Another difference between 113ZA and 2000Z is the signal seeking function. 2000Z has an auto tuning system . In S30 cars , this system is also familiar with a car for US 240Z up to mid 1971 . 

You see the inside of CST-2000Z ,these are my spares .  Enjoy !

Kats do you have any tips on repairing these? I've got a couple of TM-1081ZB(S) radio's and some of them only move in 1 direction, but don't return and come back the other way. I was looking for a switch to clean. I've sent the housing off for gold plating, so until I get it back I haven't looked at it more, but would love to learn more about refurbishing these radios.

Gav,

See if you can find an electronics / TV repair shop in your area.  I took all my radios and the tape player for inspection years ago.  They are not very common anymore, unfortunately.

Thanks mate, I've actually found a shop like that that deals in antique radios along the central coast of NSW, but it's a bit of a drive out that way. I was hoping to figure it out myself and share the knowledge with the community.

My mum is good friends with someone who used to repair old Television sets and has been doing part time work (he's retired) repairing vintage fuel injection systems for early BMW's that are being restored. I've been meaning to ask him to take a look, but he lives in Melbourne and I'm up in Sydney. So it's a little difficult.

Hi , today I have a lot of things to post here .

Gavin,  I have only one tip which I can tell you about is , a repair of a  8 track cassette operation . Seems nobody would be interested in it, but anyway I will give it a try describing it.

There is a big fly wheel in the middle of the deck . This fly wheel is driven by the rubber band . This is so heavy so that it has a tendency to sit lower gradually in its life . What happened next ? The result is Lowered fly wheel scratches a head  of a tiny stud . This is a cause of slower turning of the fly wheel , and the music ended up “ very slow “ . Also you will hear a dragging noise dusting operations, even worse some decks  can’t turn the fly wheel .

to be continued.

Here is the fly wheel .

You see the scratches made by the stud .

The solution is insert a washer to lift the fly wheel just a little bit .Thickness is the matter , you need to be sure that not to insert a thicker washer which would make impossible to snap a E shape clip at the bottom of the fly wheel’s shaft .

And also shave  the stud to make a gap between the stud and the fly wheel .

WOW that is a big flywheel.  Must be for stability during turns and bumps!

Thanks Blue , I am not good at all about repairing those mechanics. But now I am convinced that I can repair this problem. Currently I have three spares , and two of them have this  issue. I guess this will be a common trouble for everyone.

This is bad condition . Auto tuning is good .

About my spare S20 , the head had an quick inspection at racing shop T- mind .

I am happy that the head is intact and no bent , no need shaving . Also crack was not found in visual check . But of course it needs to be tested with filled water in a pressurized condition.

I have managed to obtain a set of race option camshafts , “8L “ is the name which is described in a  race manual . 8H is a lot exciting at a higher RPM but nothing below 3000 rpm . 

Please see the picture , one has  “48” and the other has “49” on the end of camshaft.

I think this is a marking for making and assembling .
