Hello quantech

"<font color="#6699ff">[b:654c4848f0][i:654c4848f0]Do you have a tip for bolt removal, and then replacement with bolts that have the right size nuts for the hex slots?[/i:654c4848f0][/b:654c4848f0]</font>"

This is one method of removing and replacing the cutter bar cap screws.

First block up the support and yoke.



Block up the frame.



Block up the cutter bar near the inner shoe.

Leave enough room to work underneath with a wrench.



Block up the cutter bar near the outer shoe.



Remove the inner shoe.



Remove the smaller shoe and dowel pin.



"<font color="#6699ff">[b:654c4848f0][i:654c4848f0]the four bolts under the inner shoe that secure the cutter bar cannot back out as the nuts spin the in the hexagonal "seats"/"valleys" making it impossible to get a wrench on the nuts to keep them from spinning.[/i:654c4848f0][/b:654c4848f0]</font>"

Apply a abundant amount of your favorite penetrate to the lock nuts.

Use a large, flat-head screwdriver.

Drive the flat-head between the lock nut and the ?hexagonal "seats"/"valleys" as tight as possible.

Keep one hand on the screwdriver applying pressure and the other hand on the wrench.

The ?wedged? flat-head screwdriver should keep the lock nuts from spinning.

Be patient because this might take a while to remove the back cap screws.

You might consider using Category 8 cap screws.



Replace the lower shoe using the 5/8 x 2 cap screws and lock nuts.

The parts catalog lists a 5/8 x 2 ? cap screw, but the shorter 5/8 x 2 cap screw allows better clearance for the knife drive yoke.



Continue replacing the lower shoe using the 5/8 x 2 1/2 cap screws and lock nuts.





Replace the dowel pin.



Hope this helps.
