I once bought a bread machine, because delicious bread does not exist in nature in Novorossiysk. The model of this machine is Moulinex OW200030 / B72. She worked well, everything suited us, and suddenly something terrible happened - the bread pan began to leak. This happened 1 day before the end of the warranty period (1 year). In the warranty workshop, the faulty vat was changed in my presence, leaving the old vat too, which later came in handy. Guess from three tries, dear reader, how long did the new vat last ?? That's right - exactly one year! Then I began to think. Looking for a new vat? Nope, not that ... Will I spend time, money, and all this for just 1 year? Not, not that. Buy another model of bread machine? Not at all: a waste of several thousand rubles despite the fact that the electrical part of my car works fine. Repair the vat? Yes, this is the same, but how can you do it in the best way? And from this place, patient reader, if you are a female, most likely you will become bored, therefore I recommend inviting a man to the screen who is not a poet or composer.
So. I decided not to limit myself to half measures, but to radically change the design of the entire drive unit for the agitator of the vat, pursuing three goals:
1. Make the assembly collapsible for easy replacement and maintenance of parts.
2. To increase the reliability and durability of the unit.
3. Simplify the design.
To begin with, I drilled three rivets that attached the vat to the mixer drive housing. Drill from the BOTTOM, from the side of the drive housing! Drilling from above can ruin the thin, soft vat. Instead of rivets, I used stainless screws with self-locking stainless nuts.


Having ripped out the loose oil seal, I realized that the bushing in which the agitator axis rotates is surviving its last days, because the axle retaining ring has turned into dust (it is understandable - a galvanic couple between it and the STAINLESS axle), which spilled into the gap and ate the axle, and the sleeve. I pressed out the bushing and turned a part from fluoroplastic on a lathe, which I called the "bearing-stuffing box of the agitator shaft", because it combines 2 functions - a seal and a bearing:

In the first two photos, this detail is clearly visible - it is white. It is known that fluoroplastic has a very low coefficient of friction and very high heat resistance. Thus, I got rid of the need to lubricate the unit and use rare and short-lived oil seals.
Further. The old axle fell into disrepair, instead I turned a new one out of stainless steel 08X18H10, but any food grade stainless steel will do here. The axle was ground, and the drive engagement plate was welded to its end:

I refused the upper retaining ring: simplification of the design - one, easy-release axle - two! I made a flat on the axle for putting on the mixer itself with a file. I collected the bundle, poured water - a drop began to seep from below. Disassembled, it turned out that the old silicone gasket was to blame. Then I threw it away, and when assembling the unit, I smeared the housing of the mixer drive with construction silicone, waited 20 minutes and screwed everything together. It would be better to use an automobile silicone sealant, for example, Abro Blue, because the construction silicone dries for 3 days ;-(. Collected - does not leak. I began to make bread, and then the following became clear. If during assembly the OUTS on the housing of the mixer drive of the bread vat with SLOTS on the housing of the mixer drive of the bread machine

, the axis of the drive, not secured by the retaining ring, will fall down to the height of the grooves and the mixer will begin to mix aluminum shavings into the dough, nibbling the bottom of the vat. So I pretty much spoiled one of the vats, but I had a second one, and when I understood the essence of the problem and put everything together as expected, the problem disappeared.The modernized unit has been operating for 3 months already, let's see what happens next.
By the way, the fluoroplastic bearing-oil seal supplied by my late father to the "Belka" washing machine has been in service for 42 years.

In pursuit: if anyone does not understand something - write, how I can help. The drawing with the dimensions did not fill in - the models are all different.

DiverHunter Cool! Here is another repair option, in addition to the existing one https://Mcooker-enn.tomathouse.com/index.php@option=com_smf&topic=36855.0

sazalexter, I read this report, as well as everything that is published here about the repair of Mulinech cars. All of these options are weak in one thing: they leave a serious element of insecurity - retaining rings made of "rust"inevitably corrosive in humid hot environments. Well, again, grease - in my version, there is no need for it.

DiverHunter Agree, Moulinex in new buckets changed the design of the mixer, making a Teflon sleeve? It will be necessary to study how the node is made in Panasonic, which has been working for years, there is data for more than 6 years!

- but did not remove retaining rings ! And from time to time I pull out the agitator shaft, wash the bearing stuffing box from the dirt that appears there and put it back in.

Taking off my hat!
My husband can edit the film and put the sound on, he can sort out the car "on his knee", but THIS .....
Can you repeat this design once again for the interested moulinex users?
DiverHunter
Well Duc, don't bast with cabbage soup
Tosha, since your spouse can do what you printed, he could do that, I assure you.
As for "repeating the design" (that is, making exactly the same vat to order, as far as I understand) - no, because there is a lot of fuss. I took on this work because I did not see an acceptable way out, as I said at the beginning of the article. I will help with advice, with a drawing - too, if such a need arises.
By the way, the chan is still working. The end of August will be a year. I forgot to mention one more thing - between the vat agitator axis and the drive, which can be seen in the bread machine, I put a medium-sized nut, because the agitator axle, devoid of a retaining ring, still fell down and the agitator gnawed the vat. I just put the nut on the agitator drive - it has been working since the beginning of winter, everything is fine.

I’ll buy a second bucket, and I’ll give the first one to my dear one (if I can) to tear

Well, dear bakers, one year and one month has passed since the launch of my modernized bread vat. The stirrer shaft began to rotate very easily, but no leakage occurred. The design turned out to be tenacious, you can safely repeat.
Yours sincerely, DiverHunter

Simple and cheap.
The MOULINEX bucket began to leak after three years. I bought the stove for 3200, and for a bucket we, in Vladivostok, requested 1500.
I had to reflect.
I took out the rod on which the spatula is put on. I cleaned it and wound 2-3 layers of FUM tape. He smeared it with vegetable oil and put it in place in a circular motion. After baking, 1-2-3 times this manipulation has to be repeated.
This tape based on fluoroplastic, like the coating of the bucket, does not come into contact with bread. It is sold in plumbing departments for sealing threaded connections. It is more practical to take the one that is wider and slightly thicker. It says: 100% PTFE 19mmX15mX0 20mm.
I learned a lot of useful things on this forum, thanks to the forum users.
I would be glad if my advice would help someone.

Vladik52 I immediately saw the option to use Polyethylene terephthalate (Teflon) capacitors, for example K73-11 🔗 disassembling the case and unwinding the tape in them Teflon is harder and stronger than the fum tape

Easy repair of a jammed bucket agitator. We put the bucket with the jammed side on the pancake of the electric stove and heat the bucket of the bread machine to the operating temperature (well, or until the reddening begins). We remove, using protective equipment so as not to burn ourselves and turn the mixer manually. The principle is used: "They knock out a wedge with a wedge"

We will make you orders for modernization! As soon as the bucket is leaky I will find you for this.

Install ordinary needle bearings of the NK081412, NK081414, 942/8, NK101412, NK101414 series and you will forget about this problem. For the seventh year now, everything works for me with daily baking without problems. There is no backlash at all and the oil seal is not produced. Lubricated with Teflon last time two years ago. By the way, the drive of the pulley from the engine also had to be remade for needle bearings - there is the same problem - the bushing and the shaft are eating out. I had to sharpen a new shaft under the bearing NK121818. It has been working for two years without any problems. There is no backlash at all. In general, with the help of needle bearings, I managed to achieve long-term reliable operation of the bread machine.
