Stihl 024 Oil Pumping

[solensjj]

How do I know that my 024 AV is pumping enough chain oil. Approximately uses 1/2 tank of quality bar oil to 1 tank of fuel.

No adjustment for oil flow on my model. Took entire pump, pickup tube and filter apart with no apparent issues. Is there a check valve in the oil system?

I have seen check valves in some of the older saws that I repaired.

If pumping with poor flow where are the typical problem areas?

The interface between the pick up flange tube and the pump inlet boss does this align properly each time the pump is set?

Does the pick up tube collaspe; looked good to me?

Thanks!

do your teeth turn brown? does it make a stripe of oil on the ground when you run it wide open and hold it 2-3 inches away?

How do I know that my 024 AV is pumping enough chain oil.

The chain is covered in oil all the way around the bar.

Approximately uses 1/2 tank of quality bar oil to 1 tank of fuel.

That could be correct if the chain is covered in oil. Many of the current oils are "thicker" and the saw will use less oil than before.

No adjustment for oil flow on my model. Took entire pump, pickup tube and filter apart with no apparent issues. Is there a check valve in the oil system?

The tank is vented. I think the vent is between the bar studs. Somebody else will hopefully be able to tell you for sure.

I have seen check valves in some of the older saws that I repaired.

Does the saw pump oil without the bar being mounted? If so check the bar oil hole for being plugged and alignment.
The gear that drives the pump gets worn out or damaged, flat spots. The spring that drives the gear could be slipping. The pump passages get plug. The pump housing gets worn out. Cracked,plugged, kinked lines.

The interface between the pick up flange tube and the pump inlet boss does this align properly each time the pump is set?

It should if not it will leak and the area will be covered with oil.

Does the pick up tube collaspe; looked good to me?

It could. It could also be plugged up or cracked.
Thanks!

As long as the bar and chain are not over heating then there is enough oil. Typical examples of over heating would be excessive chain streching, cutter discoloration, smoke, excessive wear, etc., it is similiar to the damage caused by using a dull chain and or a worn out or damaged bar.

There are lots of times that I will get 1/2 tank of oil to a tank of fuel, depends on the situation and the saw. Extra oil flying around is the same as throwing money away.

On the 024, if your bar is 18" or shorter, I would say that 1/2 tank of oil to a tank of fuel is fine. Some cutting conditions, and/or bars and chains, may need more oil. You will see a need for more oil as a hot bar or chain, the chain dragging on the bar which slows the saw down, there are other indicators that come with experience running the saw.

Hi, On the subject of the 024 AV, would anyone know what drives the bar oil pump worm gear? It seems that mine may be magnetically driven by the back of the clutch mating to a plate in contact with the gear itself. Would I be correct in that assumption? Thanks, hyper2

The clamping force of the tightened clutch is what hols the worm in place.
