ive been working on repowering a 743 that had a wore out kabota v1702 in it. Repowering with a v2203. Skid Steer had lots of small issues that just added up to a PITA. In addition to another engine, i replaced the main seal on the back of the hydro pump, new radiator, muffler, seat...in addition to going throu the entire wiring system (nothing worked...all abandoned except for ign and glow plugs...all gauges and idiot lights working now). Have started it up, but still have some minor issues to fix...plus im rattle can repainting it too. Plus adding LED lighting.
