Model T Ford Forum: Forum 2016: High gear engaging oddly.

I am helping some local folks get a T roadster road worthy. It was restored in the late 70's. Runs great but needed a little tinkering. The owners have put the Fun projects kit in the coil box and done alot other stuff. They ask me to help them learn how to drive the little roadster.
As I drove it today and went to high gear I noticed it did not engage smooth, it seemed to slip a bit and shudder the car. Once I pulled the pedal back with my foot just a bit and it engaged kinda hard. It has been in storage for a good while.
I told them let's learn what to do to adjust that linkage underneath or whatever so as not to damage anything.
It has been so long since I did that adjustment I can't remember what I did.
I am not even sure the adjustment is the issue. It could be some wear in the linkage or could something need oiling?

Kinda need some ideas because the owners are going to have me come back by for a while and take care of this and to put a side oil line on it and adjust the brake band and install a transmission filter probably while we are in there.

Mack--You need to be sure the E-brake lever is fully forward--sometimes the rear brake rods are set a bit too long. If no problem there, you can adjust the three clutch screws in, a half turn each,after removing trans cover.I had a similar problem recently--adjusted the rear brake rods to allow FULL forward on the E-brake--it doesn`t take much to keep high gear from not engaging properly--Good luck---Paul

Mack: have you checked the clutch spring it may be a little weak.

Looking at the ford service manual you can adjust the "High Speed" clutch fingers which would give a little more tension on the clutch. When you have the transmission door off the clutch spring is in the back and can bee seen with a flash light look for cracks and deformed parts

Mack, all of the above, plus this. If it is a '25 or earlier engine, the lugs inside the brake drum may be grooved so that the discs 'catch'on the grooves, then engage with a bang. Also the disc drum could be grooved. '26-7s have steel shoes on the lugs. And, since it has set a long time, the discs just may be gummed up and it will come out of it with use.

Turbo or standard discs? My turbos shutter when going into high when engine speed and road speed are not synchronized

I can't answer on turbo disc as I don't know the rebuild history.
I must say,after reading this, I will probably check those brake rods and the 3 clutch screws. It does seem to "hold" alot quicker than mine when you pull back as if not going all the way back to hold the car.
I will say this car is in in good condition, as in it was a low mileage car originally.No rust pits on the underside of fenders and such as that.
