Nissan 13042-D0100 Seal Oil CAMSHAFT

Further to the removal of the crankshaft oil seal, the negative cable on the battery must be removed followed by securing it away from the terminal. Then, correctly unbolt the fan shroud, fan assembly, drive belts, pulleys, the vibration damper and timing belt. Remove the crankshaft timing pulley with two screwdrivers, if this doesn't work apply enough force and if that does not work, take out the timing pulley attaching bolt and thread it into the crankshaft to provide a pillar for the puller. After removing the pulley, override the timing belt plate, then using a screwdriver; push out the front oil seal. Glaze the inside of the new seal with assembly lube and fashion a seal installation tool from a piece of pipe about 30 cm long and the end should be polished. Force the new oil seal into its position using the tool until it is in the correct position and embedded firmly in the rubber boot. Place the timing belt plate back on its respective position over the crankshaft and fit the Woodruff key into the lark slot, this is followed by applying assembly lube to the crankshaft timing pulley before sliding it over. In the case of the camshaft oil seal, undo the following procedures then tight the camshaft pulley using a screwdriver as you un-screw the retain bolt. Disassemble the pulley and, if both are being exchanged, do not confuse the gears. Therefore, take out the old oil seal and use the same installation tool to press a new one onto the section. Remove the lock-washer and tighten the camshaft pulley retaining bolt until it is finger tight and then lock it in place with a screwdriver again.

To remove the lifters, start by removing the valve cover and rocker arm shaft assemblies. Secure the lifters with rubber bands to prevent them from falling out of the guides. Remove the lifter guide assembly and then remove the lifters from the bores one at a time, keeping them in order. Avoid laying the lifters on their side or upside down to prevent air from becoming trapped inside.

If the endplay exceeds the specified range, measure the old plate and obtain a new one to bring the endplay within specification.

Reinstall the rocker arm shaft assemblies and valve cover, then bleed air from the lifters by running the engine at 1,000 rpm under no load for about 10 minutes. Afterward, remove the valve cover and rocker arm shaft assemblies again, and repeat the plunger check. If air remains, replace the lifter.
