HST on my L4740 has not worked right since getting it back from the dealer after an engine replacement. Also had them change the HST fluid and filters. Now I got this in an e-mail:
"We have ran some test on the tractor. The internal hydraulic pressure on the transmission is low. Book spec shows about, 4950-5680 psi, forward and reverse HST pressure. Actual pressure on your tractor is 2200 psi.
The transmission HST pump or motor has a failure. We will need to disassemble the transmission and overhaul the HST system to repair. We will put an estimate together for you."
The HST was working perfect before this work was done. Could they have damaged the HST by performing the other work? What does it cost to rebuild a HST? Thanks.
