I just finished assembling a transmission. Should I adjust some clearance in the clutch fingers before I install it?
In other words, should there be clearance right now? Thank you.
Joe

Joe, adjust the fingers evenly until the spring is compressed to 2" and install the cotter pins. I don't know what you mean if there should be clearance or not. When the clutch screws are adjusted in the fingers should lift off the driven plate and lock the drums together. You may need to adjust the clutch tighter or looser once the transmission is in the car so it shifts smoothly without slipping.

A good starting point is what is printed in the Service Manual. The presumption is that you have a fresh spring and clutch plates, etc. However, after you set it per the Service Manual, you can always adjust it again once the transmission is in the car.

The 2 inches if for checking the compression strength of the spring, at 2 inches the spring should be at least 90lbs or better compressed to that length.
As Bob said in the link to the earlier posting;
paragraph 315 Ford Service --Adjust the three clutch finger screws until there is a clearance of 13/16" between lower side of clutch shift and drive plate shaft flange (see fig. 206) If you don't have the MOdel T Ford Service, the book is some of the best money you'll ever spend on a T.

After the transmission is assembled, this can be done on the bench, set the finger to the 13/16. After it's in the car and it's been run adjust if needed. Because there is only one slot in the screw there is a little lee way. By setting to the 13/16 in the first place you make sure that all three fingers are set to the same approx distance to start with. You are setting the distance with the clutch engaged with full pressure on the fingers and pins.

When adjusting in the car turn each finger screw the same amount, do not be tempted to turn one a full turn and the next a half turn.
