I have a 1020 header 30ft that I use for my 2388, but the metal block that holds the knifehead keeps breaking 3x. Could this be the wobble box? It lasts about 3-4 hours.
try checkin the bushings in the wish bone bracket under the wobble box. they are located at the back of the header under the bottom their is two 50 hr grease fittins on them. They could be gone out. It will cause the plate that the guards on the knife bolt to break if they are no good.
