i have a 1864. there seems to be alot of play in the transmission lever when not running. when the tractor is running seems to be ok when push the pedal the tractor stops. goes forward and backwards ok. i did notice that on the control lever arm the fibre washer part # 923-3055 is not there would this cause alot of play in the lever? tried to tighten the nut up but didnt help . that is when i noticed thefibre washer was not there. thanks for your input
