Re: 93 park avenue ulta
You are right, it should not be making that rumbling sound. A quick check to make sure it is the super charger and not the belt tension pully (located right next to the supercharger), is to back the tension off the belt so that you can slide the belt off the supercharger. Give the supercharger a spin and if you can hear it. Sometimes a tension pully can go bad and it sound like the supercharger. The second part of your question was asked by Chris NJ as "Supercharger Oil" (thread number 32 or 33). You might want to check the responce to that thread. The location the oil port is between the nose cone of the supercharger and the firewall, under some wire looms. Moving the wire looms out of the way, you should find an Allen set plug. Make sure that area is very clean before you remove the plug. Dirt or grit that might fall in the open hole could cause bearing damage. I used a Q-tip the sample the oil to see what color it was. It should be a pale yellow. Using a mirror and flashlight check the level of the oil. That should be up to the bottom of the threads. There is no drain plug so the old oil has to be sucked up through the same hole you would fill it. It has been suggested that a small turkey baster could be used. You may want to get a foot or two of tygon plastic tubing (like that for fish tanks), to extend the reach of the baster. I understand that this oil should be changed about ever year. I could not find anything in my owners manual to support that, but then I am in the process of changing out my supercharger ('92 with 120K...never changed or even looked that oil. It was pretty ugly). Back to your problem...The third part to your question is the cooling system. Coolant is supplied by the engine and comes up through the intake manifold near the throttle body. If your engine cooling system is working then the cooling to the supercharger should be working also. The next part of your question is would it run if the suppercharger were to fail. That depends on what you mean by "fail". Your Easton M-62a supercharger uses two Roots style paddles that spin to push air down the intake manifold. The tolerance is very tight . If to "fail" means one of these paddles were to come apart or fall out, the metal chips from its destruction would be sucked into the intake manifold and you damage the engine. If you mean to fail as the supercharger just stop turning as if the belt were taken off, I doubt it would even start. The only air the engine would get would be that little that might back flowed past the waste gate. The next part of your question (what is that part 6 ?) Changing the supercharger should take about 2 1/2 hours according to the flat rate manual. (I think it lied). I have about three hours into changing mine and have gotten the old one off and the surface of the intake clean but that is about it. Needless to say I will keep my day job instead. The biggest problem is the cost. A "new" one will come close to the blue book value of your car. The rebuilt one that I got ran about $600, plus shipping, plus core charge. The last part of your questionis yes, they should sound about the same at idle. However, I have noticed that the superchager Park Ave. seems to have a little louder muffler. Another thing was when mine was going bad it tended to have more of the rattling sound at idle than at speed. I don't know if any of this helped, but good luck. CrispyJo
