In an engine block, crankshaft thrust bearings are placed into grooves formed in the block's webbing. Their purpose is to limit the crankshaft's forward and backward movement by keeping the crankshaft within a specific area of motion.

What does the thrust bearing do?
Thrust bearings support the axial thrust of both horizontal and vertical shafts. The functions are to prevent the shaft from drifting in the axial direction and to transfer thrust loads applied on the shaft.
What is a thrust bearing on an engine?
A thrust bearing is a particular type of rotary bearing. ... These are the type most commonly used in automotive applications (to support the wheels of a motor car for example), where they are used in pairs to accommodate axial thrust in either direction, as well as radial loads.
What happens if thrust bearing goes?
A worn thrust bearing has increased clearances between its rollers. This allows the bearing to move around in its seat excessively, which can lead to rattling, squealing or growling noises coming from the transmission. These noises are usually most noticeable when the clutch pedal is pressed down to release the clutch.
What do crankshaft thrust washers do?
Thrust washers are flat washers that are located between a rotating surface and a stationary component. They support the axial load or side to side motion on a shaft and prevent movement along that shaft.
What is a crankshaft thrust bearing?
In an engine block, crankshaft thrust bearings are placed into grooves formed in the block's webbing. Their purpose is to limit the crankshaft's forward and backward movement by keeping the crankshaft within a specific area of motion.
Can thrust bearings take radial load?
Thrust bearings should not be subjected to a radial load. They are designed for thrust/axial loads only. A standard thrust bearing is comprised of a brass or steel washer containing the balls sandwiched between two other washers which usually have raceways (ball tracks).
What is the difference between thrust bearing and ball bearing?
Axial bearings, or thrust bearings, are designed to withstand force in the same direction as the shaft. This is called an axial load, or thrust load. ... Radial ball bearings are designed to withstand forces that are perpendicular to the direction of the shaft, or radial loads.
What happens when a clutch thrust bearing fails?
The more worn down the bearing is, the harder it will become to depress the clutch pedal. It will soon get to a point where you cannot disengage the clutch. Then you won't be able to drive your vehicle at all since you won't be able to shift gears.
What causes a crankshaft thrust bearing to fail?
The causes of a thrust bearing failure can be traced to a single problem or a combination of problems. ... In general, though, one or more associated problems are usually to blame, including poor crankshaft surface finish, bearing overloading or bearing surface misalignment.
Can I drive with a bad thrust bearing?
The throwout bearing is part of the clutch assembly; specifically the part the clutch pedal pushes into the clutch assembly to lift the friction disc off the flywheel and disengage power transmission from the engine to the transmission. The engine of the car will run just fine without a throwout bearing.
What causes a noisy thrust bearing?
Symptoms of a failing clutch thrust bearing:
Rattling noise – A worn bearing can produce rattling noises. ... This is due to the worn bearing being unable to distribute even pressure onto the clutch plate, causing uneven contact with the pressure plate.
What happens if you have too little crankshaft end play?
On the other hand, if the endplay is too loose, it can cause thrust-bearing flange failure, crank thrust-flange damage, accelerated main-bearing wear in general, timing-gear and timing-chain wear and alignment problems, connecting-rod and piston-alignment issues (especially if the piston pins are pressed instead of ...
