BMW R 1200 CL Repair manual

Repair Manual

R 1200 C
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.
A new issue of this repair manual will be published if amendments or additions (supplements) are needed.
The latest issue date is shown in the header of the microfiche. Microfiches rendered invalid by the new issue
should be destroyed without delay.
All information in both text and illustrations refers to motorcycles in standard condition or with Original 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, Dismantling, 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.

• Measure valve guides with micrometer.
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 12.7U6 (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.
• Open out bore with Ø12.7 H7 mm
(12.700...12.718 mm/0.5000...0.5007 in) reamer.
Repair method 2 – lathe-turn the valve guide (bore
must not be damaged)
• Determine actual diameter of bore with internal
measuring tool.
• Calculate the nominal diameter of the valve
guide:
Nominal 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.
• Turn down oversize valve guide to nominal dimension.

Place heated cylinder head flat on workbench or
a similar surface.
After cooling, place the valve guide on driving-in
pin, driving-in pin, Ø 5mm (0.20 in),
BMW No. 11 5 673.
Insert valve guides into cylinder head with no delay.
Allow cylinder head to cool down to room temperature, app. 20 °C (68 °F).
Inspect bore in valve guide.
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.
