Introduction

This repair manual will help you to perform all the main maintenance and repair work correctly and efficient­ly. It should be consulted regularly by workshop personnel as an addition to the practical and theoretical knowledge obtained in Training School courses. 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, Dis-
assembly, Repair, Assembly, Installation.
● The entire contents are divided into individual chapters, corresponding to the Construction Groups.
11 . 10
Chap. Page number within chapter
● 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 you to consult the detailed illustrations on the Parts microfiches as an additional source of information.

Final inspection and function check

Handing over the motorcycle

Clutch
•
Check gear shift action.
•
Handbrake and foot brake
•
Check lights and signalling equipment:
•
– Front and rear parking lights – Instrument lighting – Low and high headlight beams, headlight flasher – Brake light (operate front and rear brakes) – Turn signals left/right – Hazard warning flashers –Horn – Telltale and warning lights – Instruments
Check function of optional extras:
•
– ABS: perform starting test. When a speed of
5 km/h (app. 3 mile/h) is reached, both ABS warning lights must go out.
If necessary, take the motorcycle for a test ride.
•
Confirm pre-delivery check in Service and Tech-
•
nical booklet.
See “Inspecting motorcycle for damage” if de-
•
fects are detected.

Final cleaning

Clean the motorcycle.
•
L Note:
Do not use a steam or high-pressure water jet. The high steam or water pressure could damage seals, the hydraulic system or electrical components.
This is the ideal opportunity to familiarise the cus­tomer with the motorcycle in order to ensure the customer’s satisfaction and safety.
The following points must be demonstrated and
•
explained to the customer:
– documentation and stowage space – toolkit and stowage space – suspension preload adjustment to suit total
weight – checking brake fluid/clutch operating fluid – provision for adjusting handlebar lever positions – how to adjust the mirrors – controls – instruments and telltale lights – optional equipment and accessories fitted. – noise during the regular ABS self-diagnosis pro-
cedure
The user must be given the following information:
•
– running-in recommendations and inspection in-
tervals – safety check – the clutch fluid level rises gradually as the motor-
cycle is ridden (clutch lining wear) – before checking the engine oil level, the engine
must be switched off for at least 10 minutes and
the motorcycle must be standing on a flat, level
surface

Replacing valve guides
Heat cylinder head slowly and uniformly to
•
200 °C (392 °F) in a suitable oven.
e Caution:
Wear protective gloves when handling heated parts.
Drive out valve guides with 5 mm (0.20 in) dia.
•
drift, BMW No. 11 5 674, from the combustion chamber side. Allow cylinder head to cool down to room tem-
•
perature (app. 20 °C/68 °F). Examine valve guide bore for:
•
–wear, – widening taper and – correct dimensions in H7 tolerance range
(12.500...12.518 mm/0.4921...0.4928 in).
L Note:
Valve guides are press-fitted in the cylinder head with an interference fit of 0.015...0.044 mm (0.0006...0.0017 in).
If valve guide bore is undamaged and dimen­sions are within correct 12.5 H7 tolerance range:
Use original 12.5 U6 (12.533...12.544 mm/
•
0.4934...0.4939 in) valve guide. Measure valve guides with micrometer.
•
Slowly heat cylinder head to 200 °C (392 °F) in a
•
suitable oven. Immerse valve guide in liquid grinding paste.
•
Chill valve guide with dry ice.
•
e Caution:
Immediately before pressing in, the temperature
must be –40 °C (–40 °F).
Place heated cylinder head flat on workbench or
•
a similar surface.
Mount the chilled valve guide on Ø 5 mm (0.20 in)
•
drift, BMW No. 11 5 673.
Drive valve guides into cylinder head with no de-
•
lay. Allow cylinder head to cool down to room tem-
•
perature, app. 20 °C (68 °F). Inspect bores of valve guides.
•
L Note:
Valve guides for repair purposes are produced with an internal diameter of 5.01 mm (0.1972 in) H7. In most cases, the bore is within the 5.00 mm (0.1969 in) H7 tolerance range after pressing in. If the bore is too narrow, ream it out to size.
If valve guide bore is undamaged but slightly larger than the 12.5 H7 tolerance range:
Use replacement valve guide
•
12.550...12.561 mm (0.4941...0.4945 in).
If valve guide bore is damaged or not to correct dimensions in 12.5 H7 tolerance range:
Use an oversize 12.7 U6 (12.733...12.744 mm/
•
0.5013...0.5017 in) valve guide.
Repair method 1 – ream out the bore (if bore is damaged or not to correct dimensions)
Determine actual diameter of valve guide using
•
micrometer.
Ream bore with Ø12.7 H7 mm
•
(12.700...12.718 mm/0.5000...0.5007 in) ream­er.
Repair method 2 – turn the valve guide on a lathe (bore must not be damaged)
Measure bore with internal measuring tool.
•
Calculate the nominal diameter of the valve
•
guide:
Required diameter of valve guide = bore dia. + inter­ference-fit value (0.015...0.044 mm/
0.0006...0.0017 in). Use an oversize 12.7 U6 (12.733...12.744 mm/
•
0.5013...0.5017 in) valve guide. Machine oversize valve guide to required diame-
•
ter.
