c3 question
c3 question
ok im having problems getting my c3 pulley on. i hope jake or someone with a c3 can answer this question.
i have 3 oem shims and 2 shims provided by jake with the c3. the total thickness of the 5 shims are 1.60 mm the depth of the oem pulley is 25.02 and the depth of the c3 is 25.82 mm respectfulley . that is a difference of .80 mm just to get the c3 level were the oem was. then add .20mm to .30 mm as instructed in the c3 directions im looking at a total of .100mm to .110 mm to space it properly!
with the 5 shims i already have i need to add another .60 mm to .70 mm to c get this right. thats approx 7 to 10 shims! that sounds excessive to me. what am i doing wrong?
the first foto is oem pulley and 2nd foto is c3 measuered from the inside shoulder to the top

Something is not correct if you already used that many. Good luck as I don't know what else it could be.
Re: c3 question
I have the last generation aluminum Code 3. It used no shims at all. If I remember correctly the installed clearance on the stock pulley was 45 mm to the clutch. My Code 3 had varying clearance when new. 25 mm at the tightest point and 47 mm at the widest. I was told it would wear itself flat. I measured from the bearing like you but can't remember exactly what I found but it was not even from one side to another. Sorry quality control. But the sucker works flawlessly and I love it. Don't try to make the numbers match. They wont. Put it on, measure the clearance to the clutch for posterity, watch for signs of the belt slipping (mine doesn't) and fry the tires. Since you have shims, I'm pretty sure 20 mm is the recommended clearance between the pulley and clutch in the install instructions from Code 3. You might check the website to be sure.

i really dont want a crank pulley. i avoided using c3 for a new pulley due to so many negative posts by members. getting it from a reputable shop used seemed like the best of both worlds. not so sure now. and to top it off my oem shows definate signs of wear from the bearing so putting it back isnt gonna happen.
the c3 instructions also call for .20 to .30 mm clearance i believe most confuse this with 20 to 30 mm major difference
Re: c3 question
OOhh. Did you tap it with a brass hammer? It sounds like it's not seated properly. (well I hope thats all it is.) The grooved Code 3 is the original version. I can't imagine it needing so many shims unless you somehow got the worst Code 3 pulley on the planet. Mine was a huge disappointment with the dial caliper and feeler gauge, but works great. Good luck getting to the bottom of the problem.

I had to use a total of .80 mm of shims and had no problems for the few hundred miles I used it till I went 181mm.

hopefully brandon will answer his fone tommorrow
Re: c3 question
just a quick update for jake and anyone else interested. i finally got in contact with brandon and found out the spacers for the pulley are rear differential spacers. so i went to a couple shops to get some shims and had no luck! most shims were 29 mm id and the s/c shaft needs 32 mm id. so brandon sent me 2 shims and a new bearing for my oem to keep as a spare.
short story long my pulley is on!!! i needed 1.1 mm worth of shims to get .40mm clearance from the clutch. i would like a little closer spacing but any closer touches. needless to say im super impressed! ive burned the tires launching now sideways thru 2 gears! torque monster is an understatement.
thanx to all who gave great advice. thanx to jake for cutting me a great deal and putting me in a new mod level!. lets go to the dragway in oct!
