I replaced the ever getting slower capstan motor in my Yamaha KX690 (same as the KX670, but with additional Dolby-S) some years ago. It has now the universal capstan motor from Pacific Stereo, who can be found on tapeheads forum or ebay. Tapedeck works like a charm again with constant speed.
There are universal motors available for sure. Just not ones I can drive to the local electronics shop and buy for 4 bucks like in the old days. Yes that is what these motors cost, about 4 bucks.
A 12V motor with a pretty common geometry, you can find something suitable in old CDROMs, DVD players you can get for peanuts or even free. Make a simple speed regulator or use the one from this dead motor and your good to go. Not just for those 50$ but for giving back life to a nice equipment instead of scraping it. Otherwise very good work, thanks for sharing.
Oooh gives me memories of me servicing my dads Pioneer deck from 1991, I had the same problem sourcing a new motor i was lucky to find some NOS decks that had the same motors. Including heads and pinchrollers made it like new again, Dave how common is it that the bronze bearing goes bad? The axle where wobbling in the end lol
It can be solder the broken winding. For example twist off a round from the winding and now you can easily roll up the two ends, than can solder. Cut and or band the rest and the motor now serviced.
If anyone were to seriously suggest re-winding that coil they're obviously brain dead considering those motors are a dime a dozen and can be literally found anywhere from Ebay to the Salvation Army.
Maybe this is a stupid suggestion, but can you move one of the other motors in the unit to the capstan position, and then replace that motor with a cheap Chinese motor? Would it matter the quality of the FF or REW motor? If that is the case then you could order a small stock of those motors for cheap and always be able to repair the double or triple motor 3 head machines.
I think that it’s possible to repair almost everything, but it’s a question of being beyond economic repair. IE it’s a right off , because it’s going to cost more to repair than either a replacement or what the customer wants to pay. That’s how car insurance companies work, when the cost of repairs approach a percentage of the value of the vehicle, then they won’t repair it and offer you a cash settlement. The insurance company then sells the vehicle for scrap to recover some of the costs, the salvage company then strips the vehicle and sells the parts.
16:48 guessing from the fact there's 4 minutes of video left, you took the option I'd have tried "just to see if it worked" (i.e. finding the broken ends, cleaning and re-joining them with solder & insulating with epoxy or the proper varnish, which you likely have knowing your skillset and perseverance).
Ohhh, OK I called it wrong haha. Well, it was a long shot since all windings were obviously damaged to some degree and may not have lasted long even if you did successfully try that idea.
@@12voltvids True, looking at the amount of chewiness on the windings that's a distinct possibility too. If the motor were to have a short, then there's a chance it'd damage something upstream of the motor's own PCB? I guess most likely 12v regulator and possibly resultant issues in other areas. Not worth it on someone else's piece.
I don't because I am not in the business. I have robbed a few motors to get other decks working but all the ones I have now are in working decks. If this unit gets abandoned you bet I will bolo41.
Hmm, I've always found Matsushita/National/Panasonic/Technics to be very reliable. Is there a reason the motors in particular would warrant the MatsuSHITa or? Cheers
You never worked in a service center. Changed tons of motors. The spindle motors on CD players and dvd players. They deserved to be called "mat-soo-shit-a' as opposed to "mat-soo-sheeta" your mileage may have varied but I remember changing hundreds of them. Some were very reliable though. Namely the direct drive motors used on turntables, cassette decks and VCRs. Those ones were bulletproof.
@@12voltvids Correct, I'm just an enthusiastic home-gamer/jack-of-all-trades & not seen any great volume of equipment. Mind you, no amount of reliability/quality can account for an errant screwdriver up the back of it, they don't like it up 'em! EDIT- out of interest, what were the main failure modes/symptoms in the CD/DVD spindle motors? Total failure to spin up or incorrect speed? Thanks
@@danmackintosh6325 well that's just it, and it would have taken a fair bit of pressure to break through that plastic. The motor was likely running slow and that is why whoever did this did it.
@@12voltvids I realize you're joking, and not do be pedantic, but I've heard that Japanese speakers pronounce it as "ma-TSOO-sh-ta". I have heard some English speaking persons refer to it that way also. It's a bit like the "Techniques" vs "Technics" thing. For years I would refer to it as the former, but I now believe the latter is the "correct" pronunciation.
I'd try to repair the break in the winding just for the practice- agreed the deck probably isn't worth it, but sometimes someone will bring you a deck, & "it's the first thing I bought with my own money" or "I recorded my dad's dying words on it" or whatever, & that makes it worth way more than $50. but the practice is good. fiddly, but useful.
That's no excuse to dump unless funds into something. I remember back in my service days someone showed up with a console stereo and wanted a total rebuild because it had sentimental value. The boss had no sympathy. Told the customer they shouldn't get attatched to electronics, cars ect. This same guy had put 30,000 into a big racing engine in a 72 Pinto because it was his first car. We refused the work. Several months later he shows up with it again. Another shop had charged him hundreds to rebuild it and refinish the cabinet. He had put 1500 into it and it was still acting up. The shop across the street had closed their doors. He wanted us to get married to the mess that the other shop had started on. It was an old tube console with a b/w tv in it from the 60s. First tv they had owned. (this was the 90s at this time ) again was told toss it. He whined and cried and one of the other guys let it in. The boss showed up and his words were get that piece of shit out of my store. The poor guy had put good money after bad trying to fix something that should never have been started on.
A confusing company symbol. I know it’s Matsushita but looks like a Mitsubishi symbol with the three diamonds. (Different companies) Except Mitsubishi has no lines connecting the diamonds.
"Hmm... speed's off, TH-cam video says you can shove a screwdriver in this hole in the back and turn it to.... nothing's happening, maybe it's not in all the way... *GRUNT*" *pop-f-z-z-z-z-zt* "Oh f***!" Smooth move. A stator from a Lionel train motor? Yeah, I'll rewind that. This motor...no. There are banner ads on some audio forums for capstan motors to start with if they wanted this fixed properly, I probably would, since it's a 3-head dual capstan with a solid metal chassis. (Then again, it's still a cassette deck...)
Go back to trademark school. That is matsushita. Mitsubishi is similar but Mitsubishi is 3 diamonds arranged in a triangle. Matsushita is the triangles with the arrows and a triangle in the middle.
Definitely not worth it, why would you waste time even attempting to rewind that motor. Find one off eBay, or even a similar motor, they are a dime a dozen, no point and not even a rare deck to begin with? Plus for $50 barely even worth fixing the deck.
@@carminedambrosio7 I thought so too but I recently replaced a dodgy motor in a three head Japanese deck with a new Mabuchi and it runs fine. Achieving original 0.035% JIS W&F spec too. Mech has been properly cleaned and lubricated of course. Its the same mech that you can see in 12Voltvids Nakamichi DR-2 repairs. I bought the Mabuchi on eBay and payed about $5 including shipping with Speedpak. It took sometime to arrive from China but not awfully long.
Could be worse. Had a nice AlienWare laptop to repair. Owner gave to me in pieces. Tried to repair himself. Ripped off screen display connector on motherboard while trying to replace screen. Sorry, I pass.
