Since I rebuilt the transmission on my Whirlpool over 2 1/2 years ago, gear oil is more sticky and is designed to ‘climb up’ moving gears inside a gear box wether it be a automobile manual transmission or a transmission inside a washer. On the input gear on a Whirlpool belt drive transmission (the pulley the gear attaches to), there’s a spiral pattern which pushes oil down into a area where there’s a small hole oil comes out which is a primitive sort of oil pump, my guess is Whirlpool built their belt drive transmissions to be backwards compatible with other oils which were non-detergent motor oils. Not sure if that’s correct, but it could be a possibility judging by the things I observed over 2 years ago. As for motor/engine oils, they have to be a certain viscosity since the oil has to be able to flow correctly at low and high temperatures through the main crankshaft and camshaft journals, especially important with modern engines with variable valve timing and overhead cams. Push rod overhead valve engines can get away with using a thinker oil if there’s significant wear and noise since there’s no overhead cams to lubricate, just the rocker arms for the intake and exhaust valves. Definitely won’t be good news to use thinker oils in modern overhead cam engines with variable valve timing since there’s very fine oil passages for the various parts and such.

John, I think I know what Jerome is referring to. One can smell the warm gear oil in some machines while they are running. Come to think of it, the filter flow is a prominent example of this, especially during the spin cycle. I just never really thought about it until this thread.
I did notice a really strong gear oil smell during the last few months of using my direct drive, but come to find out the transmission I bought 11 months ago was leaking oil. Ugh. Ryne | ||

Oil smell
A GE Filter-flo washer transmission is sealed and does not have a vent hole like a Whirlpool transmission, unless you have an oil leak, I don't see how you can smell the oil. My guess in what your smelling is coming from the warm motor bearings, this could explain why both washers smell the same. I have been working on washer for over 50 years, and have a very good sense of smell, and have never smelled transmission oil from any washer unless it had a large leak.

whatever it is... You can tell it has an industrial smell in both machines. I could smell it whether I had an oil leak or not. I believe both heated their oil during operation. | ||

gear oil I suspect that GE and Whirlpool both use steel gears, with Whirlpool also using a durable plastic gear. Maybe whoever supplied the oil for their transmissions worked with both companies. | ||
