Another free neutral question
I am trying to adjust my free neutral on my 21 touring. I have a good neutral with the brake lever straight up but when I come to a stop at a light and depress the pedal for neutral it wants to creep. I presume I need to adjust the clutch lever bolt but do I back it off or turn it in ? Also I have read that there should be some free play on the clutch pedal. On mine whether stopped or driving there is no free play. Do I need free play and if so what would I change? Thanks for the help.

Re: Another free neutral question
I believe the bolt /cam adjustment relates to having free neutral with the lever straight up. Since you have that, I'd think that particular adjustment is not the issue. The clutch pedal should have a slight free play when fully released and the lever is all the way forward. Free play is measured at a particular point on the clutch linkage, not the pedal itself. Holding the clutch pedal down about 2" should give free neutral. The clutch pedal should move down about 1 3/4 to 2 " when the lever is pulled halfway back to the straight up position. Holding the pedal in that same position with your foot should hold the car in neutral when the lever is all the way forward. Another possible cause of creep in neutral is a low band that is adjusted too tightly. A third possible issue is oil in the crankcase that is too thick. Thick oil creep will be most noticeable before the engine is warmed up. There are lengthy discussions on the various adjustments in this forum, some with diagrams and illustrations included.

Re: Another free neutral question
If the car is new to you, you might check the following. Disconnect the linkage between the clutch pedal and the shaft and see how much play you have in the pedal. You should be able to pull/push the pedal back/forward 1.5 - 2" If you have any less than that, it may indicate that repairs have been made to the pedal/notch ramps, and the repairer has made the necessary gap narrower than it should be. In my youth, I made such repairs, not knowing that there needed to be clearance, and lost neutral altogether.
If this is not the case, then the other adjustments suggested may help.

Re: Another free neutral question
The multiple disk clutch submerged in oil will have a bit more drag than the clutch in a more modern stick shift car, or an automatic in neutral. With a T, you might still experience some drag when pushing the car on level surface, but if it is in neutral, you should be able to push it without turning the engine, and also be able to crank without moving the car. If that is true with the parking brake lever in the neutral position, but not true when pushing the left pedal half way down, you likely have the link between the pedal and the clutch lever on the transmission, miss adjusted. Follow the instructions above. It is also possible that the hole in the clutch pedal or the link is so worn that you cannot get the proper adjustment. The link can be purchased from the parts suppliers, and the hole on the pedal can be welded and drilled to fit, or the entire pedal replaced with a better one. Some play is OK, but not too much.
