The upper crankshaft bearing and lower crankshaft bearing is a critical components in a car’s engine, located on the top of the crankshaft and responsible for supporting the rotating weight of the crankshaft. Wear and tear on the bearing can lead to reduced engine performance, poor fuel efficiency, and eventually engine failure. Regular maintenance, such as oil changes and bearing replacements, can help extend the lifespan of the bearing. If you notice any unusual noises or vibrations while driving, it may be a sign that the bearing is failing and needs to be replaced.
Thrust bearing: OE part number:4946031
What is a camshaft push support?
You will need to hold the roller cam to the rear when using it. The cam thrust button is located between the front of the timing gear and the rear of the front cover to ensure proper end play.
What is the result of a failed thrust bearing?
The thrust-bearing surfaces will be damaged if there is not enough clearance. They can’t keep a sufficient amount of oil on them and they’ll overheat.
What are the signs that my thrust bearing may be bad?
The clearances between the rollers of a worn-out thrust bearing have increased. The bearing can move excessively in its seat, causing rattling, growling or squealing sounds to come from the transmission. The noises are most obvious when the clutch pedal has been pressed to release the transmission.
