No, there should be no play in the shaft if you move it back n forth. Usually that is a sign that the coupler went bad inside of the supercharger.
Could be the bearings/pulley. until you fix the issue you should remove the charger belt, so it doesn't get worse (blow the supercharger).
Pontiac or any local GM dealer should be your first phone call. As I recall they are filled at the factory and the fluid does not need to be replaced.
Yes, I would highly recommend it. The supercharger uses a speical oil called, "Supercharger Oil." You can get this oil from GM, however it does cost around $8-$12 a bottle. The oil should be check every 3000 miles and changed out once it smells bad or looks dirty.
You don't have to replace the supercharger you will just have no performence power and bad gas milage, but you will not harm the supercharger. Same thing happen to me, year later I replaced my supercharger belt and supercharger was fine.....dont wait get it fixed dont hurt the GTP!!!!!
Any supercharger should only be installed by a competent mechanic to avoid destroying your engine.
I have been running this engine in my car for 3 years now, makes the Fiero what it should have been. Scary fast and completly reliable if done right. There are several good references on the web to tell you how and sell you the parts.
the coupler is probably worn out. replace it and the oil and it should be fine. if not then the bearing are bad but most of the time its just the coupler. http://www.zzperformance.com/grand_prix/products1.php?id=155&catid=106
Usually you should plan on changing your supercharger oil once a year or every 20-30,000 miles. And yes it can be harmful to the supercharger to not change the oil in it, just as not changing the oil in the engine would be not to change it. Folks the oil cooling the superchargers I am aware of is the same oil from the same reservoir as in the engine. So when you change oil in the engine you are changing oil in the Supercharger as well. If this is not the case, someone please tell me as well. The oil in the supercharger is not the same as engine oil. Do not use regular engine oil in the supercharger on the GTP, it requires special oil. It is not connected to the same resevoir, it is totally separate. The last comment informing that the Supercharger oil is entirely different and not connected to the engine oil completely correct. Regarding charing the supercharger oil, the owner's manual states the following: "Unless you are technically qualified and have the proper tools, you should let your dealer or a qualified service center perform this maintanence." The owners manual then goes on to state that the oil in the supercharger should be every 30,000 miles or 36 months - whichever is sooner. To check your oil on the supercharger, do the following: 1. Make sure your engine is cold - i.e. at least 2-3 hrs after running. 2. Clean the area around the fill plug on the supercharger so no debris or impurities get in the system. 3. Remove the oil fill plug w/ a 3/16" allen/hex wrench. 4. The oil level is correct when it just reaches the bottom threads on the inspection hole. 5. Repleace the oil plug w/ the O-ring in place. 6. Torque to 88lb-in. The type of oil for the supercharger is Supercharger Oil GM Part No. 12345982. -gz1
If the belt only drives the supercharger, you should still be able to run it, but expect a drop in performance. Have it repaired as soon as possible
Yes I have one in my 96 camaro and it is awesome!
Maintenence on a supercharger is to check the oil level every 30,000 miles or 36 months. CAUTION:do not remove the oil plug when engine is warm.Removing the oil plug at warm engine temperatures can cause hot oil to overflow.this could result in oil lossand possible personal injury. Notice: the oil level should be maintained to the bottom of the plug threads.Do NOT use petroleum based oil.When adding oil use GM part #12345982 synthetic oil.Failure to do so may cause supercharger failure. Remove the wiring harness shield to access the oil plug. Doc J
Typically, no. Assuming a bearing failure or similar problem with the supercharger, you should just be able to replace it and be done. If however, there was a catastrophic failure of the supercharger, pieces of metal and debris could have been sucked into the engine and may have caused damage. You should be able to determine whether debris is present based on observation of the supercharger once it's removed and by inspecting the intake manifold just underneath.
