Bought a rough 6700 at a consignment auction last week. Drove it home 35 miles pulling a 6rn planter. herded it home would describe it better. . It drove like an older tractor with a real worn steering sector. Has a half turn or more of slop between turning one way or the other. Wanted to wander this way and that. haven't done much troubleshooting yet. Checked the tierod and cylinder linkages and they are tight and has a slight amount of toein. Steering pump is weak but it steers reasonably well as long as you are moving. The only thing left is the steering motor. Is there a way to test this, or should it just be changed given the symtoms.? Or could there be slop in some of mechanical linkage between the steering wheel and the steering motor.? thanks for any insight you may have on this.
