OK guys, I'm going thru my GMC blower, new bearings, seals, resurfacing the end plates, etc, etc....question is after assy/install what gear oil/lube are you guys running? and to what level are you filling the end plate?, just under the shafts?...I'm also running the rear factory blower plate, even though the bearings are sealed should I maintain an oil/lube level in the rear plate as well?...any help is much appreciated

Mike

I was told 75/90 till it comes out the 8' oclock bolt position on the front cover.

Oil level needs to be high enough to reach the bottom of the drive gear so it will "sling" the oil around

HEMI-ITIS has no cure.
My condition is fully BLOWN!!

No relief button, should I use one? will the pressure be that much in the front cover?...this is the type of blower case, plate. cover that I have, also have the same "smooth" style bearing plate in the rear, with sealed bearings, seals, and 3 bolt retainer plates holding the bearings in, I have a cast finned cover sealing the rear bearing plate, I know I could possibly eliminate the rear plate, and use the rear cast finned BDS plate to mount the rear bearings, but if I decide to use the factory end plate along with the BDS finned rear plate, I don't need fluid/oil in the rear bearing assy?


Thanks for any input
Mike

you realy should have a pressure relief valve.the blower makes heat and forces iol into the case past the front seals.
