retr83…….I sold the Hustler frame last year with the grease port BB still fitted and going strong. I have done the same mod to my current Orange 5 & 160, with the exception of fitting 2.5mm grub screws on the 160 instead of the Zerk ports. This was due to the BB shell wall thickness fouling the Zerk port when tightened fully.
I think there is a bit of a misconception about why the none drive side bearing usually wears out 1st. Some folks recon its to do with the preload being on that side. The preload nut pulls the drive side arm as much as it pushes on the none driveside arm, SO the bearing preload should be equal. The main difference between the two sides is the protection the driveside bearing gets from crap thrown up by the front wheel, ie. the chain and sprockets etc. The none driveside arm has a gap at the back that lets the crap in.
If you are going to the trouble of splitting your HT II BB to regrease, take extra care of the inner surface of the plastic top hat insert that the outer seal runs against, and the seal itself. SEALS need lubricating as well as bearings. A dry seal will wear quicker and let crap in to destroy the bearing.
