got to disagree on this one worked on hysters for 19 years so i know what im doing never pulled a mast or axle to do the tranny far easier to pull the engine agree its about a 16 hour job and definitely use permatecs 11 on the edge of the seals. On the sealing face of the diff and tranny use a thin smear of gasket sealer and make sure the joining bolts are tightened to the correct touque cant remember what it is now.
