^he said to email him.

and if anyone comes across the link to teh part number for the steel sleeve for the KJR, i'd appreciate it.

 

FYI - UR makes a pulley that is OE diameter for the s/c guys.

 

hmm yeah it is listed on their site:

Sorry for the late chime in here guys, i just was reading up on some posts, came accross this, and wanted to let you know that even I have just found an oil seal issue on my Z....
I have the KJR too, but was running it for oh...nearly 2.5 years. I don't know if the leak has been going on for a while or not, but it's pretty bad now. So simple fix early next week will solve it. Just wanted to chime in that it can happen to anyone

 

What is the simple fix? A steel sleeve? Any info appreciated.

 

Yeah Tony, what's the fix, the '99189 speedi-sleeve' from Baum Hydraulics?

Or for people who just want to get a full replacement, will this work?

We've had many problems w/ the KJR pulleys, we just replace them w/ UR pulleys and a new crank seal... Result = Best Quality Pulley, No Leaks, No problems, Proven HP Gains, and UR Warranty. Enjoy

Here's the seal, and the pulleys to fix the KJR issue. You can also go back to the stock pulley w/ a new seal to fix the issue.

simple fix AS IN swapping out the oil seal, etc... and removing the pulley, sorry I did not mean to elude to any other probable fixes for the issue, i just meant that it's a reletively simple thing to fix in general, considering I was expecting worse news with regards to oil loss lol

 

Just ordered my new stock sized pulleys & crank seal from Coz. I have a 300HP/Rev-up engine, so I hope these will work.

Thanks Coz!

 

I was one of those people that also had an issue...

Remember this pulley is designed by a kid... he's still in college. Not a engineer.

Thats why I say SCREW this product! It ate my crank and others have had this same issue!! BECAREFUL!!! DO NOT TRUST KJR PRODUCTS!

 

its funny they havent posted on here in a long time...ive had mine on for about 40k miles with no issues so far and i replaced my belts like 20k miles ago and didnt see any problems then either...regardless to say my next belt change i am installing a set of agency power pulleys i received as a gift

 

Well, I have Pm'd KJR to no avail... No reply. Oh well, it's all over now, car's fixed.
here are some pics of the KJR pulley when it came off, you can see there are two areas where it was being cut into...

 

So Tony, did you end up swapping the pulley for the Unorthodox Racing one? Or just added the steel sleeve?

 

Tony's pulley looks EXACTLY like how mine did when I pulled it out.
I say go with UR and never worry about it again. That's what I'm doing.

 

Yeap, that's exactly what I'm doing too. As a matter of fact, I just received my UR pulleys.

 

UR squeaks.

buy a 20 dollar speedi sleeve and put it on the KJR, that is basically what the difference between the UR and KJR is.

 

A what?

 

I didn't bother going with a new pulley, so i just put the OE one back on. 1) i need the car back quickly, 2) now that I drive with the OE on there, it's not a real noticeable difference in my car with the blower n e ways....

I'm happy that the OE will not have the issue.

But I'll keep trying to contact KJR for everyone on here too...

 

again... DO NOT BUY KJR PRODUCTS!!! THEY ARE MADE BY A COLLEGE STUDENT WITH NO FUTURE OR INTELLIGENCE WITH ENGINEERING!... Hell he hasn't had a working Z for about two years. He cares less about customers or anything you might need help with...

Horrible company and 0 customer service!
