I found out after the fact that my pulley I had installed is an adjustable ASP pulley. Have heard bad things about that RTR pulleys. This is a similar design but doesn't appear to be aluminum like the RTR. Should I be concerned about this ?

who did you purchase it from and who did the install? you should have seen the pulley before it was installed to verify what you were getting.

Was from a board member. It was brand new not installed. Had a Master MB tech who is seriously into modding these cars install it. He did say it had no aluminum like the ones that seem to have so many issues. Hoping it is ok. He wants to check the bolts and such pretty soon to make sure it is ok. Heck he even offered to install a new pulley free of charge. I had asked him about adjustable pulleys in the past so he thought I wanted this when he got the parts. I didnt know enough to realize I had one of those. I just new it was an ASP one which were supposed to be good.

If he's an expert like you say he is, I wouldn't drive the car hard at all until he checks it out. 'C' mode only, no romping.

Do you have a pic before it was installed so we can help ID it?

ArmoE55

^ Great idea.

Post a few pics.

Def get a new. Pulley to replace it

dllhg

Sorry no pic. He did confirm it was in fact an ASP pulley which is how it was advertised to me in the classified section here. He said it wasnt aluminum like those other ones that have a bad rep.

As for not romping on it, well I have been romping the hell out of it Been hard not to. The car is so damn much fun now. Was planning on a remote dyno tune this week and a track day next Sat.

Too difficult to take a pic? People here are trying to help you to identify what pulley you have and whether it's safe to run. If you trust the seller then why bother to ask? Oh we'll, good luck!

Romping on a pulley that you have doubts on and without a tune?

dllhg

I was trying to find info on this ASP pulley. Does anyone have any info on this version of ASP pulley ? I know a different branded adjustable pulley has issue but that doesn't mean the ASP one does. Was looking for info on this particular pulley. I also clearly stated it was not only sold to me as an ASP pulley but the installer also noted it was an ASP pulley. It just happens to be one of their adjustable ones. If you dont have any info why bother posting ? I think I made that pretty clear from the start.

FYI I clearly have a tune. It is an OE custom tune.... like the sig shows. Was talking about getting a dyno tune since the present tune is conservative . They wont put an aggressive tune on it without having some dynos and AFRs. Probably a lot of power left on the table.

Are you sure this isn't an ASP bolt style pulley versus an ASP welded style?

He may have the bolt style pulley that was (correct me if I'm wrong) made by ASP but designed be EC.

Pretty sure you are dead on. He is saying "adjustable" because it is the 2 part pulley that the whole pulley part bolts to the back portion (harmonic balancer part) vs the welded ring pulley that ASP takes an oem harmonic balancer and welds a ring to it instead of making a complete pulley from scratch harmonic balancer and all (the pulley he most likely has).

Which is also the pulley I had fall off my car (180mm version) and a few other members also had fall off their cars. And they were on there for several thousand miles also before they fell off. Poor harmonics of the built from scratch design most likely the cause.

This pulley that has caused some problems on top of the "RTR" Red Tooth Racing pulley that had the aluminum color ring bolted on that caused major problems real quick for many members.

I had a VRP 180 bolt style that the rubber on the balancer went out on after tons of miles. Installed the bolt style ASP 180 and then it fell off. Now I have the welded 195 ASP pinned and no problem for the last 3k miles and making the power listed in my sig.

I would say welded is my pref but the VRP bolt style did last a long time. I still haven my ASP 180 bolt style just sitting in the garage.

dllhg

Sounds like that is the one I have. I'll have the installer look at those pics and see what he says. I am surprised ASP and or EC would sell/make a substandard part like this. I didnt know enough at the time to ask the guy if it was a welded ASP pulley or not. I assumed it was.

So it sounds like I should go buy a new pulley ..... Maybe I should look into a 190mm .... My IC water temps are down to about 42 degrees keeping the IATs good. Probably shouldn't push it. Just hate having to buy something I already bought damn it.

Not to call anyone out but there are people who have ran the RTR ones without issue and it seems that most of the pulleys falling off it due to improper install since most people do not understand that it is a torque to yield bolt that under no circumstances should be reused since they stretch. Also since it is a torque to yield bolt people tend to just go to torque spec and forget the additional 90° turn that is required.

dllhg

It did come with a new main bolt. I will ask him about whether he did an extra 90 in it or not. What happens when one "comes off " anyway ? would it be possible to pin the crank on this pulley ? I know people did that a lot on the GTO blowers for safety.

SPatykAMG

Being that he is a Mercedes tech he should know about the 90° but when the pulley come off it does damage to the guide on the crank which holds the pulley to spin. Although I have heard of a member who dremeled his to repair it after this had happen.

As far a pin the crank I am unsure if this has been done

urbamworm

Sheering the woodruff key is what happens when the bolt loosens and the pulley comes off then some had some nasty banged up cranks too (RTR pulley guys). Some people have added a pin on top of having the woodruff but in reality does that even do anything? The bolt torqued down is what holds the pulley in place from spinning, not the tiny woodruff key. It is there for alignment purposes and is very small (short out of the crank in to a groove in the pulley) and short lengthwise also (like 1/4" long). Mine has been drilled and a pin added after the key sheered to retain the correct alignment but it really doesn't even matter unless the engine was taken apart. It would be used for timing purposes so the pulley is correctly aligned with the correct position of the stroke of the engine so the degree marks on the pulley can be used.

As for people doing it wrong or right, well there have been many that were installed by shops that frequently work on Mercedes or like myself and another member strictly on Mercedes so you would think the improper install would be ruled out. Like I said, mine and another members were also on for a long time (mine like 10,000+ mile) where some others had problems with theirs falling off almost right away (I am talking RTR pulley and the ASP bolt style we are talking about in here).

dllhg

The idea of even the ASP pulley falling off makes me uneasy. I hate that I just spent $800 on this pulley only to find out it is a hazzard. ASP or EC should offer free replacements on items like this in my opinion. Should be just like a recall. Maybe I will try and contact them and see what they say. My tech offered to replace the pulley for free if I had a new one.

I never trust mechanics, theyre all shady people and all about making profit, bet he was gonna get ur good adj asp pulleys and put some stock crap that he has used in store

Hulk

Dllhg, many here told you to buy brand new for the pulley including myself, you even went as far as to say some things about a good guy on here which were not true and now you are scared of what you put in your car?

Off the soapbox..welded is always best

dllhg

Please reread, it is a brand new pulley. It was never installed. Why you are bringing up something I said about someone else doesnt really make sense . The fact is what I said was 100% true and posted a quote from that email between us Can we now get back to reality please ?

Hulk

Maybe I'm mistaken but didn't you buy a used pulley off the classifieds? If I'm mistaken then I take it back however alot of us said go with the welded version
