Yesterday I manage to destroy one my pullers removing an engine pulley. And I did this using a 1/2 dr ratchet and not a impact; I could understand if I was using an impact. Maybe it didn't like getting hot as I had to use my torch to heat the pulley but I could still hold the section with my bare hands. I got into to see if a larger forcing screw can be installed to save it or just get a new bearing separator puller set. It is a Chinese puller so the metal is probably lousy.
I have a two arm gear puller I bought at a closing down sale for AU$12.00 15 years ago and I have only used it twice, but it worked fine removing the Victa fan blade on top the motor. The beauty is its made in Taiwan, not China. I trust tools made in Taiwan as they have a good reputation like South Korea and Japan. I am leery of Chinese made tools. I buy Taiwanese when I can, as they offer quality at a realistic price.
NormK, you must be getting obsolete stock or something, that's almost dumping them!
