hobart h-600 dough mixer oil leak
hello. looked at an old hobart h-600 mixer, literally all the oil from the transmission leaked out into the bowl.
I found the lower bearing on the clutch shaft disintegrated and pushed the expansion plug out the bottom thus releasing all the oil. dissassembled the transmission, doesnt appear to be much damage except the bearing. my question is about the expansion plug ,from what I can see it is the only seal/barrier holding the oil in the machine . does it simply press into the casting ? do you use any kind of sealant on it? there isnt anything i can see in the service manual about this , has anybody ever dealt with this ?
thanks
