I got a stihl 031 and I have just put it back together with new seals and gaskets. After running the saw without cutting in wood a pretty good amount of oil runs out of the bottom of the saw between the guide plates and then down. I have it set on the lowest setting I think. is it normal to get oil running out of there without cutting in wood. It did this before I took it apart. I ran it with bar and cover off and The oil was coming out of the oil hole and no where else. Just seems like there is a lot of oil running down. Bar holes are clean. I am using an oilomatic chain. thanks.

Ok, so you're running it with the bar off, or no? You say it's running down between the guide plates. These are the plates on the clutch cover, and the plate on the saw that skirts the bar studs, and holds the tensioner on? If those are the guide plates you're speaking of, and the bar is off, then yes, you'll get oil coming out, and a good amount. Then you mention bar holes, and Oilomatic chain, which makes me think you have the bar on. The saw oils when you're on the throttle, and not while idling. If it's coming out of the oil hole, and nowhere else, I'd call it good. Stihl's are often a bit behind the power curve on oiling, so if you're getting all the oil you need, go cut some wood!
Take care all,

The oil pump is driven by the sprocket; so long as the chain isn't turning the pump isn't pumping. I'd be concerned if oil were running out if the saw were just sitting, and it was leaking somewhere other than the bar oiler passage. 031s are pretty tough, so you're probably fine.
BTW, sometimes the new saws leave something to be desired in the oiling category, but the oldies like 031s, 045s, 050s, etc... oil like there's no tomorrow.

I have an 031 AV and the oil pump is not driven by the sprocket. yeesh. It is driven off the crank shaft. It pumps oil even at idle. The sprocket is only held on by the clutch. Take out the plug push in some rope into the cylinder and take off the clutch by rotating counter clockwise, and pull the sprocket if you don't believe me and see for yourself.

DirtTroll: If the clutch screws onto the crankshaft, then it has to be turned clockwise to remove it, otherwise it would unscrew itself. Some saws have a nut to hold a splined clutch in place, in which case the thread could be either left-hand or right-hand.

Well, you made me pull out my parts list. Near as I can tell, I'm right. There is a little pin that connects the sprocket to the gear. The gear rotates around the crank but is not directly driven by it. This gear meshes with the oil pump gear. Identical to the 045 and 056. Maybe Stihl changed it, but I doubt that.

Mine pump gear is turned by the clutch not the crank. Im mainly concerned with the amount of oil that runs out of the bar cover area when im running the saw without it being in wood. seems as if more oil is coming out of bottom than getting on the chain.

Is there a chance that this oil is being slung off the chain as it goes around the sprocket? Try cutting some wood and see if you still have that problem.
