Stihl 044

[Madsaw]

Hi All
Just picked up a stihl 044 the other day. Well today was the first i got to play with it. Well one the oiler is a no go. After running it it will seep oil out of the port on the side of the saw.It will not pump none. So , I take the clutch drum off and the plastic cover around there to see what I can see. Well the area in the is oily. Also how much play should be seen or felt on the end of the crank on the clutch side. I pulled the cover off the other sdied and the tryed to move the crank it was tight, but ti seemed the key was loose on the flywheel but the nut was tight.
To me I am thinking the clutch side bearing is going bad and toke the oil pump with it. Any idea on cost to fix it.
Maybe should just sell it. Runs good and strong piston is good yet. But seems a little hard to start when cold soem times. This is my first sthil though will take some time getting used too.
Later
Bob

Crank does not directly drive the oil pump on an 044. The oil pump just happens to mount around the crank. It's like this: Crank turns the clutch, clutch engages the drum, drum has a notch on its edge whichs drives a long tang attached to a worm which drives the oil pump. The only way for the crank to take out the oil pump is for the bearing to grenade and then have the crank come crashing into the pump. I have seen where the drum has gotten too loose on the crank end, from a wore sprocket bearing or wore drum, and rub into the pump. Check for that.

For bearing play, the best way to eyeball any play, for me anyways, is to strip the saw down to the crank seals and and try to wiggle the crank ends, watching for any movement at the oil seal-crank shaft interface. It's hillbilly, I know, but it works.

BTW, for a non-oiling pump, check that long tang driving the oil pump. It could be broke or spinning loose on the worm.

Good luck, Chris B.

If its not oiling,
it could be an oil pickup line disconnected somewhere, or maybe a broken line, or possibly a kink in it, which isnt too hard to fix.

While you're looking at those parts, check the oil pickup filter in the tank too, it may need to be replaced.

pump

Check the crank play, there should not be any.
As for the pump, a bad crank will take out the pump. The extra play will put too much pressure on the pump piston, which will breal the tang off the piston, causing it to bind and not pump. I started stocking pump pistons for this reason. Check all the other things mentioned before, they all pertain to the same problem.

Stihltech,

Good point, never thought of that. The worm does have a fairly snug fit between the pump body and the crank. This is why I always look forward to your diagnosis.

Madsaw,

Check that circlip holding the drum assembly on. Mine came off of my 066 yesterday and just about grenaded everything under the bar cover. Sprocket bearing is gone, clip, washer. The drum got loose enough on the shaft after the bearing disappeared that it wore into the oil pump a ways and broke a clutch spring. As it was, the drum wedged into the brake band and stalled out the engine. Thank god for that. My own dumb fault. I knew the clip was a little loose, but had no idea what it could do.

Off to the dealer for parts. He loves me. I may be his number 1 Stihl customer.
