Adj. Trans Bands
I have a 26 coupe and want to adj the bands. A while ago 4-6 months a fellow told how measure the band adj by using the cams on the outside of the hogshead. Does anyone remember that thread? If so could you please let me know where to find it. Thanks

Re: Adj. Trans Bands
Richard, my rule of thumb for the Kevlar bands I use is to adjust them just enough for them to do the job required, with out slipping. I avoid the temptation to go a little bit further so the adjustment lasts longer, so that I can keep maximum clearance between the bands ans the drum.
There are many reasons why there can be no definitive method of adjustment, given the hiding our 100 year old parts have taken. Some of these are
- worn pedal ramps and notches
- bent pedals
- twisted pedal shafts
- pedals/notches loose on shafts
- worn/damaged band ears
- well worn drums
- weak springs at the ears
- different thickness band material
- etc
If all these issues have been addressed, then adjusting the pedals so they are '1.5" from the floor boards' might work, provided no-one has modified the slots in the boards. Your searched for link to adjusting by the ramps/notches may well also work. But, given the variables, take the ideas on board and work with them, and be prepared to modify them to suit your particular application.
Hope this helps.

Re: Adj. Trans Bands
Adjusting the transmission bands is a trial and error procedure. The Ford service manual and the owners manual don’t give any “exact measurements” to get the correct band adjustment.
What the Service manual does say is don’t adjust the bands to tight so that that continually drag on the drums. If you do that you cause premature wear and heat and quite possibly crack the drums.
They should be left loose and adjusted just enough to get the car to move forward, reverse and brake well and that’s it. Don’t keep tightening the bands “a little more” just in case.
As Allan says there are many variables to consider and the adjustment is not exactly the same for most every T. Hope this helps.
