    I believe the small access hole in the driveshaft tube is the driveshaft tube vent, not a grease/oil fill. If I recall correctly, it looks like a brass hex nut with a hole in the middle on the outside of the motor on the Port side of the mid section. I own a couple of the HD-25’s, and they take 90WT. I’m not 100% sure about the HD-20, but if it doesn’t leak with the 90WT, then your probably OK.

    By the looks of MarvK’s second picture that driveshaft tube needs some venting. I have an HD-25 that has the same situation with that nasty looking spooge leaking out of the same vent. Some time ago, someone posted a picture with that similar situation and they attributed it to a loose gasket. The specific gasket was not mentioned though.
