My April 45 MB had machine screws with captive nuts in an ACM2 tub.

Re: Terminal Board Mounting Screws
Thanks Chuck and GSS. Chuck, that proably gives strength to me changing what is on 11730 at present (going to look for the right screws in the left over screw box!!!).
Seems MB might have used a machine screw, GPW a sheet metal?
I have seen GPW's with pan head sheet metal screws into captive nuts on ACM2 tubs too for some clips on the firewall, but not enough to say it was a definite.

Re: Terminal Board Mounting Screws
Ian,
This 3-43 AMC1 MB had the round heads w nuts & lock washers for the 6 post terminal board.It had to be installed before the cardboard firewall insulation. 10-24x3/4 with nuts & washers ...before the AMC2 went to the captives I assume..firewall 2 post terminal board was mounted w studs.

Re: Terminal Board Mounting Screws
Thanks Ralph! Another bit of info to span the ages of jeep production and strengthen what should or shouldn't be fitted!
Anyone else care to add/share what is on their jeep (even if you think it is incorrect as the original poster/original messages in this thread though ooh so many years ago!!!- no offence meant/intended by that comment).
Cheers,
Ian.

Re: Terminal Board Mounting Screws
At least in the beginning, Ford used a grey material for the insulation on the six-post and Willys used a red material....asbestos, whatever....that tells me that they were installed by Ford on Ford made tubs. When Ford began using ACM tubs....THAT is when we need to see what each company used not only for hardware but for the plate itself I think, Then, was there a difference between ACM 1 and ACM 2 tubs in terms of how these were mounted? (Holes or captive nuts or ???)

Re: Terminal Board Mounting Screws
Iowa,
Do you know which Ford plant assembled your GPW?
Tom W. has told me my GPW is a Louisville Ky one. It has its frame
Sn# stamped on the drivers side engine mount. I know Ford didn't necessarily
ship and install the engines the Sn# came from in consecutive order, but just
For fun, mine is 30337, dod 6/1/42, script, rear panel USA 2015846.
I'll check my firewall to see how the 6 post jct block is mounted.
Regards, Dave Neale

Re: Terminal Board Mounting Screws
My 43 Ford tub has pan head slotted sheet metal screws holding the 6 post junction block in place. The firewall holes are totally original and there is no way that a No.10 machine screw will pass through the hole (I've tried!). The screws are 3/4" long.
It makes sense to use them in this location if the junction block was installed after the firewall padding.

Re: Terminal Board Mounting Screws
Chuck, you know better... not asbestos, but a type of phenolic sheet. That material process has been around since the mid 1800s.
MB and GPW used machine screws and nuts from the factory on both junction blocks. I have MB BOM stating so and here is the information on the GPW.
TM 10-1348 Changes 1 April 10 1942
GRW parts and price list, page 61
Available on JeepDraw http://jeepdraw.com/images/jeepdraw/ADO ... -Price.pdf
If anyone has documentation to the contrary I would love to see it. That means some type of deviation report stating the machine screws were not available and sheet metal screws were substituted.
Holes and fasteners may appear original but after so many years anything can happen.
Forgot,,, in the SNL-G503 January 15, 1944 this is in in Section 0606E pages 99 to 102.

Re: Terminal Board Mounting Screws
Mark,
Thanks for the information. I've been back outside and had another look at the firewall and I'm going to have to differ with you on this one!
The two holes for the junction block are completely unadulterated by the passage of 70 odd years, they even retain their rough finish on the drivers side of the firewall. I just tried to get a No.10 machine screw through and it won't fit or even start in the hole. By my reckoning, it's easy to make holes bigger, but bloody difficult to make them smaller!
Just an observation - the holes for the firewall padding are much neater in their finish and accept the original screws quite comfortably, there is little to no metal "swarf" behind them. On the engine bay side, there is virtually no depression to the metal as the holes have been made.
Compare this to the 6 post junction block holes, and I see clear indentations into the firewall where the holes were made, almost like they were just punched through the metal rather than being drilled. They are almost identical to the hole shown by Iowa waaaay back in 2006 where the inside finish is very rough. Of all the factory holes on my firewall, the only ones with a rough interior finish are for the 6 post junction block and the oil gauge line clamp (which ironically, also has a round headed screw!). All of the other holes have very clean cut edges.
Stick with me here...
If there is a requirement for two machine screws, lock washers and nuts to hold each junction block to the firewall, why is the interior finish so rough? You'd really struggle to get all the lock washers and nuts fitted due to the amount of swarf behind the hole.
To be clear, I'm not saying anyone else is wrong etc, just how things are on my 43 Ford tub.
Cheers,
Bob

Re: Terminal Board Mounting Screws
I forgot the MB composite tubs used clinch nuts (A-3538 #10-24).
Bob, I am an expert at people telling me what was and was not correct for my MB-NAVY-MZ-1. Turns out my jeep really did have all those weird features and I was right to stick to my guns about certain parts, holes and fasteners.
But, you need to ask yourself why those holes are not the correct size with the correct fasteners? Has your body been worked on... or is it an older reproduction body? The only one you need to satisfy if you are not going to have it judged is yourself...

Re: Terminal Board Mounting Screws
OK...so I checked GPW-17963 with a script FORD tub and the original greyish 6-post is still intact....then I checked a late December '42 FORD tub and found another one of those 6-post screws still in the firewall....
I think it is safe to say that while the manuals say one thing, reality may often be something a little different. When I removed the one in the December tub I took the following pic:
Here is what is found on the dash of GPW-17963:
So to answer Ian's post....you need a pan head sheet-metal screw, I think it was 7/8" long.

Not that it is completly definitive, but I recall Paolo sells a specific pan head sheet metal screw for this GPW application.

Bob...I think this is what Ian found as well.....not anything more than the usual Willys (ACM) vs. Ford (Ford) tub nuances....and the fact that the manuals are not the last word on these things!
