Hex key size for oil screen drain
Posted November 19, 2009 - 06:03 PM
Did a search and did not find specific info on what I am needing as well as asking the same thing over at KTMTalk with no response. Went to change oil for the first time last night to find I did not have correct size hex key for the oil screen on the bottom of the engine. Any ideas what the size is..I am thinking 12mm. Also this has probably been beaten to death but I am reading 1.3l for change and manual says 1.35l, which is it. Final question is how important is it to remove the oil screen with every change? Thanks in advance.
oh yeah, bike is 2008 450SXF

But it is bigger than 10mm as I have one of those and it is too small, are we talking about the same bike? I know the XCF or something has the 8mm one. This bike is a SXF (RF4 engine) 450. Thanks.

As for removing the oil screen every time, I guess it depends. In order to get as much oil out as possible, you need to remove the oil screen plug. Some people think it's necessary to get ALL the old oil out, some don't. I personally don't remove the oil screen plug (and hence the oil screen) every time I change my oil. This is due to me being lazy and not wanting to take my skid plate off all the time. If I didn't have a skid plate, I would probably remove the plug to get all the oil out and clean the screen while I'm at it too.
The manual calls for 1.3L of oil. I usually put in about 1L, start the bike and let it run for about a minute, then top off what is needed according to the sight glass. This is probably not the "correct" way to do it, but it works pretty well for me.
My oil schedule (only trail ridden, never raced, i.e. "easy" hours):
Change oil: 10 hrs
Change oil filter: Every 3 oil changes
Clean screen: Every 3 oil changes

Tapping it helps, as does having the cases warmed up.

In u.s., I know it is bigger than 3/8 socket driver and smaller than 1/2 driver. Seems like ktm would include a oil plug wrench, I thought maybe my wrench was left out.

Autozone sells a 3 pack of hex head drivers that fit on a 1/2 drive ratchet. One of them (12mm?) fits the oil drain plug and another fits the plug in the ignition cover. I went to three different hardware stores and was getting very frustrated looking for these as no one seems to carry them but autozone saved my day.
