Re: Replacing a belt on the Kenwood KX 1030 Tape Deck
You do have to take the front fascia off the unit to get access to the mechanism mounting screws, to then get the mecha into a position that you can remove the capstan flywheel plate etc to replace the belts and clean drive surfaces. You can get an entire replacement belt kit from here
These decks are well worth repair if you have an interest in cassette decks. Good luck, and thanks for using FixYa. If you need more advice , feel free to ask me :)

If you need a cam motor, they can be found but mounting might have to be modified. The best way to get an answer is to connect with those Technician who used to work for the company in the past. On Tapeheads dot net the user name Nakdoc or Perry would be the best people to deal with in this case. They are both Technicians who could fix it for you as well as get it going in the best of condition.
Recorder fan hi! Check the voltage of your motor and then fit a generic motor to it. Check the belts and lubrication of the shafts of the capstan bush a small drop of sewing machine oil works wonders also check the roller geometry is it round and the tyre touching surface is it flat or is it bulged If bulged replace.
Replace with a capstan belt from Marrs Communications it should be a 16.8" IC belt. Fred know which one if you tell him the model.
The capstan motor can also be worn out. These need to be taken apart and examined at to brush life and to see if it has bee overheated. I get a lot of motors that are burned up by customers.
It is a $150 part.
The mechanism needs to be taken apart sufficient to get to the flywheel and capstan motor- this usually entails taking the metal motor bracket off the back. It is not that difficult once you have done one. I may have replaced 50 to 100 of them at Teac in Chicago. Also oil the capstan bearing when changing a belt.
Since the unit stops it's noise when the capstan shaft is stopped, something I might add that you should never be able to do in a good deck, the noise is most likely coming from the motor not being grounded properly. This will be more a buzz sound than a hum. I am servicing decks these days and am not too expensive but that depends on what you consider expensive. The unit needs a checking out if you are going to use it long term anyway. I am near Chicago if you are interested. E mail- email@example.com
clean the head with alcohol.if the head surface is not smooth,it could be worn
.there is a small screw on the side of the head for changing the azimuth.
most front load tape decks have a small hole in the front of the door, when the outer part of the door is taken off.
the best way to align the heads with with a 10khz alignment tape and an oscilloscope.
the screw is adjusted for maximum high frequency performance.
a qualified shop should be able to do a complete service and align for around 50 dollars
Hi Larry, I have worked on similar units just recently. Three things can be at issue here. 1 is the lubrication of the slide plates of the mechanism, 2 is the belt is loose and this is called a cam belt you can get them from MCM for around a dollar. 3 is a problem I found while working on these decks and that is not that easy to resolve but it can be fixed. I determined in the unit V750 that I was working on that the cam motor made a noise. This motor was taken out to see what was going on and I found that the unit shaft had become sloppy at the rear end where the brushes are due to the front having a brash bearing but the support in the rear was nylon. I then secured with some research a much better motor from an Electronics firm and installed it but it did need new 3mm screws and a little modification of the mounting plate- which can be done with a drill. I mounted this new motor and everything ran perfectly AND the new motor had brass bearings at both sides. Why do I know all this stuff? I am a past Lead Technician in Chicago from Teac corporation and I am still working on deck full time.
capstan belt may be failing. check this by removing lid and touch the capstan flywheel when running. if it is easily stalled/slow to come up to speed and or the belt slipping badly then belt will require replacement.
