How can I find the throttle friction disks and spring for a 1956 F-40? October 21, 2016.
The throttle friction disc is part number 180713M2, and AGCO/MF sells it for around $3.91
The spring that exerts pressure on the disc is part number 180689M1, and it is no longer available from AGCO/MF. I have a replacement version if you need one.
There are two other springs in the linkage, the upper spring is the compensator spring, part number 181535M1, and AGCO/MF sells it for around $8.50
The other spring is on the lower end of the linkage around the plunger assembly, and it is part number 180088M1, and AGCO/MF sells it for around $23.50.
Those AGCO/MF parts are all available from Jack’s Small Engines.
