Troubleshooting oiler

[STOVE]

Working through an 026 I picked up.

Bucked a pecan trunk today and bar sprocket seized near the end of the day.

Took the bar off and watched some oil being pumped out of the hole. From all of my reading these automatic oilers should make a mess when sitting at idle. It doesn’t make a mess, or paint a nice line when pointed at a stump

Tonight, I disassembled, cleaned a crazy amount of crud out of the case. Pulled the tank pickup hose out and blasted air through it. Seemed ok. Couldn’t get the 90 degree hose off the exit or pump.

My next thought is to check the alignment of the holes in the bar with the pump hole.

What else can I do to trouble shoot the oiler itself?

Is the pump adjustable? Small hole on the bottom of saw midway clutch side.

Depending on when it was made it can oil only when the clutch drum is turning, or it can oil all the time it is running. You likely have a later model.

No it is the plastic constant oiler, not the Pro

How can I tell the date of the saw?

Also is the oil line running to the exit hole something sold in bulk at the dealer?

Don't know about the date. The oil line has a brass insert in one end I suppose to keep it from collapsing. Dealer may stock it or can get it out of Hillsborough pretty quick.

I mean no disrespect, but is the chain slot in the bar packed with crapulance?

None taken, it was cleaned before use and during. I got it oiling today, took it all apart to access the pump and hoses, pulled the intake hose and ran air through it and blasted what looked like half a bag of potting soil out of the saw. I’m thinking the culprit was a bad connection between the hose and the little nipple thing on the automatic oiler. . Got it makeong more of a puddle this morning. Will still be keeping a close eye on it

Run a mix of 3 parts diesel or kerosene to 1 part bar oil for a tank or so.
easy way to help clean the crud out of the lines

Pardon my ignorance, but will this not hurt the bar and chain? Or do I do this with it off and just feather some throttle until it’s empty? Should I expect to see some crud coming out the exit or will it be small enough I won’t be able to see it

I think you can buy it bulk, but you only need ~3"

Pretty sure the 036 uses the same size hose and they sell an oil hose kit: hose, spring, and brass thimble/nipple for outlet. There is enough hose to do two lines.

Don't forget the spring insert or the hose will collapse/kink. You need to heat the hose to get it on the pump nipple and insert the brass thimble, the material is a very stiff plastic tubing. I've used a Bic lighter to heat it, but too much heat will make the hose too mushy. Not sure if boiling water would be better means of heating it?

Service manual mentions fabricating a pair of pliers to install the hose.



You can do either the pump end or brass insert first.

Kit part # 1124 007 1010. The hose lengths are 74 and 75mm for the 036 and 026 , respectively. IPLs do not show the spring or brass nipple.

One more thing to check, there is a tank vent just above the bar studs, if it's plugged the pump won't pump as there will be a vacuum inside the oil tank.

Awesome , thanks for the part number. I have emptied the tank and run the compressor through the vent to insure it’s working.

I and going to do the diesel and oil mix through the system.

I am glad you said the hose is stiff, I assumed it had hardened over time similar to some fuel lines
