these are great little 30# reels. to rebuild the old daiwa sealine 50h, you need four penn ht-100 drag washers. one is part #6-855 from the old discontinued penn 855 line counter. three are part #6-114, from the black side plate 6/0 penn 114. i just now found this great place called mike's reel repair while i was looking for the schematic for this reel. here's the link to the schematic. thank you mike, wherever you are!!!!!!!!!!!!!!!!

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 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!!!!!!!!!

the four set plate screws (key # 35) go back in.

place your left index and middle fingers over the four screws and flip the side plate over. with your fingers covering and holding the screws in place, you can work with the side plate and not worry about the screws falling out. same with the penns.

install the two clutch springs (key #26).

install the pinion yoke (key #25) and the pinion gear (key #21) as a unit.

install the eccentric jack (key #24).

install the set plate/gear/drag washer assembly as a unit and rotate it 90 degrees counter clockwise from it's final position.

install the anti-reverse claw (key #33).

rotate the set plate assembly 90 degrees clockwise and push it down and in place.

tighten down the set plate screws.

install the anti-reverse claw spring (key #32).

install the all part key #'s 46 through 52 in order and you're done! congratulations, it's miller time. with this particular reel, i drilled out the old grip and installed one of my custom off-set tapered grips. i spooled it up with 30# mono and got a max of 15#'s of drag at the top of the spool. i backed off the drags, boxed it up and sat down to type this report. elapsed time, 2 hours.
