Crankshaft Rear Seal with Retainer Plate
Crankshaft Rear Seal with Retainer Plate
Removal
NOTICE: 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: This procedure is for removal of the crankshaft rear seal and retainer plate. If only removing the crankshaft rear seal, refer to Crankshaft Rear Seal Crankshaft Rear Seal.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the flexplate. For additional information, refer to Flexplate Flexplate.
3. Remove the crankshaft sensor ring.
4. Disconnect the Crankshaft Position (CKP) sensor electrical connector.
5. Remove the bolt and the CKP (Crankshaft Position) sensor.
6. Using the Crankshaft Rear Oil Seal Remover and Slide Hammer, remove and discard the rear crankshaft seal.
7. Remove the 2 oil pan to crankshaft rear seal retainer bolts.
8. Remove the 8 crankshaft rear seal retainer bolts.
9. 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.
10. NOTICE: Only use a 3M(TM) Roloc(R) 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.
Clean the crankshaft rear seal retainer plate using a 3M(TM) Roloc(R) 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.
11. NOTICE: 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.
NOTICE: Do not use wire brushes, power abrasive discs or 3M(TM) Roloc(R) 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 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 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.
Installation
1. NOTICE: Failure to use Motorcraft(R) High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
NOTE: The crankshaft rear seal retainer must be installed and the bolts tightened within 10 minutes of sealant application.
Apply 5 mm (0.196 in) beads of Motorcraft(R) High Performance Engine RTV Silicone to the 2 cylinder block/oil pan joints.
2. NOTICE: Failure to use Motorcraft(R) High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
NOTE: The crankshaft rear seal retainer must be installed and the bolts tightened within 10 minutes of sealant application.
Apply a 3 mm (0.11 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the sealing surface of the crankshaft rear seal retainer.
3. NOTE: Use the 2 oil pan bolts as handles during installation to avoid touching the sealant.
Install the crankshaft rear seal retainer at an angle above the oil pan flange to avoid scraping off the sealer. Tilt the seal retainer up and onto the rear of the cylinder block.
4. Install the 8 bolts and tighten in the sequence shown to 10 Nm (89 lb-in).
5. Install the 2 oil pan to crankshaft rear seal retainer bolts.
- Tighten to 10 Nm (89 lb-in) plus an additional 45 degrees.
6. NOTE: Lubricate the seal lips and bore with clean engine oil prior to installation.
Position the Rear Main Seal Installer onto the end of the crankshaft and slide a new crankshaft rear seal onto the tool.
7. Using the Rear Main Seal Installer and Handle, install the new crankshaft rear seal.
8. Install the Crankshaft Position (CKP) sensor and install the bolt.
- Tighten to 10 Nm (89 lb-in).
9. Connect the CKP (Crankshaft Position) sensor electrical connector.
10. Install the crankshaft sensor ring.
11. Install the flexplate. For additional information, refer to Flexplate Flexplate.
