Champion (Parnall) Spin-Washer - Disassembly.

[grnappliance]

Any updates on the Service Document info? I myself have been out of action for the week because of sickness, but I'm back up to strength and eager to resume my progress. No new changes to the machine have occurred since the last post.

Info

I’ve resent the info to your email address . Regards Darren

I've received the Service Manual. Thanks!

Looks like the first thing I must do is remove the "Agitator Head Plug Unit," which gives the appearance of a black cap on the shaft. Unsure of how to get it removed, but studying the diagram of parts in picture 1 shows me it might need to be unscrewed. A confirmation would be nice before I actually attempted that.

Part 247 in the diagram.

Is there a problem with the gear box ?

Is there a problem in the gear box ?

Whoops, I misunderstood the sequence. Turns out the agitator drive shaft doesn't need to come apart for the tub to be taken out.

According to Step 5. To Remove Basket Assembly, I will have to remove "12 mush. hd. screws from clamping ring," and the basket assembly will lift off. I circled these screws in red. It then goes on to say that you can take off the Basket Liner by removing the 6 Philips screws and nuts holding it in place, circled in yellow.

I'll do that later today, and once that's out, I'll need to figure out what to do next, perhaps step 6.

The tub might be stuck. I think it was designed to come off of the dome housing, but it stayed connected when I attempted to lift.

Update:

I pried off the metal ring, and it looks like I will also need to remove the 8 Philips screws holding the center in place. I thought the blue base was 2 pieces screwed together, but it looks like it's one piece. Anyhow, I'll still get those screws removed, and we'll see if it comes out then.

Screw Trouble

I got the Agitator Tube cleaned up as best as I could. I then proceeded to apply some WD-40 to the screws. They are unfortunately about to round out and are beyond my ability to loosen with my screwdriver without damaging them further. I really don't know how to solve that issue, so I'm getting ready to research some solutions. Any ideas?

 

[gizmo]

1. Clean out the slots in the top of the screws.

2. Soak in Inox, not WD40. Leave a day or two.

3. Try a selection of screwdriver bits to use in a cordless screwdriver/drill. Try both Phillips and Pozidriv bits, in several sizes each. Only one will fit Perfectly.

 

only trial-fit them first in the screw heads, don't use them in a driver/drill till you have chosen the perfect fit. This gives you the best chance of undoing the screws without damage.

 

4. Maybe try a cordless impact driver with the correct bit?

Tub removal

To get the tub and gear box out you need to remove the clutch housing and drive and brake cone from under the machine . The gear box and tub ( all attached ) will slide out upwards ..
I really wouldn’t open the bell housing on the gear box unless there is a known problem . Did you get the service manual okay ? The only time you would need to get the complete unit out is to service the snubber seal … call me if you get stuck . Regards Darren

I'm delighted to inform everyone of my progress. I took the day off to study Step 7 in the service manual, as well as the Clutch Helix and Brake assembly diagram on page 22.

I carefully laid the machine on its side and supported both tubs with towels. The manual was a tremendous help to me and allowed me to take apart the base with relative ease. I almost made an error standing the machine up to undo the clamp bar, as the tub and brake drum unexpectedly slid down, but everything appears to be fine.

Brake drum removed, I slid the tub, gearbox, and shaft out of the tub while it was on its side, reasoning that I probably wouldn't be able to lift it standing because of the weight. And there it was! The inner tub came right out of the machine, revealing the inside of the outer tub. It really isn't looking too bad in there, I can totally get that cleaned up just fine. I don't know how the tub seal is, but it'll be easier to tell once it's clean.

The rest of the disassembly is looking very much accomplishable, now that the tub, clutch, and brake assembly are finally out of the picture. I'm looking forward to resuming my progress tomorrow. Thanks Darren for the service manual!

Brilliant progress

Brilliant progress . Keep the restore going

 

[grnappliance]

Disassembly is pretty much complete now. I left the Snubber Seal assembly on the outer tub in just case it was one of those Do-Not-Disturb assemblies. The Motor, Capacitor, Pump, and Pressure container have all been removed from the base, and the outer tub has been disconnected from it as well.

 

[grnappliance]

I would like your thoughts on what to do with these parts from the machine. Regarding the transmission, would it still operate fine with half of its oil missing?

 

[slowspin66]

Oil level

Well done and good work stripping the machine . As the oil came down the side of the drive shaft I would try and replace the oil down the same way . You could make a small reservoir with a plastic bag and some strong elastic bands to allow the oil to seep down the drive shaft Do you have any idea how much oil you lost . The service document will tell you the quantity I think it was shell Trocus oil ?? Just an idea ?

 

[grnappliance]

Transmission update:

I don't think the source of the oil leak was from the drive shaft. A look at the bottom of the machine's agitator revealed no signs of oil runoff from the shaft. Furthermore, when I decided to investigate how much oil was left in the transmission by successfully removing the agitator tube, there turned out to be a lot more oil missing than I expected.

This uncertainty with the leak left me puzzled. The only theory I could think of was that oil came through the basket clamp ring via a leak in the main oil seal. I'm currently working on fixing this issue.

In other news, I will be beginning the cleanup process soon. Everything is just about organized for that to happen.

Hi Gabriel,

You are making fantastic progress with the Champion washer !! You have definitely taken on a challenge there and you have delved much deeper than i ever would with my Parnall Spinwasher.

Keep up the great work and look forward to seeing the working machine in due course.

Cheers
Keith

Snubber Seal

So the snubber seal is still in the outer tub, and I've been investigating it some more. It's probably a good idea to put a plastic bag over it during cleaning so that no water gets on the inside.

But after I clean the tub, the snubber seal is going to need some attention. The outer part of the seal looks fine to me, but the inner part does not. It's the complete opposite of dry, giving off an almost melted appearance. Perhaps the correct word is rotten. There are two visible tears in it, both small, but they will have to be addressed if the machine is to hold water properly.

I know how to remove the outer snubber so that I can look at repairing the inner seal, but first, I'll gather your thoughts.

Any seal progress

How did you get on with the seal issues it looks like the oil leak may have damaged the rubber ….. ?? It doesn’t look as bad and is repairable
…. Can you post some
More photos of the seal inside and out and also what’s the counter surface made of ?
Keep us posted Darren
