Removing bearing if shaft is too long.
I need to remove a bearing from a motor shaft. My Posi Lock puller,
unfortunately, does not have enough reach to grab the bearing because the shaft is too long. Is there something that can be easily done. I did have to make some makeshift tools to remove the pulley, but this is a different case because pulley had holes in the back. -- Due to extreme spam originating from Google Groups, and their inattention to spammers, I and many others block all articles originating from Google Groups.

Do you want to save the bearing? If not, find a piece of pipe that will slip over the shaft. Weld a plate/nut on one end for a pusher bolt. Slip it down to the bearing and weld the pipe to the bearing. Turn pusher bolt. If it's a larger bearing I just torch them off.

Notch one cap to fit over the shaft behind the bearing, screw on the pipe, put a hose clamp around it to keep it on. Tap the other end cap for threaded rod. Jim Wilkins |

How long is too long? Can't you make a longer extension ( the links that
limit your puller reach) for your puller to temporarily replace the original one? Motor bearings don't normally require much pulling force to slide them out so a DIY puller replacement links made out of small flat bars should work. But, if you are not skilled enough to do basic drilling and cutting of metals my suggestion won't be of much use to you.

Removing bearing if shaft is too long.
Several possibilities;
1. heat the bearing until it slips or can be easily driven off. 2. Cut the inner race with a cutting torch with the flame aligned with the shaft axis 3. cut the bearing outer race off, remove balls/rollers and cut the inner race diagonally with a 3" cutting disc. I use #s 1 and 2 the most. JR Dweller in the cellar Ignoramus17809 wrote: I need to remove a bearing from a motor shaft.

Pull the bearing off the other end, the shaft is shorter there. |

I'ld have to see the exact nature of what you are pulling, but I have pulled
bearings and/or busings off a shaft with my hydraulic press. I slid a steel plate in behind the bearing on each side and pushed the shaft out. Since I have switched to an air operated jack on my press this goes pretty quickly. |

We almost always cut them off with a die grinder & cutoff wheel, but I once saw a old Chief simply shatter one off with a hammer & chisel in a matter of seconds with no damage to anything (except to the old bearing).

.. My Posi Lock puller,
unfortunately, does not have enough reach to grab the bearing because the shaft is too long. Is there something that can be easily done. When I have this situation I go to a local automotive machine shop. They have a press that will handle 4 foot shafts for situations like yours. I hand them a 5 and they are happy. A cold case of beer on a Friday afternoon is also acceptable. Bob AZ |

Hydraulic shop press, and the right two-piece bearing press jig. This is the perfect excuse - "We're going to The Hardware Store!" And on that subject, Go watch this - You too, Gunner!

But since it's over 6 MB, the author asked me not to send everyone straight there. If you desire, you can find. * * * * Okay. Now then, back to the topic... If you don't have the proper bearing press jig or it's an odd configuration, two chunks of heavy plate or 1/2 X 6" bar stock with half-circle holes for the shaft. Go as thick as you can yet get in behind the bearing. And put some padding under the press for the armature to land on, like a pile of cardboard boxes or a trashcan full of packing peanuts - use your imagination. Sometimes they pop loose and the armature will freefall out the bottom of the press, and you don't want it bouncing off concrete (hard on the armature) or your foot (hard on your foot.) If you don't have a shop press, then I'd either make or buy a puller for the job. You can make an improvised puller for once or twice use. But if you think it will be used a lot, go buy the right puller or do some serious engineering on your homemade one - when pullers break under high stress use, at a minimum it tends to hurt as pieces go bouncing around the shop at rather high velocities. -- Bruce -- |

I favor the cut-off wheel method, cut to .030 or so from the shaft, get a
cold chisel in the groove parallel to the shaft and give it a pop. Lay some sheet metal over the shaft to keep hammer marks off it. -- Stupendous Man, Defender of Freedom, Advocate of Liberty |

I usually remove the motor rotor from the motor and put it on the
bench and use puller. Replace both bearings. They both have the same amount of hours on them. Cydrome Leader is now another candidate for the Cliff file. |
