Where does everyone get their wheel bearing for 314-8 and 315-8 machines?  Any particular brand?

If you are talking about front wheel bearings for a 3/4" shaft these are hard to beat.

Some bearings today have one seal on the outside. These are greaseable through the fitting in the wheel hub.

 

Others have two seals - one inside and one outside. The inner seal will not allow grease into the bearing and if grease is applied the pressure will force the bearing out of the hub and off the spindle.

Best to remove the grease fitting and plug the hole with a set screw so grease can not be applied because once the bearing is installed you won't remember if they are greasable or not. Both types look alike on the outside.

Close examination will reveal the seals.

Since I had a couple of other brand tractors with sealed bearings, some time ago I started using them on my horses. It always bugged me that I had to use that huge amount of grease to fill the cavity -- and then to not feel really comfortable about whether the grease had actually went where it was supposed to!! And then theres that horrible mess when you have to open it back up!! Ive got a couple tractors that have the sealed ones in for quite some time and are doing fine. I have also changed a couple decks over to sealed bearings.

 

I usually prowl the bay and can usually find a package deal of 10 bearings for a really good price.

Do you need a press to get the wheel bearings in the wheel.

No just tap them out with a brass punch or hard wooden dowel

[pacer 3,175]

No, a hammer with a block of wood will do just fine

[peter lena 9,088]

no , a matching socket size ,of outer edge of bearing, can be easily tapped to reset a new bearing, don,t forget to add any of the spacer washers to the axle end to tighten up any sloppy play , washers are easily found at your local hardware store in the pull out drawer section , pete

The first thing I do when I get sealed bearings is use an oring pick to remove one seal and clean all the factory grease out and replace with good quality marine grade grease, I've found that the factory grease is not high quality and they don't put much in to start with, then if needed replace the seal or leave out if they can be greased from a fitting. The left bearing is factory right is new grease.

My dealer was out of the 1278 washer and the 28-2480.  Anyone know the sizes on these.  I need to run to Ace and see what they have that will work.

 

My dealer did have the 5210 washer shim.

Our Ace Hardware has a good selection of 3/4" washers in various thicknesses.

The small amount of grease in a new bearing is deemed acceptable. Reason being extra grease in a bearing run at high speed causes them to run too hot.

Have an application where grease is added to the bearings to expel moisture after each use. The grease fitting is then removed and replaced with a plug that has a small hole drilled in it. As the bearings heat up on the next use the grease is pushed back out and so far no more bearing failures. These are bandsaw blade guide bearings and the water is from the coolant/lubrication applied to the blade when sawing.

My electric motor guy came up with this solution. He claims the biggest cause of bearing failure in a 3650 rpm motor is someone added too much grease.
