Combines Variable Header Speed

If I remember correctly, the sheave is not suppose to come clear together(space left between) when the belt is tightened to the proper length. Check your manual and make sure you have the proper clearance between the sides of the sheave. Tighten the belt tightener screw. It will shear the shaft if the piston is able to close_ over-close the sheave spacing. Good luck!

make sure you use proper spacer on lh bearing.(betweem bearing and undercut shoulder)lh bearing uses no lock collar.assemble lh side and torque nut to specs. use loctite on bearing to shaft area. tighten lock collar on rh side after lh end nut torqued. this torquing is to help preload bearing against shoulder and add nore strength via the special spacer.hope this helps.

like John said check belt tention first. The relief setting is somewhat varible. Relief is controled at a lower than master relief by how fast oil can get threw one orfice and then leak threw a .104" needle seat. Make sure proper seats or orfices are in there for reel speed increase and decrease. Also be sure all is well in torque sensor. Plum in a pressure gauge to see what you have and I would say you should be in the 500PSI range.

Make sure corn is not pulling to hard.One guy I know broke 2 on N5, the corn pull so hard.It was the rollers worn out.

Make sure the corn head is not pulling to hard. I know a guy broke 2 in row on a N5,Because rollers where wore out, it pull that hard.He put on new ones and never broke again.

if belt is adjusted right or not to short,there should be some give between bottom pulleys when speeded all the way up. put a crow bar between bottom pulleys and if you can't spread apart a little bit somethings going to break. have seen several lock collars in the wrong place like mentioned earlier also is the snap ring on back of hub still thereIJ in around 1982 they maid shaft with 1-1_8" nut and have broken very few since then,you had to grind stub shaft out to get over nut or buy new stubshaft.
