Dear Dealer,
It an oil leak on the rear drive โ ust be repaired, use the
following guidelines:
General
Never install a replacement seal without a BMW- special tool,
this seal is a delicate design, if re-shaped, by incorrect
tools, could be damaged before its intended use.
Inspect and remove any obstructions in the path of the seal
before installation of the seal.
ยทCoat the seal, O.D. and I.D., with light grease, slightly !or
easier installation.
1.) Sealing toward the swinging arm
The seal, Part No. 33 12 1 230 356 must be installed with a
special tool, No. 33 1 750. The threaded ring and threads in
the housing must be perfectly cleaned, free o! oil and grease.
Coat the threaded portion of the ring with Hylomar S032, or
other proven sealant before installation.
Do not coat spacer ring, Part No~ 33 12 1 230 353 or shim,
~rtlfo. 33 12 1 230 525 with gasket cement.
Reason: The rubber seal ring, Part No. 33 12 1 233 302, will
seal this assembly, preventing any rear drive fluid to leak
into the drive shaft tunnel.
