and here are the reels. except for the width of the spool, frame and spool shaft, the reels are identical. these reels were shipped in from hawaii. the freespool was very poor, but these reels were still in good enough shape to kill fish.
by now, you all know the drill. pull the preprogram dial (key #9), the dial spring (key #82), the lever shaft body and "O" seal (key# 10 and 11), and the drag control lever (key #83).
remove the lever quadrant (key #192) and screws (key #19, 21 and 86).
remove the seven side plate bolts (key #24).
separate out the frame, spool and right side plate assemblies.
let's start with the frame first. grease up the click spring (key #101) and click pawl (key #231).
these old wing nut clamps are great for gouging up the gelcoat of a boat. let's get rid of them.
the graphite clamps are much better. ok, that's it for the frame.
now for the spool. once again, the cooling shield (key #89) was loose. note the rubber gasket that seals up the drag chamber when the reel is in gear. remember to keep this and all of the shimano graphite lever drag reels in gear when they will be exposed to water.
remove the drag plate assembly (key #196, 60, 91 and 31) and set it aside with the cooling shield.
now for the left side of the spool. remove cross pin B (key #50).
remove the click gear (key #98) and screws (key #99).
pull the main shaft (key #173), keeping the bellevilles, thrust washers and bearings in order.
these bearing are gummed up, but not rusted. with a small pen knife, pry out the shields and let's clean them out with carb cleaner and compressed air, then lube them with corrosion x. by cleaning the bearings rather than replacing them, we'll save someone $40-50!
now we're going to change the configuration of the bellevilles (pre-load springs). the original orientation of the pre-load washer A (key #72) and the pre-load spring B's (key #96) is "|()()" and the thickness is 4.61 mm.
we're going to toss the flat washer and add a fifth pre-load spring B. the new configuration will be "(()))" and the thickness is 4.52 mm.
back into the spool it goes.
grease the screw holes.
install the click gear (key #98), screws (key #99) and cross pin B (key #50).
