Sram rear derailleur rebuild..

[Mr Universe]

Sram 9.0Sl rebuild.

Not sure if this would be of any help/interest to anyone here


Personally I'm finding the restoring part of the hobby for me is the most rewarding,..being able to take something that most people would throw in the bin and make it look nice again is most satisfying

So I rebuilt this derailleur a while ago , but never got around to posting any proper pics

Although I will say now,

I apologize for the quality of the pictures, at times somewhat blurry..

.. but given it was really tricky holding the part, either open or in a position a picture could be taken , whilst also holding onto my best m8 'JD' in a glass and the camera all at once .. :facepalm:


Anyway

So..

It was in poor shape and not really in the cosmetic condition I was wanting, so I started by removing all the basic screws and bolts, and worn jockey wheels , etc.







Then onto removing all the retaining pins and tiny cir clips on the 'knuckle' part.





This then enabled for me to get at the internals, also allowing me to removing the return spring from the retainer stop . .









It was not the best state internally





Then onto removing the retaining pin for the main body spring return mechanism, not sure of technical terminology but hopefully the pictures explain what I'm doing.



That then enabled the separation of the main body from the derailleur plate.





So now I've got a bunch of parts ..





All the individual parts were then cleaned and degreased then made ready for the SFX Booth







Ovens are for cooking ? right





Time for a break Part 2 up soon..

Never thought of doing this. Always just bought a new one. Or bought carbon replacement parts to loose weight and sex them up.

What paint used? Oven to ensure paint fully cures and hardens?

Good effort, theyre nit that duanting, later version dont have circlip but a fifferent clip that deforms, you need to be careful as it will snap aftef too many remivals and fittings, unlike the spring cirvlip on yours.

Hi,

Thanks for the interest

I used an automotive disc calliper paint and primer.

I'd pre heated my conventional fan oven to 180, then dropped the temp down to 120 and baked the parts for 30 mins

I'll add also that I pre warmed the parts in the oven after initial base coats of primer, prior to laying down the top finishing coat of paint

later version don't have circlip but a different clip that deforms, you need to be careful as it will snap after too many remivals and fittings, unlike the spring cirvlip on yours.

To be honest I think this production year of derailieur is about the most modern part I actually own , so hopefully I'll not run into any of that nonsense



Hi Mike

Was this on the now slaughtered moo moo?

Mike

Yes its the same one, first time I've had time to post anything up tbh


Moo moo is not Slaughterd btw.. she lives

Re:

Part 3

After reassembly .. *Warning, not advisable during alcoholic consumption* :facepalm: , a little tricky but well worth the efforts imho.




Et Viola...




Hope this may be of encouragement for some other members to refurb rather than re-purchase

Feel free to contact me or ask on the thread if anyone needs any further advice re this rebuild.

Did you have any problems fitting the aftermarket jockey wheels?
