Stihl 044 Crank seal (oiler side)

[SawmillMan]

I have an 044 and need to replace the crank seal on the oiler/clutch side. I'm not sure how to access the seal. What is necessary to remove the oiler mechanism restricting access to the seal? I successfully changed the flywheel side seal. At this point I've only removed the sprocket and clutch and I'm unsure what to do next.

All of it... brake cover, brake band, oiler, bearing spacer. Give her a good cleaning while you're in there.

Take some good pictures of how the chain brake mechanism looks before you take it apart. In my opinion, how it goes together is not intuitive at all.

Only the band needs to be removed, the rest can stay in the saw.

Should the spacer be installed before or after the seal? I assume beforehand.

All, thanks for the input. Seals successfully installed and the saw runs like new (new jug and piston), it almost is.

It seems to leak a bit more oil than I recall when it is shut off after running. Do you suppose the O-ring on the oil pump is faulty?

Put dye into the oil. Make it real colorful. Run the saw a tiny bit and look under the cover, under the clutch, etc. This will help find where the leak is located. Mike

Is this after running it not in the wood?

Yes.

Indeed, sometimes when you uninstall and reinstall the oiler, the seal can leak..... they get stiff and once you unseat them.... well, you know. Hey, at least you know how to get in there and do it. Prolly six or ten bucks for the hose... the screen is reusable, provided I'm keeping my saws straight.

That reminds me. There is a little fat "o" ring at the top and easy to loose. It is straight above the oil hose and in the crank case. There is a depressed area for it to fit. Maybe lost it? Mike

Yes.

In that case, what you're experiencing is totally normal.

It was reinstalled, but I was suspect of its reliability. It was a hard booger to get seated.
