How to Safely Service the Rear Crankshaft Seal on Mercury Grand Marquis?

Prior to servicing the crankshaft rear seal drivers must first deactivate the fire suppression system because it presents a danger of severe injury. Set the vehicle to neutral position on a hoist. Use the crankshaft rear oil slinger remover along with a slide hammer to remove the crankshaft oil slinger while the flexplate is not present on the engine. The installation process requires first using the crankshaft rear oil seal remover alongside the slide hammer for removing the crankshaft rear seal. Install the new crankshaft rear seal with engine oil on its inner lip before you use crankshaft rear oil seal installers to put it into place. Use crankshaft rear oil slinger installer and crankshaft rear oil seal installers to install both the crankshaft oil slinger. The installation procedure requires the flexplate and a fire suppression system repower with safety warnings along with other procedures for preventing serious personal injuries.

How to Service the Rear Crankshaft Seal on Mercury Sable?

Start the crankshaft rear seal servicing after positioning the vehicle in neutral on a hoist. Start by removing both the flexplate along with the crankshaft sensor ring. You need the crankshaft rear oil seal remover and slide hammer to take away and dispose of the worn-out crankshaft rear seal. All sealing surfaces require metal surface prep cleaning before proceeding. Engine oil should be used to both lubricate new crankshaft rear seals and the installation bore. Set the rear main seal installer against the end of the crankshaft and place a new crankshaft rear seal onto the tool. Proceed with the rear main seal installer while using the handle to insert the new crankshaft rear seal then continue with installation of the crankshaft sensor ring and the flexplate.
