I am in the middle of doing my first oil change on my own without the dealer. I am now looking for the Engine Sump Drain Plug. It tells me that approximately 1 cup of engine oil will remaim in the crankcase. To drain remove drain plug found on the lower right side of crankcase.....That is the rear brake side correct?......Also I did not remove the oil hose connection between the oil tank and pump inlet so oil pump priming should not be needed right? This only needs to be done when the hose with the filter screen is removed...Correct?......All the post that I read people have done this only to find the screen clean.....I will do it next time(every second oil change)......Thanks.....I know I read about this before but just want to find the Sump drain plug????

Look under the atv from the rear brake pedal side. Look for a cut out in the skid plate. Look up through the cut out and you should be able to see the 14 mm plug.

 

i do beleave that is the only cut off inthe skid plate where it is. could be wrong been a while since i looked at mine.

 

Thanks I will check in the morning....Do I need to do the oil pump priming after draining the Engine Sump drain plug....Or only when the hose is off for the screen!!!........Thanks again...Caper....
do you guys drain the 1 cup that remains in the crankcase....or just leave it?......Caper.....

 

I drain it.

It is my understanding that you don't have to prime the pump if you don't take the lower hose off. I had never even heard of priming the oil pump until recently. I've had a 99 sp 500 since 99 and I have never primed it and I always used to take the lower hose off. Never found anything on the screen.

 

Hi Caper.. I did a write up on how to change the oil in a 500HO about a year ago... Should be the same for your 450...

I drain the sump bolt everytime. I dont take out the screen thou. I may next time.

I am such a nice guy Caper.. Just for you buddy... A walkthru [img]i/expressions/face-icon-small-wink.gif[/img]

 

just did my oil change on sunday(04sportsman 400) man aint that crank case bolt a***** to get back in.... i always do my own maintance ,and yes i always pull the screen and clean it i have never seen nothing on/in it (the last 3 times) but if there is something there i want to know about it,and get it fixed before its a problem....as far as the primeing is concerned i have never heard the(woosh) of air so i do the process twice(just to make sure) and then i leat it run for about 5 minutes just idleing..shut it off and check the oil after it settles mine holds 2qts.. i just got my highlifter springs and dyno-jet kit today .. got her loaded on the trailer so i can install the goodies some time tomorrow at work.....CLEAN THE SCREEN
