Where is the crankshaft thrust bearing located?
Where is the crankshaft thrust bearing located?
Crankshaft thrust bearings provide a fore/aft gap-control for axial movement (or endplay) of the crankshaft. These thrust bearings are located at a specific main bearing location, generally at the center main or rear main, depending on engine design.
How long does a thrust bearing last?
If the noises are caused by the release bearing, it will be faulty and it’s not uncommon. It could be 3 years or 20 minutes if it was that long.
What kind of bearings do I need for thrust clearance?
Testing thrust clearance requires bearings in at least the Number One and Five journals to properly support the crankshaft. With the main cap in place lightly tap the crank from behind to align the two bearing halves. This particular photo happens to be of a small-block (right).
Is the journal bearing part of the thrust bearing?
The thrust bearing incorporates both the journal bearing as well as fore-aft thrust surfaces. It is this clearance we will be addressing in this article. With a completely disassembled engine, the first step in this process is to ensure that the proper main bearings are used.
How do you set the thrust cap on a push mower?
With the bearings and crank in place, set the main cap in place and lightly set the thrust cap with perhaps 10-15 lb-ft of torque on the bolts. Using a rubber mallet, tap the crank forward. This will align the two thrust bearing halves at the rear. Now torque the main cap bolts/studs with the oil pump, if so equipped.
How to replace an automotive engine front crankshaft seal?
1. Disconnect the battery Anytime you are working on the engine front there is the potential of creating short circuit if you touch a wrench or any metal piece from battery power to ground. To prevent this remove the negative cable of the battery to stop the electrical power to the car. 2. Remove the Serpentine Belt

What should I do if my crankshaft bearings are not aligned?
Tighten main cap bolts to approximately 10 to 15 ft.lb. to seat bearings; then loosen. Tap main cap toward rear of engine, with a soft faced hammer. Tighten main cap bolts, finger tight. Using a bar, force the crankshaft as far forward in the block as possible; to align the bearing rear thrust faces.
What happens if you have a thrust bearing failure?
A thrust bearing failure sends contaminants throughout the engine. If not remedied quickly, the failure will result in se- vere damage to the crankshaft and main thrust cap, and further scoring damage to most or all internal components. This big-block Chevy rear main cap from an early-generation 454 experienced a severe thrust bearing failure.
