Well, my 626 began over heating on me on the highway the othewr day and the belts apparently fell off and i knew it was the water pump so i began the process to take the water pump out i am to the bottom timing cover and the crankshaft pulley which i have tried and tried to get off and have broken a nut off in the pulley by following what a chiltons manual told me to do....I have bent over 3 vises..i am wondering if maybe i should weld something to the pulley and try to use and impact wrench on it?will this damage anything?ANYBODY HAVE ANY IDEAS ANY AT ALL PLEASE HELP ME!!This is my only vehicle to and from work and school i walk for now as i am stuck so if you could help with some advice i would really appreciate it..I will include pictures of what exactly i am trying to pull off...THANK YOU EVERYONE!!

if you can find a partner, have them get in the car while you have a 21mm socket on a breaker bar and have them crank the engine in little bursts at a time against your breaker bar. that will get it off pretty easily. just be sure the socket is on the bolt ALL THE WAY. then, when you've got the bolt off, just wiggle the pulley back and forth and it will come off, you shouldnt need a wheel puller.

another option is for someone to hold on to the brakes while you do it when the car is in gear. but cranking against a breaker bar is much easier.

 

Similar note... I tried searching for water pump changing info for my '96 626 DOHC and maybe just didn't know what to search for, but I'm curious what process has to be followed to change the water pump. Juding by clearances, I'm guessing the engine needs to be pulled up or dropped down to allow access, is this correct? Any help appreciated. Thanks,

Brian

 

if you dont want to pull the engine, use a box wrench a lot and a LOT of patience. on the other hand Mr. 626mazdaspeed, make sure that nothing is broken (pulley mounts, make sure the pulleys are turning, etc) if something is not turning, it would result in a belt coming off, but there would have been some squealing as well...

 

I used a impact wrench to take it off, came off very easy. I would NOT use a impact for re-assembley. My car is a 97 626 2.0
