I need to oil the motor bearings on my10-e24-1b day night elect furnace

How old is the furnace? Newer furnace motor's have sealed bearings and can't be oiled.

Its got to be about 1970

WOW! Over 40 years old. Is this a gas furnace? On most unit's the blower section would have to be removed for access.

The blower case states I need to oil the motor bearings... but it seems like I would have to remove the whole thing.. perplexed.. it started squeeling..this is elect

Yea the blower section is probably original, but I'll bet the motor is newer. You could spray some WD 40 in there and see if that stop's the squealing. Check to see if the motor is screwed down tightly. It could be the blower wheel is rubbing the housing.
