Shimano Bull's Eye 9120 -
Photographic Service and Maintenance Tutorial


A fabulous reel from the Shimano stable, suitable on the pocket and very capable in the Medium to heavy Rock and Surf Grinder Revolution range.

Made in Japan with the quality we are used to in Japanese fishing reels.



DISCLAIMER: This is a difficult reel to service! Ultimate Angling accepts no responsibility for broken reels! Use this tutorial at your own risk!
If you are not proficient in servicing Spinning reels, do not attempt the full service at home!

The tutorial below is in depth, but does not include rebuilding the reel. To rebuild, just follow the same steps in reverse.

I would recommend that you do one section of the reel at a time, before you move onto the next part.

The Schematics for this reel are in Japanese, so nomenclature is paraphrased.

Good luck Mike Pike!  :hehe:

Let's go!
Remove the Drag Knob and spool.




Remove the Ratchet clicker and support





Now take the Line guard off





and the Circlip that supports the line guard, along with the Rotor nut.




Remove the Rotor and this is what we have...





Unscrew the Anti-reverse mechanism with the 4 screws shown. The 2 middle screws dismantles the Anti-reverse entirely, leave these alone for the time being.





Take out the Pinion gear with it's bearing and support.




Remove the waterproof rubber O-ring along with the thicker one off the body of the reel.





What we have so far...





LH Side plate. Unscrew the 4 screws.







At the back, remove the Back cover.





Remove the Side plate





Remove the Drive gear bearing and it's 3 washers




Remove the Drive gear




The engine room.





At the back remove the Cover plate





Slide the wormgear and oscillating sliding bars out. Take note of the bushing orientation.







Remove the Drive shaft





WARNING
You should stop here, as the rest of the reel becomes very difficult to put back together once taken apart!





Remove the clutch pin and the Wormgear bushing






DO NOT REMOVE THE IDLE GEAR AND SMALLER DRIVE GEAR UNLESS YOU HAVE TO! They are very difficult to re-align.




Remove the remaining bearings.






The Oscillating slider







So we're left with this....




Clean all parts thoroughly in Benzine. Regrease with Corrosion Block and put back together! Easy Peasy...  :rotfl


THE DRAG SYSTEM






The reel has oiled felt washers. This is their sequence in the spool.




The Line guard has 2 little rubber end tubes. Do not lose these!




THE ROTOR and BAIL MECHANISM

Do not attempt this unless you are brave!




Remove the Cover and clean. Replace.




Unscrew and lube the joint. Replace. No moving parts inside.





Then on the Line Roller side....
WARNING:
DO NOT REMOVE THIS COVER UNLESS YOU ARE VERY PATIENT!!







Touching the Bail spring will send the spring flying into oblivion. BE CAREFUL!








Unscrew, but don't take apart. Just ease it open and spray with some lube.







THE LINE ROLLER

Unscrew carefully...!







Take important note of the orientation of the parts!







Put back together after cleaning and lube.




THE HANDLE

Clean and lube all the moving parts and Joints.




THE KNOB








Clean and oil both sides of the Handle knob and re-assemble.





Like the Ultegra, one of the more difficult reels to Service yourself. Do so at your own peril!

Now is not a good time to go fishing... said nobody... EVER!!

Now can I send you mine for service too?
Many men go fishing all of their lives without knowing that it is not fish they are after.

Ya some of these bigger Fixed Spool reels are really not easy to put back together. Too many finicky springs and gears that need to fit perfectly.
One needs to be very patient...
