RRM Pulley and oil leak

anyone else have this problem?

 

that sucks man,i havent had this kind of problem yet and mines been on my car for 6 months

 

sucks dude. . . .

 

WOW...

Makes me worried about my pully.. I've had it on for 3 months now.

I wonder if this is a result of not having the harmonic dampener on it like the stock one does...

I think I may be doing a late night at work and switching pullies to investigate.

 

if you do check this out see if you can begin to see the groove that messed up his.

i've been on this thing about 7 months now. but all the times i've been under my car this past week i really couldn't tell something was wrong with the pulley. not that i was really looking for it anyways

 

No, it not having the HD is not the cause of this. Technically are cars are balanced internally with the shaft. The HD does very little if anything at all for us. If not having the HD was a big deal, you would have noticed the first time the car was started with the RRM pulley. There would have been excessive engine vibration.

RRM has sold, I'm guessing over 500 of these and this is the first one that has presented a problem. There are numerous reasons that could have caused this. It could have been RRMs pulley but its highly unlikely.

It could be Mitsus doing. Maybe they designed the the seal to last between 25000-30000 miles.

 

since when is aluminum not a metal?

 

its a weak metal?

 

from wht iv been told by my track friends that a pulley can tear up ur engine

thats kind of y i havnt bought it yet

i dono if thats true or not can any1 varify?

 

im gonna take my stock one to a machine shop and see about making a custom 1 with a metal center and an aluminum outer. Like a two piece. now Im all wierd in the head about this.

 

wow hard to believe time to take the pulley of the list

 

I also talked to a friend, he said basically the same thing. He said that Mitsu prob put in a heavy-duty seal to work with the steel pully, and that the softer aluminum wouldnt hold up over time becuase the seal will eventually wear down the shaft of the pully.

This is very concerning... I realize that RRM has sold many pullies over a number of years,without problems... but then agin, there are no long-term results with the 4b11.. being a new engine and all.

I am going to bring my stock pully into work tommorow and switch it back and take a long hard look at the RRM pully. Im a machinist and have all the tools of the trade at my disposal. I will do alot of mesuring of the shaft with variuos measuring equiptment to see if there is any wear or warping. Afterwards I look into what it will take to fabricate a steel sleeve for the outside.. Maybe I'll throw the pully on a lathe, turn down the outside of the shaft and then make a press-fit sleeve.

I'll get back to you guys tommorow with my findings (if its slow enough at work to do all this).

 

YAY for machinists who know what they are doing. I work in a production shop and most of the operators are idiots and if its not just putting a part in and hitting a button they are worthless.

 

but he made it sound like aluminum was a plastic and that the OEM pully is metal

 

maybe we should talk to rrm have them take a look at it ...maybe make a new one?
