I recently worked on a Pioneer CT-F700. A monster cassette deck. It needed 4 new belts I think plus the rubber on the idler pulleys needed rejuvenated.

Just to add to this; I fixed a Yamaha KX-130 with a similar counter belt problem. The belt snapped and left sticky black goo all over the tiny sensor by the right capstan. The black goo made the deck think the tape was not moving. cleaned it all up with 99% isopropyl and removed the remnants of the belt. All fixed up, runs fine. Interestingly the sensor looks for a bright/dark/bright pattern as the right capstan moves. Thanks for this vid, it put me on the right track re: counter belt.

I would dab some white lithium grease on a qtip and lube all those mechanisms where parts are sliding.. That would quiet some of the moving parts down, as I'm sure the 30yr old grease once there is long gone. Tape decks can be a real PITA. 😅 At least you got it working again. 👍

As for the deck 2 issue : There's a solenoid that is in charge of moving that white gear .In my Yamaha deck tape it was stuck at "on" position because one of its leads touched the other .I had to put a tiny piece of shrink/insulator to make sure they won't touch again and problem solved . My guess is that when you disassembled it - it moved and came back to life .If the issue returns - take a look at that solenoid .

It's a good idea to clean the capstan (that controls the tape speed) and pinch rollers as well, so the tape won't stick to them, and wrinkle. Next up, adjust the tape speed, and align the head azimuth!

@@CDJF1 I'm on the fence about this. With 2 head decks, the head will demagnitize itself when recording due to the high frequency (~100kHz) bias signal passing through it. I've never seen any objective evidence, only "it sounded better after". The rest doesn't really hold a magnetic field for long.

Good job! Those melted belts are a real PITA. I've repaired two dozen or more old decks, cassette, R/R and even 8 tracks. The melted belts are surely the worst thing to see when you pop the top, but nearly always it means the deck is still mechanically sound.

I have a Yamaha KX-1200U and the main drive belt “melted” just like the tape counter belt in your video. I tried everything, except brake cleaner, to clean it and it was a total pain. Wish I had seen your video first. Nicely done!

I've seen belts do that before. I found a couple outlets that sold various size belts in a mixed bag. Some wide and some round. Found them on Ebay. My tape deck from the 70's turned out to be the main drive motor. The shaft was very slow to turn. I should have used a light oil on it but me.. I had to take it apart. Getting those brushes back in place was impossible and now the motor turns but no tourque. So I'm looking for a new motor for my Denon. Good Video. Thanks.

Doesn't brake cleaner dissolve plastic? I think I would use alcohol. And should you maybe use just a tiny amount of white lithium grease on the small gears before you put it all back together? And FYI, on eBay you can buy an assorted pack of 50 cassette deck belts for about $8

Exactly what happened to my 262 Got it at the thrift store and put in a test tape just in case. It came out with the band full of that goo. And counter not working. I opened it and no belt at the counter. Will go in now and clean that up. Goo on the rollers and all. More messy than yours. Thanks for the video.

Clear bright white plastic is often nylon, and will not easily becoming brittle. The older stuff that becomes yellow is often bad. Using solvents is safer if you try some first on a small spot, and observe if it will not take the shine off the plastic. If not, you can soak the wheel for a few minutes, and use a brush. I think I would try white spirit (like terpentine) here.

Hi, thanks for the video. I found a Yamaha kx-w492 and I'm planning to buy it. The owner said it works well but on occasions the tape doesn't start moving. He says that if he hits stop and then play again the problem fixes. I was thinking it could be a belt related issue. Do you think that's what it is? This certainly helps me know where to look! Any advice would be welcomed!

99.9 percent Alcohol will melt the goo effortlessly. Ultrasonic cleaner with 99 alcohol. Watching people struggle cleaning goo is hard for me to watch. I just smashed a casette deck because it would not work properly after 3 days of effort. I have no love for tapes.

+1 on the isopropyl alcohol.. That's safe. Brake cleaner is quite risky, as some of it contains acetone, among other things that'll melt plastics.

So just fill a jar with 99% isopropyl and then put the gooey gears in there then set that in the tank of your ultrasonic cleaner? I have dealt with a few of these and have nightmares cleaning with isopropyl (not sure if I used 99% or not) and q-tips and paper towels by hand. Took me 4 or 5 hours over multiple days to clean the goo from the transport of a Nak CR-3A. But seeing as I got it for $50 and it looks and works excellent now it was a good deal.
