Slowly Replacing Bearings on a Kenmore 70 Series

[candi]

Hi all!

After reading through Potatochips's rebuild more times than I will own up to, I think I finally understand this process. I expect to go slowly and update this thread through the process.

To start, here's my Amazon order: bearing kit, belt, tub grommet, spanner wrench, tub seal, and air wedge set (my agitator is stuck). Anything I should add?

I do need the rubberized spray and rykon grease substitute, but I'm not sure which ones to choose. I was thinking the Rustoleum Leak Seal and a tube of the Lukas Oil White Lithium Grease. Are these good, long-lasting choices? Should I choose a different grease, since there are rubber parts involved?

Then there's the bearing puller and installer... does anyone have these elusive tools for loan?

Thanks again for all y'alls help!

Have fun!

Thanks! I'm kind of excited to have this tale to tell

Glad to hear you are giving your trusty machine a new lease on life! Kevin did a great job on his videos documenting his belt drive rebuild.

I have the following PN's for the bearing tools. There may have been other PN's too:

14857 Bearing installer tool (or 14542)
14510 Bearing puller tool

The tools were built by Robinair. As I understand, these have been NLA for at least a decade (probably 2) however they may show up from time to time on eBay. If you can find an appliance repair business locally that has been around forever they may still have these tools they could lend you, especially if you decided to buy the parts from them. I'd get out the trusty old yellow pages and start calling around.

The installation tool would be more of the priority as you can probably make do if necessary without the puller. I didn't have one for my rebuild but my bearings ended up coming out with the spin tube.

Keep us in the loop on your progress!

Rebuilding A BD Whirlpool Built Washer

Hi Having rebuilt 100s of these washers I will offer the following advice.

 

The grease is not hard to find, any good automotive wheel bearing grease is better than what WP used years ago.

 

I never bothered to use our bearing remover, it is easier to just pound them out, the installer is very useful.

 

Keep us posted I can answer any questions that you come up with.

Question about the grease

I'm trying to conceptualize this process while I wait for my parts to come. [Unfortunately, my water shut off valves are seized, and I'll have to turn off the water to the house when I do this work. So, I want to be quick and efficient once I start.]

First, a wire tube brush should be sufficient to clean out the centerpost, right?

Next, I've got a pouch of grease and bottle of turbine oil. But where exactly do they go? Once I have the upper bearing and it's lower seal and the lower bearing and its lower seal on, I'm supposed to put 1/2 oz of grease into "the lower centerpost bearing section" before reinstalling the gearcase. But I dunno what that means. Am i just smearing a tbsp of grease inside the lower brass tube and rubber seal? Won't it gush all around when I reinsert the spin tube?

Then, once I have the gearcase back on, I'm to fill the space between the upper bearing and the spin tube with turbine oil, right? After that, I put on the two domed upper seals. Do I grease one and oil the other? Which seal gets which lube? And where exactly do I put it?

Well, in spite of my (possibly silly) questions, I'm pretty stoked to get this done. My other task while I wait is to call around and find that installer tool!

Ps. Thanks guys for your help and continued interest in my project!

Tools and parts have arrived!

It's been a couple of weeks, and all my parts and tools have arrived!

I'm not sure if I got new old stock, but I found the bearing installer at a place in Quebec! I felt like I had won some type of lottery. (Ps. It didn't come with a thrust washer. Is it supposed to?)

I've yet to find some type of pipe or dowel to use to pound out the old bearings, but after that I'll be good to go. I'll probably work on this next week, when my sister will be available for moral support.

I'm still not sure of where to put all the grease and oil. I'm thinking the process is: grease the insides of the lower bearing, install the centerpost, fill the space inside the upper bearing with turbine oil, then put on the two seals. But they're supposed to have grease and oil too! And I can't figure out how that will go.

Well, that's all for today's update. More to come soon!

That's great news you found the bearing installer - the belt drive design was around longer in Canada than the US so some parts may be easier to find up this way.

Hopefully you got a new Spin Tube? That will definitely be a must if you are going as far as replacing the bearings. I believe I've read in John or Gordon's posts that the old spin tube can be used to pound the old bearings out. A new agitator shaft should also be considered for a rebuild.

 

[candi]

Sadly, I don't feel comfortable getting too deep. Dropping the transmission to change the bearings is at the far end of my current comfort level

But, once done, I might continue to learn until I can change those things. Maybe....

Get a new spin tube. I made that mistake with my 65 Lady Kenmore  - I did the bearings then used the original spin tube and after 4 years of regular but not excessive use, the washer wouldn't spin anymore!  I am amazed that you found a bearing tool in Québec! I needed one desperately 2 years ago and I couldn't find one!  A friend in Nova Scotia graciously sent me his spare!

I would think about reconsidering the spin tube. Replacing it will be the easy part of the job. You will need to take out the transmission anyway to replace the bearings and I expect that you'll find out that there will be corrosion on the tube. Imperfections on the spin tube will damage your brand new bearings.

Depending on the age of the machine you will need one of these two:

383921 - Long Spin Tube used on older machines

383928 - Short Spin Tube used on later machines

If you want to go a step further you could just buy a new basket drive and a new spin tube will already be installed on it. Then its just a matter of swapping it with the old one when you get the transmission out.

There were many different configurations of basket drives depending on the age of the machine and whether it uses a standard belt or the narrow one. Someone on here will be able to direct you on the right one if you decide to go this route.

Oh dear...

It wasn't the plan, but looking back at Potatochips's video, I think I can do this too

Since I don't see the parts listed on the diagram that I've been using, I did a little googling and found a place in the area that can hopefully help me determine what size tube I need. I'll probably get the tube and the basket drive.

Thanks for your warning!

Ps. It was a place called Midbec. They sell tools and appliance parts. I had googled the part number so many times, but eventually they came up in the search. Super helpful staff.

The *only* correct way IMO to do a bearing replacement on a belt-drive (or direct-drive) WP is by replacing both the bearings and the spin tube, and possibly the agitator shaft, so that both the bearings and drive shaft surfaces that mate to them are fresh.  The spin tube includes agitator shaft bearings already in place for direct-drives, so I assume also for belt-drives.

Bearings fail less often on direct-drives.  The tub support, which incorporates the centerpost and includes bearings already in place (but the top seal has to be installed, and turbine oil added) is still available ... unlike belt-drive baseplates which are NLA unless one finds NOS or a donor.

Basket Drive

I just looked at your original thread - the model number you indicated is 11082372110? If this is correct, looking this up on Sears parts site shows the basket drive as PN 359699. Using this PN it subs to 285897 and 383929. Looks like this is a short spin tube, standard belt pulley and large capacity. One of the others here can hopefully confirm but if so, there are a few on eBay listed under the 383929 PN such as the one in the link below.

BTW, if you buy a the complete basket drive assembly, such as the one below, you don't need to buy a new spin tube. The basket drive assembly will come with a brand new spin tube already installed on it. When you take out the transmission you will just swap the old basket drive assembly with the new one.

Pardon Our Interruption...

 

[114jwh]

And like I mentioned, you don't need to buy the spin tube if you get the whole basket drive assembly. The basket drive assembly will have a brand new spin tube pre-installed on it for you. All you need to do is swap the new basket drive with the old one when you take out the transmission.

Good luck!

Hello!

 

Amre Supply is also another resource for good parts, and I believe they have lots of basket drives of short and long tubes in stock. Midbec has also been very good to me as well.

 

If you get all the right parts, but the spin tube length is wrong, you can swap out a long tube for a short tube. This is what I had to do as most Canadian Kenmore machines are quiet pak drives with short tubes. The short tube I ordered had a wide, normal pulley and I had to reassemble it with the quiet pak pulley.

 

As everyone has said, it is imperative you get new bearings and a new spin tube. They need to run in together and mate properly, if not you can wear out one or the other faster and have to redo this job. The old spin tube I had was gouged and worn down, so I turned it in to a lamp.

Choosing a basket drive

Thanks for the help on the part number substitution. When I looked at the diagram, I thought that the arrow was only for the small piece it was pointing to, instead of the whole assembly

To be sure of the tube length, I went downstairs to measure, and the agitator is more stuck than I thought! Grumble. So, I have my air wedges wedging and some WD-40 soaking (it's all I have on hand).

I see two, short-tube basket drives on eBay. One is a genuine factory part and the other (at half of that price) is by Gemline.

Is the genuine part genuinely (heh...) better, or are they equivalent? I'm not trying to cheap out so much as I don't want to waste money.

Thanks again, guys!

Aftermarket Gemline Basket Drive

I used a aftermarket spin tube on a rebuild I did and although the quality seemed to be on par, the fit was ever so slightly off that I did need to sand it a bit to get it to work. It was no big deal and it worked perfectly fine after that so all was good. Others with more experience can probably chime in on their experiences with Gemline/Supco and offer some insight, specifically on the basket drives.

This is a dumb question but did you take the cap off the agitator first? With the ones I've had experience with, some have a cap that screws off, some have a very short cap that you pry off to access a screw or nut underneath.

What year is your machine? I think I've read that Whirlpool changed from the long post to short post machines in 1978 in the USA. Inglis used the long post design for a few more years in Canada before switching over.
