Hello, I have an older (1979?) Erickson LM4D skid steer loader. About a year ago I replaced the Onan motor with a Briggs Vanguard 23 hp motor and things have worked well. Yesterday the machine was being used and abruptly stopped moving (wheels and bucket up/down and tip). I towed the loader out of the way in reverse while the wheel controls were held in reverse to minimize the resistance... While doing this I was able to move the bucket likely from the induced pressure from using the wheel motors as pumps?
That all said, does this seem like the hydraulic piston pump has failed? If so, does anyone have any recommendations for tracking down a replacement pump or rebuild parts?
