guys i took off my superchargers pulley the other day and wow thats all imam say, well here we go i dont got a pic of the stock pulley but that thing is finished, its done, i got the new pulley on but wow, the pulley puller coudlnt get the pulley off instead bent it, and then we heated the hell outta it and put 15 tons of pressure on it and it snapped something and then came down, and then getting the new hub one was horrible, the thing was so tight we tryed pressing it on with the pulley puller but didnt work we heated it till it was glowing and put it on and abnged it on but wow is all imma say, how did u all get yours on and off so easy?

oo let me add i will deff have pics tomorrow to show u the new pulley and the stock pulley

going to bed, but let me know guys and tomorrow ill have pictures up

 

Ohh I didnt even have a pulley puller when i did mine. I had a funny day with my pulley swap let me tell you.

 

Hopefully heating it up that hot didnt liquify the grease in the bearing in the snout.
When you got the old pulley off did you make sure that the shaft was smooth and free of burrs,also a little lube would of went a long way in helping it back on.(Nothing worse than trying to put in dry, takes alot more effort)
The bearings in the snout Im sure are not meant to take any linear force on them ,make sure you listen to it so that you dont get any bearing noise in a short time.

 

heating up a press fit wont do anything when both members have the same coefficient of thermal expansion

i.e. steel shaft and steel pulley. They both expand at the same rate.

If it was an aluminum pulley and steel shaft.. then yes that works.


Most of the time, Heating one member and cooling the other applies during assembley.. not dissassembly because you can choose which part gets larger and which gets smaller. After they are together, heating and cooling doesnt really work very easily.

I would definately NOT reccomend heating the supercharger to get the parts on or off, the press fits are NOT that tight. and Also, if you pressed the pulley on or off without pushing against the shaft itself then you did damage your bearings.

 

you may have jacked up your s/c man. mine came off with ease, i used a gear puller rented from pep boys.

 

dam guys, nah i didnt really heat up the shaft when taking it off, i just heat the pulley on the inside and we couldnt get it off wat so ever, here let me go take pics to show you my stock pulley and wat the pulley puller did to it

 

i guess i was lucky.. my stock pully still looks brand new..

 

ok here are the pics, i got views of top and bottom and then the sides on both, oo btw yeah thats my 2.8 chilling on the side and then a pic of the stock size on the blower till i get everything else

 

Wow man you focked that shiot up

 

haha nah man the pulley did, and well i had a trained mechanic pretty much do it, and he didnt know why it was on so bad and then he called snapon about it and then they didnt know either, but its fine i got my new pulley on so the car still runs
