After many efforts of stopping hydro/oil leaks including axle seals, pump mounting gasket, etc.; there's one left; the trunnion shaft seal. Page 2-48 of the Service Manual shows driving pins from the swash plate to remove the shaft. A Sunstrand book explains replacing seals externally, but with IH I'm thinking there's a tear down involved because of the arm attached to the trunnion shaft for the linkage/quadrant. Is my thinking on the right track??
