I finally got fed up with not getting enough oil to the B/C when cutting really hard wood so i called Mike at Midwest Stihl and asked if there were any other oilers that would fit and he said no. He said I would have to build a bigger one or mod the one I have, so I started tearing it apart. He said I could trim some off the head of the adjuster so i could turn it a little further. I looked at the inner end of the adjuster and figured out where it would have to sit to give the oiler piston/rotor maximum travel, and grouond the head to that angle. I also took a couple thousandths off the inner end peg just to make sure it had all the travel it could get. Put it back together and put 200 revs on the drum by hand and the oil port/slot were full of oil!!!! It couldn't do that before!!!! Now to try it in the morning.....when people are awake.....my wife said the could hear me cutting an oak down today and she was in the house and I was out in the old quarry!!!!!! Everyone within 2 miles can tell when I am cutting!!! popcorn: The green is the part that was trimmed/ground. I used a small piece of rope in the cylinder to get the clutch off....

Wicked excellent mod...can you believe the nerve of those micro managers in government that directed manufacturers to do this?
 
Thank You!!! It feels good to be patted on the back....

If it's stock and ain't modded, it might as well be broke, so FIX it.
 
Is this not as important as I thought, or is everyone busy tearing down oilers???

:popcorn:
 
Theres a popular mod for the MS361 oiler

http://www.arboristsite.com/showthread.php?t=31559&page=2

what about lakes' oiler mod?
the oiler is a little weak on my ms361. there be a thread round here somewhere on how to swap in the parts from a 046 ho (i think) pump. i ordered them for my saw saturday, and hope to be dripping oil from the bar soon!

here be a quote from lakeside about the numbers and 'how-to' link:


Confirmed!

--------------------------------------------------------------------------------

You can just order the 460 FULL WRAP piston and adjuster screw. Not much point in getting the standard 460 parts. This upgrade applies equally to the 361 and 441 pumps.

I was going to post pics of the process, but it's exactly the same as the 066/660 upgrade I posted previously. http://www.arboristsite.com/showthread.php?t=31559

Took me all of 10 minutes including stripping down an old 460 pump with a broken casing.

Like with the 660, the piston is modified in the end cup and shoulder, and the control bolt has a greater eccentricty.

Give your dealer the following part numbers:

Entire HO 460R pump - 1128 640 3250 - $84.50


OR

Upgrade parts:

piston - 1128 647 0602 - $26.20
Control bolt - 1128 647 4803 - $3.90
 
Does this method work on a Husqvarna 372? I've never been satisfied with it's oiling capacity and have even drilled the oiling holes in the bar bigger.
 
This was done to a Stihl MS 390

Drilling out your oil port will not do much good because the port is the same diameter all the way ti the pump. This mod should work on any saw that is not already able to be adjusted all the way up. It only took about a 1/2 hour start to finish. I tried it out today and it squirts oil at a very good pace. It is kind of like having a paint sprayer.:greenchainsaw:
 
Hey, now thats an idea!!!!

:dizzy: No, I don't need to turn the oiler up all the way. I just turn it up high when felling trees because that is when i am cutting at an angle to the grain so the chain gets hotter. otherwise I turn it down a little. If the chain starts turning brown I turn it up a little until the browning goes away.
 
So what is the easiest and cheapest way to get my 044 oiler putting out at a better rate?
 
Anyone know if the HO 460R pump parts stated in Lake's threads above will retro fit into a 044 Oil pump?
 
Do you mod the gas tank smaller so you don't run out of oil too soon?

That was going to be my question.on my 357 i run out of oil at exactly the same tiime as I do with fuel.if i fill the tank to overflowing of fuel,i run out of bar oil before i run out of fuel.372 is also pretty close.
 
I finally got fed up ....

Cool idea. I don't have any problems so far but it still is a great idea.

great idea

I haven't tried it yet either but I'm hoping it works. I was going to purchase an oiler that would work for the range of work that we do. The factory oilers don't always get it done. I do think using stihl brand oil as well as their new chain w/ the holes in it helps but in some conditions it isn't enough. I have seven 440's that all run great, I was going to purchase the ho oiler for one and try it, but if it should work that's way too much cash to change all my saws to how they should have come from the factory. (99$ a piece) It may take a week or two for me to get it done but I will post the results. I looked for an aftermarket pump but I could only find the low output. I find it strange that this is a non issue to some folks.
 
my echo 450p oils good.. to the point it will run out before the gas if turned up all the way... so i fill the gas 3/4 full and fill oil all the way... in summer time i run it turned back a little so it will stay even..
i did have one 370 that someone tampered with the oiler,it flat dumped the oil when turned up to the point it would sling it off the back of the chain at the sprocket.
 
hit a bump in the road

easy way to get the clutch off? I'm assuming it's left hand thread. I'm modding one of my oldest 440's and the clutch has never been off. If I had seen first hand what the bearings and piston attachment look like I'd be more prone to try the rope in the cylinder trick. is there something more conventional?
 
Ok, found the info. an important remark about the string trick. turn the crank until the cylinder peaks and then go counterclockwise a smidge to feed in your string. I was concerned about stress due to poor alignment. I was imagining my hand on my wrench almost a foot away from the shaft w/ internal parts holding it w/ much less leverage. I was also worried about the string getting caught in a port or pinched somehow along piston- not much experience there.
Also have an impact wrench. see what happens
