Working my way through carburetor linkage install and adjustment in TM9-8012 paragraph 130 on page 156, can anyone tell me the correct length of the throttle rod 7375111 (WO-A-1273), ORD9 page 65 Item E and page 88?

Mine is 7-3/4 inches and it looks to be at least 1/2 inch short after adjusting it all the way out to max length. Except for the piece where the pedal return spring hooks on, it looks original to me but could have been modified (cut) as the truck had a solex carb on it. With it at max length, the idle adjusting screw on the YS-637 carb rests nowhere near it's stop so it would have no function at all if I hook it up this way. Appreciate the comments and advice.

Hi Ron,
Mine is 7-3/4" overall length as well. I do have a WO carb
instead of the military job. I have about 1/4" threads beyond
the nut.

You might look at the linkage back towards the pedal
for some misadjustments.

Take care ,

Mine also measures 7 3/4". I have the military carb and it works just fine. It must be somewhere else.

Gentlemen,
Thank you!. I will check the rest of the linkage down to the pedal. Was just looking for some confidence in that rod being correct on my way there.

Ron,
I've got about 3-3/8" between the back of the nut and the main
face of the firewall, and 2-1/4" from the upper back edge
of the pedal to the floor.

Ron,

You have the wrong throttle rod bellcrank bolted to the rear of the block. Yours is not the correct 7375069 shaft & rod assembly. The upper bellcrank rod should hold your 7375111 (WO-A-1273) rod parallel and even with the middle of the left side of the cylinder head.




Item T is not correct on your engine.

I noticed his spring is not connected. I've had funny stuff happen
if I didn't have a spring pulling tension on some linkages.

I was also wondering about that flat plate on the rod
next to the firewall nut...

I think it's pretty obvious someone used that small plate to provide a splice point to extend the rod and as a replacement spring anchor since the bellcrank upper rod end is incorrect for the M38. Since the rod is the right length now he can use it and find a new correct bellcrank or lengthen the top bellcrank rod and bend it so the lateral rod stays level with the head gasket.

Wes,
Could that be an A-1243 MB/GPW early CJ cross shaft and lever?

One supplier shows it for the M38 as well but obviously it is not.

Uncle John has the 7375069 listed for
19 simoleons...

Gentlemen --- thank you! It always amazes me that you can get so far out in front of me just from a photograph.

Yes, the pedal return spring wasn't connected in that photo (it can be seen hanging from the carb retainer). Hooking it up just confirmed the problem.

My rod is one continuous length (7-3/4 inch) and that flat piece that hooks the other end of the pedal return spring is threaded into it with locking nuts on the front and back. It looks homemade (but old) to me. The threaded end of the rod goes thru the swivel coupling (at the top of the piece that I have in place of the correct Item T) with no room to spare, just threaded in flush to the backside of it.

I'll be calling John this week.

Thanks again! You're saving me tons of farting around....

Ron,
There is a little gizmo that slips onto the assembly at the firewall end that the return spring hooks into. I bet you can't hook that spring into it right now!

Be sure and get that little guy with the rest of it but it probably all comes together.

My spring and clip were missing and Bubba had a humongously long spring tied in on the other end of the carburetor linkage with the spring mounted in a hole he drilled into the radiator shroud................................................

you could push the gas pedal down with your pinkie.

Brian,
My pedal to the floor is a little less than 1 inch --- something wrong with that --- idle to wide open throttle in less than an inch? Going to cut to the chase and order the correct part....

Thanks!

Yep, think about it. With the pedal further
from the floor the lever is closer to the carb.

The geometry is all wrong.

I found this thread on a search.
I noted in the ORD 9 SNL G-740 Service Parts manual that both the WO A1175 MB/GPW/CJ2A throttle rod is listed, as well as the A1273 mentioned above.
The A1175 is sold by many, but the A1273 is hard to find.
What is the difference between the A1175 and the A1273 - length.?
