Two Jaw Harmonic Bearing Puller and Gear Puller Universal Bearing Puller Tool or Pullers for Mechanics Heavy-Duty Pilot Bearing Removal Tool Small Bearing Puller

Seems well bilt, didn’t work for my application but feels like a nice solid puller

JAW END DIMENSIONS approximately 0.880" wide x 0.350" thickNote: The conical centering piece at the end of the threaded screw comes off if you pull it. It is retained by friction from an o-ring.This puller worked great to remove a Volvo 940 harmonic balancer (crank pulley). The jaw ends will fit through the pulley slots and the tool is short enough so you can operate it without having to remove the radiator fan and/or radiator.1) Reinsert the crank bolt, without the washer, but only thread it in about halfway.2) Take the jaw arms off the crosspiece and hook them into the crank pulley with hooks pointing to center. The jaw arms will flare outwards which will help keep the hooks engaged3) Pull off the conical centering piece from the puller's lead screw, and thread in the screw so only about 1" travel is remaining.4) Engage the puller crosspiece to the puller jaw arms.5) Unscrew crank bolt a bit if it does not contact the puller lead screw end6) Use box wrench to turn puller screw, hold on to puller arms to keep pulley from turningEt voila.

This gear/bearing puller is very durable from good quality steel. i purchased and broke two other branded bearing pullers on one job while the skankly bearing puller completed the job without breaking.

I tried 4 different pullers with failure to get steering wheel off my boat, this one was exactly what I needed. Very sturdy, doesn't bend, pulls straight 💪.Coul not be happier for $30.

Bought this to remove a bearing from a DRpro 400 wood chipper. As others have mentioned the bolts holding the arms are cheap and will strip out as soon as any pressure is applied. Swapped these out for flange bolts with washers (like schedule 8 bolts). Next challenge was keeping the arms on the bearing . Used a C Clamp for this. Next challenge keeping the arms parallel. Used a piece of hardwood cut to shaft diameter , in my case 1 1/4" , with a 5/8" hole in the middle to push the threaded shaft through up to the base of the arms . tightened the arms to this piece. Next challenge holding the assembly so I could tighten the puller shaft. Used a 4' pipe clamp at the base of the arms where the wooden spread block was. Next challenge was not Hugh shaft length to full pull the nearing off the shaft. I loosened the threaded puller shaft back and put a 1/2 " socket inside and tightened with enough added pull to get the shaft off. Gave it 3 rating because it eventually worked , It did not break , and I now know the system to have it work effectively.

I got this to help in removing battery cables and avoiding the display of red indicating fluid. It works great at being able to lift stuck terminals from the battery without damage to any of my digital extremities or the battery surroundings. I like that the jaw width is horizontally adjustable with respect to the puller so it can reach into some tight places.

Despite mixed reviews I decided to give this a try. I didn’t really want to apply heat unless absolutely necessary due to worrying about damaging something. Another reviewer recommended using a hose clamp with this which worked well. The itself I feel is well built since the gear edge kept breaking and not the tool. I will keep for future use since it has small but strong feet to fit into tight areas like on my 1.8 liter Miata. See pics. I fought to get gear off for a few days! Straddling the clamp over the gear and around this puller seemed to work best.

This thing is unable to pull the bearings off a 1/2hp electric motor with a most common NEMA #56 frame. On the shaft end of the motor the puller is too short to get under the pulley. On the switch end of the motor shaft, the the tip is too large to fit into the inside bore of the bearing, so the bearing cannot be pulled off without using a nut or something else as an additional spacer.Maybe this thing is useful for harmonic balancers, but a puller that can't handle a 1/2 hp motor is pretty useless to me. At very least they should include extensions for a longer reach. If you are thinking you can make your own extensions, the threads on the hooks are M8 x 1.25mm so good luck with that.
