliper and master-cylinder components, seal inspection, and disc wear and runout limits. Chassis procedures extend to cush-drive bearings, spoked wheels, body-panel removal, and frame inspection.

Electrical Circuits and Component Service

The ECM Connector Pin Numbering views, Lighting Circuit Diagrams, and Starting/Charging Circuit Diagram supplement the complete motorcycle wiring sheets. Electrical component service also covers battery maintenance, headlight adjustment, and instrument-panel removal.

File Format and Readability

Included pages: One added cover plus 377 manual pages make up the 378-page total. The original front matter and 12 blank pages are already included.

Navigation: Eighteen PDF bookmarks lead to the title page, contents, and all 16 chapters; individual repair procedures are located through the chapter contents pages.

Scan quality: Small pin numbers and wire-color codes on the dense wiring sheets need magnification, and the scans retain some grain. An explanatory line above the MC1000 connector diagram on printed page 9.79 is partially clipped.
