Superbike swingarm swap 998r
Up to Faq's & How-to's
Posted by
Background:
Long before I had a superbike, I came across a Dymag CF swingarm for sale on the Ducati Index. I got it hoping someday that I'd have the right bike to put it on. Later- a 998R came into my life and it seemed like a perfect match.
A swingarm swap is pretty straight forward. You can see everything you need to do but there are a couple little surprises. From my memory here is what was done:
NOTE: This is not a definitive way of doing this job. It is meant as a guide/resource for those who may be considering it. Always double check your work, torque settings and use loctite where needed.
1. Put bike on stands
2. Remove Rear wheel
3. Remove rear caliper and place out of the way (you do not have to break the line)
4. Slacken chain and remove off big sprocket
5. Remove exhaust pipes/rearsets to access engine/swingarm pivot bolt. (I also removed rear tail and bodywork so not to scratch)
6. Support the bike from ceiling because the rear stand will be ineffective soon. We used a step ladder with a strap and blocks under the engine.
7. Remove lower shock bolt (frees shock from swingarm)
8. Loosen swingarm pivot bolt and remove bolt. (This may require some serious effort with a BFH. In one instance while removing an engine it took 4 hours (first time).
9. Loosen rear motor/frame bolt completely but leave in.
10. Spred the frame at the swingarm to engine pivot ~1/2in. (Note Haynes manual tells you to remove engine to do job, another method is to pivot the engine out of the way. The swingarm bearings insert into the frame so even with the bolt remove the swingarm will not drop.)
11. Remove swingarm! Jump for joy!
12. Reinsert new fully prepped swingarm again spredding the frame. (Not make sure the chain is properly positioned for install)
13. Lube/grease swingarm/engine pivot bolt and reinstall.
14. Retorque engine/motor bolt.
15. Install lower shock mount. (you can now reuse your rear stand.)
16. Install pipes, rearsets.
17. Put chain on rear sprocket and adjust.
18. Reinstall rear caliper (you may need a new brakeline if you install a longer swingarm (I did) or the routing of the line is different)
19. Reinstall rear wheel
20. Reinstall bodywork
21. Drink your favorite beverage in celebration!!!!
It took 3 guys who had never done this before 5 hours. I know of a guy who did it himself.
Tools needed: metric sockets and allen wrenches, torque wrench, BFH, stands, eccentric chain adjuster, frame spreding tools.
Overall I rate this job a 4 on the scale of 5 in difficulty. Harder more involved than fork swap but easier and less time than engine swap.
