Homelite SXL oiler output

[ChuckinOhio]

Gentlemen,

My SXL-925 is just plain hosin the bar oil while it is running, a problem that I have not had previously.

I installed a new GB 24" bar on it, hit the manual oiler several times while rotating the chain by hand to grease er up, pulled the rip cord and she is a drippy mess. Stopped the saw cleaned it up and tried again, still spewin like a radio talk show host.

Is it possible that by hitting the manual oiler several times I just loaded up the oiling system and it will work its way out of it, or is there another underlying problem?

I also noticed bar oil seemed to be leaking from the filler cap like perhaps the tank was being pressurized??? Cleaned the vents in cap, and blew it out and seems to be OK as far as venting. Is my tank pressurizing from the crankcase?

Chuck, I dont think its possable for the crank pressure to get into the oil tank on this saw due to there being and "Air gap" between the tanks and the crancase.

Their is one place that could crack and cause this, but that is a remote possability.


The oil is coming off of the chain correct? Ive put on bar plates incorrectly before resulting in an incomplete seal that resulted in the oil flowing out of the bottom of the saw at a good rate.


Try and run it some and see what happens, if it dosent quit we can try and think on this further.

Bar plates are in correctly

The oil is coming off of the chain definitely. I fired it up, let it warm up and after a few minutes of running the first 14 inches or so of the bar was dripping oil from the top and off of the bottom of the chain.
I had forgotten about that air gap, actually read several times in old posts about overheating SXL's, and completely dropped the ball there!
I did not get to run it again, only to fire up briefly this evening to check things out, and it seemed to be a bit less,so perhaps it is because of me hitting the manual oiler when I put the new B&C on. I think that somehow I had the oiling system loaded up and it was gooshing like all get out. Bar rails all full of oil, system pumped up or something like that.
I never have done that before, but it seemed like a good idea to prelube everything. Thats what I get for thinking. Bet I dont do that anymore!!
Thanks for the input Wolves, I might have to junk mine and buy one of yours!

Its not a bad idea at all Chuck, and a method that I also use. As far as the air gap, I couldnt figure if this would play into it either, so I went and looked at a saw thats dissaembled in a box.


Untill I bought this saw I had only an idea that an air gap was a good idea as its covered on both sides.



Let me know what you find, theres check balls and such that may be able to cause something like this to happen, but I cant say for sure without some dissasembly and digging.

This is really puzzleing. I mean, first of all, from the best I can tell, the manual oiler and auto oiler on these saws are pretty much independant. I can't comprehend any way for a pressure to be building in the oil reservoir unless possibly the check valve on the manual oiler is acting in reverse somehow and causing the pumps to push pressure into the tank rather than sucking out of it. It may be worthwhile to remove the manual oiler system and see if its pumping properly (sucking at the upper inlet, pushing at the lower). Also, I can't imagine how the auto oiler would somehow wear and actually increase oil flow. If anything, wear here will decrease oil output. Again, I'd suggest trying to independantly test the manual circuit alone by removal and at least see if its working as expected.

I am a ham hand

Well I went back to square one, and here is what I found out.

I removed the B&C,completely defunkified it and cleaned the saw thoroughly.
Reinstalled the B&C, lit er off, and everything appears normal.
Removed B&C again, thoroughly cleaned, reinstalled and hit manual oiler 3 times while rotating by hand to pre lube, and got a little bit o splooge but nothing like the previously drippy mess. Acceptable in my book.
Removed once again, cleaned and reinstalled, hit the manual oiler while rotating by hand till chain appeared to be good and oiled. This entailed 7 to 8 pumps on the manual oiler. Lit the old girl up and there was the drips. It appeared that I loaded the bar grooves up with oil pretty good in addition to the oiler slot in the case,sprocket,gap in between bar plates etc. and it's gotta go somewhere ya know!!

As far as my oil tank seeming like it was pressurized, that still has me puzzled. It is not oozing like it was and appears to be normal. All I can come up with is perhaps I had the cap gooped up with bar oil, vent hole and all, and seeing as it is in the teens here as far as temperature it was pretty thick and sticky. Saw warms up, oil thins a bit and oozes out of cap and off of cap gasket!

I think that if I pre lube a tad less exhuberantly, I will be okay. thanks for the time you fellas took to chip in on this, it is appreciated.
