How to install a rear Crankshaft Seal on Mazda 3?

The unitary rear main oil seal is forced into the rear main oil seal carrier that is attached at the back of the block. The transaxle and the flywheel/driveplate, then the oil pan should be removed. The second step is to unbolt the oil seal and carrier, then clean up the mating surface of the oil seal carrier on the cylinder block and the crankshaft, taking care to wipe off and polish any burrs or protrusions on the crankshaft which might have led to the failure of the oil seal. Slightly lubricate the inside lip of the new seal with clean engine oil and then apply a durable two-inch wide strip of plastic that is very thin and durable or cut two liter beverage bottle around the interior circumference of the seal and use it as a liner. Having the plastic seal liner/tool, insert the new carrier with the seal factory-fitted by inserting it in the contact area of the crankshaft by sliding it across. Bolt the oil seal carrier bolts in and finger tighten them whilst holding the carrier in place making sure that the bottom of the seal carrier is in contact with the bottom of the edge of the engine block so that it fits in perfectly and then tighten the carrier mounting bolts as poor fitting can result in leaks through the oil pan. Gradually peel off the plastic liner or tool to make sure that the new seal is touching the crankshaft mating surface in the proper position, and then screw the oil seal carrier to the required torque. The rest of the installation is in the needless reverse sequence of removal.

Mazda Crankshaft Seal

The Mazda Crankshaft Seal is applied to keep engine oil contained at the exit of the crankshaft to ensure that the motor operates smoothly and is protected from wear. Mazda dates back to 1931 and gained fame around the globe in the 1960s with the rotary engine and has built on efficiency with Skyactiv powertrains that wring more miles from each drop of fuel. The company combines the Kodo Soul of Motion design language with nimble handling that makes everyday drives feel like spirited excursions and its i-Activsense package adds smart aids like lane keeping and radar cruise to boost confidence on any trip. Mazda also plays around with electric drive, mild hybrids, and an adaptive all-wheel drive system that has been tested on rough roads, indicating a love of moving forward while keeping the fun high. Just as every car is a balance of style and substance, the Crankshaft Seal is a balance of strength and flexibility. This circular component makes use of a metal core and a rubber lip that hugs the spinning shaft to block the leakage that would cause a decrease in oil levels and an increase in friction. All engines throughout the Mazda range are based on this same simple design, although newer compounds provide longer service life. Because the Crankshaft Seal traps lubricant inside the crankcase, bearings remain coated, heat remains controlled and messy drips never ruin the driveway to help every Mazda deliver the spirited reliability fans love.

You'll get great performance and real durability when you pick genuine OEM Crankshaft Seal. Mazda builds these using high-quality materials and official factory methods to ensure they hold up mile after mile. You deserve that Mazda reliability without the headache of cheap knockoffs. It is easy to find exactly what you need in our huge inventory of genuine parts. Plus, every OEM part carries a real manufacturer's warranty for your peace of mind. You will love our low prices too. Order today and we will ship your brand-new parts fast. They often reach your door in just a few days.
