Allis-Chalmers 72 combine in oats #2

[jimacman]

I am going to have to make a video showing the tab your supposed to push down to keep the belt from jumping off. 99.9% of the time that I have seen belts coming off it is not because of the belt, or too many twists it is because that tab is too far away from pulley. I have had belts that were half in grave and running on the side stay on, just to get the field done.

one thing that helps is to take the back belt off and hang it on a nail so it hangs straight. this is combinechris and sorry if i seem harsh hopefully this helps some of the problem of the belt

your belt has too many twists in it is the main reason it comes off. also it is not that hard to get a new one. also the wobbly pulley will throw the belt off too and needsw to be straightened.i have several of these machines and i don't have many problems with them. also need to open your wind up more.

I have that same combine and the back belt always comes off , tried to get a new belt but had no luck

is it true that this model had a 66, not a 72 inch cutting width?

[phoenixWI]

@1DanielChristensen the seperating area is the same as the 66 but the width of cut is 72 inches

Several reasons, that is a long distance for that belt to go without any support from an idler or another pulley. Also the shaker is causing jerks in the process causing the belt to jump a bit.

Why does the part of the belt between the idler and the shaker pulley wobbly?
