Model T Ford Forum: Forum 2013: 1919 Transmission, reverse band broke???

Working on this for a friend... reverse went out and found a broken yoke on the peddle side of the band... does anyone know the best way to change it? Not a lot of room in there to pull broken one out let alone get new one in there. Will hogs head need removed to do this, or does engine have to be pulled to change it out???
Thanks & God Bless
Rod

Without the removable lugs, I have heard of cases whereby the bands were able to be removed without removing the hogshead, if done just so, but it is very difficult, so I believe the hogshead will have to come off. The hogshead can be removed without pulling the engine, but working with the heavy hogshead in such a tight confined space is very awkward for one person. Just make sure there are no ladies or children around, for you are sure to say some bad words at some point during this procedure. Jim Patrick

Rodney, I would doubt that the band doesn't have a removable ear. Looking carefully you might see that it is removable, and then you can easily take out the old band. If unable to remove it, I've heard of them being cut (as it's useless anyway...) and removed and then, of course, replaced with the removable lug type. Either way, good luck!

Joe has it right! If the band is not one with detachable ears just cut the band and pull it out. If it had a detachable ear you better find the ear that fell of before you do anything else. Of course, if the band snapped entirely you should be able to pull the two pieces out regardless of the type of band you have but you will need a new band with detachable band to get it back in.

Note:

With earlier hogsheads, the clutch pedal shaft must be cut if you wish to install or remove quick change bands without removing the hogshead.

Um, just thinking here, but metal shavings from cutting a band are really not something I would want in the engine/transmission area. And I don't know how you would cut the band and not have a severe risk of leaving some in there. I suggest just taking the hogshead off.

Revision: to my previous post - only applies to removing or installing the low band, not the reverse or brake band.

Rodney - if you end up removing the hogshead to change the reverse band, that would be a good time to cut the clutch pedal shaft and change all three bands to quick change (if that hasn't already been done) before reinstalling the hogshead.

Try cutting the old one with heavy duty snips. When I first started changing bands I installed them from the flywheel end first, now I work from the back to front. While you may distort the replacement band a bit more, you should be able to slide it in from that end. You could leave the band a bit on the loose side as it does not get used that much.

A good pair of Airplane snips will cut the band without leaving any metal shavings

With a 'broken' yoke, first concern is where is the broken part/pieces of the rivets that hold the yoke to that reverse band?

Get that out of the transmission first. Worry is what any loose pieces will do the transmission.

Pull the hogshead, and to be sure the broken band was intact, or be looking for pieces in the sump

Then get a new band, and replace the hogshead.

The broken piece of the yoke was still attached to the threaded rod part of the reverse peddle, got that out without any problems.
In order to take the reverse band out, will I need to cut and remove the brake and low forward bands first? I tried to get ahold of the unbroken end of the band and pull it out the top, but just not enough room in there to pull it with other bands in way.
Would it be a good idea to replace all the bands with the removable ear type???

If this is the first removable by you, IMO, remove the hogshead. That will make the chore less frustrating. Doing the removable of one-piece bands requires the hogshead off.

Experienced ones could cut a band, and pull out of the inspection cover. I haven't tried that ever, the steel is tough to cut with any common tools and no make a mess of cuttings. Removing the hogshead isn't hard, just takes time. Go slow and enjoy the secrets of the Ford :-)

Follow the Ford Manual for removal and install. The Ford Service Manual shows how to.

For the demountable-ear bands, you will have to remove and modify the slow pedal. The shaft goes all the way side to side of the hogshead. A service bulletin shows how to cut the shaft to proper length. That cutting should be done while you have the hogshead off and have easy access with a hacksaw. The only new parts needed are the demountable ear bands, and the later style adjustment screw for the low pedal, that has the hollow end to receive the shorten low pedal shaft.

Have fun, good luck!






Scale shows how much to cut off the low pedal shaft




Under the cover view, ok for adjusting the nuts on the shafts, but little space to work with big tools.


Hogshead off, lots of room, and easy to repair the hogshead too as needed.


Once you do have the demountable ear bands installed, then you can attempt replacing linings with only removable of the cover. :-)

Oops, mistake here:
and the later style adjustment screw for the low pedal, that has the hollow end to receive the shorten low pedal shaft.

The style adj. screw you need is the one with the stubby shaft, that is for the demountable bands.

Those are awesome pictures Dan. Just a small note: once you have your new bands ready and are holding them in place with safety wire - make sure they are as tight as realistically possible - it will make re-installation of the hogshead a lot easier. That way you aren't trying to pry the bands tighter to fit the hogshead, it's a pain enough just getting the clutch fork to slip into place without fighting that too (ask me how I know!).
