A repository for the vaguely interesting, sometimes boring, mostly pretty dull videos I make from time to time. Enjoy :)
Nakamichi CR4E mode cycling
Nak CR4E showing mode cycling after cleaning the 3 mode leaf-switches.
Did this continuously for approx 5-6 cycles until it came to a stop in 'play' mode with the head carriage raised but not fully engaged with the capstans.
Now working properly after nudging the mode motor cam main cog.
Begininning of the dreaded mode-motor dead spot issue?
And look at that yellow patch on the main cog where some dufus has been in and blobbed the wrong grease on to it and subsequently aged/discoloured over time. Some people. Drrrrp

Seems to want to do its slack take-up thing pretty randomly on tape-insertion.

Nakamichi RX202 reluctant to play

It does actually play sometimes and sounds great. But getting it into to play mode in the first place is the tricky bit! Any suggestions?
Sony D6C playback problem part 2

Bit more detail re the problem described in the previous vid. Giving it a slight tap or knock will spur it into life again! Weird.
Sony D6C playback on battery problem. Any ideas?
Просмотров 1245 лет назад
So this otherwise mint D6C cuts out if I apply slight pressure to the battery pack or case. It also cuts out if it's even slightly knocked. I teased the 3 connector prongs out a little more to make a more positive connection with the battery pack. I also cleaned all connectors with contact cleaner but the problem persists. Any ideas?

Replaced the idler tyre (ES Labs) to remedy this non-playing deck. Now fully functional and sounds great!! Happy days!

RX202 Take-up reel sticking. A little encouragement makes it spin... But not for long. :/
Nakamichi RX202 capstan motor needs attention maybe
Просмотров 8075 лет назад
Bought this deck cheap due to its current issue. It sounds like the capstan motor is struggling and the resistance is causing the autoreverse to kick in. Any ideas? Capstan motor shaft needs lube?
Smoke following Z4 M54 throttle body replacement
Просмотров 5238 лет назад
Switched off engine immediately aftyer first fire-up on replacement of the throttle body. Lots of smoke emanating from the driver side between the block and heat-shield. Suspect the valve gasket has failed. Further inspection warranted.....
This issue is almost certainly the cam/mode motor sticking. The fix is to strip the motor down and clean up the commutator and brushes. there are quite a few videos on YT showing this as this cam motor is used on many different Nakamichi models.
Mine is having similar issue. It will play about once a day then the counter shuts off and no response from any buttons. It's going to a Nakamichi specialist in about two weeks for a diagnosis.
This turned out to be a broken track on the power supply board. Repaired and refreshed by Deb64 (teapeheads.net/stereo2go)
Hello Chris kindly provide me with the manufacturer contact person for the ERS....your assistance will be much appreciated.
Did you ever get this issue resolved. I have one that is doing the same thing. Only difference is that when I hit fast forward or rewind nothing happens. When I hit play, it advances just that tiny bit same as yours.
Did you fix the problem? I have this piece since new in 86 and recently had it serviced. You need a new belt set with idler wheel. Cost 25€ or 30 bucks. Depending on you abilities you can replace it by removing the outside frame and tray. I personally had it Professionally serviced for 224€. Although expensive this piece should last another 30+ years. Good investment since a lot of folks are looking to get one, but there’s only so many available. Could sell it, depending on condition for 400-800€. I recently bought a defective player for a crazy 150€!!!!!! I am planning on either use it for parts or getting it fixed and flipping it. What is with the door? That and the tray are very hard parts to find. Door I have seen for 100€ and the tray, although one clip holder is broken cost 110€. Hope I could help. Finding a Tech to fix this Baby is also a problem. So much to adjust and not everyone is capable. Super piece that’s no longer available but the sound is comparable to a CD!! I have used the Dolby B/C only on recorded tapes and they sound GREAT. But I, like Everyone I have seen turn the Dolby off for normal listening. Otherwise the sound is muffled and sounds like any other cheap player. Good luck.
Sorry for the late reply both. No, it's been languishing on a shelf waiting for myself or a competent tech if I can find one to address the issue. Will post an update if/when it gets resolved. ;)
This the coolest Nak :-)
I would add a tiny amount of Di grease to the contacts.
Lol we are all keeping tabs on you.. ChrisNAK
@@Realrepairtech and you think that's news? The few friends keep me informed but I thank you for the reminder. I use a lot of things out of the ordinary because of experience beyond the norm. Yet I still avoid those toxic chemicals you still use without proper protection. Die electric grease can do much more than most give credit towards and there isn't any chance of accidentally inhaling it.
Hi. I have the same problem with mavic aksium. Did you fix it? Is it possible to centered?
Got it trued. needed a new spoke. all good now.
Relubing is a good idea in general for a deck of this age. But also check the belt before suspecting the motor. Take a voltmeter and see if voltage drops. I'm Zeddie in the TH forums, and I have to fix my RX-202 as well. Following your thread :)
Idler tire probably.
Did you find out what was causing this?
Valve cover gasket needed replacing. was leaking oil over the exhaust manifold causing that smoke. Easy fix after replacing the gasket. Documented over on Z4-forum.com
