  A: To replace the Crankshaft rear oil seal, firstly, remove the engine Flywheel, and ensure Crankshaft rear oil seal leak without harm to the Crankshaft od surface or the chamfer with a flat-bladed tool. Use a small flat bladed tool to pry out the Crankshaft rear oil seal by angling it through the dust lip, operate the handle movement towards the end of Crankshaft, repeat as needed. Check the id on the bore and correct or replace the Crankshaft rear oil seal housing if necessary and check the crank for nicks or burrs on the surface that contacts the seal, repair or replace the crankshafts as needed. For installation, apply engine oil to the both inside/outside diameter of the new Crankshaft rear oil seal, then install it over the mandrel until it stops against the collar of the j 38196 rear Crankshaft seal installer (J 38196). Mount the j 38196 onto the Crankshaft by hand or tighten screws to 5 nm (54 inch lbs) and spin the handle of the j 38196 to force the seal in the bore while collar is tight against the case, making it consummate. Loosen the t-handle until it stops in order to position the collar for installing more new Crankshaft rear oil seal to attach the attaching screws.
