Just got a 4430 QR.
It has some hydraulic issues. In low, the SCVs, steering, and other hydraulic functions are slow or inoperable. The trans also slips when a load is applied. The problem seems to be intermittent, it works fine until the tractor warms up, and sometimes even when it's hot and the RPMs are high, it will work okay.
I have changed the filter, cleaned the sump screen, and ensured the fluid level is okay.
It seems to me that the primary pump is starved of oil when in low, either the trans pump is bad, or there is an internal leak.
I have read about a pipe that may loosen on the planetary 2 speed drive, creating an internal leak, part #R60523. How does one go about checking if this pipe is the problem?
