Nakamichi 480 with Lots of Problems - Part 1

- Nakamichi is reserved for channel milestones so I don't have to work on them much, and for my 1k subscriber project I've chosen an old 480. This is a somewhat newer version of this model from the early 80s, but that doesn't mean it doesn't have a LOT of problems. This one does nothing much and the eject mechanism is broken.
In part one, we're dealing with the backside of the transport. New idler, new shutoff belt, some greasery, and fixing the broken plastic eject clamp.
This unit has too much going on for one video, so I'm making life easy on myself and splitting it into parts. I don't like Nakamichi enough to try to do this all in one long video.
Shutoff belt used: 110mm IC x 0.7mm
Control belt: 130mm IC x 2mm
Idler: 13x20x3mm (Fix Your Audio)
I'm re-using the old capstan belt. It's loose but still usable. Otherwise, use an FRSP9.6 if you need this belt.

Camera gear I use:
Nikon D800, Nikon Z50, iPhone XS Max & 13 Pro Max, DJI Action 3, Autel Evo Nano+, Autel Evo Lite+, DJI Mini 3 Pro - Zábava
***IMPORTANT*** The initial belt used on the mode pulley ended up being too tight and would not allow this deck to go into record mode properly. A 130mm IC 2mm thick belt has fixed this issue. I have updated the video description accordingly.
Thanks for the soldering iron trick. Worked a treat!!
Congratulations on your 1.05 subscribers as of today!🎉
Congratulations on 1000 subs. 👍
G'day fella. Been subs for a while and want to congratulate you on getting to 1K subs
Overmolded plastics are the Achilles heel of all these machines. Regarding your epoxy repairs, I believe they used a Nylon derivative for the overmolding. What you did with the Cyanoacrylate first off would have been sufficient had the mating surfaces been chemically clean, and about 10lbs of clamping force been used during the curing period. There's nothing wrong with the build technique, a little bit of glass fiber in the epoxy helps, as does using one that bonds well to thermoplastics, rather than metallic filled JB Weld. Another little hint on consumer adhesives when structural strength is required; the slower the cure time and greater the cost, the better the bond. If you end up needing to use a Rivnut, I can send you a high strength one that could be installed with an inexpensive Harbor Fright tool. I like your closeup views, nicely focussed, and well exposed.
Thanks! I'm not too worried about it for now. It's been holding for over a week now. Looks like I actually had better epoxy for the job until recently but it ran out.
@@Oklawolf Looking forward to your post-build video, I had a 480 years ago, very capable machine.
I hope to get that video done this week - we'll see how things go. I had other obligations last week so nothing got done. Random off topic question... any experience with the Denon DR-F8 or the other flat twin units? They're starting to tempt me.
@@Oklawolf No direct experience with the F8 but generally speaking, I prefer the sound signature of this era Denon to the newer ones.
Looks like a great restore so far, and congrats on 1K subscribers!
Nakamichi is a status symbol, lots of folk like to showcase their 'status', it's human nature.
Yes, the NAKs are good, but so too are other top-end machines - Revox, and the top ends of Sony/Pioneer too.
I'll check in this video later ..........
Epoxy method won't last long by itself. I finally used a small screw and epoxy on my 580.
I'm busy servicing a 480z (also in silver) and it's my first time working on this type of mechanism..
I know that I will never buy a Nakamichi with this mechanism ever.
Same here. I own a 3-head 482z. I am not impressed at all with their build quality. Too much plastic used. Those horrible orange caps. When it all works it sounds beautiful I must say. But now my door mechanism has failed. Another broken piece of plastic. I won't buy a Nakamichi ever again.
I very much prefer my BX150 to this one. Sankyo transport FTW.
@@Oklawolf UPDATE: I had another look at my 482z. It got me so frustrated that I actually threw it out in the garden and set it on fire. Dumbed the leftovers in the bin. I'm not kidding. 200 dollars down the drain and I don't even care. That transport is such a piece of junk. I did society a big favor today. Love my 2 Denon's, Pioneer and Technics tape decks.
Wait until you see part 2. This thing had some NASTY surprises in the front part of the transport.
