Crankshaft Rear Seal with Retainer Plate: Removal

WARNING: This page is about a different car, the 2013 Ford Explorer. 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, may 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 plate, the seal and plate must be removed as an assembly and discarded.

NOTE: Cast aluminum (early build) shown in illustration crankshaft rear seal retainer plate, stamped steel (late build) crankshaft rear seal retainer plate is similar.

With the vehicle in NEUTRAL, position it on a hoist. REFER to JACKING AND LIFTING .
Remove the flexplate. Refer to FLEXPLATE .
Remove the crankshaft sensor ring.
Disconnect the CKP sensor electrical connector.
Remove the bolt and the CKP sensor.
If equipped with a cast aluminum crankshaft rear seal retainer plate, use the 303-519 T95P-6701-EH and 307-005 T59L-100-B to remove the rear crankshaft seal.
- Discard the seal.
Remove the 2 oil pan to crankshaft rear seal retainer bolts.
Remove the 8 crankshaft rear seal retainer bolts.
- If equipped with a stamped steel rear seal retainer plate, remove and discard the plate and seal.
If equipped with a cast aluminum rear seal retainer plate, install the 2 M6 oil pan bolts (finger-tight) into the 2 threaded holes in the crankshaft rear seal retainer.
- Alternately tighten the 2 bolts one turn at a time until the crankshaft rear seal retainer-to-cylinder block seal is released.
- Remove the crankshaft rear seal retainer plate.
NOTE: Only use a 3M Roloc® Bristle Disk (2-in white, part number 07528) to clean the crankshaft rear seal retainer plate. Do not use metal scrapers, wire brushes or any other power abrasive disk to clean the crankshaft rear seal retainer plate. These tools cause scratches and gouges that make leak paths.

If equipped with a cast aluminum rear seal retainer plate, clean the crankshaft rear seal retainer plate using a 3M Roloc® Bristle Disk (2-in white, part number 07528) in a suitable tool turning at the recommended speed of 15, 000 rpm. Thoroughly wash the crankshaft rear seal retainer plate to remove any foreign material, including any abrasive particles created during the cleaning process.
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 gasket 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 will cause 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 Motorcraft® Silicone Gasket Remover and allow to set for several minutes.
3. Remove the Motorcraft® Silicone Gasket Remover. A second application of Motorcraft® Silicone Gasket Remover may be required if residual traces of silicone or gasket material remain.
4. Apply Motorcraft® Metal Surface Prep to remove any remaining traces of oil or coolant and to prepare the surfaces to bond. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
