Thanks very much, Trevor, for taking the time to share this excellent tutorial. My brother-in-law's CR2A had stopped working and I was having a devil of a time tracking down the problem. It had the same transport issues yours had and after following your steps and cleaning and lubricating the motor and worm gear, it's now working again. Great video.

Thank you SO much, i just performed the cam motor cleaning and relubrication on my nakamichi CR-1A after dealing with it only playing like 2% of the time for over a year. I was worried at first but your excellent footage and clear explanations of what you were doing and really made this repair possible for me. It works like it's brand new, i'm so happy to have my cassette player working again

Thank you so much. I manage to repair my old CR-2 following your video. Great work!

Geez Trevor, I’d never remember all these steps in putting it all back together again!

Wow, you weren’t kidding about it being a big job! Thanks again for the patience and perseverance, it sounds amazing! Better than I ever remember.

Great info thanks. You're very skilled.

Thank a lot, My CR-2E (from 1989) did not start playing, though Fast forward and Rewind did work OK. The lift returned to initial position after 2 tries. Just pushing the contacts a couple of times solved the issue. I only had to pull back the whole block, after releasing the ground connnection. Your video helped a lot and saved it from the scrapyard. Plays wonderful again. THis was my first investment in high-end HiFi

Great tips on motor disassembly/reassembly. Nice work!

Great and informative video. Enjoyed watching it!

You have Skills my man. Enjoyed your presentation.

Excellent photography Trevor, no silly zooming in and out. There's so many little things that can go wrong with old decks - it's often a long chain of one repair/mod after another, but we often do get there!!! I don't know about you, but I can spend 10, 20, 30, 40 hours and more on one deck alone - repair or rebuild can be a process of one step forward, followed by one and a half backwards! ;o) Regards and thanks for the video.

27:27 - I think you certainly know that usually in almost all motors of this type, there are on the outside of this white plastic piece, two holes where a thin wire must be inserted in each one in order to move the brushes away from the center of the shaft, allowing you to install the armature without the collector interfering with the brushes. That's the easy way but I don't know if this motor has those holes. 58:07 - This motor is diferente it has justo one ripped hole that serves to separate the two brushes from the motor. Thanks for the nice video.

見事ですね。できるだけモーター分解はしたくないのですが、特にダブルキャプスタン機はモーター修復は必要ですね。　VANHALEN　のテープもいいですね！！　これからもナカミチを大事にしてください。

Thanks for your wonderful video it helped me immensely to repair mine.😁

Great repair!

Thank. Splendid video. Very well explained.

Great video.

Great video Trevor, thank you. Can you kindly share the part number for the belt, please? I have a CR-2A that needs a new one.

That was very good. (I hope that I can emulate this on my Nakamichi CR-1A) which is currently exhibiting similar symptoms. Thanks again

Thank you for such an informative diy.

What a quality build nakamichi made in those days. I had the one that automatically could turn the cassette. Also transformers build in if there was a new cassette deck made I bet they used switching pcb instead of transformers. Much cheaper but crapy powersupply.

1:04:30 Van Halen!!! :) Pity you didn't show the last test you mentioned. Could you suggest me a grease for plastic gears of dvd-bluray player especially for the bars where the laser head glides and a more viscous for opening mechanism? I guess the former is the same you used for motor shafts and bearings. thank you

Thanks for this extremely informative video! I have a bunch of old Naks that are in various states of disrepair. Where did you get that sliding belt measuring tool? That was cool.

Very nice 👍🏻❤

You can use Superfloss to get the hole of the capstan cleaned

hi...great vid..how do you get direction spindles off to repair motor...?? not a single vid shows replacing that motor. can't figure out what lets them loose

Please bore me with the calibration process, I'd like to see it done for real. Also would like to see the reel motor removal and serviced like the other two. Great video!

Well done! I hope my CR-1E won't need similar Service 🥴

Thanks for this video: I’m about to do the same on a Cassette Deck 2 but I haven’t marked the cam gear position before I’ve tested with low voltage to check if working. How do we know the cam gear position? Only doc I could find was for a BX-2 which I hope is the same for the CD2 but can’t figure out if Cam0 should be the inside or outside mech facing.

Excellent video! I found this video searching for info on this deck. I pick mine up in two days for $100.. Guy says it plays fine but I know what to do in case it doesn't.

Wonderful video! I was wondering how the W&F was with the new belt? I have 2 CR-1s, and one just developed the same problem which brought me here. Thanks for taking the time!

Great video, how much would you charge for this service? I have a nak cr 3a with similar issues

Please tell me nakamichi Cr 7 control Motor is same in nakamichi Bx 100 or 125

Hello Trevor , what kind of lube do you use on those mechanical piedes/shafts............?

Is there a source for new or rebuilt motors? I checked mine out, and one of the brush contacts had fallen off. The control motor that drives the cam is the one that I need to find.

There is a tiny hole at the back of the motors right in the middle of the motor cover. can you lub the back bearing from there?

I don't understand the speed test with the oscilloscope? If I got you right, you fed a 3khz signal to the deck, recorded and replayed it. Then you tuned the speed? But if you fed it a 3khz signal and recorded it on a tape going slightly too fast, wouldn't that still play it back as 3khz? I thought that's why people use commercial tuning tapes where the cassettes tuning signal was recorded on a calibrated deck according to an industry standard. Or am I missing sometihng? I'd be glad if you could clear up my confusion

Where to adjust the speed ? Directly on the engine with a small screwdriver ? I would have liked to see how you proceed on the engine to regulate the speed.

Where can you purchase the belts.

Nice work ! but after all Nakamichi older models have bad elektronics and that Sankyo under level transport , but Nakamichi is most advertised name isn't it ,

At 32:02 you put grease on the worm gear. The container says "HX". What is the brand of grease that you are using here?

what product are you using for lubrication?

I guess one of my decks is suffering this fate. If I had a fraction of your skills and knowledge I could fix it. :(

Looks like heart surgery to me.🙂

You need to have blood test, you have liver spots on hands. Sign of poor diet or too much drink.
