Qué necesitas

Antes de hacer nada, asegúrate de que la batidora no está enchufada. A continuación, retira la tapa del accesorio de alta velocidad. Si no tiene esta tapa, los accesorios de baja velocidad no funcionarán de todos modos, ya que la tapa engrana el embrague cuando está enganchada.
-
-
-
A continuación, desatornilla los tres tornillos que sujetan el puerto de acoplamiento de alta velocidad. Una vez retirados, el puerto de acoplamiento se levanta libremente.
-
A continuación, retira la tapa de plástico del otro orificio para accesorios situado en la parte superior de la batidora.
-
-
-
-
A continuación, levanta la tapa de la caja de cambios hacia la parte delantera de la hormigonera.

Maravíllate ante las décadas de ingredientes almacenados de forma segura en el interior de su batidora.
-
-
-
En este punto, puedes retirar la correa que acciona la caja de cambios; si se ha desgastado, sólo funcionará el accesorio de alta velocidad. Se quitará fácilmente con un destornillador.
-
A continuación, hay que agarrar el engranaje grande y retirar el "perro" que tiene encima.
-
Tendrás que mantener el engranaje en su sitio (bien colocando un accesorio y encajando un trozo de madera entre el engranaje y el cuerpo de la máquina, bien haciendo que otra persona lo sujete con fuerza) y girar el tornillo con una llave inglesa.
-
Al final, tú o la persona que lo sujeta notaréis que se suelta y podréis desenroscar la última vuelta con cuidado para que el muelle no salga volando.
-
Si se utiliza madera para lo anterior, un trozo de madera de unos 120 mm de largo (y 15 mm de ancho x 10 mm de alto) se utilizó con éxito para esto. Se puede utilizar para volver a colocar el perro calzándolo en el lado opuesto cuando se vuelva a colocar.

Disculpas por los errores de continuidad torta / cinturón en este conjunto - algunos se toman durante el reensamblaje
Hey Josh
Is there a pin or something between the lid and the dog? I can't get the %#*@ thing to engage!
Rebecca - the liquidiser outlet cover has a pin which should push down on the clutch dog to make it engage. If the clutch dog has worn prongs or a stripped thread it may need to be replaced.

Si sólo necesitas quitar el engranaje grande, éste es el momento de hacerlo. Puede levantarlo con un par de alicates por debajo. Ten en cuenta que está unido a un engranaje de plástico dentro de la caja de engranajes y este es el punto de fallo habitual si su accesorio de baja velocidad no funciona pero su batidora funciona.
-
A continuación, afloja los tornillos que sujetan la caja de engranajes al cuerpo de la mezcladora. Hay uno a cada lado de la batidora (sólo se muestra uno). Si tu motor está muerto, puede que no necesites hacer esto.
I'm trying to reassemble my gearbox after regreasing, but can't get the clutch dog back on..any advice? I have the same type as in this picture, not the nylon large pulley. I'm pressing down on the dog while turning the beater fixing, but it just won't catch the threads. Is there another technique?
Silly question, I know, but are you turning it the correct direction? From the pics it does look like a normal RH thread.
On my a701a there are 4 machine screwss holding the gearbox on to the body. 2 at the top with nuts and 2 lower down without nuts. The lower ones only have to be loosened, as (on mine) the gerabox lifts off them.
The large gear/drive dog assembly is different. Holding the gear does not enable removal of the dog, one has to lock the gearbox some other way

A continuación, retira la cubierta de plástico de la parte inferior de la caja de cambios. En este punto, las viejas migas estarán llegando a todas partes. Está sujeta por cuatro tornillos, que se retiran en la primera imagen. En este punto, también debes retirar la cubierta de plástico de la palanca situada en la parte delantera de la batidora.
-
Ahora tienes acceso a la cubierta de plástico inferior - mejor darle un lavado junto con el fieltro. (imagen 2)

He aquí la belleza de la caja de cambios Kenwood (foto 3). Mejor no lavar esto, pero quita los 6 tornillos para acceder.
Hi Josh Watson, if you come back to this at some point, I would like to know how to pull apart the planetary head - the chrome plate and the big gear visible on the other side - as mine is notchy.
Its an old machine I bought to pull apart, and it runs very noisily. The grease was black and thickened around the main gear teeth, and had spun off the teeth leaving them bare. As a result all teeth are worn. It has an aluminium sacrificial gear, not sure if they went to plastic later? Might have prevented some of the wear.
CheersHeya, I'm planning on adding a full disassembly for this as ours is currently burnt out and I think needing new brushes. I'll try and find out then.
Thanks Josh. I think it should be done early on when the gearbox is still mounted, I found a copy of the service manual via someone's comment somewhere, have to find it again, and they mention Special Tools...but I think you can put something in the front outlet to lock it and undo the nut.
Oh hey, here is the service manual and parts list.
http://www.britishexplorers.com/Kenwood%...Thanks Adrienne - thats really useful! Wish I had that when I put these steps together
Hej! I am right now tryxing to repair an old 701A, but as a total newbie I got stuck at this stage: Gearbox still fixed, clutch dog and parts that belong to it still sitting on top.
I´d appreciate it if someone could help me out with how the next steps look like. My aim is to open the gear and get rid of the old grease, but I have now idea how I could get the dog to move, or seperate the top cover assembly and body assembly (patrs 98, 103) Thanks in advance! @joshwatson -

Una cosa hay que hacer: ¡abrirlo! La tapa se levanta mostrando los engranajes todavía bien lubricados. ¡Punto de fallo normal anillada - quitar esto y reemplazar con uno nuevo para arreglar!
-
El montaje es el proceso inverso al desmontaje de la mezcladora.
We have one of these old beauties and will never part with it. My only question is, if I take the mixer apart and find I need a part or two, where do I get them from? We live near Gosford NSW. Any ideas will be greatly appreciated. Thank you.
Try someone like this although they are in Vic
https://elliselectricals.com.au/product-...These instructions are also applicable (near enough) to the KM331 model.
Thanks for sharing!Just in case the repair grease is not available locally (nationally), here’s a good alternative:
> Super Lube 71150 Synthetic Grease PTFE Extreme Pressure High Temperature
It is food safe (NSF H1 registered), hast the same NLGI viscosity rating as the original Shell grease (NLGI grade 2), doesn’t brake down over time and is reasonably priced. Works perfectly fine in my A701A.
Hi Josh,
If there is a dodgy gearbox bearing, do you need pullers of some kind to remove it?removing the dog: virtually impossible by following these instructions. sorry !
You really have to go for it to remove the dog if i recall correctly. Official service manual is linked in a comment a couple of steps above and recommends a specialist tool - the steps there may be better, but I didn't have that when I did this. Let me know if that helps and I can update. Cheers
In my case the shaft holding the dough attachment sheared off while mixing a rye dough that was too dry in hindsight. Instructions to remove and replace this would extend the help if possible.
The part that fell out on mine while kneading dough is the planetary shaft. A piece of a plastic gear subsequently fell out too. Some further instructions to get access to the insides would be helpful. Nothing seems to move at this point.

Hi I get a slight screeching noise between speed Two and three do you think this is anything to worry about.
The mixer seems perfect at maximum speed.
D MORRIS.
Hi,
I’m not entirely sure, but it sounds like the gearbox (or another part of the drive) may need greasing? The grease can dry up over time and it would lead to that.
Thanks,
Josh
what kind of oil do you use in the gearbox
What type of grease is used in the gearbox (my earlier question was an error)
I’m not sure on the exact spec for the grease, but make sure you get Food Grade grease - it isn’t a sealed unit. Googling Kenwood Food Grade grease finds a few sellers - I can’t remember what I used exactly but it was definitely food grade grease, not kenwood specific though.
Kenwood’s service manual specifies to use 133gr (4 3/4ozs) of Shell L.G.P.1 62814 or Shell L.G.P.1 62819. I was not able to find the specs for this grease. As the separation between the gear box and the food is properly solved I think the use o food grade grease is not mandatory, but I would recommend it anyway. Search for e.g. ‘Food Grade White Lithium EP Grease’. Kenwood Swiss no longer services those machines but the front-desk girl recommended to use just Vaseline - I really doubt about this…
I collected many links to instructionas and spare parts in a youtube playlist: https://www.youtube.com/playlist?list=PL...
There is a variety of kits available that contain grease and other spare parts you might need to repair your Kenwood. It might be a good idea to replace at the same time brushes, resistors and capacitors of the motor.
The service manual recommends to press the grease after reassemly into the gearbox one youtube guy just used a scraper to fill the box before assembly.
Walter, Thanks for adding the service manual spec.
I’d definitely make sure to use food grade grease as the gearbox seal isn’t necessarily perfect. The gearbox on my machine above is full of cake crumbs from over the decades. Also, If you use the anything too viscous it will find its way into the mixing bowl.
Our Kenwood just came to a halt! I have dismantled as you suggest and it appears that the gearbox is OK but the orbital crank pinion has lost a couple of teeth.
It seems to turn ok now but will it do permanent damage if I do not get another pinion?

Hi, I have absolutely no power or noise from my A701. I’ve checked the plug fuse. Any ideas?
Hi, mine has done the same - it might be the bushes? I don’t know for sure; we replaced ours. However; it’s up the loft, so if lockdown carries on for much longer, expect a bush replacement guide :)
my planet hub model a701a does not turn when loaded under heavy bread stirring conditions. the drive shaft turns as both low speeds (upper and front) work correctly but the spin loosens the planet nut. the actual problem is the inside f the planet hub hole has been worn larger so that the hub does not engage the flat of the shaft. any ideas where one could get a replacement hub or complete assembly, thanks. enjoyed the vid.
My Kenwood Chef Classic fell off counter but carried on mixing. Cover is slightly scew and beaters dont touch bottom of bowl. Is this easy to fix? Still works.No funny sounds.
Hi, I’m not sure which model I have, but she has a dark blue top. My dough was very stiff, and she now makes a bad noise, kind of ticking. Dough hook still spins. Which part do u think I broke? And how do I work out which model she is please?
Hi
I have an kenwood A701A vintage mixer, it is still working but has an electrical burning smell, any ideas what might be wrong
it probably needs a service does anyone do this? For this kenwood mixer

This was an excellent summary of the steps involved. I have now re-greased the gearbox and it is a lot quieter. Could I suggest one change to the steps involved? It concerns step 5; Removing the dog nut with a spanner. The suggestion is to get another person to hold the K-Beater attachment part still whilst unscrewing the dog nut. This I found impossible due to the gearing which makes it impossible to hold the K-beater attachment part still!! I found using a piece of dressed timber about 120 mm long (and 15 mm wide x 10 mm high) and placing it between the K-beater attachment part and the frame of the machine, easily allowed the dog nut to be undone. Replacement was simply putting the timber the other side to enable tightening up. (Not over tight mind). Great set of instructions. Thankyou.
Thanks for that tip John - I’ve added it to the guide!
Thank you so much for this.
Good day. My kenwood chef A701A. When working with mixer my machine works only if I open it. When I push mixer down into the bowl it does not work. Open and lift it works again. Down dead. 🤦🏼♀️
