Nissan 13510-6N200 Seal-Oil,Crankshaft Front

To replace the timing end cover oil seal, you have to first remove the crankshaft sprocket in the case. Take special care of the old position of the seal and remove it with a screwdriver or any suitable instrument provided that should not scratch the crankshaft surface. Otherwise drill two small holes at two opposite corners, put the self-tapping screws into the holes and use grips to pull the seal out. Examine the general condition and profile of the crankshaft seal's rubbing surface; if the face of a new seal is grooved or rough-finished, install it with slightly less interference to make it rub on shiny metal, not on worn lateg. To fit the oil seal, Nissan technicians use a special tool, which is a bar of a threaded rod with a metal tube and nut to hold the seal in place the tool must have a machined shoulder in it to align with the recess of the crankshaft. Nissan tool may not always be available but an RN can fabricate a similar tool when the Nissan tool is not available. Depressing the oil seal lips, scrapes the oil seal seating clean then using a punch presses the new seal squarely into place and using the depth gauge set to the specified depth as required by the applications. Once fitted, pull out the tool and the protector, reinstall the crankshaft sprocket again. For the flywheel end oil seal, one procedure is to first take off the flywheel, next put in a new oil seal with the proper tool for the job, and finally bolt the flywheel back on.
