Sorry Steve
Sorry Steve I've been at meetings for the last couple of days. As for your stuffing box.1) Clean that thing up as best you can! Wire brushes, Scotchbrite, Dremel & wire brush etc. etc.. 2) Clean that shaft but don't uses abrasives, in lengthwise motions, or your stuffing box will leak for a while until you "polish the scars out of the shaft" with the packing. Always clean the shaft in th same direction it spins. Kind of like "sand with the grain of the wood". What the heck is that "yellow caked on junk"?3) That box should take at least three rings and the adjusting instructions are similar to the "nut type" box.4) Confirm how many rings you pull out and replace with the same unless it was two and CAN fit three.5) Make sure you have locking nuts for the compression device!It looks like a fairly straight forward water lubed "competition style" stuffing box and the basic concept is very similar to the directions on my site you've already read..If you have any more specific questions fell free but the photos DO help a lot!!
