Model T Ford Forum: Forum 2015: TT throttle arm question
Top of pagePrevious messageNext messageBottom of page Link to this message  By Justin H. - Western PA on Thursday, October 01, 2015 - 10:10 pm:

While getting my steering column ready to install in the TT I found a difference in some throttle arms as shown in the picture. The shorter arm is attached to my column which came from a car with a round mounting flange. The longer yellow arm came from what I believe to have been a TT column with the square mounting flange. Is the length of the throttle arm unique to the TT or the square flange column? Which one is correct for a TT? I don't want to install the wrong one and find that there are clearance issues with the throttle rod.

Since you believe that 3531 lever came off a '26-'27 sq. mount column, then that longer one is likely the 3531B, throttle rod lever for the vaporizer carb.

What are the lengths of each ? I can measure mine for you.

Justin, Dan is right. The late 27 TT's used a ( +/_ 1/4") longer lever for the vaporizer linkage that ran over the engine. This was probably the same in the cars starting in 1926.

The longer lever is slightly over 2 1/8" long and the shorter one is 1 3/4" long. That makes sense about the vaporizer carb. What threw me was that the longer one was mounted in the lower position on the improved column as opposed to up high where the vaporizer levers are mounted.

Correct, that 3531B is longer and mounted upright on the upper part of the throttle rod for the Vaporizor carb.

When all else fails, check the parts book, and go from there!

Burger, it seems that it is clear but if you are around your TT and don't mind looking I would appreciate it.

Larry, I tried to find my parts manual but after putting it where I wouldn't lose it, I can't seem find it.

My "sport truck" runs a Kingston and has the 1 and 3/4" rod.
