Your spindles look exactly the same as mine. I wouldn't mind just putting all new parts into it, but, that gets expensive in a hurry, and is a major undertaking on the 72" deck. I just don't have the scratch for that kind of behavior.
(much as I would love to.)
Well, yes, the spindle shafts cost about $68.00 each.
But how long will it take to equal that in replacement bearings every few years? And your time and effort?
Again, my deck was bought new and went over 500 hours/14 years before needing the spindles overhauled.
If we assume the overhaul will last 14 years, lets call the shaft and bearings $100 per spindle, divided by 14 years = $7.14 per year per spindle.
I checked some prices on genuine Timken #14 sets, about $15 each or $30 per spindle - I'm sure there are cheaper brands but.......
If you have to replace them every two or three years, that is 5 replacements x $30 = $150 per spindle, divided by 14 years = $10.71 per year per spindle.
I think I will save both my money and my valuable time over the long run.......
Changing the shaft is no more work then changing just the bearings?
The bearings, races and shafts are the only needed parts? The metal seals do not go bad unless the thing really blows up?
When you are changing these bearings are you changing the race? If not, you are asking for them to fail early.
