F 12 Farmall question

bumblebee · Feb 7, 2015

I am currently trying to bring an F 12 back to life.

A few years ago I purchased a pair of weights for an F 12. They
fasten on each side of the frame rail near the front of the tractor. The weights are shaped like a tombstone and supposedly keep the tractor from rearing up.

Question---Does anyone have a picture of an F 12 with the
weights mounted. Why with all the pictures of F 12's is
there not one showing the weights. Does the large end go to front or back? Perhaps a picture of mine will be the first, would I get a trophy?

Question 2---Does anyone know what the correct travel of the
rod that operates the fuel pump is ie. the max and min length.
This would be measured on outside of block with pump removed.

Thanks for any info you would be willing to share with me.

If I remember right the rod should be 7 to 7&1/8 inch. No idea on the weights as I have never seen them.

The rod movement was quite small on my f 12 something like
3/16 inch. Someone put a drop of weld on the end of the rod to
make it longer. Seems to pump ok.

bumblebee There are 2 type weights! The weights pictured below on the F-12 I call pie shaped.
There is also rectangle one. The pie weights are for tricycle front ends, and the rectangle ones are for wide front end. As the pie weight would hit the front axle when tipped. fuel pump rods seem to ware and the pump will not pump as it should. I have had to build many up to
aprox 7 1/8" to get them to pump good. Some even more depending on the ware on cam and the pump.

I have a couple weights like those I use for weights on my disc in hard ground. They are sure heavy. Stan
