Position the crankshaft rear seal and wear ring assembly on the Crankshaft Rear Seal and Wear Ring Installer base.
60. NOTICE: The plastic 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.
Insert the plastic step-up tool into the Crankshaft Rear Seal and Wear Ring Installer with the step-edge toward the installer.
61. NOTICE: 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.
NOTICE: Do not allow the engine to rotate during the installation of the crankshaft rear seal and wear ring assembly or damage to the crankshaft rear seal or wear ring may occur.
