Krause disc help

[Jcattleco]

Trying to replace a shaft and bearings on a Krause disc, tag is old so the only numbers I have show A3213 and a number 4 on the bottom

Already called shoup they can make me a axle but don’t have the flange bearings,
My shaft is measure 1 1/8 and my bearings id showing 1 3/16 , only other numbers I can fine are on the spools showing 212-0-7A which I’m needing one of those also and the smaller spools around one side of the bearing

If your disk looks close to this one, it's most likely one of the 400 series.

This one is a 10' model 408.

The spools on mine are the same number as yours.

The bearing ID, for whatever reason, is an 1 3/16".

If you get the bearing, go with the W208PPB7 instead. It's the same thing for a fraction of the cost. Why the cost difference now, I have no idea. Both bearings were around $12, 10 years ago & now the one pictured is around $126 & the W208PPB7 is around $14 on eBay. ¯\_(ツ)_/¯

I have one of the 10 ft models also, the axles are 54 in and have had no luck finding one, shoup will custom make them for $179 each which is more than I'm willing to pay I can buy one longer and cut it off and weld a 2x2 square cap ,

any other locations that sell 1 1/8 round axles?????????????

Vee it out and weld it back together or if just got grooves from loose shaft just weld them up and grind back so a disk or bearing will slip over it again. As for he bearing if there is no sleever that goes between the spool sections with the bearing for spacing I would have no idea why the shaft is 1-1/8 and bearing is 1-3/16 unless it is to fit to the spools better some how. A big impact works well for loosenig and tightening back up We did the disk rear half this past spring and an 1 inch impact with 175 PSI was good for that and we would hith the back end of the shaft as we tightened the nut. None came loose since doing that. It has 1-1/2 round shaft.

I could salvage one of them , but its still got a couple bends in it.
possibly another, but 2 were non usable.

yes, the impacts are great, i use a Milwaukee impact. sure saves a lot of arm work.

I heated a couple of ours with the torch and put it in the press and straightened it with a half inch bend in it. It has been back in use for 2 years and the other for one year. My impacts are all air except the one small 12volt Milwaukee. IT works good for roofing screws on steel roofing. And the drill is alright just battery is the worst part always dead when you need them most. I don't have much interest nor use for cordless tools. I also used old disc blades for shims with a hole cut in them for the shaft since they were old smaller disc blades with the square hole in them. Also used them along the shaft between the disk and spool to make up for any wear there may have been in a spool or disc blade. Outside was bigger than the spool only a wee bit and fit the shaft just a bit loose so it did not bind on the shaft. Once tight they have been no problem.
