Currently in the process of putting the original transmission back together out of my 1963 RCA Whirlpool Imperial Mark XII washer. My question is will Valvoline 50 racing oil work? Reason why I am asking is Gordon (kenmoreguy64) mentioned somewhere in a thread in the archives that he would try using Valvoline 50 weight racing oil since it’s light on detergent and is more easily available but I just want to double check since it’s been a number of years since there was a thread about transmission oil in Whirlpool belt drive washers.
 
Maybe I might use gear oil but I think it might drag on the gears putting strain on the belt and motor. The original gears out of the transmission to my 1963 Whirlpool don’t have much wear on them at all.

I finally ended up selecting the GL-4 Hypoid Gear Oil by Quicksilver 858064Q01 High Performance SAE 90 Gear Lube for Mercury Outboards.

I thought it might have some benefit or protection in case of water intrusion since it was formulated for outboard motor use.
 
Oil For WP BD Washer Transmissions

I would not use anything lighter than 70 weigh gear oil, but you could easily use 90-120 weight, it is not critical in a WP washer,

 

Even in cold environments WP washers like all other washers ever built will not have trouble agitating like Maytags with the silly slipping belt drive when you are trying to wash clothes.

And in the freezing cold, with a Whirlpool transmission full of molasses, the motor strains to spin up that transmission to full speed with no slippage, and the bearings and the seals are bound to suffer undue wear.

 

That "silly" slipping belt drive is just one of the reasons why heavily used Maytag machines outlived the others.

<strong>If a Maytag belt was adjusted as tight as a BD WP/KM, it wouldn't slip in cold temperatures either.</strong>

 

When I restored my 906 washer, I installed a new upper shaft and bearings in the upper transmission housing (the shaft was perfect and bearings were fine but I had them on hand, so why not?). I also wanted to experiment with 75/90 Royal Purple synthetic gear oil to see if it was a suitable replacement for the original Maytag oil since I was curious how it performed, knowing it was a matter of time before Whirlpool obsoleted it. During the winter as a torture test, I filled the washer full with water and let sit overnight in the garage to cold soak. Temperature of garage and machine were at 41F the following morning and the transmission banged right up to speed with no drag. When these machines are set up properly with the correct oil, one can have their cake and eat it too.

 

 
Another thing too is oil tends to thicken at time goes on. I put some Royal Purple gear oil in and it seems similar to motor oil but is more sticky than oily. I’ll see how it goes when I get the transmission installed but that won’t happen until later this week or next since I am waiting on the new spin clutch to arrive since the original clutch grabs a little too much when it engages into the spin and is abrupt at times but that should all be fixed when I get the new clutch installed.
 
Hi John, I am getting the 3 pad clutch you mentioned in the original thread about my 1963 Whirlpool Imperial Mark XII set since it allows everything to continue running at full speed when the spin engages without dragging or bogging anything down when the spin engages.
 
BD Washer Clutch

Are you getting a fast brake clutch and brake assembly or the regular clutch and brake ?

 

The FB is a little over 3" in diameter the regular clutch is over 4" in diameter, if you are converting to FB you need to change the spin cam-bar and use a hardened pin in the control-magnet plunger for the spin side.

 

Keep up the good work.

Hi John, I’ll have to see when the clutch arrives later this week. The clutch I ordered is the correct clutch and I don’t plan and changing any pulleys and I’ll take pictures of when I get the clutch installed on the spin tube and brake assembly.
 
Some photos of the new clutch. This should definitely work better than the older style of Whirlpool clutch from 1947 to 1967.

They switched to the 3 pad design since it allowed everything to continue running at full speed when the spin engaged and the older style of clutch tends to grab a little and bogs everything down when it engages into the spin which can cause a suds lock and the newer style of clutch can still suds lock but not as badly with the older style of Whirlpool clutch before 1968.
 
Got the new clutch installed and installed the external parts on the transmission. Only thing I have left to do is install it back in the machine and see how it works with the new clutch.

Here’s a video I made explaining how the spin works (requested by a viewer) and made videos showing my progress of getting it all back together. Everything seems to be working as it should and definitely works better with the new clutch and I had to adjust the clutch so it would engage properly.

 
Now here’s one observation I’ve noticed is you know how a Maytag helical transmission sounds when in operation? The transmission now makes a somewhat similar sound but that’s probably the gear oil doing it’s job by lubricating and sticking to the gears in operation.

So far I’ve ran 4 loads of laundry through it and definitely seems to be running smoother with the gear oil in it.

Why are you replying to a thread from last year? And keep replying to threads from years ago and asking the same question over and over again? I know you are anxious for answers but it will take patience and persistence to answer all the questions you have about gearnouls and how a Whirlpool direct drive transmission works.
 
gear oil reasons

The reasons why I'm stuck asking the question whether the GE filter-flo and the whirlpool direct drives use the same oil is because they smell the same. So it makes me wonder if they both use the same oil. It's a pressing question that nags me. When I sit in front of a whirlpool direct drive, I am immediately reminded of my GE filter-flo when I smell the gear oil while it's running.
 
Here’s a video of someone doing a oil change to a GE Filter Flo washer and doing other various repairs to it. It appears that STP oil is being used to replace whatever oil was in this transmission originally.
