Engine Mount: Testing and Inspection
ENGINE MOUNTINGS
CAUTION Broken or deteriorated mountings can cause misaligned and eventual destruction of certain drive train components. When a single mounting
breakage occurs, the remaining mountings are subjected to abnormally high stresses.
INSPECTING ENGINE MOUNTINGS
Front Engine Mountings
CAUTION When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal or crankshaft pulley. Due to the
small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause it to be bent against the pump screen, resulting in a
damaged oil pickup unit.
1. Raise the engine to remove weight from the mountings and to place a slight tension on the rubber cushion. Observe both mountings while raising
the engine.
2. Replace the mounting if the following conditions exist:
^ Hard rubber surface covered with heat check cracks.
^ Rubber cushion separated from the metal plate of the mounting.
^ Rubber cushion split through the center.
3. If there is movement between a metal plate of the mounting and its attaching points, lower the engine and tighten the bolts or nuts attaching the
mounting to the engine, frame or bracket.
Rear Mountings
1. Push up and pull down on the transmission tailshaft. Observe the transmission mounting.
2. Replace the mounting if the following conditions exist:
^ Rubber cushion separated from the metal plate of the mounting.
^ Mounting bottomed Out (tailshaft can be moved up but not down).
3. If there is relative movement between a metal plate of the mounting and its attaching point, tighten the bolts or nuts attaching the mounting to the
transmission or crossmember.
