How do you Drain Crack Case Oil?

I just picked up a 1996 Ultra SP and I going through the whole sled. Adding grease to the jack shaft and any where else I can find a zerk fitting.

I also want to change the crank case oil but I'm not sure how to drain it. Fuel filter will be replaced, also is there a crank case filter that needs to be replaced??

I'm not to familiar with that sled, but , if it's like any other sled ( until recent years) it's a 2-stroke.....No oil/filter to change!
If it's a 4-stroke then I have'nt a clue.

Looking from UNDERNEATH the sled find the chaincase area. You will find that the belly pan has a circular hole in it. About 1" up is a allen head flush mount screw that threads into the bottom of the chaincase. Be careful, you will more than likely need a metric allen head driver or wrench to loosen this screw. If you use a SAE size you can strip the inside (part that the allen head driver slides into) out of the screw. Been there, done that.

Pre- 98' I don't think you'll find what accobra66 was talking about. With the chaincase just pull the 4 mounting bolts & make a mess... Its only like 12-14oz or something like that, so just have a couple shop rags available. Polaris was smokin' crack with that design...
There is no filter or pump with the chaincase. Just oil sloppin' around in there.

If your looking for a crankcase filter. With a 2 stroke moor it is a dry environment. Nothing is but air in there.

That maintenance is supposed to be done once a year (Polaris). If you guys see, that oil is dirtier than hell...someone told me it was due to the stock "powder" gears.

I use a suction gun about the size of a grease gun to suck most of the oil out of the case before opening it, that way there is a LOT less mess to clean up... you definitely want to remove the cover so you can take a look at the gears and chain, some times you find surprises!
