I have a 1640 don't think its much different than a 1440 but to your Shaft Monitor problem we where taking wheat off about 4 years ago everything was working fine put the machine in the barn for the night and next day the monitors where dead well traced it down and found a mouse or rat had chewed thru a Ground wire for the monitors during the night This wire was located in the access panel on the ladder side of the cab right under your side window wire shield was still intact on one side so at first all looked ok but grab and gave all the wires a tug and sure enough it snapped apart harness is a bit on the short side hard place to work soldered it back together and used liquid wire shield and taped it hope this helps u out and the clunk sound is it coming from your return elevator IJ theres a steel paddle that keeps the elevator clean it makes a noticable clunk at lower Rpms
