Can't find spindle for 72"

[Scrubcadet10]

Read a little more carefully. It is a deck drive spindle and not a deck spindle.

Makes sense now, thanks StarTech.

Missing link. Deck model number SMST-72A SN C9000129. I think will solve the problem.

Lane you have the right PN ending in 1663. Btw Stens is nearly double what I paid for this spindle earlier this year.

I am going through a secure server in Germany but the forum should be able to turn the link into a live one.

Or can use the following link for the deck itself.

SMST-72A SN C9000001-C9099999

The last one I did, I had to almost completely disassemble the spindle to get it off. Me and the front end man just removed the seals and the bearings just a few minutes ago. Looks easy enough. He's well schooled on bearings and races.
The big bottom nut on this spindle is as tight as it'll go. No more adjustment on this. It's solid against the bearings and spacer (between the bearings).
So I'm gonna get new bearings, races and seals for it.

The customer is going to be happy about all this because he's been buying new spindles from the local dealer for about $200. Then paying me to put them on.

One question. Is that big nut supposed to be extremely hard to get off. Seems the closer it gets to coming off, the tighter it gets?

That nut preloads the the bearings. I can't remember off hande the preload torque. I think something like 150 in lbs. Look to see if the nut and shaft were staked to stop from backing off. Need to file the stake punches to free up the nut. Once you preload the bearings stake the nut.

The local parts store has a National Bearing "A-4" for about

Te heck with buying spindles now. Since I last posted, I not have 2 rebuilt ones sitting on the shelf, greased and ready to go. I called the customer and told him the price difference between what he was spending at the dealer, plus me installing it, vs me installing a rebuilt one, he was excited. I'm saving him at least $100. Plus I'm making more.

End result. Got the rebuilt spindle on, everything seems to work as it should. The only difference is sort of a high pitch squeal. I can't tell if it's a metallic squeal.
I did notice the belt is getting worn and has a couple of pretty deep cracks in it.

I greased it before I put it on, until grease came out of the releaf tab. I ran it, gonna grease it some more. It almost sounds like it's external, rather than in the bearings. But I know it's not a typical belt squeal.

How did you preload the bearings? Shaft turn smooth and easily in spindle when done?

I'm not sure how to "preload" them.

When I first installed it, it was too tights. So I backed the 1 1/2 nut off a little at a time, until it spun freely. A little less freely than the other. ( a tiny bit less) because the others had a little up and down movement in them.
