I figured out a way to change the oil on my 1st gen supercharger without losing any oil on the motor.
I removed the bolts that bolt the nose cone assembly to the blower housing. Then instead of separating the nose cone at the gear drive flange, it separated at the flange to blower housing. The roots come out with the flange/gear drive assembly, but I just placed it on rags on the floor and then separated the nose cone from the gear drive flange.
I replaced the spacer that connects the pulley to the gear drive and then cleaned the inside of the nose cone assembly. Then I put anarobic sealer on the both flanges and installed the 4 oz of fluid while it was upside down (fill plug right side up) and then bolted it back onto the supercharger housing. All without getting any oil on my motor....:thumb3:
