Picture request - 383 linkage (CV8 or MK1)

Post by Terdu »

Hi all,

My A727 transmission was removed by previous owner, and replaced with a (badly installed) 4 speed. The kick-down/throttle pressure linkage is still installed on the gearbox housing, but the swivel point that was mounted on the intake manifold disappeared. In fact, the entire manifold disappeard with it.

I've sourced a correct intake manifold, and now trying to source the right missing linkage elements. I'm struggling to get a good set of pictures of all the missing bracketry that would be present originally, but I know its crucial to get the right behavior of the transmission.
Could anyone help out with some pictures of the brackets, springs etc? It has to be for a early MK1 with a 4-barrel Carter though, because I think the brackets and linkages are unique for the throttle/carb configuration.

Much obliged, Jasper

Hi Jasper

Does this image help? It is from the 1967 Dodge Dart/Coronet/Charger service manual, available for download here https://www.mymopar.com/downloads/servi ... Manual.zip

Best wishes,
Nigel

Most definitely helpful. Just not sure about the routing/use of the throttle cable in this case for a LHD car.. I'm pretty sure there's no lever from the throttle pedal to the carb, but a cable rather.
If I remember correctly, on RHD cars the cable actually pulls from the front of the vehicle? On the LHD that might be different still though..

Have a look in the Service Bulletins. There is no long pulling cable on cars before 3079. The early Interceptors use a rod and cross-shaft assembly. That's what you need to recreate if you want it to be original. You can look at pictures taken today but that can be deceiving because plenty of bodges have been carried out on the early cars, including conversions to cable and other mods to accommodate gearbox or carb swaps. The long pulling cable does not appear until part-way through D-series production late in 1968. There may be some clues remaining in the modified setup on your B-series, but I think it will hard to recreate the original setup now. You need good pictures of a B-series which has not been modified. Finding close-up pictures of that part of the engine bay will be hard. The Jensen setup obviously will vary between LHD and RHD because the rod comes from a different direction, and the D-series uses an AVS carb, not the AFB which is correct on your B-series, so the linkage parts are going to be a bit different anyway. If you get the B-series Chrysler book, which I suggest would be essential for your purposes, that will show the LHD setup which is what you want (assuming it is illustrated).

C-V8 Mk3 RHD, but I don‘t know how original or correct the set up is:

Hi Richard, thanks again, moving back to The Netherlands next month, can't wait to get my hands on your books that are waiting for me there. Probably can find answers to most of my questions when i'm diving through them, but i'm here stuck in SA by myself without any info, keeping myself entertained.
I agree that looking at other cars can be deceiving, but I have virtually no references at all at the moment. You have referenced the B-series chrysler book previously, but I have struggled to find the book that you are refering to, as there are so many books written about the B/RB motors. Could you help me in the right direction with a picture of the cover or ISBN or something? Or are we talking about a B-series service manual from chrysler?

Also thank you to Felix. I was assuming indeed that the CV8's were much closer to the early MK1's, and looking at Richards feedback and your pictures that seems to be the case. Very helpful as it slowly starts to paint a picture of the setup for me. I'll keep digging, and will try to reach out to other Sincar's out there to see what they have going on.

Sometime back I tried to identify what Chrysler used the similar rod setup to Jensen but I couldn't find it. The ones I did see were all cable connected directly to the carb. I just assumed at that point it was some Jensen invention to allow for RHD.

I have the LHD setup on my vignale (2544). Here's a not so clear photo

I notice my rod is bent which is either due to adjustment or it's just got bent. I'll have to look at that. I suspect it was bent for adjustment.

It differs from the RHD setup (on 2719) in that for LHD the cable is mounted to the same mount as the rod that goes to the Carb. It seems overly complex.

Have a look at Yearone.com for the B-series book. As originally printed it was a 2 inch thick 8½x11 inch book issued by Mopar and covering all product lines for that year (1966 = B series). Yearone used to be licensed to reprint them. It may be that the same info is now broken down into online sections or it might be available as a DVD. Whether it helps with the Jensen Vignale setup I don't know but it may serve as a guide.

About the same price as the reprints.

The '66 parts manual is actually available there online, great stuff. I found a few hints there. It looks like the chevy's had a short pull cable configuration, which would have been replicated especially for LHD vehicles. It also looks very similar to Paul's photo, and would work hand in hand with the original bracket for the throttle cable/kick-down linkage.

Key would be to figure out exactly how the throttle pedal linkage to the throttle cable is supposed to look like. Guaranteed that would have been a custom Jensen item, as Chrysler uses a roller-style pivot system, as high lighted below. So Jensen's throttle pedal would be different, and probably diffrent for a LHD vs. RHD, as it wouldnt need the 'cross linkage' from RH-to-LH-side.

We're getting somewhere. I obtained a picture from a LHD Sincar, and another Vignale, and the pictures are quite clear. This is really an unnecesarily complicated system, but I like a challenge.

I think the linkage frame/design is shared with the CV8's, and RHD vignales/early MK1's. For the LHD cars, they just used the exact same setup, just with a single bracket on one side.
I'm still trying to figure out: The cable is going to the pedal assembly, and the rod goes to the carubretor?

Hi all, based on the pictures from the LHD early MK1's, its clear that Jensen basically used the exact same configuration of the early RHD's, and just modified the plate/bracket on the linkage somewhat.
Does anyone have any leads on where I would be able for find these unusual parts? I've marked the missing components in red on the picture below. I'll have to modify some of it for a LHD, but that's all good I think.
