Service Manual Does anyone have a sewrvice manual for this machine? I think I have a gearbox problem. It makes a strange noise when under pressure and it slows down.

The machine needs stripping down as something it likely worn. The gearbox is also packed with grease and may need re-packing. They do need periodic servicing. Does it make the same noise with the bowl removed? Sometimes the noise will be attachments hitting the bowl. There is an adjustment screw underneath to see clearance.

If your N-50 is making a grinding noise there is a strong (almost certain) possibility that the cause is more than just needing more grease.

The sources of the noise are from the transmission case (front portion of the motor housing) and/or the planetary (where the blade attaches).

A search online should turn up the N-50 Service Manual.



With luck, it may be that the two adjustments specified in the Service Manual will do the trick

Three things come to mind regarding the noise:

1) If simply greasing the planetary does not do the trick, then

2) There are two adjustments to the transmission detailed in the Service Manual. And if that is not the cure

3) The transmission housing will need to be removed to find the source of the grinding. This is where the grease is truly encountered.

Try looking at the Service Manual:

Check that the nuts under the back cover at the sides have a bit of nip on them. It could be the armature polling on the fields. DO NOT OVER TIGHTEN THOSE NUTS.

Ring for the customer service number and they will provide you .

Most likely the worm gear in the planetary has shed a tooth. Can be replaced easily by a local repair shop.

I strongly suspect that this is a gear problem.

Hi I'd really appreciate a service manual please?!

It appears that you've got some internal transmission gear issues, and a situation similar to my wife's mixer, which we got new in Dec 2006. It could be as simple as the gears have become loose and are making different contact, hence the noise. The higher the speed, the louder, higher pitched sound you'll get. It may also be indicative of a potential gear failure (after all our increasing noise, the bevel gear broke and the mixer 'froze'). If your mixer is under warranty, contact Kitchenaid. If it's out of warranty, then take it apart and do a diagnostic exam of the gearing. Whatever you find you should be able to fix yourself. Be sure to have the Kitchenaid Part Manual (Part No. 8212278 Rev D) on hand if you attempt to disassemble yourself. It also lists all the parts so that you can determine, which parts, if any have failed. You'd think that the Kitchenaid name would warranty their mixers for a lifetime... So much for quality in America today!
