Crankshaft Rear Seal with Retainer Plate: Removal

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTE: The engine is equipped with a cast aluminum (early build) or stamped steel (late build) crankshaft rear seal retainer plate. If the engine is equipped with a stamped steel retainer plate, the seal and plate must be removed as an assembly and discarded.

With the vehicle in NEUTRAL, position it on a hoist. Refer to JACKING & LIFTING .
Remove the flexplate. Refer to FLEXPLATE .
NOTE: The engine can be equipped with a cast aluminum (early build) or stamped steel (late build) crankshaft rear seal retainer plate.

NOTE: Cast aluminum crankshaft rear seal retainer plate shown in illustration, stamped steel crankshaft rear seal retainer plate similar.

Remove the crankshaft sensor ring.
Remove the engine-to-transmission spacer plate.

NOTE: Place clean, lint free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gaskets surfaces) that enters the oil passages or the oil pan, may cause engine failure.

NOTE: Do not use wire brushes, power abrasive discs or 3M™ Roloc® Bristle Disk (2-in white, part number 07528) to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. They also cause contamination that causes premature engine failure. Remove all traces of the gasket.

Clean the sealing surfaces of the cylinder block and oil pan flange in the following sequence.
1. Remove any large deposits of silicone or gasket material.
2. Apply silicone gasket remover and allow to set for several minutes.
3. Remove the silicone gasket remover. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4. Apply metal surface prep to remove any remaining traces of oil and to prepare the surfaces to bond. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
