    Q:
    How to Service the Rear Crankshaft Seal on Ford Escape? Posted by Customer
    A:
    Start the crankshaft rear seal service by placing the vehicle in NEUTRAL position on a hoist. Pull out the flexplate or flywheel before extracting all engine oil and installing the drain plug with a torque of 28 Nm (21 lb-ft). The entire process of removing the oil pan becomes essential since it protects the rear oil seal retainer joint from damage; thus 17 bolts need to be taken out. You need to take off the six bolts which anchor the crankshaft rear oil seal with its retainer plate. The Crankshaft Rear Main Oil Seal Installer helps install the crankshaft rear oil seal with retainer plate onto the crankshaft by combining with torque the specified bolts to 10 Nm (89 lb-in) while following a specific bolt tightening sequence. A plastic scraping instrument should be used for cleansing sealing surfaces in order to stop scratches that might trigger leaks. Uncapped oil pans must be cleaned of the sealant so the specified surface preparation process for metal products can take place following complete drying. Stipulate the appropriate procedure which consists of using a 2.5 mm (0.09 in) bead of silicone gasket and sealant to the oil pan followed by bolt installation finger-tight then full-tightening to 10 Nm (89 lb-in). The final step includes installing all remaining oil pan bolts while following the specified tightening sequence to 25 Nm (18 lb-ft). Then reattach the flexplate or flywheel before putting clean engine oil into the machine.

    Q:
    How to Service the Rear Crankshaft Seal on Ford Fusion? Posted by Customer
    A:
    Begin the crankshaft rear seal servicing operations only after the vehicle sits in NEUTRAL on a hoist. Empty engine oil before installing the drain plug which should be tightened to 28 Nm (21 lb-ft). To protect the rear oil seal retainer joint from damage the 16 bolts and stud bolt along with oil pan must be taken off. You must disconnect the 6 bolts and remove the crankshaft rear oil seal together with its retainer plate. Affect installation requires using the Crankshaft Rear Main Oil Seal Installer to mount the crankshaft rear oil seal with retainer plate onto the crankshaft along with correct bolt torques to 10 Nm (89 lb-in). The use of metal scrapers along with abrasive tools should be prohibited for sealing surface cleaning operations since plastic scraping tools should be used instead. The mating surfaces of the oil pan alongside the engine front cover and cylinder block need thorough cleaning before inspection. After applying sealant to the oil pan it should be secured within 4 minutes or else the operator must remove the sealant followed by cleaning and drying the surface area for at least 4 minutes using metal surface prep. Depose 2.5 mm (0.09 in) of silicone gasket and sealant onto the oil pan before installing the oil pan and securing its 2 bolts lightly. First install the 3 bolts and stud bolt before tightening them to 10 Nm (89 lb-in), then proceed with tightening the remaining oil pan bolts in sequence to 20 Nm (177 lb-in). The flexible part and mechanical wheel should be reinstalled and the power unit should receive appropriate clean engine lubrication.

    Q:
    How to Service and Repair the Main Bearing Crankshaft Seal on Ford Focus? Posted by Customer
    A:
    A hoisted vehicle in NEUTRAL position should be used for crankshaft main bearing seal servicing and repair work. Open the flywheel or flexplate before removing all engine oil from the compartment and installing the drain plug fastened to 28 Nm (21 lb-ft). Move on to the following step by removing the oil level indicator together with its tube. Removing the 17 bolts from the oil pan will prevent any damage to the rear oil seal retainer joint. You must remove six bolts securing the crankshaft rear seal along with its retainer plate. To install the crankshaft rear oil seal with its retainer plate the Crankshaft Rear Main Oil Seal Installer helps place the new components over the crankshaft before securing them using 6 bolts that need to be torqued to 10 Nm (89 lb-in) following a particular installation order. A plastic scraping tool should be used to clean the sealing surfaces but if the sealant remains unsecured for more than four minutes it must be removed before cleaning the area with silicone gasket remover and metal surface prep. Apply a 2.5 mm (0.10 in) bead of silicone gasket and sealant to the oil pan before securely installing 2 bolts by hand and torquing the 4 front cover-to-oil pan bolts to 10 Nm (89 lb-in) and the rest of the oil pan bolts to 25 Nm (18 lb-ft) according to the specified sequence. Place back the oil level indicator together with tube before reinstalling the flywheel or flexplate. Completing the procedure requires adding clean engine oil to the engine.
