Originally, I didn't think my Leyden's convection blower had any oil ports. Toward the end of last season I noticed it did, but they were pointing down. I took out the blower and oiled it and put it back in for the remainder of the season. With the ports pointing down I doubt my bearings got much oil, and it was apparent that most of the oil had dripped out. Today I took the blower out, removed the comb fan, removed the motor from the scroll cage and rotated it up so that the oil would drain toward the bearings. It was a fairly simple process. Look at yours first of course and if ok great, maybe mine just got assembled by an idiot?
Below shows the complete blower, the scroll cage with the comb fan removed, a picture of the original orientation of the oil ports pointing down, a picture of the motor rotated and the new oil port orientation, and the modified blower reinstalled.
After you remove the blower you will need a T-20 torx bit to remove the comb fan, the collar is not an allen set screw. Under the comb fan are 4 hex nuts (11/32" socket drive) that attach the motor to the scroll cage. Be careful, under the washers are rubber gromets with small spacers in them. Pull the motor away from the scroll cage, rotate the motor (clockwise in my case), realign the holes and reattach the nuts. Put the comb fan back on and reassemble. I only rotated it slightly, and it did not put the oil ports on the top. I preferred the port angled.
Anyway, that's all I have, just wanted to share, pay back to the forum, and maybe help someone out before their blower craps out.
