1980s Whirlpool Imperial Seventy - Oil on floor

[114jwh]

285134 is the correct kit for the seals. It covers older and newer machines so there will be some parts you won't use. I wouldn't replace the bearings unless yours are badly worn, that requires a special tool.

383928 / 285896 I believe is the short post spin tube. Will likely need to find that on eBay as it is probably NLA. And for that matter, compare the price of a whole new basket drive which will include a new spin tube vs the spin tube by itself.

Agitator shaft will likely be more difficult to find.

I would also get a new agitator spring/seal kit 285672 since you are opening up the transmission anyway. They aren't usually that expensive and your spring may be rusty by now and the spring can sometimes break anyway.

But, if it were me I would still pull out the basket and inspect the outer tub real good before you start ordering parts. If its salvageable you might want to replace a couple other things too depending on their condition when you take a look.

Good luck and let us know how it goes

Thanks for the guidance and the part numbers! The price of that basket drive alone ($160) is above what I would throw at this machine. I see the spin tubes on ebay though, about $50 for one of those. Looks like the agitator shafts run about $100.

I will remove the basket and give the machine a thorough inspection, hopefully sometime this week. Might just drive this machine till the wheels fall off if things look bad...

Is the knock in the gearcase a big concern? On that a-1appliance parts site I see a price of $56 for the connecting rod (76577 - special order) but only five cents for the main gear (353397 - in stock). Of course I am just guessing that the knock is due to wear of one of these components.

Sean, I checked the setscrew on the pulley and it is tight.

Ahh. Good thing the set screw is tight, not sure what that knocking sound is inside the transmission.

If you are wondering, this is what my Whirlpool looks like. Took this photo in the driveway since it was the only place I could get a good photo of them. Not trying to take the spotlight, just want to post a picture for some context.

Very cool washer/dryer set Sean!!! Obviously if mine looked like that I would do whatever it takes to keep them going. I don't have any retro appliances in my place (it is all 80s vintage), but can showoff my Mom's 1950s GE Liberator stove that she kept going for 60 years. It was sold with the house back in 2021.

Back on topic, what about using a needle nozzle grease gun tip to sneak past the seals and inject grease into the upper bearing area? Or maybe packing heavy grease into the open space near the top of the drive black and trying to keep in in there with RTV silicone in strategic locations? Just trying to MacGyver my way out of this....

Hi Andy, you should just run it till it dies or tear it apart and rebuild it. None of these stop gap measures are going to buy you more than some time, There is water around the agitator shaft and in the transmission, seal it up and sealing the water in. There will only make things worse.

If this were somebody dying of cancer, I would understand going to these Extreme measures to get them a few more weeks or even months of life, but it’s a washing machine washing machines are very plentiful in this country both used and knew alike.

Right now I am on the run-it-till-it-dies side of the fence with this machine unless things look decent when I remove the basket and the fixes are easy. The rusty nature of the water that leaked out on Sunday is probably not a good sign. I am very concerned about any disassembly procedures that involve large hammers on 40-year old metal, but saw that I can pull the drive block up along with the basket using a 3-jaw puller so I will go that route. I will try an air chisel to remove the locknut.

I also put together a 1/2 inch diameter rubber expansion plug today and will pick up some VR1 60W tomorrow. The future drain hole location is marked in red. I think this is above the drive gear and far enough away from the connecting rod, but LMK if I am wrong about that. The expansion plug should protrude about 1/4 inch inside of the cover when installed.

Hi Andy

To take the basket off you just need to remove the snubber, the fill hose, the tub ring, agitator and then the spanner nut. Use a bit of penetrating oil if the spanner nut is difficult. If you don't have the spanner wrench you can sometimes just get these off with a large flat blade screwdriver wedged in one of the notches and a hammer or one of those giant vice grip pliers.

One the spanner nut is off, the basket should just lift out but might be a bit stuck due to crud so might need a bit of coaxing. You don't need to take the drive block off but it might just lift off with the basket. Its not pressed into place but again, could be stuck a bit due to crud.

It looks like you already had the agitator off. When you mentioned needing a puller are you referring to the agitator lug drive (or agitator drive block)? If so you wouldn't have that, those are on older machines - your agitator is pressed directly onto the agitator shaft.

I had some time today to remove the basket and inspect the tub. Had to use an air chisel to remove the locknut and the tub lifted off easily. See photos of seals, I think I see the edge of corrosion on the shafts but IMO they don't look too bad. Pump inlet has a lot of rust. Rust on the inside bottom of the basket too.

I cleaned up the disgusting 1/2 inch thick layer of sludge at the bottom of the tub and saw even more rust. I was wondering if this was acting as a barrier so I filled the tub up and there were water leaks after a few minutes, but this time instead of dripping on the gearcase the water was leaking out of drilled holes in the platform at the front and rear of the machine. Not sure if this is the same leak or a new leak.

I drained the machine and went to work with a wire wheel to remove all the loose rust and got down to areas that were rusted clear thru. Cleaned all this with alcohol and then sprayed it with rust converter. After this cures I will spread epoxy putty over the bad areas where needed, and topcoat it with something that is flexible and seals. I think I have a can of that!

I am not going to bother changing shaft seals on this one because I think it is too much of a basket case. A rusty basket case. At this point I am just trying to get it back to the point where it works again without massively leaking so we can take our time replacing it, probably in the next few weeks. I might have to rush with a new washer though.

LMK if you guys want any more updates on this project! And thanks for putting up with me and for all of your advice.

Hello again belt-drive fans.......it has been a while! Andy here, but this time with a different username because for some reason I couldn't login or recover the old one. It is now a year later and believe it or not we still have the 40-year old Whirlpool and I just finished rebuilding it. Thank you for all of the guidance, especially the part numbers necessary to repair it. I probably spent $100 total on supplies, which included the centerpost bearing kit with seals (285134 - $14), a new spin tube (383928 - $32), the agitator shaft spring & seal (285672 - $9), and some extra seals for the shaft (91939 - 4 for $16). For the gearcase oil I used Valvoline VR1 (SAE 60 racing oil with anti-foaming agents - $11 at NAPA), and to lube the new bearings and seals I used 3-in-1 oil "for motors" (SAE 20 - $7 at Lowes).

Last year I initially thought the machine was too rusty but when I really examined it the rust condition wasn't too bad. A year ago I fixed the holes in the basket near the pump inlet and center post with rust converter and epoxy putty, and sprayed a thick coating of Flexseal over the inside bottom surface of the drum making sure to coat the center post too. I also added a hollow rubber cup to the area above the uppermost seal in the spin tube and would pack the inside of this cup with tacky grease every so often to keep water from leaking down the shaft. This seemed to help for a while, but I was honestly slacking on checking this every week and the tray I put underneath the machine started to collect more and more water mixed with tacky grease that pushed thru during hot loads. In addition to that, the knock I was hearing from the gearcase during agitation seemed to be getting louder and louder so it was time to pull the machine apart and see if I could fix it.

 

[andy_70imperial]

My laundry room is upstairs and my workshop is in the basement (and the washer is heavy!) so to lighten the load I removed the top of the cabinet, the impeller, and the basket and moved the machine downstairs with a hand truck. To remove the gearcase I packed the area between the drum and cabinet with rolled-up jeans to keep it from flopping around and turned the entire machine upside-down to make it easier to work on. I pulled the gearcase and basket drive out as an assembly. The new spin tube came with bearing and seals already installed, but I wasn't able to easily find a new agitator shaft. Because of this my plan was to measure everything and re-use the original agitator shaft, but position the spin tube seals so they would not ride over any damaged surfaces. The locations of the seals in the new spin tube actually looked pretty good out of the box, but I drove the topmost seal a little bit lower and added a second one (91939) so both seal lips would ride on smooth sections of the old agitator shaft. I packed the area between these two seals with grease.

 

[andy_70imperial]

The new bearing kit came with instructions, very helpful! I didn't have access to the special Robinair bearing remover/installer tool so cobbled something together using a 1/2-inch threaded rod and stuff in my stash. This is where it pays to be a packrat. I found some metal tubing that was perfect for installing new seals, and was able to modify some heavy steel washers so they could be snuck into the center tube for removal of the bottom bearing. In addition to using the threaded rod to remove and install the new bearings I used it to install the new centerpost seals. This worked much better than trying to tap them in with a mallet.

 

[andy_70imperial]

The inside of the gearcase was a mess. The top 2/3 was filled with clear water, and the bottom 1/3 with brown sludgy grease. I was able to mostly clean this with rags and q-tips, followed by a light wash with brakeclean. Sorry I didn't get any photos of this, my hands were way too dirty to grab the cellphone. All of the gears and other moving parts looked great but the agitator spring was rusted out and collapsed, which I believe is the source of the knock I was hearing. That collapsed spring was barely exerting any force which I guess could lead to the big pin at the bottom of the agitator shaft flopping around in those slots that are machined in the bottom of the gear during the agitation cycle. I disassembled the basket drive and swapped out the old spin tube for the new one. Used some clamps to compress the assembly when re-installing the setscrew. Believe it or not the old belt looked decent so I reused it! A new one would put me over that $100 threshold lol.

 

[andy_70imperial]

It took all of my strength to move the cabinet back upstairs, and this is without any of the big parts installed in it. During re-assembly I clamped a wooden box to the side of the cabinet so I could tip the machine to a 45-degree angle and slowly introduce the rebuilt gearcase assembly as a unit and oil the upper and lower bearings when the shafts were in the optimal positions to do this.

 

[andy_70imperial]

The only hiccup I ran into was when I first fired the machine back up. During the first run it sounded like the motor was working harder, and there were even tiny bits of rubber flaking off the old belt. Not a good sign! When it was time to go into the spin cycle the machine completely locked up and threw the belt off the motor pulley, uh oh! I unplugged the power and noticed that the cam bar for spin would barely move.....it was totally locked up and I had to really apply a lot of force to the main drive pulley to manually crank the gears and move the cam bar back to the non-spin position. I was scratching my head trying to figure out what was going on and ultimately had to add two additional shims (i.e. thin hexnuts) to the pin under the brake yoke so the gap between the basket drive pulley and plate were correct (1/16 inch gap during agitation). Without this mod it seemed like the basket drive was dragging on both ends, like it was trying to spin at the same time the brake was applied. I guess the drilled hole in the new spin tube is off by a little bit? Like 1/16 inch too low??? Whatever the situation with those two extra shims the main pulley moves much easier, the cam bar action is smooth, and the machine even correctly brakes when you open the lid during the spin cycle.

Andy - great to see this thread resurrected and happy for you that you decided to rebuild after all and your machine is up and running again. These were built to be repaired and although it takes a bit of time, if you can find all the parts you need, centerpost and outer tub are salvageable and you are mechanically inclined, you can certainly get good results like you did. Super impressed on the ingenuity to create an installer tool and thank you for taking the time to document your rebuild with great descriptions and photos. I'm certain this will help someone else down the road.

Great job and once again, congrats on a successful project!

Thanks! Your post in this thread with the part numbers (post #21) was extremely helpful.

A little hiccup on the job though. When I swapped the spin tube in the basket drive assembly the two thrust washers on either side of the pulley were extremely thin (PN 353320) and one of them cracked but I re-used them anyway. On load #10 half of the cracked one spat on the floor during agitation and now the machine is making a "loose pulley sound" during everything but spin. I have four of the thrust washers on order now (two for the job plus two spares) and I have a new belt too so will install the new thrust washers when I change the belt later this week.

Are the extra hex-nut shims that I had to install out of the ordinary? When the machine is agitating it looks like there is a 1/16 inch gap between the smooth surface on the top of the spin pulley and those three round friction pads that engage during spin.
