What steps are involved in removing and installing a rear crankshaft seal on Nissan 350Z?

The transmission must be removed from the vehicle for this procedure. Carefully pry the old Crankshaft Seal out of the block with a seal removal tool or screwdriver, ensuring to do so gently to avoid damaging the crankshaft, as any damage may cause the new seal to leak. Apply multi-purpose grease to the crankshaft seal journal and the lip of the new seal. It is preferable to use a seal installation tool to press the new seal into place, taking care to work it onto the seal journal of the crankshaft without rushing, as the lip is stiff and can be damaged. Install the seal squarely and only until it is flush with the back of the block, no further. The remaining steps involve reversing the removal process.

Nissan 350Z Crankshaft Seal

The Nissan 350Z Crankshaft Seal is located at the front of the engine. Its primary task is to prevent the leakage of engine oil out of the crankcase so that the engine is well lubricated. The Crankshaft Seal is made out of a round shape of a mixture of metal and rubber to create a tight fitting cover over the end of the rotating crankshaft with the purpose of maintaining the oil pressure constant. This barrier is applied in the 350Z to minimize friction and wear of the moving parts by ensuring that the oil remains in the right passages. The seal is under continuous movement and hence, a worn Crankshaft Seal may cause oil to drip out at the front of the engine, resulting in visible leakage below the Nissan sports car. High mileage or observable spots of oil around the component drive section of a 350Z may be an indication of a Crankshaft Seal that has worn out and requires some attention. This is a small but important component that maintains the Nissan engine with clean oil. A new Crankshaft Seal helps to sustain a smooth running engine and the life of the components. Regular inspection for oil seepage around the harmonic balancer area of the Nissan 350Z makes it easier to spot early seal wear before significant oil loss occurs.
