This applies to all 3.0 Maximas. Keep an eye on the timing plate on the backside of the UDP, this is what happend to me.....

Out of nowhere my car was shaking and making really loud noise's. I was w/ a bunch of friends, so w/ the car running we pop my hood and there are aluminum shavings flying from my engine bay like a snow maker!!!! After turning off the car and some examining we figured out it was the UDP. The timing plate on the back was wobbly and we felt behind the the plate and noticed one of the four bolts had backed out. If your not familiar w/ the backside there are 4 bolts that hold the timing plate to the UDP and one backed out. I took my car to the shop after being unable to get the UDP myself........

The shop allowed me to watch the entire process and work w/ them, too bad I didnt have a camera. The bolt that backed out cut a 1/4" deep groove completly out of the aluminum plate protecting the block. It was not a pretty sight but not neccesarry to replace. Fortunatley I caught it in time!!! We took the faulty bolt out along w/ the other three with ease!!! What caused all this was the fact that there was only locktite on the bolt heads and not the threads. They were easy to pull out and the "removable" locktite must have been used not the "permanent" locktite......

We put the "permanent" (red) locktite on the threads and bolted the plate back on and there was still a little give to it?!? So the shop MIG welded two little dots on each side of the bolts to the plate and the sanded them down smooth. Theres no need for me to have the timing plate come off anyways unless im going to sell it to a 3.5 Max which I dont plan on. Put everything back together and it seems to be okay. The pulley still has a little more shim to it than the stock did but hopefully it will be okay.

I think the Max will be OK but I wasted alot of time and money!! I think I would have been better off spending the extra money from the start and getting the Unorthodox UDP but it was just another reminder that you get what you pay for. Im not trying to bash Motostorm but I want everyone w/ this pulley to be aware of this and all 3.0 Max's that have other brand UDP's.......

 

Wow did you see my post before yours? The same thing happened to me yesterday, what a coincidence! I talked to Brett (Motostorm) and he said the first few did have a problem with a defective timing plate. He will main you a new, improved one if you so desire, as he did to me today. I hope that solves my issue!

ok im kinda getting worried here. when did you buy your definitive udp. the first or second group deal?

 

Who said anything about Definitive?? They're talking about Motostorm...

 

I bought mine from the SECOND group deal

 

Just FYI, the red locktite is not permanent, just harder to remove. Good heads up. I'll check mine even though its unorthodox racing.

 

just a FYI motostorm is shady. brett is an a-hole to do business with. he lost my grill in the mail......i'm still dealing with him

 

I havent installed the UDP yet but I was planning on doing it soon. Is there something I can do to it to prevent the screws coming loose?

 

Last week-end I spend 7 hours installing the pulley and trying to figure out what was wrong with the Motorstorm pulley, my car was running like crap and we end up removing the pulley to find out that the little metal thing on the timing ring where hitting the crank sensor, when we remove the pulley there was only one little metal thing left on 3 tab of the timming ring. I'm really not satisfied with this product and I intend to send an e-mail to Motorstorm, i mean this is a design flaw, the timming ring should have been done in metal not alu with those little metal thing that where probably glued. The pulley itself is well machined but the timmimg ring suck *****, so now I'm stuck with that useles pulley. Honestly I'm not really interested in having that pos timming ring going back plus the fact that it hit the crank position sensor tell me only one thing they have to go back to the drawing board. Does anyone has there website link ? I need to talk with the designer and explain a thing or two.

Cheers

I tried to tell everyone about motostorm when the group deals with DMS and motostorm(both for UDPs) were going on. I tried to push everyone toward the DMS pullies but oh well

 

Just another FYI, aluminum is a metal. I knew it would be worth it to spend the extra dough on the quality product. I checked mine last night and its totally rock solid. Just a question out of curiousity. Do your pulley's woble at all? My stock one did and now the UR does also. So does Masaccio's. This is only two cars but makes me think its normal.

 

I bought the DMS. still makes me wary because the DMS ring is screwed in with screw too. I'm a little concerned. But it's a pain to take off.

 

Don't worry SamMan23. All of them use screws. I guess it just depends on what type of screw or how much they are torqued on or how much/what type Locktite is used.

 

is it a small percentage of people with probs with these pullies? ive installed 4 non UDP pullies and ALL of them had some prob or another. the worse was on a 2k that could crank a long time before starting. I verified the crank position sensor was within spec and eventually the owner got sick of it and put the stock one back in. we put the stock one back on and it started fine once again....but there must be others out there that have little or no probs

 

well, I didn't use locktite. didn't know I was supposed to. I did screw em in firmly though. Should I worry?




Were there any warning signs Trevor? such as rough idle, or bad starts?

 

btw broaner, mine has wobbled with the oem and this one. It wobbles less with this one then the oem. It used to make noises when I had the oem on there.

 

I sent an e-mail yesterday to Brett at Motorstorm explaining the problem and design flaw, but no answer so far.

Be patient, Brett is normally online late at night. He's a good guy, he does his best to provide the Maxima community with parts.

I recieved my new timing plate today. It is made out of thick steel, as opposed to the aluminium ring I have on there now. It will be replaced Monday and hopefully all will be well.

Like you said Brett has alway been nice so was my e-mail.

I'm shure he'll get back to me soon.

Cheers

Hey guys, Brett just sent me an e-mail and he will rush me a new metal timming ring asap, so hopefully I should re-install the pulley this week and see how it work.

Cheers

I'm throwing a code for timing, and I'm willing to bet its cause I'm missing a few tabs from my aluminum ring as well. I'll be checking tonight and emailing Brett if thats the case.

[QUOTE=SamMan23]well, I didn't use locktite. didn't know I was supposed to. I did screw em in firmly though. Should I worry?


I talked to Nick at DMS about the screws backing out on his pulleys and he recommended using superglue instead of locktite so I guess that's what I'll be using.I don't plan on using this pulley on any other maxima so I'll never need to take the ring off anyway.

 

I had the new timing ring installed today. Car started and ran perfectly. Upon examination of the old timing ring, it appears the steel covers over the aluminium tabs had flaked off on two of them. This would undoubtably account for a timing problem as the crankshaft position sensor cannot detect aluminium. Well after all the car runs fine and it turns out there are some parts you just can't lose weight with!

Yep. He's mailing my new ring off tomorrow I hope. Should be here by the end of the week along with my new knock sensor. I'll be thinking I'm driving a new car. Can't wait. Thanks for the heads up man.

 

Brett is sending me the new timming ring, this was the weak link to this nice pulley can wait to install.

Cheers

so this problem is at this point only with the Motostorm?

 

So far, I believe so.

How does the timing ring work? I figured there would be some sort of internal timing thing on such a modern engine but... Is that little sensor behind the crank pulley a electro-magnet or what? Just curious. Mine often collects little bits of dirt or steel wool pieces from all the polishing I've been doing. I guess I should clean it off more regularly.

 

Im planning on putting the pulley on sometime soon because I need to change my belts. Is there something else I can use besides red locktite that is more permanent to hold the scews in? I was thinking something like JB Weld or some epoxy?

 

weld it, not worth taking the chances. the only downside is if you choose to sell it later you can only sell it to 3.0 max's, and not 3.5s
