The download contains one English-language printable PDF with 364 pages, including eight front-matter pages and 41 numbered pages without service content. The front matter includes the cover, publication and usage notes, contents, and two BMW service forms marked Order No. 01 71 9 799 131.

Engine, Driveline, Brake, and Electrical Service

These selected workshop topics show the range of repairs and checks covered. The manual also includes oxygen-sensor replacement and headlight aiming.

• Engine repair: Engine removal, cylinder-head and crankshaft service, timing-chain work, bucket-tappet valve adjustment, and combined oil and water pump overhaul.
• Fuel preparation and control: Throttle-body synchronization, CO adjustment, Motronic throttle-position-sensor checks, injector removal, and fuel-pump pressure testing.
• Clutch and transmission: Single dry-plate clutch repair, gear-selector drum and shaft disassembly, gearbox measurements, and shim selection.
• Final drive and chassis: Drive bevel gear repair, Paralever swingarm service, telescopic fork overhaul, steering bearing adjustment, and wheel alignment checks.
• Brakes and ABS: Caliper and master cylinder repair, ABS I and ABS II removal and installation, ABS II pressure modulator bleeding, and sensor gap adjustment.
• Cooling system: Coolant replacement, thermostat testing, radiator and fan removal, pressure testing, and overheating diagnosis.
• Electrical diagnosis: Ignition timing adjustment, Hall generator service, alternator and starter repair, diagnostic flowcharts, relay tests, and wiring-harness location views.

BMW wrote the manual for workshop personnel as a reference alongside the theory and practical skills covered in BMW training.

Inspection Schedules and Engine Overhaul

Inspection schedules run from the initial service through annual maintenance and specify fluid changes for the engine, gearbox, rear drive, and telescopic forks. Engine overhaul coverage includes piston and cylinder measurements, crankshaft bearing checks, valve seat work, and output shaft service. BMW identifies the piston and connecting rod changes introduced on the LT in 1993.

During valve adjustment, leaving BMW camshaft setting fixture 11 3 700 engaged during final sprocket tightening can damage the camshafts.

Motronic Adjustment and Cooling Diagnosis

The throttle-position-sensor checks distinguish Motronic MA 2.1 and MA 2.2. The synchronization procedure explains the BMW Synchrotester's bar and curve displays, and CO adjustment applies to versions without a catalytic converter. For detailed fault-memory readout on MA 2.1 with oxygen-sensor control, BMW refers to the separate diagnosis booklet, Order No. 01 70 9 798 970.

The cooling section covers filler-cap and leak testing alongside component replacement. Its flowcharts help trace a coolant warning light, an inoperative fan, or excessive coolant loss.

Gearbox Shimming and Final-Drive Setup

Shaft and cover measurements guide shim selection for input shaft preload and intermediate and output shaft endplay. A gearbox that drops out of alignment during removal can bend the clutch control rod.

The final-drive section covers crown wheel removal, backlash adjustment, bevel gear contact-pattern checks, and housing cover shimming. Torque tables include the clutch housing, cylinder-head bolt variants, and rear-drive threaded ring.

ABS Service, Forks, and Frame Checks

ABS pressure modulator coverage is limited to replacement and bleeding, with separate procedures for ABS II relay and relay base service. BMW assigns ABS-unit work to authorized BMW workshops. Sensor gap specifications distinguish applications through 1996 from those beginning in 1997.

Chassis procedures include fork alignment and runout checks, frame gauge measurements, wheel balancing, and LT and RS fairing removal. The LT's adjustable windshield has separate actuator and linkage procedures.

Electrical Fault Tracing and Harness Locations

Separate alternator versions have their own service instructions. The alternator, starter, and battery flowcharts help narrow a fault to a component or connection before replacement. The starter-relay test drawings, central relay layout, ABS connector view, and frame harness routing views support local testing and component identification. A complete vehicle wiring schematic requires a separate reference. Instrument cluster procedures cover the circuit boards, clock, tachometer, and speedometer.

Secure the motorcycle and wear appropriate protective equipment when working on fuel, electrical, or heavy mechanical assemblies.

A Sample of Valve, Coolant, and Ignition Specifications

The intake valve clearance specification for both models is 0.15–0.20 mm with the engine cold, at a maximum of 35°C. It accompanies the bucket-tappet adjustment coverage.

For coolant replacement on either model, BMW lists a capacity of 3.0 L plus 0.4 L in the expansion tank.

The ignition data for both models list approximately 13 kΩ secondary resistance for the Bosch double ignition coil.
