round shape knobs and square shape knobs

[Go240Zags]

This old thread is very interesting to me. I have this part in my garage: it is brand new still in the original Nissan plastic bag. No I am not going to sell it either....I think the longer I keep it the more it is worth.

That is until someone decides to reproduce the whole unit probably never going to happen with the limited market.

Heh, the first question that one of my friends asked when I took him for a ride in the Z was "What is supposed to be there next to the choke lever?"

Hi,

Recently I was told an interesting story from my friend,Mr.Yoshida who owns 12/70 Z432 (PS30-00347).He said he bought his Z432 in Sep 1972 from a used car shop(He saw a Skyline GTR too,but the Z won!).

He said he is very sure that the Z432 has got squared knobs already when he saw the car at the shop. He has been a owner of the car since then, he just replaced a choke knob to a new one(squared type) once around 1995.He still has the broken choke knob, that is a squared type.And of course, the throttle knob is squared type and has never been replaced after he bought the car.

So, we found a fact that the squared type exist in 1972 already,this is great.

Maybe Nissan started production of squared knob from around 1972 for 69-71 model while a new console was already equipped in the assembly line.

Nissan would have stored two types of knobs , rounded and squared choke/throttle knobs in their parts department at least mid 1980 or so.

And my guesswork is like this,

Mr.Yoshida saw the Z432 at the shop in Sep 1972, just before he saw the car ,the car 's choke or throttle knob would have been broken.The broken knob(s) should have been rounded type as a 12/70 car.

The used car shop would have had to make it better look console, they would have replaced to new one(s). I think a choke knob is usually easy to brake from daily operation.The original choke knob could have been broken, I guess.The shop would have ordered the choke knob and expected rounded type, but they would have get squared type knob.

Then they would have to buy a squared type throttle knob to much the new squared choke knob.

Hi,

I am trying to organize the pictures of the choke/throttle items.

So far we have got many good pictures from owners here,they are very good ones as good references.Please refer this page also,

http://www.classiczcars.com/forums/showthread.php?t=29554&highlight=hand+throttle

Here they are,

#1 A choke/throttle mechanism which has two same length of slots for levers.

and it has a Bakelite sandwich plate for traveling the throttle lever.

I think this is the earliest.

(240znz's 12/70 HS30,18410-E4101-02? kats's 01/70 PS30,18410-E4201-02?)

(PS30 has only one choke cable for the 3 MIKUNIs!!)

#2 And I think this mechanism is also used for the earliest HLS30? Not only a very few of HLS30s which have the throttle lever, also early HLS30s which were taken the throttle lever by the dealer.

(for HLS30 18410-E4401)

#3 Later, a shorter slot for the throttle lever applied.This mechanism has different lever basement for the throttle. HLS30 cars for the U.S. and some other areas do not even have the throttle lever from the beginning.This is true for Automatic transmission too.

(for S30/HS30 18410-E4103-04? for PS30 18410-E4203-04?)

(for HLS30 18410-E4502,E4601)

(for Automatic S30/HS30/HLS30 18410-E4502)

(there is a part number for Automatic 18410-E4501 from Nov 1969 anyway)

#4 A floor console finisher which has only a symbol of a defroster :angry:And

a symbol of a pair of lights :bulb: :bulb:

There are no "ON" for the defroster/lights.

Both symbols are painted white for S30/PS30 while only for the defroster for HS30/HLS30

Also this finisher has two same length of slots for levers just like the earliest lever mechanism corresponding.

(for S30/PS30 86720-E4100 , for HS30/HLS30 86720-E4600)

(This part does not have any superseded part number)

#4 Not for sure of biginning date, at some point, there is a "mask" for hiding the blank throttle lever added for HS30/HLS30(manual) , S30/HS30/HLS30(auto)

(86728-E4700)

#5 Later, there are letter "ON" for the defroster and lights.

"ON" is painted white only for the defroster is for HS30/HLS30 while all the three "ON" are painted for S30/PS30.

#6 Later, a shorter slot for the throttle lever applied on this finisher just like the later lever mechanism.Of course this finisher has a letter "ON" below the defroster/lights symbols and painting variation is the same described above.

Kats,

This is a picture of the finisher from 27th. It matches your picture 009 except your picture shows square knobs. In the case to 27th, the finisher has a blank plug for the defroster switch. There is no "on" lettering for either switch. Only the defroster symbol was painted white. And, of course, the patina resembling a 45 year old dancer from Ft. Wayne, Indiana is stock. The material which covers the blank slot for the hand throttle is there, although damaged.

Thank you very much Chris,

Yes I forgot mentioning about blank plate(grommet) for the defroster and the parking light.

Thank you Her majesty 27th,yours finisher is the best to describe.And still it is clean shape:classic:

The grommet for the defroster (86722-E4100)

The grommet for the parking light(86721-E4600)

E4100 is oriented for S30s(Japanese) , E4600 is for HLS30s, from this point of view,there would not have been any provision for parking light for HLS30s?

A Nov 1969 HLS30 parts catalog has a mistake , it is numbering opposite each other.We can see many of mistakes like this, choke knob and throttle knob are also numbered opposite. While a Japanese parts catalog is showing correctly for the grommet for the defroster.

I am excited about seeing 27th has a blank mask for the throttle lever.

When it was attached? At a factory in Japan? At a dealer in America? 27th is a extremely low VIN car but it does have it!! A 1970 U.S.240Z brochure has a picture of a finisher,we can see no-mask for the throttle.Just no-lever, no-knob and there is a slot.So, only like these brochure cars(00006/7/8 according Carl mentioned) do not have a mask?

Very interesting,thank you.

Ah, the mystery of old worn out cars! Some of the mask material is on the finisher, but why would it be ripped to show the slot? Strange. I promised myself that I wouldn't take 27th apart until I finish 26th so we will have to wait and see what is below the console. I plan to restore the car with a hand throttle.

[kats]

Chris,

Can you see inside from gaps of the broken mask?

I think 27th has a 18410-E4401 then removed a throttle lever!

kats

[26th-Z]

Ok, I will lift the console and report back. Right now it is very cold in Florida. It was 6 C last night and I hear it is supposed to freeze tonight. I don't think it will freeze at my house, though. I live close to the Gulf.

Hi Kats and Chris,

I'm attaching pictures of the original finisher from HLS30-00032 when I found it, and as it looks now. It looks like the parking lights and defroster symbols were both painted white. Chris, your parking lights symbols looks like they were painted white too, but just more faded.

I mentioned before that my car still had the small plastic grommet in the top of the accelerator pedal and the screw for the cable attachement bracket, so it must have had the throttle originally and been removed by the dealer or at the port. I added a used throttle unit after I got the car.

[mdbrandy]

Here's what was on #215 when I got her. Look's like Mike's original pic. Sorry about the quality - I don't appear to have a better one, and the parts are in boxes in the garage...

[kats]

Thank you Mike,

and Mark , how are you doing? long time to see you again:classic:

Mike, I knew that you are concerning about the painted parking lights, when I saw the picture before and I thought so too.Thank you for reporting about the plastic grommet for the end of cable,that is a good evidence.Where were those removed throttle cables sent? Just in a trash bin and burned? What a sad story:cry:How about steel wheels and hubcaps?

But I am wondering could it be just a result of accumulating dusts looked painted white ? If the symbol of light is white, it would have looked more white would not? If #32 has a painted finisher, it is 86720-E4100.

The difference between 86720-E4100 and 86720-E4600 is the symbol of light is painted white or not, I think. On the really early cars, it could have been happened installing mixed up E4100 and E4600.Nissan Shatai might be panic.

Hi Mark, your car has a throttle lever, great:classic:
