Dads old dozer, a 1977 350C, 6 way blade, 1350 hrs (sn:279xxxT) has sat 10 years, engine periodically run. Last time dozer ran, dozer stopped moving in F and would only move with reverser in R.
Engine starts and runs good, hyd system is good except for a few hoses, has new sprockets and pins and bushings. Rest of U/C looks good and no cracks in frame or supports. Could use a little paint and new seat but mechanically in pretty good shape.
Started messing with it recently. Test gauge is 120psi in N, 140psi in F or R with Trans in N. In R, engine loads up as clutch is released. Shifting reverser to F, without pressing clutch, pressure stays low, about 40psi. With clutch pressed, with reverser in any position, cant shift trans into any gear, just scratching.
Any thought on specific issues? I think one of the clutches (R) is sticking. Dozer is located about an hour South of Dallas and will be looking for a shop to rebuild reverser if needed.
