Thanks, Jim, I'll dig up the IPLs and report back.

Write down the repair kit numbers and compare them?   I know the 5105 and 7900 have the same kit for the pump itself but the kit comes with two different adjusting screws. A white one for the big saws and a black one for the little saws. Even compare back with the 111/115 & 6000/6800?

I've tried to compare the black and white screws and the difference is not obvious?

Few Aussie guys on AS say they use big bars no problem and oil usage is 1 to 1.   Any alternate p/n for overseas saws?

Pn 038 245 010 replaced by 011 pump.  Anyone know the changes made to the New pump?

The rebuild kit for the two different numbers is the same.

They probably added a extra barb on the hose connection for the newer 7910  (011) pump?

I bet if you order the old number it will supersede to the new 011 number?

Yep, superseded by the 11.  Sounds like the internals are the same, maybe just the hose barb as you mentioned.  Perhaps the intake tube is shrinking/collapsing where the pump presses onto it?   since the O.D of the intake tube is supported by the relief machined into the case, the tube would want to collapse in on its I.d when the pump is screwed down???

I have a few Dolmars and the oiler is rather juicy with leaks on some of them. None are prolific oilers on the chain.

I was given a 111i all original and the 15" X .058" bar and .325 X .050 chain was the oilingest thing on the chain you ever seen. I changed the chainsaw around with a 115 closed port cylinder, a new Power Match 3/8" X .050 X 16" X 60DL bar and Stihl RS chain as well as a new 115 two shoe clutch with a wrap spring. I drilled the oil holes out to 5/32" in the Oregon bar. It is now just a regular oiler on the chain and messes up the shelf when you store it. I've never rebuilt the pump.

I started digging around and I actually have a new 9000 pump. I'll pull the clutch on my 7900 and see if they even look the same. I ordered this and a repair kit over a year ago to repair a Makita version of the 9000. I remember that the new pump did not look like the pump on the 9000, so I just used the kit and rebuilt the original pump.

The 372 clutch removal tool works perfect on the 7900

Look at the IPL's? Most of those Dolmars had the same basic oiler with only slight variation of the inlet and outlets.
I'm not sure what an IPL is.I normally don't dig to deep into saws if they need much work. Farthest I've ever been into one is when I installed a new cylinder and piston on my 036. I've never touched an oiler.

My 7300 has been used to pull a 36" bar once. My friend borrowed the saw and bar to cut up a big stump. He said he kept an oil can close by to keep oil on the chain. The guy I bought the bar from ran it on a 7900. A friend of mine has a ported 7900 we pulled a 36" bar with it on a big maple. He said the oiler did fine.
