Picture of my Hitachi D-RV7 auto-reverse cassette deck

Here's a picture of my Hitachi D-RV7 auto-reverse cassette deck, to go with the German manual I just uploaded a few weeks ago.

Also shown is my venerable Sony CDP-55 CD player (made in May '86), an SVHS switch box and my junky DiamondVision DVD player. (more details on the deck below)

The Hitachi still works great, will be needing a capstan belt soon, as it's starting to slip on startup. One issue I had with it recently is during auto-reverse, the head got stuck halfway, and jammed in a sideways position. I had to remove the trasnport to see what was happening. I found a little nylon gear on the flip-over mechanism had cracked in two, and was skipping teeth and getting out of sync. I puzzled over what to do, use it as a single side deck or what. I removed it and glued it, cracked again. So, I glued it in place on the shaft with superglue, held together this time. Still working fine, thought I was a goner that time!.......:^)

Hear some people get this deck and have trouble with the auto-reverse jamming, so is anyone wants some pics or instructions on how I fixed that little gear let me know. Also let me know if you want a pic of the capstan belt routing, as the two flywheels have to rotate in OPPOSITE directions for the auto-reverse to work properly. The belt wraps around the R flywheel but over on top of the left flywheel (not underneath).

Thanks again to HiFiEngine for posting my manual, it always gives me a thrill to see any stuff I upload become available to the world.

Cheers!

Thanks for the note on the capstan routing, the belt on mine had completely disintegrated before I opened it up so I didn't realize they had to spin in different directions. I thought I'd have to live without auto-reverse, but sure enough with the proper routing it functions perfectly now!

Thanks so much for your comment, I appreciate it and I'm so glad my info was helpful to you! If you need a user manual, I found out that one of Realistic's decks is simply a re-brand, and the manual for that has all the info you need. I have not been able to find the original Hitachi manual anywhere; one was supposed to have been included with my deck when I bought it (the seller lost it, groan!....:o). However simply search for Realistic SCT-42 on here and you'll find an equivalent. Congratulations on getting your deck running, nothing beats that feeling when you fix it yourself! Cheers!

Re: Picture of my Hitachi D-RV7 auto-reverse cassette deck

Bellarmine, Could you please supply me a pic of the belt routing. I have my unit apart and ready to clean up the goo. But I don't quite understand how you mean about the routing.
Second question... I see that Marrscommunications.com has a complete set of belts for $24.95. But it looks as though the only one in there besides the main flat drive belt is a small square belt which I think is used for the counter. This counter belt is in good shape. Only the drive belt is disintegrated into goo. OK. Having said that, Marrscommunications.com lists all of the Realistic models for which this belt kit will work. Included are SCT-42 (which is mine) and SCT-10. OK. hold onto that information. SCMelectronics.com is selling a single flat belt which claims to work on the SCT-10. This single belt sells for $6.75. So I'm inclined to go for the latter. Other than price, another reason I lean toward the SCMelectronics belt is that there might be more likelihood of it being made of new material since it was not necessarily an old replacement kit. Also in another forum I'm told that the size of that belt is 9"IC x 3/16"width which agrees with the dimensions of this SCMelectronics belt.
Any thoughts on that?
Also, I hope it's overheating and not just age that causes the drive belt to become goo.

Sure, be glad to help. Just set you a PM. Cheers! Bellarmine

Re: Picture of my Hitachi D-RV7 auto-reverse cassette deck

Bellarmine, This is a followup on all the good help you have given me. I obtained the 10.2" belt from Studio Sound. I have installed it on my Realistic and it works great. When I got it I was a little apprehensive about the width of the belt. The width is 0.125 which is 1/8". Someone else had recommended a 3/16" wide belt. The pulley on the motor has a curvature to it which of course has the purpose of holding the belt in the center. I was concerned that maybe my 1/8" belt would be too narrow to take advantage of that feature. But evidently it's adequate; it works OK. Thanks for your good help.

Re: Picture of my Hitachi D-RV7 auto-reverse cassette deck

Can you recommend that I get that $6.75 belt at SCMelectronics?

Re: Picture of my Hitachi D-RV7 auto-reverse cassette deck

It's funny because I had the opposite issue haha. Mine is a Realistic but I couldn't find info on the belt until I found your comment under the SCT-42 that tipped me off that it was actually a Hitachi. The replacement belt is still in the mail, but a temporary elastic band let me confirm it plays in both directions without jamming now.

Interestingly mine was riddled with electrical issues but they all seem to be fixed now. A few pins on a few of the ICs were ripped out of the board (I have no idea how that happened), but soldering them back with jumper wires fixed my reel motor and peak level meters. My right line in was also dead, but it turned out to be a simple fix (bad solder joint at the connector just needed reflowing).

I wish I could remember where mine came from, I only know it spent years out in my parents' shed until I decided to try to revive it recently. I'm glad I did, didn't realize it was such a nice deck (the Radio Shack branding made me think it was cheap junk at first glance, I never suspected it was a rebranded Hitachi).
