Disabling Free-Wheeling on PD

Recommended Posts

Does anyone have a definitive method for disabling free-wheeling on a '33 PD? Every now and then, the knob on the dash will ever so slightly pull itself back in, and the free wheeling tries to kick in.

 

Thanks!

Push the knob all the way into the dash (freewheel and automatic clutch enabled position), then crawl under the car, loosen the clamp where the cable wire attaches to the transmission, move the lever forward into the lock out position, tighten the clamp on the cable wire.

Or plug / blank off the vac feed line from the manifold.

 

Amend that :( was thinking of the vacuumatic clutch.

Yeah. I blocked off the vac feed to go ahead and get that taken care of.

 

I still need to get under the car, but I am also wondering if I can get a zip tie to hold the freewheeling linkage forward.

Mine has a piece of strap steel with a hole at each end that holds the linkage forward.

Our '33 PD is wired up. I would not trust zip ties as they will break at the wrong time.

 

Speaking of free wheeling anyone got a spare knob? Ours is missing along with the cable.

Ok, so here's an oddity. I (stupidly) left on the parking brake for literally half a block and under 15 mph, and it started smoking. I stopped immediately, checked it out, and it all seemed good, but immediately after, the free wheeling started being on the edge of kicking in. I would pull the knob out as far as possible, but it wouldn't do much to solve the issue.

 

I manually pushed the lever forward on the transmission and temporarily used to zip ties to hold it forward. However, it's still doing it.

 

Any ideas as to what I should look at next?

I had to wire mine up too because the previous owner had made a flat piece of steel with two holes for mounting. The holes elongated and the trans would slip out of gear occasionally with a horrible bang upon acceleration.  Works good for now.

Apparently with my first test (zip ties), I still didn't have the lever far enough forward. I went with Tod's recommended method and was able to get the lever all the way forward. No problems since. Thanks!

I have a trans with a permanently locked out freewheeling bracket,you can always leave cable wired to it ( drill for cable and attach to bracket) this way you can be sure it won't accidentally in gauge
