Here is a Comprehensive Photographic Tutorial on how to Service and Maintain a Shimano Sustain FG5000.
This tutorial could be used for all the Sustain models - bar minor differences, they are pretty similar.













DO NOT unscrew the 2 smaller screws! They open up the Anti-reverse bearing with it's springs and parts.













At this point, you might choose to stop, because from here onwards, the Service becomes fairly complex and tricky.
With the gearbox exposed, you can use a toothbrush soaked in Benzine to remove all old grease, and dirt. Once done, allow to dry and regrease thoroughly.

For those who want to go further into a detailed service... Let's go!

Remove the Retainer plate at the back of the reel.





The Worm gear and Bushing















Clean all parts in Benzine, either soaking or scrubbing with a toothbrush. Allow to dry properly, then brush generously with grease.
RE-ASSEMBLY - Put it back together!!















Now for the Drive Gear...

Regrease and replace the Main bearing on the Drive gear









Awesome...
Now... for those who want to take it a step further....
HANDLE SERVICE





All pretty straight forward. No great problem to service the Handle.
DRAG WASHERS
Also pretty simple.
These are oiled felt washers. Do not grease them, they were meant to be oiled with a quality oil.
Now for the
LINE ROLLER - A spot on most reels that is most often sadly neglected.


The parts that make up the Line Roller...

into
To re-assemble, slide the bearing into the Grey Bushing from the lipped side. Then slide the Bushing into the Line roller from the thick side.
NB:
The Thicker side of the Bushing and the Line Roller both face the Screw side of the assembly.
Before assembling this system, lube all the parts with a good Oil.
THE OSCILLATING SLIDER



THE BAIL ARM MECHANISM


Now you can unscrew the top screw...

Be careful that you don't lose the CLICK PIN AND SPRING WHEN OPENING!!



Now you can thoroughly clean the Rotor of any beachsand and dirt. Scrub all parts with Benzine, and regrease lightly.





Now that's what you call a thorough Service!!
All done...!
