I just bought a 66 f 100, It is a six banger with a standard, 3 speed I assume,
It is stuck in gear, when I push the clutch it turns over(seems the clutch works) I wanted to check the clutch fluid and the only resevior I can find it for the brakes.
Does this thing have a place for clutch fluid? Is mine missing or am I stupid?
Maybe a little bit of all of the above.
any help is appreciated.

The 1966 F100 has clutch rods and linkage... No fluids to mess with!

Silvio, Welcome to FTE!

 

All clutch linkage. Easy to see from under the hood especially with a 6 cyl. Make sure it is all there and hooked up. Have some one push the clutch pedal while you watch the linkage. It isn't uncommon for the nylon bushings to wear out and for the linkage to not operate properly. If all that works, maybe a bad clutch assembly or even a bad transmission that is seized up.

 

yeah, the guy towed the truck to the house in neutral, I ran it through the gears yesterday to check the pattern and it locked into gear and will not move at all. when I push in the clutch you can roll the truck, you cannot roll it when the clutch is not pushed in. I looked under the hood as you suggested and it all seems to be working the pedal bar pushes the clutch plate coming out of the transmission. it looks like it has a rubber boot on the clutch plate thing that is mostly gone. let me know what you think.

Makes me wonder if the the transmission was empty. No gear lube, melted it and basically destroyed the transmission. What you could do is disconnect the shift linkage from the trans and see if you can move the shift levers by hand. These do move easily my hand so they should. If none of this works, then you may have to remove the transmission side cover, the one with the levers and do an inspection. Don't forget to remove the drain plug to drain any fluid before removing the plate. If no fluid comes out, I think you may have found your problem. There is a good chance that it may be stuck and by removing the side cover you can also get a good luck at the gears and internals so you know what you have.

 

I hear ya, I am willing to bet you are not too far off target. Where do you add lube to these transmissions? I also do not see a clutch resevior for clutch fluid. I have seen it where you have to add fluid with the squeeze bottle via a port on the side. I just bought this thing, it was only 1k but I hate to think I toasted the tranny already..

There isn't a clutch fluid reservoir. All linkage. Your foot actually does the work. No need to look for one because you will never find it. Ok, now onto adding transmission lube. You are right about squeezing it in on the side. Best to crawl underneath and take a look. Probably on the right side of the transmission you will find two plugs that you can remove. Most likely right in the middle of the trans case. One about 1/2 way up and the other on the bottom or underside. Remove the one on the bottom to drain any fluid. The one in the middle you fill with gear lube until it is at the bottom edge of the hole. Simple as that. 2 maybe 3 quarts of gear lube will be needed. I am guessing it is 80/90W lube. I could be wrong about the trans plate. Some 3 speeds have the cover on the top of the transmission and not the side. You may have to remove the trans to inspect it.

 

thanks,
If I remember it looks like a plate on the side with 2 bolts I think. sounds like I am going to have to remove the tranny either way. I appreciate your help. I assume a used tranny is cheaper than a rebuild.

Stuck in gear: Try moving the shift linkage at the bottom of the steering column or on the trans by hand. If you can, the problem doesn't lie with the clutch or transmission.

Very common problem, affects all 1965/72 F100/250 2WD's w/a 3 speed M/T =

At the bottom of the steering column under the hood are two manual control selector levers, in each is a rubber bushing and nylon insulator (Fordno1: No nylon bushings until 1973).

The shift rods attach to these levers...then to the trans.

The rubber bushings age crack and/or fall apart. When this occurs the shift lever binds up. Now, you aren't going anywhere.

btw: You cannot "roll" any vehicle with a M/T if it's in gear...that's the way all M/T's work in every car/truck. Depressing the clutch is the only way it can roll freely.

Since manual transmissions do not have Park like an A/T does, if in gear with the engine off, the trans acts like a parking brake.

C5TZ-7343-A .. Rubber Bushing & Insulator Kit-One kit does both levers / Obsolete

Applications: 1965/72 F100/250 2WD w/3 speed M/T & 1965/71 F100 3 speed M/T w/Overdrive.

Bill,
I did not mention the shifter has been moved from the column to the floor. I did not know if it would roll with the clutch depressed if the tranny was toast. I crawled underneath and screwed with the shifter a little, i did not unbolt it and play with the linkage just tried to move it while it was connected, if it moved it did not move much. I will say all the rubber pieces that I can see have seen better days. you guys are awsome for helping me out.
Silvio

 

Those floor-shift conversion units get worn-out and will sometimes engage two gears at once. The transmission will be locked up tight until one of the shifting arms is tapped back into the neutral position.

 

Thanks for the information, Maybe I need a book to figure out where neutral is. I was planning in unhooking it to see if I can move them by hand then I will have an idea where I stand, I planned on marking them so I know where they go.

 

Chilton Book Co has a Repair & Tune-up Guide for Ford Pick-ups 1965-86 (Book # 6913) that you can get thats not too bad. It will help you out with your truck.
You can also get the Ford Service Manual on CD for your truck on Ebay. It's not much more than the cost of the Chiltons but well worth it.
But your best help is from these guys here.

 

This thing has a indy h shifter, I did not realize it was a hurst until I took a look at it. I did not mess with it as I had to entertain my 3 year old this weekend. Do you know where I can find installation instructions for my hurst shifter?
