i got the mpx underdrive pulley bout a week ago, tried installing the damn thing myself but the stock pulley just dont want to come off, i rented a 3 jaw 2 ton puller from adv auto. ive spent about 50 bucks using my base hobby shop trying to get this damn pulley off, it just wont budge, now ive called shops to see how they would charge, so far ive seen from $250 to $107,
anyone installed this themselves?
thanks

 

Yup,

You need a special puller, avab from Snap-on or Mac tools.....

 

midas installed it for me for $106, there goes my streak of installing mods myself

 

U rented the puller for it and it still wont come off? weird... Ive never installed one myself, but I had intended on it and just renting the puller like you. perhaps Ill reconsider... weird...

 

TRY SOME GOOD *** PENETRATING OIL AND JUST CRANK ON THE ****. KEEP IN MIND, WHEN I INSTALLED MY UNDERDRIVE PULLEY I HAD TO CHANGE MY DRIVE BELT BECAUSE THE PULLEY WAS ALOT SMALLER THAN STOCK. IT WAS SUCH A PAIN TO TEST FIT 10 DIFFERENT BELTS BEFORE I FOUND THE RIGHT ONE! I DON'T KNOW IF THAT APPLIES TO THE MPx PULLEY.

 

i did it to my o3 se its hard but what i did is u got to take the crank bolt out but leave it in there do not screw it in just place it ther put the 3 jaw puller on it its hard get on then us an impact gun go easy it will come off and to put the new pully on u have to heat it up to 450 degreese it will slip right on be patient it took awhile
