Oil Filter - Modified Wrench
REF. NO. 18/39
TO: OUR MERCEDES-BENZ PASSENGER CAR DEALERS
DATE: OCTOBER 1989
SUBJECT:
MODIFIED OIL FILTER WRENCH
The previously used oil filter wrench for removing and installing spin-on filters could slip when attempting to loosen extremely tight oil filter cartridges.
To aid in removal, the side area of the modified socket is provided with threaded bores for two hex. head screws which may be tightened against the oil
filter cartridge. The socket is thereby clamped against the cartridge preventing any slippage, allowing even the tightest cartridge to be removed.
The top of the socket is provided with 2 additional bores for storing the hex. head screws when not being used.
