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.

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

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-
–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)

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/
If a valve was removed, the valve stem seal must be
replaced.
Oil the stem before installing the valve.
•
Shrink a short length of tube (arrow) on to the end
•
of the valve stem.
Install the valve stem seal with a 5 mm (0.20 in)
