Read articles →An owner-operator walkthrough of installing a factory third-function kit on an LS MT473, covering solenoid valve mounting, wiring harness routing, hard-line and flex-hose assembly, and leak checking. The host specifically calls out one extra step the MT473 requires compared to the MT232, which makes this useful if you've seen similar installs and hit a snag. Best for MT473 owners doing the job themselves.
Posted by the Mallard 5 (+1) Farmhouse & Homestead channel, where host CJ appears to be a hands-on owner running multiple tractors on a working farm.
Mount the solenoid valve after removing its cover, run and connect the wiring harness, assemble hard lines and flex hoses with threaded fittings, mount them to the loader bracket, then check for leaks.
Yes, the MT473 requires an extra step installing a joint kit gasket behind the solenoid valve cover that was not needed on the MT232.
Yes, the video notes fluid is lost during the install and hydraulic fluid needs to be topped off afterward.
The owner calls it a pretty simple job with good instructions and pictures, saying if he can do it, anyone can.
