Default Derby Cover Install

Hey all,

My buddy has ordered a new Derby cover for his 2008 Fatty - Is it an easy swap out? Any mess or gaskets we need to worry about?

It's an easy swap, but you will need an old style gasket P/N 25416-99C. The newer models use an o-ring type gasket. Keep the bike on a jack so it's level too, to keep any oil from spilling.

Cool thanks man.

So no oil should leak if it is level?

You can reuse the same o-ring, its not an "old style" gasket on an 08.

Of course they would tell you to discard and replace. If you remove it gently you can most certainly reuse it. I swapped out my Derby for another and reused it - no problem. I have seen posts where others have said they've reused it a few times...
Its not an expensive item so I'm sure it won't break you to put a new one but you can make use of yours again if you so choose.

Easy w/those screws & use correct torx bit - they're probably tight from factory & strip real easy. Install in star pattern - just like tire lug nuts.

Hey Mongrel
To make this easy to understand, a direct replacement OEM (original equipment) part will require the original 0-ring gasket. Any of Harley's accessory covers are flat on the back side and require an old-style flat gasket.
Hope that clears it up for you. It's a simple 5 min job on a softail, 10 min on a touring bike as they require removal of passenger floorboard first. I always discard the "chrome" screws and washers that come with the "made in china" accessory cover and re-install the OEM hardware. Just my 2 cents....
