BMW R 1100 RT, R 1100 RS, R 850 GS, R 1100 GS, R 850 R Repair Manual

Every time I torque a cylinder head on a BMW boxer, I see the result of someone using a third-party manual that missed the spec by 5 Nm. Stripped threads, head gasket leaks, comebacks that burn hours. This 464-page factory BMW R 1100 RT, R 1100 RS, R 850 GS, R 1100 GS, R 850 R Repair Manual puts the actual OEM numbers in front of you. No interpretation. No translation errors. Just the same book BMW hands their dealership techs. Aftermarket manuals skip the model-specific tightening torques for the R 1100 RT and R 1100 RS – this one has them in black and white.

Torque Specifications for the Boxer Engine

Section 00 of the manual contains two separate torque tables: one for the R 1100 RS / R 1100 RT and another for the R 850 GS / R 1100 GS / R 850 R. The rear wheel studs, cylinder head bolts, clutch housing fasteners – every threaded fastener in the engine assembly has a listed value. You do not guess. You look it up. That procedure saves you a comebacker later.

Valve Clearance Adjustment: Follow the Factory Sequence

The valve clearance check and adjustment procedure in Chapter 00 walks you through the exact order BMW designed – lock the engine at TDC, use the correct feeler gauge thickness, shim selection. The manual even covers taking up slack at the cylinder heads before you measure. If you skip that step, your clearances will be off and the engine will tick like a sewing machine until the valve burns.

Does This Manual Cover the Full Engine Rebuild?

Chapter 11, titled “Motor,” runs from technical data through a sectioned drawing of the engine, lubricating oil circuit, coolant circuit, and cooling oil circuit. Then it dives into removal, dismantling, and assembly. You get the steps for locking the engine at TDC, removing the chain tensioner, valve gear holder, cylinder head, cylinder barrel, pistons, conrods, even measuring main and big end bearing play. Every stage is laid out in the order you work – removal, disassembly, repair, assembly, installation. There is no guesswork.

Engine Electrics: Alternator and Ignition Coil Testing

Chapter 12 covers the electrical side – removing and installing the coil and ignition lead, checking ignition coil resistance, and the alternator removal/dismantling procedure. It includes testing the alternator and checking the armature for short to ground. When the charging system goes down, you need this chapter to confirm the rotor or stator is the problem, not a loose connector.

Over 50 Maintenance Procedures Detailed

The maintenance schedule in Chapter 00 lists pre-delivery check, service data, and intervals I through IV. Specific jobs include: change engine oil and renew oil filter, change gearbox and rear wheel drive oil, check battery acid level, renew air cleaner, renew fuel filter, check and renew spark plugs, adjust poly-V belt and renew it at 24,000 miles, check brake pads and discs, bleed brake fluid using the handbrake circuit, grease side stand and clutch lever, check clutch operating clearance, check tightness of rear wheel studs, and check steering damper. That is a solid 50-plus procedures, each with the required tool list and torque spec.

OEM Authenticity: Why the Factory Print Matters

This manual was published by BMW Motorcycle After Sales in Germany, 02/00. It is not a reprint or a scan of a scan. Every page matches the original dealer document. Aftermarket manuals omit the specific tightening torques for the R 1100 RT and R 1100 RS front suspension or the correct brake bleeding sequence for the ABS system. This one includes everything. The sectioned drawing of the engine alone is worth the price – it shows oil passages and cooling circuit routing you will not find in aftermarket diagrams.

Does this manual cover the R 850 R?

Yes, it covers the R 850 R, R 1100 R, R 1100 RT, R 1100 RS, R 850 GS, and R 1100 GS.

Can I rebuild the engine using this manual?

Yes, Chapter 11 covers the motor in full detail: technical data, sectioned drawing, lubricating oil circuit, coolant circuit, removal, dismantling, valve gear, cylinder head, pistons, conrods, crankshaft, timing chain, and assembly. Every step is described in the order you work: removal, disassembly, repair, assembly, installation. It even includes checking conrods and measuring bearing play. You will not find this level of depth in any aftermarket manual. The factory procedures assume you have the right tools and follow the exact sequence to avoid damage.
