The adjustment procedure is the same and there are springs on the two adjustment bolts. Thereafter, things are very different on the K45.
No speed or torque can be caused by:
1. Bad brushes, or most likely
2. A bad resistor. There are three wires on the resistor. It should read 190 ohms (or there about) across the red and white wires and 95 ohms (or there about) across the black wire and either of the other two.
3. A bad field coil (stator).
4. A bad armature.
A replacement resistor, field core, and armature are extremely difficult to find.
The Service Manual for the K45 and K5A can be found in the files section of WACEM, you just have to sign up to the site:

Look for "K5-A, K45 Original Service Manual"
SOURCE: My Hobart Kitchenaid K45 clicks when under load.
It could be the worm gear has lost a tooth. It could also be tha tthe beater it hitting the side of the bowl and the head needs adjusting up a little bit using the screw on the hinge.

There is a transformer sold for US travelers that should work just fine.

SOURCE: Which is the better mixer of these old models: K5A
Hello ajlina,
All of these are great home use units, all the attachments are interchangeable between these. The difference between these mixers is the K5 is a 5 quart mixer and the K45 is a 4.5 quart mixer. As I own both of them they are great in the kitchen and have the same durability.
Have any more questions please post to this thread and I will be happy to assist. Thank you for using FixYa.
SOURCE: My Kitchenaid K45 mixer only runs at high speed.
I just fixed my 8 yo mixer! Would only work at highest speeds... first took it apart because it was making a terrible noise. Tthrough this site I figured out how to take it apart and replace the grease. Gears were in good shape, but a small nut fell out of the back while I was working on it. Finished putting it back together, found the spot where the nut belonged- holding the metal housing of the motor to the head. I turned it on and all I could get were the two highest speeds so I took the back panel off again and played with the bottom screw- it seems to adjust something on the wire that controls the speed. So take a philips screwdriver and adjust that screw and see if you get all the speeds back.

What everyone is forgetting or they just don't know is that...The K45 introduced by Hobart in 1962 and was replaced in 1978 by the K45SS are two completely different machines. With completely different wiring systems. The K45 is wired together with wire nuts and the K45SS used connectors on the Speed control switch. All of the websites posted above are for the K45SS (Stands for Solid State) The manual for he K45SS is easy to get from Kitchenaid as the mixer electronics did not change from it's introduction in 1978 to 1986 when Hobart sold the Kitchenaid division to Whirlpool. The K45 on the other hand is a product and property of Hobart NOT Whirlpool or the Kitchenaid division of Whirlpool. The K45 Manual ... well I just can't find one! They way wires are routed is totally different in the K45 from the K45SS so the diagram in the K45SS manual does not help. Also the brushes in the K45 were square not camphor-ed like they are in the K45SS so there is no right or wrong way to insert the brushes in a K45. Whereas; in the K45SS there are four ways to insert the brushes in their holder and three of them are wrong. The K45SS brushes go into a completely different brush holder than the K45. The K45SS is the same today in 2012 as it was in 1978. The K45 is the same only from 1962 when Hobart introduced it to 1978 when it was replaced with the new Solid State model. prior to 1962 it was the K4-A model and it was different entirely. So if the people asking for help say their mixer is a K45 we should be asking for clarification as to a K45 or a K45SS.
