spindle bearing replacement seals...

Howdy all!

Long-time lurker, 1st-time poster here... I have a 2007 Bad Boy 60" ZT mower that I've purchased Timken bearing replacements for the 3 spindles (didn't want the same Chinese one's that were in there, and didn't want to pay $20-$25 ea. for 6 of them) and found that each of the new bearings have only has 1 seal with it. Needless to say, I've searched the I-net over and cannot come up with replacement seals and would greatly appreciate whatever help you have to offer. Here's all the numbers I could find on the Timken bearing and packaging:

30X62X16 = bearing measurements
206F = on the bottom of the box with bar code
A039315347 = shiny additional Timken sticker on box
6206RSR = on seal
W613 = on seal opposite 6206RSR

Thanks!

Sooo...... You bought new bearings that only have a seal on one side ?

If so...... Do yourself a favor, Drill a 1/4" hole in the side of the spindle housing then tap it and insert a grease zerk. Install the bearings open side inward then you can keep the spindles greased and get longer life out of them......

That's the way the best spindles in the industry are made. You cant expect the drop of grease in a sealed bearing to hold up long under the conditions we put them through. Just go easy on the pumping. You only need to pump until you see the seal move ever so slightly. Too much and and you will destroy the seal.

I thought about that and still might do it... My issues are (1) had spindle issues while under warranty and found that only 1 of the 3 still have the internal shaft spacer / collar installed (would need to fill the whole spindle with grease? and (2) the inside of the spindles are pretty rusty / would take a fair mount of work to get them clean.

It just seems like a lot to do when all I really need are seals, and of course the website didn't state whether the bearing was completely sealed or not when I purchased them...

Tapping / zerc fitting is still under consideration though...

I can tell you they won't last long with only one seal and rust flakes coming down on them. Filling the cavity with grease is not a bad thing. It will absorb all the heat generated and ensure contaminants never reach the bearings.

Other greasable applications I've worked with before we'd remove the zerk fitting when done and install a plug in it's place... I'd assume it's also advisable here to keep them from being broken off by flying rocks, sticks and such?

Not likely. The only time I've seen that is when they put the zerk for the caster forks facing forward. Usually gets taken off when you bump the trailer. I just wipe them off with a rag before I attatch the gun. Leaving it in also let's you apply a little positive pressure in the cavity which helps keep out water.

More-n-more it's sounding like I need to do some wire-wheeling, drilling-n-tapping...

I'm kinda' fond of Lucas Red-n-Tacky #2 grease and that's the tube I've got in the gun now... Is it safe to assume it's good for this application also?

That's really good grease. I use it on my dirtbikes and dads snowmobile. Anything from Lucas is a quality product. Just don't switch to a different grease. Mixing them can cause problems.

So are you advocating the second seal? Or just a good cleanout of the spindle innards?
