    What kind of mower do you have? What problems are you having? Some spindles have clips holding the bearings in. Some bearings are pressed in. More details dude.

    Hi Richard, well run scag turf tigers, have couple spare spindels to replace bearings. My prob is I cant stop the shaft from turning while socket on other end nut. Vice is so tight but still turns not allowing nut free.

    Hmm.. Have you tried heating up the nut first? Have you sprayed the nut with PB Blaster or WD40 and let it sit for a few days? How about an impact gun?

    Be careful if you decide to go the "heating" route. Most people seem to think that they have to turn the nut red all the way around when heating. This only makes the nut seize tighter. Applying heat to one side of the nut only will cause the nut to expand to where it can be loosen. Once the nut has loosened to where it is no longer stuck, it is best to apply WD40, PB Nut blaster or similar and let cool off before removing. As the nut cools it will draw the oil down the shaft and around the threads. This prevents galling of the threads, sometimes on the shaft or nut or both.

    No go, tried gas heating up and impact gun at 120 psi and has turned only 5 threads in 1 hr.
    Shop had many probs way back and see why.
    Starting to scare shaft in vice.

    See if you can get it to move back down the threads at all. Sometimes you have to loosen it a little and then tighten it a little and work the nut off that way. You can also use a nutsplitter or a sharp chisel to cut the nut. Either way when/if you do get it off you should replace the nut and rethread the shaft. If you're going to replace the shaft get the nut up a little bit and then cut the shaft. It sounds like the nut was crushed by using too much force to install it or it was crossthreaded.
