RE: Derby cover question
Hey Yellowhawk, I would find out for sure what the oil amount is required for your dyna.I know on most dynas if you overfill the primary you will experience clutch problems (like finding neutral)most only take 26 ozs. and the torque on those screws are in inch pounds not foot. No torque wrench, you might get by just snugging those puppies down. Good luck, merry Christmas,have a blessed and safe new year.

When I changed my 01 Sportster cover out, I never could get it sealed even with a new gasket until I used some sealant around the gasket first. While you are in there, might as well check the clutch adjustment also.

you know things changed on dynas around 05 or 06 not sure but on an 07 it takes 32ozs. I would just keep asking on here and take all of the buy a service manual replys until someone with a manual givesyou an anwser. I can say on of the first things I got was a service manual.

Yep, I already got the buy a service manual advice. And, it's good advice. I definately NEED to buy a service manual. I was hoping previously to get the info I needed for the first fluid change before I bought the manual though. No big deal though.

RE: Derby cover question
Make sure you can remove the derby cover bolts before draining the fluid. I drained my fluid on my 07 Street Bob then I could not remove the torxs head bolts from the cover. It took 5 different torxs bits and a impact. Use only high quaility bits so you dont mess up the head of the bolts. I found a Snap On truck and bought the bit from them that would finally work without breaking. If you have a newer Dyna you must remove the derby cover to refill with oil.

As far as the fluid change goes, I haven't bought the service manual yet and I didn't get an owner's manual with the bike. I'm not sure what type fluid, quantity, or how exactly to do it yet. I would assume drain the old out the bottom and fill through the derby cover with about a quart of new?

An ounce less would be better than an ounce more.So, just dump a quart in her............ HD Primary lube is fine, or any 10w40/10w50 dino or synthetic, just stay away from those oils marked as "enery saving" (they're too slick). Some folks use ATF....... I wouldn't advise dumping a quart of bottled water in there
.Also, good advise on loosening the torqx screws on the derby cover first, just in case. Some folks have had problems, cuase the factory guys got em too tight, or had already stripped the heads on the bolts.
Your owners manual, covers most that info although a service manual is a very good investment.

RE: Derby cover question
Should also check what kind of gasket you have/need and pick up an extra one. I have the frisbee and have re-used it a few times without problems. Some people aren't so lucky with the o-ring gasket.
