Used to install the crankshaft rear oil seal and wear sleeve Contains: 303-770/1 Crankshaft mounting plate and nut. Usage Guideline: 1. Install the crankshaft rear seal and wear ring installer base and 2 bolts to the crankshaft flange. NOTE: Make sure the crankshaft alignment dowel fits in the dowel recess hole in the Crankshaft Rear Seal and Wear Ring Installer base or engine damage may occur. 2. Position the crankshaft rear seal and wear ring assembly on the crankshaft rear seal and wear ring installer base. NOTE: When positioning the crankshaft rear seal and wear ring assembly on the Crankshaft Rear Seal and Wear Ring Installer base, align it to the opening on the engine rear cover and manually start the crankcase rear seal installation. 3. Insert the step-up tool into the crankshaft rear seal and wear ring Installer with the step-edge toward the installer. NOTE: The step-up tool increases the flat surface area of the Crankshaft Rear Seal and Wear Ring Installer. Failure to use the plastic step-up tool during installation will result in damage to the crankshaft rear seal and wear ring assembly. 4. Using the crankshaft rear seal and wear ring installer, install the new crankshaft rear seal and wear ring assembly until the installation tool contacts the rear engine cover. NOTE: Do not allow the engine to rotate during the installation process. The crankshaft rear seal face and the wear ring must be flush with the rear engine cover or damage to the crankshaft rear seal or wear ring may occur. Oil leaks from the front crank seal are a very common problem on the 6.0L Ford compatible with Powerstroke Diesel Engine. The Ford special tools required for this job require 3 hours book time to use following the factory procedure. Using our wear ring installer and procedure the job can be performed in about an hour. Unlike the factory method, our tool does NOT require removing the radiator, fan, and shroud. The job is nearly impossible to perform without an installation tool due to the delicate nature of the wear sleeve, the location of the harmonic balancer dowel pin, and the fact that the wear sleeve must be driven to a specific depth beyond beyond flush to position in properly. Attempts to install the sleeve without correct tooling usually result in leaks and comebacks. Front Crank Wear Sleeve Driver/Installer Kit Tool with Sleeve & Seal Fitment: Fit for 2003-2010 Ford compatible with Powerstroke 6.0L Replacement: Motorcraft/OTC 303-761 Material: High quality steel and rubber with durable How to Use 6.0L compatible with Powerstroke Front Crank Wear Sleeve Driver/Installer Kit Tool with Sleeve & Seal Begin by breaking loose the four front crankshaft dampener bolts. Then remove the belt. (The belt just needs to be slid off the upper idler pulley to allow enough slack to remove the crank pulley.) Finish removing the bolts and the front pulley. Fan, shroud, and radiator are shown removed for clarity, but removal is not required. Remove the five 10mm bolts that attach the oil pump cover and crank seal. With the cover removed, clean the oil from the area around the pump. Tape the area as shown with wide masking tape to prevent debris from getting into the pump gears. Use a small cut off wheel to carefully cut through the old wear sleeve (if present) and remove the sleeve. Clean the crankshaft – fine sandpaper may be required. Install the new wear sleeve into the tool and coat the inside of the sleeve with a light layer of red Loctite. Slide installer and sleeve onto crankshaft Lightly tap installer with a hammer until it bottoms out. Remove installer – your sleeve is now installed to the correct depth. Remove tape, clean surfaces thoroughly, and apply some engine oil to the pump gears. Install new seal into pump cover and complete reassembly.
