Datsun-240z Vs Fairlady-z432

Recommended Posts

@kats Yes, I am mechanical designer but as a technologist, not a P. Eng., mainly in the mineral recovery area of the mining sector.  Also a Van Halen fan in my teens during the pre Sammy Hagar era.

 “ pre Sammy Hagar era “ I agreed !

I saw conversations about audio system of 240Z in another thread  , now I would like to post some pictures to distinguish the difference between an early 8 track system and a later 8 track system in Fairlady series . I did similar thing before ( on page 22 ) but , this time I want to show the more unique difference.

A first model of the stereo system is 

Hitachi CST-113ZA , this one is for Z432 and ZL . When Fairlady 240Z series was available in Nov 1971 , the system was taken by Hitachi CST-2000Z . This is for Z432 / 240ZG/ 240ZL . 

 The most biggest difference in looks between this and later CST- 2000Z is , a  window of the face plate .

113ZA has a plain clear window while 2000Z has numbers on the window. 

So you see the orange bar in front of the numbers in 113ZA , see the bar behind the numbers in 2000Z . 

I think the reason of this change would be  cost matter . Or to have more better reading in selecting station . However  I realized the early model has wonderful , but very subtle features in the window . 

You will see the function at night . The early model provide the reflection of the number of selected track on the window. 

This is very subtle but I really like it . 

Later 2000Z can’t have the reflection of the numbers due to its window has white numbers covered most of its area .

Please see the pictures of the early model , Hitachi CST-113ZA  at night operation.

Pictures for the comparison of the CST-113ZA and the 2000Z .

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 !

Hmmm...I'll have to see which one I have.

I liked your post on de-mister hatch glass Kats.  I thought I had a new piece of vertical de-mister glass too.  So I got all my glass pieces out to see if I had the same tags as yours.  Such a surprise to what I had in storage.  I have a collection of clear glass, four pieces, and two of them are new.  Will post pictures.

Oh thanks.  I have been collecting parts for many, many years anticipating my restorations that I am just now getting to.  I was well on my way with 26th when the economy fell apart in 2008 and everything went into storage.  Now I'm back on track and spending time organizing my parts stash.  26th is on a rotisserie and I'm expecting her green before the end of the summer.  Just now starting to take 27th apart.  As I restore components for 26th, I'm pulling parts off 27th to restore at the same time.  Just finished two perfect radiators from my collection of three.  Will start posting pictures soon.

Just in time for Mike's new Build topic in the forums!  Looking forward to your progress pics.

What do I do?  Set up a 26th-Z thread on the build topic?

Chris , how did you obtain your 8 track stereo for Fairlady Z series ? Have you owned a Fairlady ? It must be Very hard to find one in the US . Even in Japan , a working condition player is very difficult.

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.

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 .

Here is two sets of race option camshaft adjustable sprocket I have got recently. 

I see the difference of shape of numbers between the two . The one set has eleven holes , this can be set -15 to +15 . But this one has numbers up to - 12 to +12 . 

And the other set has seven holes for E (exhaust)  , nine holes for I ( intake ) . I see this intake sprocket definitely was added extra holes by someone later for better timing  . Exhaust one looks original . 

@HS30-H Alan , could you give me an authentication which set is original, or none of them original ?

Hi Kats,

They both look 'period correct' to me, but I find it's often hard to give 100% positive identification on such parts because they tended to supersede the design quite quickly and there could be several versions. Added to which - as you have noted - privateer users tended to have their own theories and experience, and would modify to their own specifications. And then there were copies, and copies of copies. Yours look trustworthy and correct to me.

As a reference point, here's a photo of some genuine Works team S20 cam sprockets which were used in period. Complicated!
