Zetor 3320 bolt to mount loader

Kickinbull · Nov 4, 2011

I am building loader brackets for a 3320. Does anyone know what the sizes are for the bolts that are on the sides under the grill? I know there are 2 different sizes. The front ones are the ones that I can't figure out without going to town and buying 4 different sizes until I find the right one. Thought someone might be able to help. Thanks.

Hi, if the holes are normal type loader brackets then they are likely to be M16 coarse especially if they are tapped into a casting. They could be M18 coarse. They are not likely to be fine thread.
M16 in diameter is equivalent to 5/8" unc but the thread is not the same.
M18 will be in the region of 13/16" but there is not a close equivalent.
