When I just finished my trommel, I had a gear reduction motor that I
used. Apparently, it had never been used, as there was no oil in it,
and I do mean DRY. I put some 30 wt in there, what I had. I have used
it about four hours now. Should I put any special oil in there, and if
I do switch oils, do I need to flush the old oil out, and with what?
30wt oil is certainly better than NO oil, but gear boxes usually use a
much heavier weight oil.
Go to the mfg's website and have a look at the service manual for your
particular device. Assuming you need to use heavier oil I do not think
you'd need to flush your system...merely draining it and properly
disposing of the old oil should suffice.
Guess I could look up "trommel". I'd also been
thinking heaver. What's the speed of the box?
Slow speed, or high? Might work on hypoid
Fill with large hypoidermic syringe.
Hypoidermic, get it?
What ever you use, be sure it is not regular motor oil. Should be
non-detergent. If the machine is subject to relay heavy loading, use
"gear oil". If lightly loaded, use something like air compressor oil.
If there are seals on the bearings, they may leak for awhile, but should
expand when they absorb oil and stop leaking.
What is a "trommel"?
I was curious enough to look it up. It's a rotating cylinder used
to separate material by size. Trommels vary tremendously by size. It
is a grain cleaner in the farming world. One purpose would be to
separate the wheat from the chaff.
I went to high school with a Trommel! In the farming world, grain is
cleaned from chaff using adjustable screens and a fan. The cylinder in a
combine is used to beat the grain off the straw. It and the screens are
Still need more info one the speed, in and out of the gear reduction,
and does it use straight gears, bevel gears or worm gears. Each needs a
different type of oil.
Basically, a spinning tube with holes in it so that one can separate
different sizes of materials, commonly used in mining to separate rocks
from fine ore bearing sized pieces of material. Also called a classifier.
Oh, goody. We can disband the group. Everyone go home. There's no
need for the group. We can just go to Google.
philo, ever been to Google? Yes, sometimes you can find what you're
looking for. Other times, it is like looking for a particular grain of
sand at the beach.
If you don't like open discussion, and asking questions, buzz off.
Those of us here who don't know everything sure do bother you who do,
There is another plus to asking advice here vs. Google or whatever.
It's someone offering an alternative solution that the OP hasn't thought
of. Even the silliest sounding idea helps sometimes if it makes one
think of alternatives. Two or ten silly ideas might combine to form a
This gives me an excuse to mention the series Connections by James
Burke. He'd start each show by or in a modern invention then show all
the odd things that came together to make the invention possible.

Thank you for your support. I don't know about you, but I absolutely
hate the new Bing thing. Talk about finding a clamshell at the beach!
But they make it necessary for you to wade through layers upon layers of
ads before you even get to choose the search terms for what you are
looking for. And about that. "Gear reduction motor oil" will get you
hits about hiking GEAR, breast REDUCTION, penis pump MOTORS, and KY
LUBRICATING OIL before you ever get into metal related stuff because
they are all based on number of hits. And, as you say, someone can come
up with a solution akin to adding oatmeal, or something wild that one
would never think of to solve a particular situation. I do love Google,
but IT IS AN ADVERTISING MEDIA, and has grown a lot towards that bent
since it started, IIRC.
I doubt it would stop the action as Goodwin says. In fact, maybe the
I'm not sure how Young's Law would apply here. Maybe all the posts
could be viewed as droplets?
But, I read about the Wizard's first rule long ago in a science fiction
book. His first rule was people are stupid. That is they will say
and/or believe anything.
