LOCKING DIFF. GOVERNOR TOOL REVISION (INFORMATIONAL)

SUBJECT: GOVERNOR REMOVING TOOL REVISION

MODEL/YEARS: 1991-92 BRAVADA W/LOCKING DIFFERENTIAL (RPO GSO)

Some technicians may comment that they encounter difficulty when using the locking differential governor removal tool, J 26252. The spacer may interfere with a shoulder on the machined surface of the differential case causing the tool to pull at an angle to the bushing. See the illustrations below.

To correct this condition, the tool has been redesigned with a 45 degree flat added to the spacer. If your spacer does not have this 45 degree flat, it may be modified by adding a flat as shown in the illustrations below. This flat will allow the spacer to center over the governor bushing and pull it straight out. If it is desired, a new spacer with the 45 degree flat may be purchased by contacting Kent-Moore Tools at 1-800-345-2233 and requesting Spacer, J 26252-4.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
