I removed the blower with the bracket in place:


Some of the oil:

It came out green and thick. Smelled like crap too. I'm not sure what Comptech uses but the Ford/GM supercharger oil is clear.



Unbolt cover and pull it apart. Pull it out carefully and do not use a screw driver to pry it apart... you'll damage the mating surfaces and ruin the seal.






Nice and clean:


Reseal with Loctite 548:




Torqued the cover bolts to to 15 ft/lbs and allen head screws to 10 ft/lbs. Opened up the fill hole (standard size allen bolt, not metric). Then sat the supercharger on its end and refilled with two bottles of GM supercharger oil (118 mL each). This was enough to cover the gears and a bit more (about 5/8" from the top of the fill hole). I remounted the supercharger with the bracket it on so there is no risk of breaking the seal. It makes wrestling the ac line a bit less worrysome.

 

Very Nice

MODS - I think this DIY deserves a move to the Archive for future reference. This is the first time I've seen the inside of the Blower.

 

BTW, the green coupler is for a Grand Prix M90 supercharger (aftermarket coupler). I got it to check to see if it fit ours and it doesn't seem like it fits. I didn't try too hard though.

 

Are all supercharger oils the same?

 

I heard that the GM & Ford stuff is the same stuff that Eaton recommends. Comptech probably uses the same stuff. Used Eaton supercharger oil is green and stinky so thats normal. I don't know how long it takes it to turn green though.

 

If someone reads this DO NOT put more than 180ml of supercharger oil. According to a Magnuson blower will make too much pressure and it will blow the seals again.

 

I just called Comptech...this statement is verified. 180mL it is. He further mentioned in case you don't use the above method, and simply drain it from the fill/drain plug, only put in as much as you take out. Meaning that if you only drained 100mL (basically stating you didn't drain it all for example even though you felt you did), only put 100mL back in.
