Can't help you with your issue, but this Komatsu unit is the same as a Clark OP15 & Prime-Mover model OE35. Unit was made by Prime-Mover in Muscatine, Iowa, the plant now produces equipment for the Toyota group after Toyota bought BT (which was after BT bought Raymond which was after BT bought Prime-Mover (sounds like a story from a mountain top in Tennessee).
