Purchased a KJR Pulley from the board member.
Took it to my mechanic and he told me that it has a 1mil. deep groove from being previously installed.

He told me that it will leak oil from the engine and advised me not to install it.

Anybody had problems with these?

Thank you.

 

well from what i can see you have a 1mil deep groove on it, and its from being installed before. Im reckon you not to install that there pulley onto your that there z.
talk to the kid who sold it to you!

 

Mechanic seem to know what he was talking about.
I`ll ask the seller

 

Hmm, looks like the CNR pulley isn't the only one with this problem... See this thread:
https://my350z.com/forum/engine-and-drivetrain/191612-problem-with-cnr-pulley.html

Get a UR pulley. They have a steel sleeve that prevents the seal from wearing grooves in the aluminum.

 

thats what the mechanic told me.

The guy that sold me the pulley never mentioned any problems with the pulley.

I hate dealing with this now.

 

my kjr is fine.

 

mechanic said that engine will leak oil if i install the pulley with that groove in it.

 

It may leak, it may not (right away, but prob will eventually). One of the CNR pulley guys in that thread had major leakage, I have only a very minor drip and the guy that posted pics of his pulley with the grooves in it had no leakage yet. Bottom line is: don't risk it; go UR or stay stock.

 

Well i purchased it from a forum member who said nothing about it.
Wonder if he will take it back.
I dont want any oil leaking thats for sure.

 

One thing interesting about this forum. You will get yes answers...

and no answers. Take your pick.

 

 

Give us his username if he doesnt give you your money back, that way no one will buy off him

 

Give him a chance to do the right thing before you smear his name all over the place. You would want someone to give you the same oppurtunity. My 2 cents.

 

This problem of the seals wearing grooves in balancers isn't new. It was so
common in small block chevies, Fel-pro sold a steel repair sleeve that you would
coat with locktite and tap on with a rubber mallet. ALSO! The chevy
balancer was cast Iron. I have a KJR that I will have a steel sleeve installed
on before I install It. I miked the diameter, it is 48 millimeters. Has anyone
measured the size if the factory VQ pulley? If the factory size is say 50mm
and the aftermarket size is smaller that may be the cause of the pulley leaks.

 

That is why i am asking questions around before acusing him of anything.

 

Where did you get the steel sleeve?

 

Okay..sorry. It seemed as I was ready the responses, that the crowd was getting ugly and a lynch party was forming. Good thinking.

 

I bought it at the local auto parts store.(for my chevy) Take yours to a major
auto parts store like Napa. The sleeve was razor blade thin but FEL-Pro provided a new seal.
I think everybody is slapping on these pullies and not replacing the seal which you may be able
to get away with if the aftermarket pully is close to the same size or larger.

 

not sure i wanna experiment...

I rather get my money back
