Okay, so I am finally going to replace the water pump and timing belt on my new (new to me) motor. I got the crank pulley off with not too much sweat and tears from my old motor to get my brand new water pump out of it. However I cant for the life of me get the crank pulley to move on my new motor. I have been hammering on it for about 20 to 25 minutes with the impact and it hasent budged. I have busted the head off one of the bolts of the puller and have almost broke the socket a couple of times. My impact is getting to hot to use at times also.

Does anyone have any tricks? or know of any way to get some kind of penetrating oil under the the pullet to get it loose? I have tapped it (not hard so I didnt kill any bearings I hope) with a hammer and nothing. Im gonna go nuts soon. All I have is a propane torch so that isnt gonna do crap all to heat it up...

Thanks,

Mike

 

What Size air compressor are you using?

A professional quality Air Impact Driver with a good Heavy Duty Air Compressor will put the pulley back on!

I have tried Electric Impact Drivers and Cheap Harbor Freight Air Impact Drivers with NO success until I bought a quality Air Impact Driver 1/2"

its an electric impact driver. Its got lots of torque, but not enough obviously. Im just in my own garage, my compressor probably can't blow out a candle let alone run an impact gun.

That sucker is on there good...

 

update

i have now broken 2 gear pullers....

 

ywhat kinda puller are you using???...i have a snap-on puller that is only about 3 inches tall and uses push rods to push off of....it wirks great...but autozone rents the same type of puller but i believe its an OTC...but either way just the same and works just as well...and im pretty sure you wont be breaking one of them.....and when you get alot of tension on the puller, lightly tap the push bolt dead on the head a few times....that works alot of the time

 

I have been using 4" jaw type pullers. Im gonna call around to see if I can rent something with a little more *****.

 

you could even buy one, but its more then renting one...my snap-on was like 120.00 but i think that OTC is under 60.00....i once tried to get off the crank pulley using a cheap puller from J.C. whittney....ended up goin there and buying about 3 a day....i think i went through about a dozen of them, then i got the snap-on, never failed me yet

 

Make sure the insert you are using is long enough. That is why most pullers get broken. If you can't find one, use the passenger size motor mount bolt as the insert...some say this is a bad idea, but it works.

 

before i got my snap on, i took a 3/8 drive long extension for my ratchet and ground it down so that it would fit into the hole...it worked, until the last time that i used it...it got stuck in the hole...but i t didnt matter because i was junking the car anyways

 

okay im sick of snapping these things.

Would it be a real bad idea if I just cut off the pulleys and then ground it down so its just a thin layer over the crank and broke it off? I have a spare crank pulley that I could use.
