This issue is frequently caused by a faulty 201-60-65170 solenoid valve. If the electrical signal is received but the spool doesn't shift, the swing brake won't release. We recommend checking the coil resistance first. If it's outside 30-50 ohms, replace the unit.
A clogged or failing 203-60-56560 solenoid can restrict pilot oil flow. Identify potential risks during maintenance by checking for metal debris in the valve screen. If cleaned and still failing, a replacement part is needed.
Our parts feature an OEM-standard tri-metal structure and are trusted by repair shops & equipment fleets worldwide for engine rebuild, overhaul, and daily maintenance.
