Introduction

This repair manual will help you to perform all the main maintenance and repair work correctly and efficiently. If it is consulted regularly by workshop personnel it will form a useful addition to the theoretical and practical knowledge acquired at the BMW Training Centre. It is a contribution towards achieving even higher Service quality.

All information in both text and illustrations refers to motorcycles in standard condition or with genuine BMW accessories installed, and not to motorcycles which have been modified in any way to depart from the manufacturer’s specification.

The repair manual is structured in the logical sequence of the work to be performed: Removal, Disassembly, Repair, Assembly, Installation.

The entire contents are divided into individual chapters, corresponding to the Construction Groups.

Work to be performed during an Inspection is described in Group “00”. The various inspection routines are numbered I, II, III and IV. This numbering is repeated in the work descriptions which follow, so that work can take place without interruption.

Use of the BMW special tools needed for certain tasks is described in the work instructions.

If the need arises, repair instructions are also issued in the form of Service Information. This information is of course incorporated into the next issue of the repair manual. We also recommend, as an additional source of information, the Electronic Parts Catalogue (ETC), which contains clear and easy-to-follow illustrations.

If the work described here is restricted to a particular equipment specification, for instance if a specific optional extra (OE) is fitted, this is stated in square brackets at the start of the item concerned, e.g. [LT].

Please refer to the following pages as well for a description of other symbols used and how to work with it.

Usage

Each chapter starts with the list of contents.

The list of contents is followed by the Technical Data table.

Chapter 00 “Maintenance and general instructions” details the handover checklist and lists all tightening torques and operating fluids.

Key to symbols

In this Workshop Manual for the K 1200 LT model, the following symbols are used; their meanings are explained in the table.

Special instructions aimed at improving the work procedures

L Note:

Specific information on operating, inspecting and adjusting work for the motorcycle as well as maintenance procedures.

e Caution:

Instructions and precautions specifically intended to prevent damage to the motorcycle. Failure to comply with them could invalidate the warranty.

d Caution:

This symbol stands for precautions and measures which are essential in order to protect the rider or other persons from possibly severe or fatal injury.

Remove the break pads

e Caution:

Do not tilt the brake caliper when removing or installing, or the brake pads could be damaged.

Take off the brake fluid reservoir cover complete with the diaphragme.

Add brake fluid.

e Caution:

While renewing the brake fluid, its level must not drop below the MIN mark, or else air will be drawn into the brake circuit.

If this happens, the brake system will have to be bled.

Connect a suitable vessel to the bled screws on the brake caliper to trap the escaping brake fluid, and open the bleed screw by half a turn.

Press the pistons back in the second brake caliper, but do not remove the piston resetting tool.

Close the bleed screw.

Apply the hadbrake lever several times until braking pressure is felt to build up.

Hold the handbrake lever in to maintain the braking pressure and open the bleed screw, at the same time pulling the hanbrake lever up firmly.

eCaution:

Do not release the handbrake lever until the bleed screw has been closed.

Close the bleed screw, then release the handbrake lever.

Allow brake fluid to escape from both brake calipers in succession until it is clear and free from air bubbles.

Close the bleed screw.

Install the brake pads/brake calipers.

L Note:

When adding brake fluid, note the thickness of the brake pads. If the pads are new, add fluid up to the MAX mark.

Brake fluid level = Max mark.

Place the diaphragm and reservoir cover back in position.

Tighten the retaining screws without using undue force.

Make a functional check on the brakes and bleed the brake system if necessary.

Renewing rear brake fluid

The rear brake caliper does not have to be re- mov-ed, nor its pistons forced back.

Continue the procedure as described for front brake fluid renewal.

eCaution:

Do not release the brake pedal until the bleed screws have been closed.
