266 oiling out the clutch cover

[David B]

@Spike60 can you comment on the 162 vent?

162 on right. Very small oil fill. Cap I found in my parts stash doesn't fit by just a hair. 

 I will try to tuck the vent line rearward on the 266, I have forceps.

@Spike60 can you comment on the 162 vent?

You already nailed it; vented oil cap.

Now I need to find one as this set of cases is useless without it.

So I can better understand this oil tank vent system.  The 266 that DavidB photographed and is working on has an oil tank vent hole near the bar mount studs.  Attracted to this hole is a hose/straw about 4" long.  This hose just sticks up toward the oil fill cap and toward the top of the oil tank.  Nothing inside the oil tank holds the hose/straw in place?  No one way check valve on the hose?   The other earlier model 266 that I photographed has a oil tank vent near the oil fill cap at the top of the oil tank.  Looks like a porous brass filter.  So if these are the two style of oil vent used on the 266, why the need for/or remarks about a vented oil cap?  Am I missing something.  And if I'm understanding this the model 61 should have the oil tank vent like DavidB has on his 266.

Well I looked at a 61 and a 261.  I should have looked at these first.  I just looked at my 266 thinking the photos from that would be helpful.  The oil vent hose is stiff like a straw, not very flexible at all.  It connects to the vent hole near the bar mount studs inside the oil tank.  Just press fit into the hole.  The other end is put above the oil cap hole.  At about the 1:00 o'clock position.  This area traps that end of the hose at the very top of the oil tank.

Yep. I have mine bent around towards the front of the saw now. Not sure that’s right. 

I filled the oil res up just to the cap opening, covering the oil pickup but not up to the vent hose port. Ran the saw no bar n chain and oil only came out the oil channel. I need to try it with more oil. Had to go do a roadside rescue tonight. 

The early 162 vents through a smaller cap.

I'll post the part number later this morning, but those vented caps are NLA from Husky. And I'd be surprised if there are any aftermarket alternatives. Be careful buying stuff from the e-bay'ers.

OK, story time. Ain't this the most fun Husky/Jonsered chassis? Not saying it's the best, but over the years I've grabbed these saws far more than the 372/2171 that replaced them. The fun part comes from sorting out these variations on the projects, or even creating your own. 61 white top with 266 P&C, 266 with 272 kit. Thought Jonsered should have had a 52mm version and corrected that injustice by putting a 272 kit on a 625 to create the should-have-been "672".

Have a 266 in the shop right now I'm nursing back to life. Had been running a flock filter, minus the flock. Absolutely nothing more than a window screen. Customer let his son take this, along with a 254 and 372XT to a local small engine course the county puts on. The list of errors was a long one. The 254 had no clutch spring. I know both father and son, so I'll find this kid a couple projects to mess with so he doesn't have to experiment on his Pop's saws.

Why was it only leaking when the saw was running?  I would think tank oil level would have also affected the leak from the vent hole.

Part number for that cap is 501 564 101

@DHansen I need to retest full of oil.

@Spike60  good stuff...I think I've mentioned the 272 I'm going to build...should be a nice, fun, little different saw.

I will say my ported 2166 stomps a hole in my 266...which is the reason for the 272 build.
