This Stock Pulley Has Been Turned Down To 66.8mm If You Look Closely At The Inside Of Pulley You Can See A Groove That Prevents Going To 65mm Which Would Be Equal To C3. I Can Not Figure Reason For Groove But It Would Make The Pulley Way To Thin. There Is Only A 2.7% Difference. If You Would Like To Have Yours Done Pm Me

i Have One Extra Pulley That I Can Do A Swap I Want To Evaluate Yours First
personally I Would Rather Have A C3 But This Is As Good As It Gets For Now.

 

thats a great undertaking!! maybe post it on the srt-6 section. they may be very interested

 

Fill that groove with a nice weld, grind it smooth, then machine it to the max. Nice work; I applaud your efforts. I would have jumped on this a couple weeks ago.

 

That's what I like to see, someone using a little initiative, take the OEM part which is well made and better than the C3 and adapt it. Well done.
The groove is probably the division point between two different diameters, one a bearing fit and the other a shaft fit, with metric standard sizes and tolerances for both.
Edit
Just seen the last post, do not weld it as I am sure you know. That could ruin it really well.
Precision parts are not welded unless every think is welded and totally re machined. The welding would be done with a laser and very carefully, no bloody great spark and heat.

 

pm sent....

 

I thought TVT or someone was able to machine theirs down further. Not sure if they got anyone to bite on their deal, so no proof. Good job for getting it done.

 

care to expand on why you think the oem is better than the c3?

 

Because of all the trouble with the first ones, loose rivets and I believe odd sizes and shimming problems. I'll do a search sometime.
I am sure the OEM ones are better made and more consistent. But what do I know, that's just what I remember.
I have never had one in my hand.
The envelope to make a new one is the same as modifying the old one, so no benefit from any additional strength. Depending on how close the grooves are to relief in the bore there should be no problems.
Modifying the OEM seems to be the best option and has the benefit of economy.

 

the only real trouble with the original c3 pulley was the grooves that were cut into the pulley had sharp edges that ended up cutting the belts. as the pulleys wore in the issue disappeared. this issue was also eliminated by not having the grooves in genii 2 pulleys.
the loose rivets were a problem with both c3 and oem alike. as the pulley engages and disengages the spring steel and the rivets become worn. every single s/c pulley will eventually succumb to this wear. there was a member on here that was repairing his with aircraft grade material but never saw any more after his initial thread.

to never have held one in your hand and say the oem is better is a bold statement. i have both and have held them both in my hand. both are very good quality and serve the same purpose. to machine the oem down is a great way to inc. boost for an inexpensive upgrade. if its done properly.
i think the op did a great job but until it is smaller than the c3 or at least equal it will still be inferior to the c3. just my .02

 

I'm full of Bold Statements. Some say it's just simply BS.
There were photos of the originals and they were not too good to look at.
I would imagine that anyone who has an original C3 and thought it was worth its weight in gold is now re thinking its value.

 

are you still offering these?
I have sent messages with no reply....

 

Nice job! I was lucky enough to have one of the original C3 pulleys without any problems.

 

I Talked To Tvt When They Were In Business And I Am Not Sure They Were Aware Of Internal Grove. It Is Filled With Plastic And May Have Been Missed.

 

still waiting to hear back from you....
sent pm's...

 

why would you reply to this thread, and NOT reply to people who aare TRYING to buy your product??
does not make any sense....
Please ignore my request to purchase your product.

 

Rick,
You Have Heard From Us And I Hope Everthing Is Under Control.
As Soon As Your Pulley Arrives I Will Return The Reworked Unit.
Please Let Us Know What You Think About The Quality Of Workmanship

 

so are you a member or a business? are you doing the work personally or farming it out to a machine shop?

 

No problem.
I can email you the tracking number for the pulley I sent you.

Rick

 

They had it sent out to a machine shop in California

 

not A Business. Just Interested In Providing A Service To Fellow Members.
However This Has Gotten To Be Such A Hassle I Do Not Think I Will Do It Any More.
