The affected vehicles have been marked with campaign number 0033130000 in AIR.

In order to determine if a specific vehicle is affected by this campaign it will be necessary to verify the vehicle
VIN in AIR (Aftersales Information Research). Based on the response of the system, either proceed with the
repair or take no further action. Please note, open campaigns or vehicle stops may not appear in DCS
Warranty Vehicle Inquiry or sales systems until 24-72 hours after they are announced, therefore AIR is always
the recommended method for determining open campaigns and vehicle stops.

SITUATION
Multiple factors may cause the driveshaft to become damaged; among them are corrosion in certain parts of
the driveshaft, and wear and tear exacerbated by certain climatic conditions.
The following driveshaft failures can occur:

1. The driveshaft can rust onto its mating parts, hindering repair and maintenance work.
2. The splines of the driveshaft at the transmission output shaft or at the differential can corrode. Over time, this
may lead to increased play in the splines which may eventually cause the driveshaft to fail.

3. The bearings of the universal joints may be damaged. This can cause the universal joints to start seizing, which
over time may lead to further damage of the joint.

Letters will be mailed to owners via First Class mail advising them of this Service Action and asking them to
schedule an appointment with an authorized BMW Motorrad dealer to perform the swingarm drain valve
retrofit as well as a driveshaft test, if needed.

PROCEDURE
For the affected vehicles, this service action must be performed at the next workshop visit.

33 02 22_UPDATE: SWINGARM DRAIN RETROFIT AND DRIVE SHAFT CHECK

STEP 1: For all affected vehicles:
Follow repair instruction "00 60 406 – Retrofitting drainage in rear wheel swinging arm” to install a one-way
drain valve in the rear wheel swing arm and punch a ventilation hole in the front rubber boot.

When drilling the hole in the swing arm, note whether any water drains out – this will be important when
performing next steps, below.

STEP 2: Determine Mileage
Once the drain valve is installed, the following work must then be carried out, mileage dependent:
A. Vehicles with less than 1,200 miles:
No additional work is required.
NOTE: A check of a new drive shaft using this test method returns invalid results because the U-Joints are
not run in yet. Do not use the test plan for new drive shafts.

B. Vehicles with mileage greater than 1,200 miles but less than 37,000 miles:
Test the driveshaft for damage according to repair instruction “33 73 002 – Checking Cardan shaft”.

C. Vehicles with greater than 37,000 miles:
Replace driveshaft according to the repair instruction “33 73 000 – Replacing Cardan shaft”. It is essential to
ensure sufficient and thorough greasing of all gearing. Up to 1 gram per spline connection (Klüber
lubricant LFT 71-402). Also observe the current specification for the Paralever bolting to the angle drive
and secure the bolt with Loctite.

NOTICE: If the drive shaft is new, the “Check” is not Necessary.

TESTING THE DRIVESHAFT: Only if directed in STEP 2 above.
This test method is used to check the functional health of the driveshaft while installed in the vehicle and
measures the vibrations of the rear-wheel flange to detect damage in universal joints or gearing.
In the guided measurement procedure, the technician will drive the special speed sensor wheel with a cordless
drill (see the list of approved models, below) across several speed ranges defined in the ISTA procedure.
The service function required for this test is available in ISTA versions 4.36.14 and newer.

Measuring setup

Test procedure

NOTICE: Before the first check the dealer performs, please make sure the software in the special tools
“Measuring control unit” is up to date using ISTA version 4.36.14 and newer. This can be claimed only once
per a dealer.
NOTE: The aluminum pannier rack does not need to be removed to perform this check.

POST-TEST STEPS:
A. If the test results in “Cardan shaft faulty”, Replace the driveshaft according to repair instruction “33 73 507 –
Replacing Cardan shaft with testing”. It is essential to ensure sufficient and thorough greasing of all gearing with
Klüber lubricant LFT 71-402 – PN 83 23 8 847 417. Up to 1 gram per spline connection.
The changed specification for the Paralever bolting to the angle drive must also be observed and the bolting must
be secured correctly with Loctite.
B. If the test results in “Cardan shaft OK” and there was no water leakage after drilling the bore hole for the drain
valve (or only a few drops), no additional work is required.
C. If the test results in “Cardan shaft OK” but there was water leakage when drilling the rear wheel swinging arm for
the one-way drain valve (water that has accumulated in the rear wheel swing arm leaked out from the bore hole),
then the splines at the front and rear must be checked, even with the test result “Cardan shaft OK”.
Replace the driveshaft if:
Driveshaft is stuck to the transmission from corrosion and cannot be removed.
Submit a TSARA case if this necessitates replacing additional parts.
Driveshaft is stuck to the angle drive and cannot be removed using the new special tool to pull off the Cardan
shaft from the rear drive (26 1 930)
Submit a TSARA case if this necessitates replacing additional parts.
Splines are worn out or have play when cleaned up and test-fitted.

Surface rust on the driveshaft or the universal joints has no functional effects and does not justify a
part exchange.

33 02 22_UPDATE: SWINGARM DRAIN RETROFIT AND DRIVE SHAFT CHECK

If reusing the existing driveshaft, the splines must be cleaned thoroughly with a wire brush followed by a
sufficient and thorough greasing of all splines using Klüber lubricant LFT 71-402 – PN 83 23 8 847 417. Up
to 1 gram per spline connection.
NOTICE: The workshop specification for the lubrication of splines of the driveshaft has been revised. The
relevant repair instructions in AIR have been updated.

For replacement or re-greasing of the existing driveshaft, proceed as follows:
Carefully clean and lubricate gearing on driveshaft (1) with a wire brush, using Klüber lubricant LFT 71-402 –
PN 83 23 8 847 417.
Brush on Approx. 1 gram of lubricant with brush in recesses of gearing all the way around.
Apply lubricating material over full length of gearing.

NOTICE: The bolting specification for the Paralever link on the rear axle has been changed. The
relevant repair instructions in AIR have been updated.

Since the existing screw is being re-used, it is essential to clean the screw as well as the thread in the
differential, and use Loctite 2701 - PN 33 17 2 331 095 when re-installing.

The one-way drain valve is inserted correctly in the rear wheel swinging arm and the front gaiter is punctured.
The measure was carried out correctly based on the mileage of the vehicle.
During a visual check or an exchange of the driveshaft, both splines were sufficiently and thoroughly greased (PN
83 23 8 847 417 – Klüber lubricant LFT 71-402).
During a visual check or an exchange of the driveshaft, the Paralever bolting was secured correctly with Loctite
(PN 33 17 2 331 095 – Loctite 2701).

NOTE: Do not replace gaiters with minor damage. If you have questions about what minor damage is
acceptable, please create a TSARA case to review. With the introduction of the rear wheel swing arm
drainage, water tightness of the rear wheel swing arm is no longer required. The gaiters merely serve for
protection from larger amounts of dust as well as mechanical damage of the drive shaft.
