I took apart the H55F -gearbox and transfer case of my HJ61 and found some wear. The gearbox worked ok, some minor rattle in neutral, at idle could be heard after highway drive, when the oil gets hot and thin. Some vibrations at low rpm and especially on fourth gear could be felt. It didn't pop out of gear or anything like that. 2nd and 3rd need a little attention to shift but it's more like a feature in these old boxes I think. The main reason to do this rebuild is that I want to make sure that gearbox, transfer and power take off are strong and reliable... and because I've been dreaming a long time of rebuilding a gearbox without any hurry and learning more of them :)
