Engine - Idle Shake

Number: 83-92

Section: 6A (VI)

Date: OCT., 1983
Subject: "IDLE SHAKE"


Model and Year: 1982-83 CELEBRITY AND CITATION WITH 2.5L L4 ENGINE AND AUTOMATIC TRANSAXLE
TO: ALL CHEVROLET DEALERS

Some 1982-83 Celebrity and Citation vehicles with 2.5L (LR8/LW9) engines and automatic transaxle may experience an idle shake which can be felt in the steering wheel or may be detected visually on the dash. New torque strut (P/N 14077715) and engine mount (P/N 14073097) have been released to help alleviate this condition. The new parts give more compliance to the engine pitch; therefore, reducing shaking loads into the vehicle.

The following steps should be taken in servicing a vehicle for this condition:

1. Make sure the procedures in the previous bulletins (82T98, 82T26, and 83T26) have been performed.

2. Check front and rear transmission to frame mounts in the area of the interlock finger and clear out rubber flash in that area.

3. Install new torque strut and mount listed above and adjust.

Use applicable labor operation.
