The crankshaft oil seal is probably one of the most important things under your hood. Its main purpose is to seal the openings on either end of the crankshaft—the front and the rear. It also helps maintain the crankcase seal, and while it is made from durable material able to withstand pressure, heat, and oil, this seal will wear out over time.

What is a crankshaft and what does it do? Of all an engine's moving parts, the crankshaft is the biggest and heaviest. There's no doubt about it, the crankshaft is the foundation on which the combustion engine is built. No part of the process – intake, compression, combustion, or exhaust – occurs without a crankshaft to put it into motion.

The seal on the rear of the crankshaft is being replaced. All rubber seals are checked and, if necessary, replaced. After inspection and proper maintenance, the part is returned to its place and the motor is assembled in the reverse order. After completing the procedure, the crankshaft should rotate smoothly, without much effort or jerking.

Fill the back side of the new seal and using a plastic syringe from a drugstore, or maybe you have a stock of your own inject it into the bearing a well. Clean off as much of the old grease first. You should need about 30-40 ml of grease. Use some sort of seal grease or o-ring oil on the lip of the seal and the crank.

What Does Crankshaft Sensor Do. The crankshaft position sensor measures the speed of rotation of the crankshaft and the position of the crankshaft at any particular time and converts it to the electronic signal. This electronic signal is then transferred to the ECU to calculate the timing of the ignition and the amount of fuel injection.

Both ends of the crankshaft extend beyond the crankcase, so some method of preventing oil escaping these openings must be provided. This is the job of the two main oil seals, one at the front and one at the rear. The rear main seal is installed between the rear main journal and the flywheel. It is commonly a synthetic rubber lip-seal.

Why Do Crankshaft Seals Fail? Over time the crankshaft seal dries out and becomes brittle, just like any rubber component. This may be due to the heat from the engine or from the friction it experiences between the crankshaft and the timing cover. Also, oil itself eventually degrades rubber vehicle parts. When the rubber loses its elasticity ...

The tolerance of the new spacer to the crank is miniscule. If it is not offered to the crank nose exactly square it will not go on. Do not force it. If necessary use the crankshaft bolt to move the spacer along the crankshaft. When seated, the spacer (blue arrow) should protrude slightly in relationship to the crank seal (red arrow).

The seal will transfer a layer of PTFE to the crankshaft surfaces that the lip will ride on. The transfer layer prevents wear while sealing better than a silicone or Viton material. If the seal is installed with a coating of oil, it will start to leak in a few miles.

What does the crankshaft gear do? The purpose of timing gears is to allow the camshaft and crankshaft to turn the timing chain. The crankshaft turns to move pistons up and down inside the cylinders. The camshaft turns to allow intake and exhaust valves on the cylinders to open and close. These components are important for proper engine timing.
