250B Oil Drain Plug, Spring, & Screen ?

Here is a pic to help. Don't know the motor type yet.

Thanks Glass ... no ..didn't ask yesterday ... was distracted by the bikini bike wash ... lol.
CFMoto eh ... now I guess I know what direction to take.

Thanks again!

Did you drain from the side or the bottom? If I'm not mistaken the CF Moto motor has the side drain and the bottom drain, and the Linhai motor only has the bottom drain...but I got a wicked headache right now so what do I know?

Where's the side drain on the Linhai motor?

I could be wrong as I was comparing it to my Morphous which it most closely resembles.

barry your screen is behind the side drain not the bottom if you hav a cfmoto engine that is.

the drain on the bottom (17mm) does not have a screen and you drain from the bottom, not the side.

once in a while you need to remove (ccw) the side oil screen access. pull the spring and screen out and check to see if it is clean. watch how screen comes out they had the spring backward on mine they had the loose end of spring over the screen not allowing a good seal inside the screen area.

put the screen over a finger put it in spring, should be snug put it back in engine. spring should be sitting on rubber ledge of screen making a contact all the way around.

When I changed the oil while doing my PDI on my 250B Linhai, I found a brass colored washer in the drain pan, I imagine it came out with the oil, but I don't hink it belongs in there, anyone else see the same thing, I would hate to have to drain the oil again to put this washer back.

i see the plug, screen, and spring, but that other piece???
that came out of the crankcase when you drained the oil???

further proof that a thorough PDI will save you much grief.

beats me, my scooter doesn't have that either.
Like widehide stated check to see if it is magnetic or not.

that piece would be loose in there wouldnt it??? what would keep it from blocking the oil flow thru there oil flows toward the unknown piece doesnt it?. magnetic or not it is loose.

i would not want anything crowding that area or slowing down oil flow. the fillter screen is enough of an obstacle to oil flow when cold.

i would not put back in.

OK this little cylindrical part that fell out on you is a insert to extend the oil pickup down lower to be about even with the bottom of the crankcase, so it can be assured of sucking up oil, even if the oil level is low for any reason. Not just letting the oil level get low, but in periods of around WOT, at high RPMs, the oil pump can suck up more oil than is draining back into the crankcase oil sump. Another reason one shouldn't go WOT for long periods of time.

On my scooter the oil pickup extension appears to be a light press fit or interference fit into the top as shown in the picture. It didn't move or jiggle when I touched it with my finger. the large end goes in first with the smaller end extending down as shown.
