If it's something like a water pump, it's not even worth messing with. you can get a rebuilt one where it's already done for about the same cost in having repaired so no one really does it. Besides, you usually get money when you turn in your old one at some stores as well. (core charge)
How do you find dia meter of shaft when bearing no is given?
A shaft bearing is a low friction support device for a rotating member of a mechanical machine.
floating bearing allows axial movement of the shaft. fixed bearing does not allow for axial movement of the shaft
That is a bearing in the centre of a crankshaft or drive shaft.
A friction bearing is a solid bearing that directly supports the end of an axle. Friction is when the bearing and the joint are running together.
Use a die grinder with a cutoff wheel and cut the race in half taking care not to touch the shaft. If the bearing race spun on the shaft and froze on to the shaft chances are the shaft is damaged.
Bearing.
When pressing a roller bearing onto a shaft, the shaft typically has a tolerance or allowance that is slightly smaller than the inner diameter of the bearing to ensure a tight fit. This is often referred to as an interference fit, which ensures that the bearing remains securely in place during operation. The specific allowance can vary based on the bearing size and application, but it is crucial to follow manufacturer specifications to avoid damage to either the bearing or the shaft during installation.
To find the diameter of a shaft through a bearing number, refer to the manufacturer's bearing catalog or specification sheet. Look for the bearing's bore size, which represents the inner diameter of the bearing. The shaft diameter should match the bore size to ensure proper fit and functionality.
to remove carrier bearing, u will need to removbe the drive shaft from the vehicle the carrier bearing is bolted to chassis with 2 bolts . these will need to be removed and the carrier and bearing will come out with the drive shaft one drive shaft is out you can then knock old bearing and carrier off of shaft with a hammer. the old carrier is no good so doesnt matter if you trash it once you get old one off, carefully known new one onto shaft until seated,being careful to note which is front of carrier bearing you can then reinstall cariier bearing and drive shaft to truck. NOTE: now is a good time to check and replace if needed the U-Joints on the drive shaft
What about it?
You cannot fix a rod bearing. Bearings must be replaced. While it is possible to replace a single rod set, a bottom end overhaul might be the way to go. The rational here is that if one bearing is bad, how far off are the others? In addition, if crank shaft journal service is necessary, the machine shop will supply that correct bearing size after machining .
