Noob here with a question; I am going to change my rear sprocket to a 47 tooth sunstar along with a new o-ring chain. I searched for threads relating to problems that I might encounter when removing the rear wheel but couldn't find any. Any suggestions?



Regards,

Charlie

Use the stock bolt locking hardware and Loctite on the nuts. Other than that, it's a straightforward project.

Hey K9, I just did the same project, but went with a 52, and it was very straightforward. I took the time to clean everything up real well while I had room, and found alot of dust/crud in the rear brake. I don't use the rear very much, so parts looked new, but there was alot of dust in there.



Other than that, have fun!

If the new sprocket is recessed where the bolt ring is be careful you do not bottom the bolts on the threads prior to tightening on the hub.



Lotza of torque on bottomed out threads = 0 torque on sprocked/hub interface.



New longer bolts or washers cures the problem.



If you get new bolts do not use bolts that are threaded their whole length. Threads inside the material you are securing is not a great idea. In fact in most aircraft applications it is not allowed.

I just did mine 3 days ago and no issues. If your going to knock out the axle bolt use a rubber malet so you don't screw up the thread on the bolt. Once you have everything apart put a thin layer of greese on the axle bolt before reasembly. Have fun.
