7300 oiler
DIR By: Ducksnuff870

I generally run a 24" bar on my 7300. I'm only using a half of a
tank of bar oil to a tank of gas. As far as I know we have the
oiler turned up all the way. I'm not burning the bar and chain
up but it seems like a lil more bar oil wouldn't hurt. How much
bar oil are the rest of the dolmars out there using? My 036 uses
almost a full tank of bar oil to a tank of fuel.

It is likely time to rebuild your pump? The adjuster part of
your pump is made of nylon. The end of the adjusting screw wears
off with use and your oil pump volume diminishes.
When you get the O-rings and the adjuster, there is a black
adjuster (5200/5105/520) and a white one (6400/7300/7900) . I
replace the rubber hoses or tubes too while I'm in there. If you
do not have a green suction hose, it is time to change out the
hoses.
Something else I've noticed about older saws of this series is
that someone has stripped the adjust where it will turn around
and around. The adjustment range is less than one quarter turn.

One thing about this series of saws (6400, 7300, & 7900) is that
they are not known to be prolific oilers.
Some rules of thumb are to not use greater than a 28" bar
because of the oiler if you are cutting blow downs and dry wood
off the ground....
If clean green standing wood, you can sometimes get by with a
32" bar.
A 7900 has good enough power for a 32" bar but the oiler is the
limiter.
With the 7300/7900, most I've seen had a 24" bar.

Are you sure it is turned up all the way? Sounds a little like
turned down to minimum.

To adjust the oiler . . .
• Right for reduced oil supply
• Left for more oil supply
There's only 70 degrees of travel between low and high!

Something not mentioned in this thread is that the newer Oregon
EPA bars have a tiny angled oil hole in each side of the bar
that is only like 1/16" diameter.
I drill these out to 5/32".
Make sure the grooves and oil holes are free of wood chips

I'll double check the setting. I have a new stihl sprocket nose
25" bar mounted on it. I've never given any thought to the oil
holes. would smaller holes keep the saw from putting out as much
oil?

Yes, but I don't remember Sthl ES branded bars having small
oiler holes? Maybe mine are not new enough?
