Pump Trouble

ajwood

Hi guys! Found this site trying to track info on my Stihl 019Tsaw which is driving me NUTS!!! The saw has only done about 15 hrs work from new, although its now 7 years old. It refuses to pump oil to the chain. Has been to dealer who first fitted new pump,& on next visit did something to the tank vent. The only result was $250 less in my pocket. So I gave the local Husky dealer a go. He fitted a new oil pump another $212. It (stihl) pumps no oil. any help out there, or does someone need a small (expensive) boat anchor? Alan.

Hey Alan, I hope the guys that worked on your saw checked it before ot left their shop. Did you check to see if the hole in the side of the bar was plugged?

At the rate that saw is spending your money, you could have just about bought a NEW 192T.

I run the saw with the bar/chain off. Give it a few revs but nothing crazy ... see if the oil is coming out.

Like TreeD above says, what sort of idiots would give it back to you not working?

Sometimes the mechanism that drives the pump is busted too depending on the saw. This isn't rocket science, a very simple thing, sounds to me you been skun!

Could be broken lines, blocked lines, filter/pick up blocked, venting issue, hole in bar blocked, drive mechanism broken etc etc .... On the 440's often the worm drive craps out or the little steel arm that locates into the clutch drum is broken.

It sounds like your being fleeced to me, get a hold of a manual some tools and do it yourself.It's not rocket science.Look for the obvious..clean all the system first. Once you do it yourself you wont trust any one near your saws again..Good luck.

ajwood,

i have had the same experience with my 019's before (i have 3)

the problem will be one of these things.

1 - Blocked oil gallery (use air compressor to blow out)

2 - Heat affected oil feed line (they go hard and brittle replace with new about $15)

3 - Blocked oil pickup in tank (air compressor again)

4 - Oil pump incorrectly inserted (the oil pump has a groove on it's side if you dont put the groove in the right spot it doesn't match up with oil gallery)
There is a little diagram on the bottom of the saw where the pump goes in, it shows the correct way to install it.

5 - Faulty drive gear behind clutch mechanism

Number 4 is my educated guess as to what is wrong with your saw.
I made the same mistake when i put an oil pump in my 019 once, very frustrating.
What is worse is that you just about have to completely dismantle the saw to correct the problem.


I have had my 019's apart so many times i can just about strip one down blindfolded.They are a good little saw if you maintain them often enough.
Feel free to ask for more advice if you need help.

Thanx guys!! Lots of good suggestions there.Except the do it yourself. I hate working on small engine stuff. Give me a bulldozer or big Cummins,& I can just go for it. Alan.

Howdy Alan,

I love the small stuff these days.
I grew up in a remote mining town, when i left school i got an apprenticeship as a diesel mechanic.
I spent years crawling around in Cat dozers, Terex dump trucks etc...

I hated it, hard back breaking work, getting filthy dirty and skinning your knuckles.

Thats why i love the tree industry so much, instead of that crap you get to do hard back breaking work, you get filthy dirty and you skin your knuckles.

Hi. Flyn!! I can relate to that!!But I enjoy watching someone else working on small stuff. Alan.

G'day ajwood,
Its sometimes worth having a go yourself. Then you know your way around the saw when other stuff goes belly up.
If you need some exploded diagrams for that saw PM me.
Cheers

Shaggs, that is extremely useful advice. Your a good guy for pointing out the fact that it CAN be done by a DIY.

I live 120 miles (210 km) from my nearest saw dealer, its NOT an option to take everything to the dealer. With digital cameras and recorders, its NOT difficult to sequence photos to be able to re-assemble the machine.

For the folks that have never done this kind of thing before, it GIVES you a warm and fuzzy feeling of accomplishment when you suceed!

Even if you don't manage to fix it yourself, you will have an appreciation for the people you do that sort of work every day.

Just use the grey matter, and MOST importantly, DON"T LOSE ANY PARTS!
