Homelite XL leaks oil

[doggerdan1]

I just picked up a used homelite xl. Seems to run ok and the oiler works but when the oil tank is more than half full or so, oil leaks out the bar oiler hole just sitting in the garage.
The little check valve that goes on the end of the pressurization line in the tank is missing, but I don't think that could cause it to leak.
It's like it just sits there and siphons out.
BTW, anyone have a part number for that check valve(or duckbill)? My UT number is 10515a.

Well Double-D you're in luck,one of the sponsors of this site has just what you need.Go here for the duckbill valve:

They also host the IPL for the XL here:

Good luck,those are fine little saws.

Sorry I didn't list you as one of the sources Calvin.I'm getting forgetful I guess.

Mine does the same thing. I dump the oil out back into the can after using it.

There are usually 2 duckbill valves, one to vent the tank, the other on the end of the pressurizing line. Some had an oil pump, some just used pressure into the oil tank to push oil out. I don't think either will prevent the syphon problem. If the one on the end of the pressure line goes bad or missing it can definately fill the crankcase with bar oil though.

I definitely need the duckbill valve, but I see there's also a little something they just list as a plug, item number 43 in the IPL. I wonder if that might be to prevent the siphon?
I did a little more research and on another site they call this item-plug, oil meter. I think I might be on to something here.
I did a search on both source sites listed for part number 93703-a, and came up with nothing.

what does that item look like ?

I don't know, mine is missing. lol
But you can see it in the IPL, item #43. I'm guessing it's some kind of a metering orifice.

Bump
Anyone have any idea why this saw will sit in my garage and continuously leak oil out the bar oiler hole? Is it just an inherent design flaw?
I'm thinking about trying to find a tiny shut off valve to install in-line to prevent this.

Gee doggerdan, It should not do that. Is it a Super XL? Or a SXLAO? Or an Xl 12? The reason I ask is the early Xl 12 had the oil fill under the muffler and the later ones filled from the top just in front of the top handle. Some of the later ones had a gear driven pump and some just had the thumb pump and still others had both. If it is a SXLAO (Super Xl Automatic Oiler) it must be somehow pressurizing the system. On those there is a large plug right behind the oil fill, under that plug is a cyl with????I think three o-rings. Check and see if those o-rings are ok. I've had bad o-rings before but all that seemed to do not allow the oil pump to pressurize the system (no oil) but check it out. You can try to crack that plug and see if the oil stops. I am operating from memory so I not quite sure but I remember that those are a real funny oiling system, lots of room for issues. How long will it leak oil with the bar off so you can see the oil passage?

 

[doggerdan1]

It's just a regular old XL. It has a pressurized oil tank system, no pump. It's been leaking oil now for 3 days, seems like it's just gonna sit there and leak until the tank is empty.
I filled the tank, cut about six 10-12" logs and the tank is almost empty, most of it leaked out in the garage.
I don't understand how it's doing it, because the bar oiler outlet is higher than the pickup tube in the tank, so it's not like it's gravity feeding out.

#43 is a restrictor to limit the ammount of oil flow. Mine syphoned out with it still in place. I think it's a design flaw. I thought I remembered them offering a checkvalve to fix the problem back when they were still being made, never seen one personally. I just dump the oil out with a funnel into the bar oil container after sawing.

That's a bummer. I got mine to carry on my dirt bike when riding mountain trails to clear dead fall blocking the trails. I might ride all day and only use it once or twice, it makes a real nice mess all over the front of my bike.

Sorry I was mistaken, I thought you had the larger XL 12 or Super XL (54.2cc. or 58.2cc) I guess what you have is the top handle XL (26.2cc.) I don't have any experience with those just their bigger brothers. Good luck an oily bike does indeed suck.

I just received the duckbill valve, it's the same little valve that goes in the gas tank. It looks like its way too small to fit on the oil line nipple though. Anyone know how that little valve is supposed to install?

 

[doggerdan1]

Boy this is really aggravating. There's no way this little duckbill valve will install on the end of the fitting. Mine has a little threaded steel fitting 3/16" diameter or so that threads through the plastic oil tank and sticks through the inside maybe 1/4". The little duckbill is only 1/8" ID so theres no way it's gonna go on the steel fitting and stay there. If I screw the fitting out of the tank the duckbill will stretch on, but then I can't screw it back into the tank.

All the ones that I have seen, the line just goes through the hole in the tank, no threaded fitting. The reducer holds the duckbill on mine, half in the line, half in the duckbill. I have been watching this thread because I have one that is doing the same thing, making a BIG mess!!opcorn:

 

[doggerdan1]

OK, I'm gonna try to post some close-up details of the set-up I have.

 

[doggerdan1]

Here's some pictures

Here's a couple of pictures of what this set-up looks like. I don't know id this is stock or someone has modified it or what.
Come on you Homelite guru's, help a brother out here.

This is the little metal coupler that screws into the tank, a hose goes on the other end to the crankcase. Notice how small the duckbill is compared to the threaded end.

This is what it looks like installed into tank.

That "gizmo" is something someone tried to make work,it doesn't belong there.The line just goes straight into the tank and then the little brass tube(which you don't seem to have, #40 on the parts list) is used to connect the duckbill to the pressure line.You will have to improvise a connector since I don't think the originals are available anymore.(Have you flushed out the oil tank,swishing a little fuel mix around in it?A lot of times the little lost tube shows up in the bottom of the tank,so pour the mix out carefully while watching closely.It's a little bit of nothing and easily overlooked.)
If the tube doesn't appear when you flush the tank,a good substitute(according to Modified Mark)is the hard plastic/nylon line as used for oil pressure gauges.You only need about a half inch of it.

There could be a suitable piece of tubing hiding inside an old ballpoint pen in your "junk" drawer.
