I recently had to remove the controller shaft on my '13 for maintenance. Even though I installed a NOS pawl on the hand brake 50+ years ago, it finally wore out, even though when I use the hand brake I always lift the pawl off the quadrant to prevent wear. It has now been replaced with another NOS pawl. An often overlooked lubrication point for that shaft is a small hole located just over the controller shaft brackets on each side of the frame. These brackets have a square hole on the early cars up to around '25 that is stuffed with felt to retain the oil. The later T's have a round hole, with a smaller piece of felt, but the purpose remains the same. I pulled out the old felts from my controller shaft brackets, and replaced them with new felt, as I observed the old felt had gotten rather hard after 100 years. I cut some 1/8 felt to the appropriate size, and stacked them in place, leaving 1/8" at the top as a reservoir.
I know where you're coming from Larry. I never gave it a thought until I pulled the cross shaft and found the oil holes in the frame/cross shaft mounting brackets. The felts were rock hard and it looked like there weren't even holes in the frame. When replacing the shaft I made 2 thin gaskets out of some old velimoid paper I had to fit on the bracket faces just to make sure the oil went where it was supposed to. I later used a paper hole punch to knock out 2 plugs in some old felt to recover the frame holes.
Yep, the lube charts don't really show where those are, so a lot of folks miss them.

It is shown in the lubrication chart but I bet a lot of folks don't pay any attention the the chart. Oil every 500 miles.
I just read Richards earlier post on the felts, and I can assure you, the information I posted above is correct. I rebuilt a '25 a few years ago, and it has the round felts.
No argument here. Thanks for the update.
