Still no response from the seller.

 

And how exactly does one just run out so easily and get this sleeve that just so happens to be the perfect size to fit a Nissan VQ aftermarket crank pulley, let alone getting the pulley itself machined down to accept the sleeve so it still fits the crank? Jeez, just get a UR pulley.

Question, though: will the seal itself need replaced after this occurs, or will just putting in a sleeved pulley do the job?

 

So what's to gaurantee that the pulley will still fit with a sleeve on it without being machined down first? The sleeve will increase the diameter of the pulley shaft. Sure, not by much, but we're dealing with parts that have tight tolerances here; you wouldn't expect to be able to slap a sleeve on the stock pulley and still get it to slide in the hole, so why would you be able to with an aftermarket pulley that has the same diameter shaft as stock? Those things are a pretty damn tight fit as-is.

And what is Brg. House???

 

I'm not doubting your experience or knowledge; just asking for clarification. I did not know the seal the pulley shaft slides into would allow for slight diameter variations of the pulley itself. That's good to know. Of the several pulley installs I have done, it seemed as though the pulley was sliding into a very tight metal hole before going through the seal that didn't feel like there was any room for added diameter, but I could very well be mistaken as I'm not intamate with the mechanics of how the whole thing works, exactly.

Hopefully someone will research this further and find a suitable sleeve that will solve the problem, as both the KJR and CNR pullies are succeptable. I already bought a sleeved UR pulley to replace my CNR, so I'll just stick with that (I'll probably go ahead and replace my seal while I'm at it). If someone finds a suitable sleeve, though, be sure to post up the specs; alot of people will benefit (and I can sleeve and resell my CNR at that point...).

 

Cool. Can't say I've ever seen a bearing supply place at he local strip center, but I've never really looked; have to hunt around and see if there is one nearby...

As I currently have on a CNR pulley with slight leakage, I can only assume that I have thr grooves in it as well (there is a thread pertaining to this in the Engine section of the forum), so my seal likely needs replaced. I've learned from another member that is is a cheap part and fairly easy affair to replace it, though.

 

The miked diameter of my aftermarket pulley is 1.89 inches. so I went to an advanced auto with my new pulley and a copy of the picture from this thread of the grooved pulley. The sleeve the counterman found was The Sleeve and seal from FEL-PRO part #16213 this sleeve requires a 1.875 in Diameter shaft and it is also .920 in long. The length of the sleeve needs to
be .710 to .720 inches to bottom out on the shaft and clear the fillet.
The outside diameter of the sleeve is 1.90 inches. There may be a closer size
but I wanted something in stock so I can repair it at my monday night machine shop class. (The instructor won't let me f**k it up)!

 

I forgot to add the price $7.31 + 6% sales tax!

 

Thats alot of info for me to process.
Dont really want to deal with all these issues.
The seller should have told me about the problem.
Still cant get in touch with him.

 

I'd ditch the pulley, move on with my life, live and learn. Hope you did not waste too much money on this.

Sucks, but if it's around $100-150 which I'm guessing is what you paid, then it's not THAT bad of a loss. You're much worse off if you install it, have problems, have to uninstall it, etc etc etc

 

So does all this mean there is not a sleeve available that is the right size without machining something?

 

Wow, somebody wake up on the wrong side of the bed? I wasn't asking you, anyway. The info. posted above is spelled out with all the clarity of mud, so I asked for clarification. You said that with the proper sleeve, no machining will be neccessary. So what is this guy doing in his machine shop class? The sleeve he found does not look at all like a perfect press-fit out of the package from the measurements he gave.

I may be the only one asking these types of questiuons, but believe me, I'm not the only one interested in the answers. Personally, I couldn't care less; I already got a replacement pulley from a UR that comes sleeved from the factory; I'm just trying to keep this going with the clearest and most detailed info. possible for all others out there that have this problem (which I share with the members of the Infiniti FX forum I moderate, many of which have succeptable CNR pullies).

I am an excellent problem solver, thank you very much; the purpose of forums such as this, though, is to pool information and draw from one another, which is especially useful when discussing areas outside of one's own expertise. Most people here don't have 2 engineering degrees, nor built machines for forty years, so what may seem perfectly clear to you may not be to alot of people. If you don't want to continue to contribute, that's your perogative, but there's no reason to get all snooty about it.

 

LOL

Ok, so when you say press fit, how exactly is the sleeve installed on the pulley? Is special equipement needed or is this something that can be done at home without screwing up the sleeve? Being as thin as they are, I assume they are fairly delicate until firmly in place.

 

Cool; good to know it can be DIY. Just a matter of finding the right sleeve, then...

 

As for my machining I did NOT install the repair sleeve because I could not get the pulley centered with less than .0025 inches of runout. The high school abused lathes have slop in then as well. I needed a thou.or less to feel comfortable with the end result. I will try to find a sleeve that is a closer fit, to eliminate the need to machine the shaft.

 

Given that the pulley isn't going to gain you any noticeable whp, why would you even consider installing it?

 

Now I am not sure if I will

 

Be careful with any lightweight pulley.... This is what happened to mine and I will NOT be installing any other type of lightweight crank pulley aver again for the miniscule amount it produces.... Definately not worth the risks... This chewed up my crank shaft and 3K+ later I was on the road again...

 

who is the manufacturer for that pulley?

 

Thanks E***zzzzy for being so helpful. The hub shaft diameter is 1.890 In.
the depth to radius is 0.690 inches.

 

Hmmm
