Here's a photo of a 50h from a good friend of mine.

The first thing I like to do with these is pull the left ring and grease it underneath, then grease all the screw holes.

The left ring goes back on, and the right side plate comes off. Three side plate screws is all you need.

Lube the left side plate bearing, put a little grease on the clicker and spring. Next to come off are the handle lock screw (key #52), the handle screw (key #51), the handle (key #50), the handle washer (key #49), the star drag (key #48) and the drag spring washers (key #47).

Back out the four set plate screws (key #35). At this point, the reel goes "boing" and you're committed!

Boing! Lube the right side plate bearing now.

Here's a shot of the jack assembly after it has been cleaned up, and the drag washer assembly prior to cleaning. Note all of the oil in the drag washers. It was no wonder the drags were sticky.

Now I've cleaned everything up and switched out the stock drag washers for the Penn ht-100 drag washers. The drag washers are still dry at this point.

The drag washers were then greased and set plate assembly was put back together. It's a basic three-stack similar to what you see in the Jack Erskine picture below. Thank you, Mr. Erskine!!!
