8V92 Oil

In case you have a 149 series in your bus, 50 weight is also recommended (LOL). Good Luck, TomC

TomC,
You got it, I stayed clear of the 149 & 278A series, but had to get into the 110 series in case  you need any timing pins for a 110 ?.
Think can still find a few.
The reason for the 50 is better proven luck on the 8V-92 rear main, the 6V does not seem to have the issue.
As for the AT&T operation, my guess it was with the 12V-71 or 16V-71 as the71 series does not have the rear main issue like the 92, the part is a generator has a different duty cycle than a highway engine, like never being loaded under 1800 rpm etc, etc. when oil pressure is lower, off idle WOT.
Just another experienced view.

Worked around the 12v71 generators at our hospitals.  they were tested once a week. 0 to 18oo rpm in a instance. if not special detroit men were sent to check.

Not a room to be in pulling telephone wire through during a lightning storm.

instance hearing problem.
