Nissan 13510-1KC1A Seal-Oil,Crankshaft Front

The timing chain cover oil seal can easily be replaced by first, removing the crank shaft pulley. With caution pop the oil seal up with a large flat-bladed screwdriver, avoid scratching the crankshaft or the timing cover. Scrub the seal housing and smoothen any ridges on the housing where the seal had difficulties holding on to. The lips of the new seal should be lubricate with clean oil and should be inwards while the seal should be inserted gently such that it does not get damaged. Bolt off the crankshaft pulley again, and drive the seal until it sits against the timing chain cover before washing off the oil residues and reattaching the crankshaft pulley. For the flywheel oil seal, the flywheel is then removed then using grip or pries the oil seal is pulled out with care being taken if a self tapping screw is to be used should it bite into anything other than the seal. Enter the seal housing and just wipe it clean in addition to the use of abrasive paper to smoothen any sharp edges. Wipe the lips of the new seal and the crankshaft shoulder with clean oil and then, position the lips over the crankshaft shoulder and firmly push it into the inserted cavity. With the seal still protruding, spread the liquid gasket sealant to the outside edges and then driving the seal to be flush with the cylinder block and should be wiped clean of any excess sealant. Lastly for the flywheel, their be remnants of oil or sealant, therefore they should be washed off and the flywheel should be re-fitted with the right seal.

Install the seal with the seal lip toward the engine and the dust seal toward the transaxle. Tap the seal into place using a seal driver to ensure it doesn't become tilted.

Use a puller to remove the pulley from the crankshaft, ensuring the proper adapter is used on the end of the crankshaft to prevent damage, and that the jaws of the puller are secured to the hub of the pulley.

Ease the seal into position without damaging it and drive the seal until it is flush with the timing chain cover.

If the Nissan tool is unavailable, a similar tool can be fabricated.
