My problem is that the front bearing of my supercharger is getting noisy. The engine see attached picture (pre supercharger) is fitted on a 15 degree angle, and I think that the front bearing is now starved of oil.
How is the front bearing in the snout of these superchargers lubricated? The oil level is just below the bearing height and I am wondering if the front bearing is actually packed in grease. Or does the oil get splashed around and work its way up there?
I could overfill the housing if I tapped a hole a put a fill bung in the top of the gearcase, however how do these blowers breath as the oil expands. I thought with the small amount of oil in them they don't need a breather. If I did run more oil in it, I would need to fit a breather in my new fill hole? Or are they connected to the pressure side of the inlet tract so pressure equalizes between the gearcase and the inside of the rotor housing like the toyota s12 & s14 blowers so the seals have no pressure difference either side of them?
Anyone got any ideas/ answers??
Thanks,
Andrew.
