But just for my education, what exactly is wrong so that there is lack
of lubrication?

Say, why are the bearings in my 59 year old compressor working great
and this fridge is dead at a relatively young age? (well, I know why
my compressor is going well, because the pumpbearings are pressure
lubricated).

Are there any "well made" refrigerators where things are designed to
last long?



A chip of grunge in one of the oiler holes on one of the crank bearings
or the motor tailshaft bearing can cause the problem. It can happen in
older units, too, but less often because everything was over-built back
when.

It's not a stretch for a guy with your skills to change the compressor --
say, with one from a 20-year-old fridge. You'd need the tools to
evacuate the system. You'd need to install access valves. You'd need to
either find a "friendly" with some R-22, or replace the charge with
propane.

But generally, a fridge isn't worth the work, when you can get another
one for under $100.

I've yet to see an old refrigeration unit that used R22 since R12 was
the first of its type. I use something called R416a in place of R12
and it's more efficient, takes less refrigerant to do the same job
and it runs a lower head pressure which makes it good for old systems
because it puts less of a load on them. Oh yea, it's a drop in, no oil
change necessary.
