Interesting Video On Mower Deck Spindles

I致e watched some of this guys fix it videos and he痴 good. Take a look at this simple bearing hack. It really does make you wonder why manufacturers do the dumb things they do.........enjoy

Yeah...sealed bearings where a zerk is suppose to grease them. My old Cub Cadet has 1" blade shafts with tapered roller bearings and they will out last me.

The top bearing still doesn’t get any grease in it. If you pumped the cavity full of grease to actually push grease in the top bearing then you’re going to push the seals out. I think quality sealed bearings are the better way. Maybe an oil filled cavity with a splasher on the shaft to throw oil on the top bearing would be the best solution.

Yep, so now you can pump the seals out with grease and allow the dirt to get in. Oh, and good luck putting the nut back on those threads you just hit with a hammer. JEEZE!!!

Hitting the bearing out with a steel punch directly to one side of the bearing is a sure way of putting a small bulge in the bearing limting its life bearings deform when hit with hard objects if you have to hit the bearing to get it out replace it with a new one

They just cut right off with a utility knife. As for tearing them up knocking them out I see this more as a when you replace them option. No dirts going to get in either as you are only cutting one side . That’s the side that goes in the spindle where it’s protected.

Or you can just pop the seal out with a dental tool. The idler wheels that have no zerk can be greased this way. Pop the seal out, pump grease between the bearing balls with a needle tip, install the seal again.

And no safety glasses.... Side impacts to most ball bearings makes them fail ASAP.

A claw hammer no less............

LOL, you would be surprised how many would put sealed bearings in again and continue to put grease in zerk...

I notice that on pillow block bearings but never thought it applied to deck spindles.

So how many deck spindles are like that? Some, most, a few?

I thought the video was going to mention the belt ripper that my JD belly deck had. Little tabs under the spindle pulleys probably designed to shed debris, but would make short work of an expensive belt if it popped off.

The Deeres like that have sealed on the top and open in the bottom. His was apart before I'd think. I still replace lots as people wash them. That being said, there are spindles you pull apart and they still have the seals intact.

There is a reason to grease spindles with sealed bearings. It keeps water out of the spindles and cools the bearings.

Maybe so in most homeowner mowers, however in a commercial mower like (Kubota F3060 for example), the deck spindle upper seal is "VHY dust seal, no spring" and will be installed lip pointing up.

I.E. it will let out old grease as needed.



Upper


The lower seal is a SB type (with spring), and will be installed lip pointing up.

The grease fitting is at the top end of the spindle shaft.

PS. These roller bearings are the same size & type as a very common boat trailer wheel bearings are!

I pulled a spindle from the x744 62c deck and the bearings had no seals. Instead, the separate seals were mounted outboard of the bearings and they rode on a bushing. Bearings top to bottom were well lubed and looked like they should last for a long time. (similar to the above ^ drawing) The deck on the CC 982 has tapered roller bearings and will outlast me.

Not familiar with these - which brand are they?

Mine exploded a few weeks back.. I bought one thru the "Walmart" site & don't remember where it came from.{co. name}
It DID have a grease fitting on it.. So I greased it & installed it..
& like everybody does, I gave it a spin before putting the belt on..
That sunofab. wobbled about 1-2 inchs.!! so I took it back out & started swapping parts from the old one..
I got all the way down to THE SHAFT.!! I put the old shaft in & the "wobble" went away.!!
THAT was amazing.. that shaft is about 2-3 inches if solid steel.!!??
Anyway, I cleaned up the old shaft & reinstalled the Franken Spindle assembly.. All is good..
