Good afternoon,


Decided to do my first oil change, all went well, until I tried to putting on the new rubber o ring . I've cleaned the area, and it will not stay in. Once you get one side in, and work your way around very slowly, it eventually comes out from the other side.


I've leaned the bike , and had another helper assist, with no such luck.


So, a 30 min oil and tranny change, has me leaving it for another day due to the rubber o ring dilemma.


Any advice would be greatly appreciated.


Feel like an idiot

 

If you mean the large o-ring on the inside of the derby because of a gear oil change....

The derby should have some very small "****" on the groove into which the o-ring sits.
Gently set the o-ring groove.
If the o-ring falls out, apply very little grease to small sections of the groove to hold the o-ring in place.

Also be aware of your clutch adjustment when removing the derby.

Good luck and have fun wrenching on your Sportster.

 

Thanks, I was able to line up the o ring on the inside of the cover and gently put back on , rode in this morning, so far all is well

 

Another method is to drain the primary like usual BUT, refill it through the inspection cover. Much easier... just dump in a bottle with a long neck funnel and you are done.

Just don't get stupid with the bolts. Treat them like babies. Be super gentle. Tiny bit of blue locktite. I dont even torque mone to spec. The primary is made out of butter. And will easily strip out threads or crack

 

Great idea, Thanks, and I also used some anti seize on the primary bolts.

 

I'm not sure I would use anti seize. That makes it easier for disassembly. We use it all the time at work but I wouldn't use it on my motorcycle. A torque wrench and a little blue loctite if you are having an issue of the fastener coming loose frequently. If not just torque it. But like said above the aluminum casing can strip out easily.

 

I coated the O ring with Chapstick. Stayed put easy

 

I dont think anti seize is a good move there. They may vibrate out.
