So's I don't thread crap in the Dyno thread with my blower issues, I'll start a new thread.
I've had a few hours of thinking time now and used our friendly sccoa search button to see just what may be up with my blower and the noises it makes.
The knocking sound it's had for the past short while sounds like it may be the coupler going bad. The growling sound that just started sounds exactly like one would expect bad bearings to sound like. Very much like the sound you hear from bad wheel bearings.
The fluid is low (no leakage) and is black as coal. The last time I had the plenum on the rear of the blower off, I noticed a lot of oily residue on the exposed ends of the rotors. After seeing the fluid today, it looks like the same fluid I noticed on the rotor ends and inside the case when I had the plenum off. (It's not blow-by oil as I have a pcv filter).
1) I'll try replacing the fluid to see if there is any change in the noise.
2) I'll contact Magnum Powers first thing Monday to see what he thinks and what can be done by him or myself keeping the dyno date in mind.
The blower has about 1000 k on it at most.
Would the fluid be black?
Would a bad coupler or bearings break apart and damage anything (engine)?
I've never had the front end of a M90 open so I don't know what any of these parts look like.
If I was able to get rebuild/replacement parts overnighted, could I or whit help from someone that's been there/done that get the blower back into operation before friday?
