I am in desperate need of borrowing/renting one of these gear pullers. I cant afford to purchase this tool for the 2 times I will use it. I have tried 3 jaw puller. 2 jaw puller, modified 2 and 3 jaw pullers, heat a d a little hammering(carefully because the crank bearing uses a plastic ball retainer in the bearing. I understand this will take a bit of trust in me but I assure you you will receive your tool back unharmed.
