Product Description

?

Genuine Manufacturer Sourced replacement part used on a variety of Power Tools. This part is made out of Metal and it is sold individually. Ball bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.

Bearings were worn out and noisy

This was about a 2-3 hour process. Could have been less if I had jigs to removing and setting the bearings already, but I had to cobble together a setup using scrap wood and metal.

1. Unplugged the tool!
2. Removed the blade
3. Loosened the belt tension. Loosened two bolts that secured motor on pivot and lifted up . Removed belts one at a time (there are 3)
4. Removed spanner nut and arbor nut on the back of the shaft. When doing the arbor nut you need a wrench for the blade-side and a socket for the other side. Remember, the nut is reverse-threaded! Righty-loosey, lefty-tighty in this case.
5. After those are loose, tapped the non-blade side of the shaft with a rubber mallet to extract it.
6. There was one bearing still on the shaft, and one bearing in the assembly. The one of the shaft had to be removed with an arbor press and creativity (it is difficult to get up under the flange, need to use a wrench or couple pieces of steel and bang on those). The bearing that was still in the assembly just comes out, but you may need to tap it from the other side if it\'s stuck.
7. Once bearings are removed (which is the longest part of the process), put the new one on the shaft. When installing the new ones, make sure to only put force against the outer ring/race of the bearing where it is strongest. If you hit the cage/shield, you will mess up the bearings as it is soft metal there. Just be patient and clever.
8. Now the tricky part, reassembling the shaft assembly. Look at the diagram for which parts to put on first.
9. Once all the shaft parts are in place, tighten down the spanner nut to lock the loose bearing in place.
10. CRITICAL: Put arbor nut on, but DO NOT wrench down on it. Just get it to meet up with the end of the thread. Putting any amount of torque on it after it has met a surface will compress the bearings in a direction they are not meant to handle force, shortening the lifespan of the bearings. This is the second time I\'ve reinstalled the bearings in 6 months and talking to an expert convinced me that is the issue we\'ve been having.

The bearings that are installed now are already sounding gritty again, whereas when they were freshly installed they were quiet as a mouse. Take care in reinstalling because it will determine how long your bearings last.

Saw made squealing sound, vibration, and slight wobble in blade initially.

1. Removed rails and extension table.
2. Removed saw table top (as 1 piece). Make note of any shims under the table top when lifting it off.
3. Removed belts by loosening saw motor.
4. Removed arbor assembly as a unit.
5. Replaced both bearings, spacers, and load spring. The arbor shaft has a left hand threaded nu t on the end that required cutting off as it was so tight. I would recommend ordering a new nut.
6. Reinstalled arbor assembly. (Turn tilt adjustment wheel to aid in getting assemble aligned properly. Lubricate all parts to ease installation and don\'t try to force any of the mating parts.
7. Reinstall all other parts in reverse order (3-1)

Remove the cutterhead from the jointer. Remove the pulley from the cutterhead by loosening the set screws and pulling on the pulley and removing the shaft key. Use a bearing puller to remove the old bearings. Then use a socket the same size as the inner race of the new bearing to tap the socket with the hammer, to seat the bearing on the cutterhead. Then install the pulley and the cutterhead back on the jointer.

1. Loosen the motor belt tension

6. add the new side bearing on too

Wasted one hour trying to ta ke the ball bearing out by simply using two metal plates and a piece of wood an hammering it. Borrowed my brother\'s ball bearing puller and took only 25 minutes to assemble after that.

I try to figure out why ball bearing was wore out within a year after 15 years. So, I did put some lubes around two ball bearing. I might hope these bearings keep longer running.

Time consuming part of the job was taking apart the saw with extensions on both sides and front, then lifting off the actual top. Fairly straight forward getting the belts off then removing the shaft after that. Took pics to remember how the spacers and washers went, replaced the bearings and proceeded to reassemble. Works great.
