Generator end plate bushing lubrication

[Jonas A]

Hi!
How is the generator end plate bushing lubricated?
There is a oil cup on the upper side and a oil wick in the bottom.

But how does the lubrication reach the axle!?
There is no hole in the bushing and it blocks the oil wick/oil cup...

What am I missing? :-)

The bushing is made of compressed and bonded little pieces and has small voids that oil wicks through

Thanks,

Thought about that but didnt think it looked porous enough...

Sintered bronze, commonly known as "oil lite". Think tiny bronze beads all stuck together with voids between.

That bushing needs very little oil. I restore these generators and have seen more than a few that were sopping wet with oil from over oiling.

I am finished installing a new bushing and the end plate is sitting on my kitchen stove. The bushing has Liquid Wrench thin oil soaking into it and on my next day off I’ll use it. I did not drill a hole from the oil port through the bushing wall.

Don't over oil the bushing. A few drops of 30wt is all you need. Put too much in and it will sling all over the inside. Be sure to unscrew the oil cup and saturate the felt with 30wt too.

Are all brass bushings sintered?

AI Overview
No, not all brass or bronze bushings are sintered. While sintered (powder metallurgy) bushings are very common for self-lubricating, "oil-lite" applications, many bronze and brass bushings are also produced as cast or solid machined components. Sintered versions are porous to hold oil, while solid versions are stronger for high-load, heavy-duty uses.
