Otc 4421 2-Jaw Pilot Bearing, Thrust Washer, And Small Bearing Pulling Attachment

Had to re turn the item as it was not straight and would of not pull the bearing correctly

this tool is comming whith a hamer hole of 5/8 why so big hole for a litle tool.

absolute junk metal. been using name brand pullers for years and this sucks. initially it looked like a decent tool but once the arm snapped it was just junk metal.

Pro: Work perfectly to remove 2001 Silverado Front Diff axle shaft small needle/roller bearing and the small needle/roller bearings on both sides of case housing using OTC 5 lb 5/8 inch - 18 thread slide hammer.Con: SPECIAL NOTE: OTC needs to step up to the plate and include a simple note within the case stating that this will mount onto two different size shafts - a 3/4 inch shaft (approx.) and a 5/8 inch - 18 thread shaft. They do not tell the user that the 5/8 inch - 18 thread threads are at the bottom of the female mount and that the initial threads in the same female mount are 3/4 inch (approx.) I was in the process of returning mine thinking that I had one that was incorrectly assembled but discovered via other's review that the 5/8 inch - 18 threads were at the bottom of the female mount.NOW, the REAL PROBLEM with this concept OTC, is that a smaller slide hammer, such as your OTC 5028 1-1/2 lb. slide hammer, will not reach down into the 5/8 inch - 18 thread section of the female mount. The solution would be to either get rid of the larger 3/4 inch threading or include two different female shaft mounts for this OTC 4421 tool. Two separate female shaft mounts might be nice but I can tell you that with my 5/8 inch - 18 thread OTC 5 lb slide hammer that this configuration is clumsy to handle with such a small set of jaws at the business end of the tool, but the 5 lb. weight gets the job done quickly. I can only conclude that a slide hammer with a larger diameter slide shaft would be monstrous for these tiny jaws. Another consideration us that the OTC 2-1/2 lb slide hammer has the same 5/8 inch - 18 thread shaft but probably would not have been enough weight to remove my roller bearings mentioned above. Also, the OTC 2-1/2 lb. slide hammer's shaft is the same length as the 5 lb. slide hammer which is 24 inches long. So, even though you can use a hammer that weighs less it might not get the job done and is still the same overall length.As far as it not fitting onto the 1-1/2 lb. slide hammer I would like to add that I can foresee other uses for this OTC 4421 tool with a very light weight slide hammer but OTC has rendered it useless at this point unless they at least offer an adapter for additional thread length to reach the bottom of the female mount.This is a great price for the tool and it is built as good as that other expensive tool company out there. I would buy this tool again without hesitation but given what I have already used it for I doubt it will break and therefore will not have to worry about this purchase. It's worth every penny I paid for it and at this point you would have to use a pry bar to get it out of my hands!

Even when working with smaller bearings where only one jaw will fit I was able to get it to work by setting the adjustment screw to help hold the jaw straight and work my way around the bearing. Even some stubborn small ones came out with less than a minute of working it side to side. I also used the 5 lb OTC 5/8-18 thread slide hammer and had no problems with the treads like some other reviews did.
