Accelerator linkage tool

[jhaase]

I am trying to adjust the throttle to trans linkage in my 54 Ford with 239 V8 & auto trans, the book says to use tool #T54L-77230-A to align the linkage pins. Has anyone used this tool or something else that will work??

Thank You

Is this a tool that you use to insert two holes to align them? If so. just use a metal rod the size of the holes. You have to do something similar with 55 and 56 four bbl cars and I uses a screwdriver that was the right size.. Not familiar with the 54 linkage

First time I attempted to adjust the passing gear link, I grabbed a bunch of Phillips screwdrivers and started inserting them one by one. The third one I inserted was a perfect fit with no slop. Third time's the charm, I guess.

Looking at the service manual, it looks like a small block that you set on the flat part of the intake/linkage & when adjusted right a pin goes into a spare hole in the linkage.

Are you having problem(s) with the TRANS shifting correctly?

I had the engine/trans out for rebuild, I have them back in & want to get all linkages adjusted correctly.

Copy.

The 1954 F/M only used this tool. I searched but found nothing. Later F/M used pins (or screwdriver shanks as mentioned). There is no measurement given that I see in the WSM (specifications). The tool was used as a standard (and made the process much simpler).

The only other thing I can think of would be to set it by fluid pressure. Let me see if there was a TRANS WSM for the 54 model year.

Well, I went down into my COBWEB CORNER ... ... looking for info and found the 1954 FORD SPECIFICATION booklet. No mention of a measurement given.

It seems this practice was possibly limited to the 1951-1954 FM. FORD built these years in a partnership with BW and started to come out of that agreement in 1954. FORD changed many things on the trans series beginning in 1955, including the initial adjustment of the TV ROD.

This adjustment is meant for only if one changes the idle speed on the engine (or component R&R as in your case) and linkage adjustment change there will interfere with the TV (throttle valve) adj. This initial setting is to get the linkages all into the ballpark and and final adjustment(s) are done with a pressure gauge attached. The 1955/ adj procedure is much simpler as in it doesn't require a FORD SPECIAL SERVICE TOOL..

FORD had to have a separate TRANS SHOP MANUAL for the first FM SERIES (1951-1954). The ones I have seen start in 1955.

And don't forget, the 1954 and 1953 manuals are only supplements to the 1952 manual. I also have those.

There is (was) a FORD dedicated TRANS FORUM but it seems to be not very used in recent years. Let me make a post over there and I will link it here for you to follow.

I am seventy-four years of age and still learn something everyday here ...

thank You, I will try that site.

Below is a photo of a 1951 TRANS WSM. There has to be a combined manual of 1951-1954 but I cannot find reference to one. You would need that manual (1954) to be able to set the pressure without that initial adjustment tool I would assume.

The old Ford-Os and Merc-Os had no vacuum modulator so control came from the throttle valve linked into the engine throttle control system. FoMoCo had an index tool to set the upper bell crank to a nominal position and then there was a degree gauge that was set up with the TV valve lever on the transmission. All was set to nominal for a ballpark shift adjustment on new cars.

Theoretically, if nothing was changed in the system, the current settings should work as good as original. From this point, there are adjustments to change shift characteristics that are considered to be either too soft or too harsh. The transmission manual has all of this information for the model of transmission in use. FoMoCo started using water cooled transmissions and the larger medium case units in 1956 so there are differences between different units after this point. The 1954 was the first Y-block so all the linkages changed from the earlier flathead era but the theory of operation is still basically the same on all the small case units. All a person can really do is adjust the TV rod length if characteristics aren't perceived to be correct.

I will run it & see how it shifts,

Thank You all for your help!
