Supercharger problem
Just had the SRT6 serviced and have been told that it has slight supercharger clutch "chatter"
Anyone know of a quick fix? can the clutch only be renewed? or does it mean a new complete supercharger?:( |
Re: Supercharger problem
Bump,
I am still having problems with this, can anyone point me in the right direction to fine out if parts for the supercharger, such as the pulley/clutch assembly, are available. |

Re: Supercharger problem
Had the rivits tightened a few months ago 4000 miles ago, it cured the problem for a while but now chattering again. Don't think it's just the pulley, sure it's the clutch.

Can you turn the clutch plate back and forth? |

The two, pulley and clutch plate, are connected by a spring and held with rivets at both ends.:confused:

Can you turn the clutch plate back and forth? The larger wheel/pulley closest to the supercharger will spin freely, then there is a gap of approx .5/1mm to what I assume is the clutch plate. this plate will not rotate at all no movement but will travel in and out if you know what I mean, this is what I think the chatter is. The chattering only happens at low rev's as the car comes to a halt, once on tick over it stops chattering. Idealy I want to replace the clutch if it is an available part, rather than repair it. without having to replace the whole supercharger. |

No one help me out with part numbers? alternative part?:confused:
Have tried google but drawn a blank:confused: |

that is because we though you knew that the only way to get a new pulley is ordering a $7,000.00 supercharger,, but you can get a aftermarket performance pulley on the forun and you might find a person that is selling a stock one,,

The gap should be even all around as it should sit on stops. |

Thanks Jim, no I didn't know but was assuming that it would be the case:( .So does a pulley come with the clutch assembly? again I am only assuming that the pulley is just a pulley!!!! and replacing just the pulley is not going to solve my problem:confused:
One of the things you might want to do is remove your pulley, inspect it, make sure the rivets are tight, then you can look at the magnetic clutch, to see if it has any damage it will have where marks on it. To remove the pulley, take the bold title the end of the pulley using either a belt wrapped or you can break the bolt loose, sometimes with everything still hooked up, once the bolt is loose( loose not remove), then remove your belt. If the pulley slides off, your good now inspect everything if the pulley does not slide off take two screwdrivers and tap,,,,, I said tap, not bang a screwdriver down a little as the pulley moves forward at one point it will get loose and come off. Don't lose the shims, count them, make sure you get the same amount going back or maybe less if the clearances to wide., If you take some real good pictures and post them, maybe myself or someone else can look at it and tell you if there's anything wrong. good luck, Jim |
Re: Supercharger problem
I have my stock pulley that I may be willing to part with. Let me know.

I asked before if this is an OEM part as some after market parts had spring problems, The gap should be as I stated before, your gap seems excessive and could lead to chatter because it is too far from the magnet and this could cause spring failure due to overstretching. You had an offer of another pulley and if the pulley springs are ruined you would be advised to take the man up on his offer. |

The price in the link posted by jmswllms is a bit silly:confused: could buy a new complete supercharger for that price (so I have been told) |

You replied to a post where someone offered you a pulley, but you said you had no trouble with the pulley. You have to read the posts thoroughly or we all are wasting time. Not exactly saying that the pulley and clutch are ONE assembley though, and when I have googled PULLEY any diagram has only shown the part that the belt runs round, so that is why I was getting confused, sorry for the confusion;) So!! if I order a stock pulley, I will get the clutch mech as well? |
Re: Supercharger problem
11 Feb, maybe this will help the pic show a pulley
the silver looking washer is not a washer it is the spring ( flat spring looks like a dog bone) there are since rivets. One holds One side of the dog bone Spring clutch and the other holds the other end of the dog bone, to the clutch there's a picture of a Shim. http://i264.photobucket.com/albums/i...g?t=1346947132http://s264.photobucket.com/albums/i...eyshow2003.jpg pic 1 you can see the spring from Rivet to rivet from clutch to pulley pic 2you can see the shims and where they go pic 3 the larger looking rivets are riveted to the spring to pulley smaller looking rivets rivet the spring to the clutch pic 4 riveting clutch to the spring pic5 you can see the rivet Holding down the spring The spring is that silver looking thing that almost looked like a washer pic 6 I took a screwdriver and lifted up the pulley to the clutch and if you look real close you can see the hiow the spring is riveted and it is a flat spring hop this clears up the pulley and clutch |

What you see in the pic in post 18 is what you will get, the silver pulley and bearing and the black clutch plate. The two are connected by three flat springs which are riveted between the two parts. The bearing is removable and hopefully you will get a good bearing with the assembly, if not the bearings cost about $50 each. You say the gap varies, it should be even more or less. The gap should be around what I stated earlier. When the springs pull the clutch plate back toward the pulley the gap between the pulley and the clutch plate should be even as the plate is pulled against stop buttons. Is this gap even? So there should be two gaps and both should be even, if the distance between the clutch plate and the magnet is too big you may get chatter as the magnet may not have the strength to pull the clutch plate so far consistently. |

Re: Supercharger problem
Thank you kind sir's:) Think we got there in the end;)
Took the car into the workshop yesterday, They are going to have a go at re-riveting the plate, with stainless rivets as the problem is being caused by worn rivets. |

Re: Supercharger problem
Ok, now sourced an after market pulley from Eurocharged Performance in Houston TX $630 + shipping.
64.7mm not the stock 73.6, claimed to add 50bhp:D will this just bolt on? or will other tunning mods be needed? I would prefer to fit a stock pulley but can't find one. |
Re: Supercharger problem
check your A F R 's at wot you should not go above 12. pulling hard in 3 gear (auto) wot if your afr are 12 or below , your good, if they are above 12.5 do not go wot until you get a tune, and intake.
some people run 12.3 to 12.4,,,, but to be safe and not blow your engine stay in the 11's,, max 11.9 stock you will see from 9,9 to 10,7 the factory makes it rich. jim |

Re: Supercharger problem
ok, when you make a change, like adding a pulley, of course you change how the factory intended the engine to perform.with the supercharger Pulley, you spend the supercharger faster condensing more air into the engine. Now you need to add fuel to balance everything out. AFR= air fuel ratio as I said before, the factory sets the air fuel ratio between 9.9 and 10.7 . That's where the black smoke comes from. Sometimes when you take off, and of course your exhaust tips are black with sutt.. By retuning the computer,to either add or take away timing and fuel and a few other things that I don't know about, they can set your AFR's in the correct range. The pulley that you ordered most likely will not increase the speed an off cause any problems. Originally I had bought a code three pulley,,62mm, installed it on my car without a tune or intake, the AFR is fine.they were reading like 11.1,, with a retune I brought My AFR's up to 11.9..
Let's say that your AFR stock are running 10.2, which is about right, you had the pulley with it being a 64 mm you probably only add 5 to 6 points with your pulley, so your AFR should be somewhere around 10 9 to 11.2 I would shoot an e-mail off to wherever you got the pulley, and tell them you do not have an AFR gauge, and you would like to know if having this pulley is going to take your AFR too high. You have to remember, the only time that this is critical is that wide open throttle ( wot) so if you want a family on and just jump on it ever so ever so often, do it and enjoy it jim GOGGLE Air Fuel Ratio |
