I have a 850c that would not go straight. All the motors and pumps has been checked, new speed sensors, new pcp's, electric harnesses checked, calibration done and no fault codes. Any suggestions.
Is it a john deere 850 or a case 850, or what brand if not those two? Oh welcome to the forum too.
Check the steering rotory sensor. If it is faulty the voltage could be changing when steering back to straight and the controller would take it as a good value and not set a code.
Are the track tensions close to equal? You may have a balanced drive with a mechanical issue causing it to pull to one side. Is it the same fwd/rev?
Sorry, it's a John Deere. The rotary switch was replaced and track tension is almost identical.
The dozer goes left in fwd and right in rev. Could it be that the pcp's is not nulled properly?
