changing bands

[RichardG]

SCOTT ,YOUR PICTURES OF WHAT IS NEEDED TO BE DONE CONFUSE ME, MY OLD EYES CANT MAKE OUT TH AMOUNT NEEDED TO BE TAKEN OFF THE PEDAL SHAFT, AND DO I NEED TO FIND THE ADJUSTING BOLT WITH HOLLOW END AS WELL? CAN I MODIFY IT? SORRY TO BE SO THICK. WHAT IS SO DIFFERENT IN THE BAND ENDS THAT REQUIRE THIS MODIFACATION ,

based on your comments I am wondering if your pedal isn't already made for replaceable bands.

Here's the deal...originally the low pedal shaft was so long, it reached all the way across the band and fit into a hollow adjustment bolt on the right side. It was so long, you could not even get the band spring off without major surgery to the hog's head/pedal

The hog's head set up for removable bands had a pedal shaft which went through the band ear and extended a little more to hold the left side of the spring...additionally, the right hand adjustment bolt that had previously been drilled to support the longer shaft is now machined with a protrusion that goes through the right hand band ear and sticks out further to capture the spring...all this means to say that there is no solid shaft going through the band anymore...it is simply supported on the ends.

Courtesy of Lang's Old Car Parts pictures, your adjustment screw on right side of the hog's head should look like this:

And what you want, looks like this:

Once you're holding the new shaft in your hand, you can use THAT part to see how short to cut the pedal shaft to have the same amount of "stick out" to capture the band and spring.

The Service Manual at paragraph #543 says to leave about 7/8" of an inch of the long low pedal shaft, at the shoulder.

There is little difference of bands, other that the demountable ones have the left side lug that is removable.

Since the earlier low pedal shaft runs all the way across both lugs, into the p/n3419 hollow adj. screw, there is no way to pull out the removable lug as it is still captured by the long low pedal shaft.

Cut off the low pedal shaft, and then use the new p/n3419B 'stubby' adj. screw that only reaches to the right hand lug. The left hand removable lug will ride on the now cut off low pedal shaft, with the band spring between the stub ends.

Bold type for your eyes , you're welcome.

And, if you don't have the new style stubby adj. screw, one can be made by threading an earlier hollow 3419, and placing a cut off threaded shank of a bolt, threaded into with LocTite, so that hollow screw becomes a stubby screw.

now it makes sense, the engine im working on was set up for a power unit, and the pedals were removed and plugs were pushed in the pedal holes, why any one would do that , i would think having the feature of hi--lo--drive would be a great advantage,so every thing was missing within, my good friend BILL HARPER gave me a good hogs head, i got the good used bands from Scott, just now getting around to put things together, when i thought about it i remember something about those shafts, thank you very much,now i can attack this job like a pro. KEEP FORDING ON ,FIRST WORLD WAR BATTLE CRY.
