9233chevy01

Number: 91-485-8C

Section: 8C

Date: MARCH 1992

Corporate Bulletin No.: 237202

ASE No.: B1


Subject:
OIL LEAKAGE INTO INSTRUMENT CLUSTER

Model and Year:
1985-88 GEO SPRINT 1989-91 GEO METRO


CONDITION:

Oil may leak into the instrument cluster on some 1985-91 M cars. In severe instances, the oil could drip onto the carpet or the driver's clothing.

CAUSE:

The oil used to lubricate the speedometer cable cannot drain back into the transmission because of the design of the driven gear sleeve. The new style has an oil drain hole added.

CORRECTION:





Replace the parts shown in the illustration, following the instructions in Section 7B of the Service Manual. Although the sleeve (# 1) is the only revised part, all the parts should be replaced to prevent any remaining oil from getting into the cluster again. In rare instances, the instrument cluster and/or carpet may also have to be replaced.

INSTALLATION PRECAUTIONS:

- Be certain the oil seal is fully seated and square to the bore.
- Be certain the slotted end of the driven gear has no sharp edges that might damage the seal when installing.
- Lubricate driven gear and "O" ring seal.
