How to fix the most common cause of a bar oil leak on a Stihl chainsaw. I tear down my Stihl MS362 to show you chain sprocket removal, clutch removal, bar oil pump removal and cleaning. The cause is often the oil pump seals/gaskets, I show you how to clean or replace them.

Thanks for not wasting time with silly stories and unnecessary filler! I wonder how similar this job would be for my lil ol ms170.
You’re welcome. Yes it’s the same procedure to remove the clutch and get to the oil pump. Replace the oil pump seal and oil transfer tube.
@@TheLawnEngineer ok, thanx for the quick response!
@@thechronic555 you’re welcome
Great job and good detail, comments are just right. I reviewed a few other vids before finding yours, unfortunately. YOURS is the best! I needed to see EXACTLY how to torque on the 3/4" clutch nut and HOW to stop the pistion(rope!, no need for Stihl's special stop tool). No one else explained this. I feel I can NOW be successful stopping the piston. Thanks!
I’m glad you found some value in my video 👍. I have nothing but to sell, so I’m trying to give the best practical advice possible.
Awesome. I pulled the clutch off mine yesterday and it was super oily. I didn’t know where to go from there, but now I do. Thanks!
You’re welcome 👍
Dude thank you so much for making this video I hate my house with wood and my Saw's been down for the last 3 weeks trying to figure out how to get it Loose without taking it to a dealer
Glad I was able to help, thanks for checking in.
Great video. Easy to understand. Thanks!!
Glad it was helpful!
Great job mate, thank you for sharing…
You’re welcome.
Saw arrived yesterday th-cam.com/users/postUgkxfQm1wmg0ItKDLavxj1nXtQY9HP7EF504 and today I cut about 3/4 cord of wood with it. Make sure you get an extension chord that is at least 12 gauge wire, minimum. This is my first electric in about 10 years, and things sure have improved. The self-sharpener works great, and it just kept cutting through some pretty decent logs. Wear your eye protection, and ear protection. Excellent saw.
Thank you 👍
So helpful! Thanks!
Glad it was helpful!
nice and thorough thank you
You’re welcome, thanks for checking in
Thanks 4 showing
You're welcome. I have a new and improved video here: th-cam.com/video/TQjw_NvpWSs/w-d-xo.html
You should put a little grease on that roller bearing, it will last a lot longer.😊
Great point! I have a newer and better video here: How to fix a bar oil leak on a Stihl chainsaw

Thanks for doing the video. Mine leaks all over the side where you adjust the chain. I dint think I've taken the clutch off etc for a clea. The rest of machine is constantly kept clean though. :-)
You're welcome. I should have reinforced replacing the oil pump seals in the video especially if you have a significant leak.
Good job on keeping your machine clean!
@@TheLawnEngineer ☺️👍🏼. Do you think it could possible be the oil pump seals? Thanks so much 👍🏼
@@D992 Yes, if you clean by the oil pump and replace those oil pump seals it should take care of your problem.
@@TheLawnEngineer Thank you :-)
Would suggest with light air pressure to blow out oil passages after removing pump, suction port back into the oil tank & out the discharge oil passage to the bar.Cheers
Great additions, thanks for taking time to share.
Thank you this really helps. At 7:25 you say, 'I believe I have a situation where there is dirt in there, are you referring to the seals? My oiler isnt working and it sounds like I should check the plastic gear, clean those seals, check any rubber hoses in there (its a 261) and also clean out the oiler with a solvent that evaporates cleanly. I dont think its the oil filter and everything relevant to flow at the bar is fine.
Yes, exactly dirt in the seals. Since making the video, I have evolved my understanding. You should replace the seal and pickup tube. Either it’s low quality rubber or something in the bar oil is causing these seals to degrade faster than normal.
@@TheLawnEngineer Very interesting, this has all been really helpful, its my first time going through the oil systems on my two saws.
@@followtheciaence you’re welcome.
Okay I found a cool purple rope here because I have two daughters 😂😂😂 made me laugh
I’m glad that one landed for you 🙃
But did you actually find the leak or fix anything or did you just clean stuff up that might be interrupting the seals?
Cleaning up the seals and reinstalling stopped the leak but I should have reinforced replacing them. I have plans to make a new video in which I replace them.
@@TheLawnEngineer - If you make a new video, it would be nice to show how the oil comes out of the saw body and into the blade. Any seals there? Any passageways, holes, or seals that should be cleaned or verified free of debris? Maybe even show the tube from the oil reservoir. In other words, a complete tutorial and how to on assessing and repairing the chain oil assembly from reservoir to chain!
We'll done video! My problem is over lubrication when the saw is running. This may be due to dirty pump assembly? I'll disassemble and explore!
I would replace the oil pump assembly while you are in there. I have a new video on this coming soon.
First things first. You need a Torx set to work on these. I only got so far but I need to get torx to go all the way. My stihl guy said it’s normal for these to leak a little out the bottom bc the vacuum and everything are always full and run out when it’s not being used
Good additions, thanks for sharing.
What did you use to clean the parts and compartment?
I used WD-40. I should have reinforced replacing the oil pump seals more, I’d strongly recommend since you are already in there.
I did watch another youtube video in which he put the rope in the cylinder to lock up the piston, and it got into the exhaust valve, which cut off a piece of the rope. And so the problem got compounded because the exhaust channel now had a short piece of rope in it necessitating the removal of the muffler and fishing out the piece of rope (which he didn't show),
Yes, that is rare. It possible. Updated video here:

2 strokes don’t have exhaust valves lol
Would this be the cause of an oil leak on my ms381?
Leaks oil into the storage case when not in use
Yes, that’s exactly what happens. I have a newer/better video here: How to fix a bar oil leak on a Stihl chainsaw
th-cam.com/video/TQjw_NvpWSs/w-d-xo.html
You are always going to have oil in saw case. There is oil in the bar groove and oil thrown up into the sprocket area etc. when you let the saw gravity will have all of that oil running down, you can’t stop gravity. Kind of like hanging an oil soaked rag from a nail, come back later and there will be oil on the floor.
Did you not replace the seal? I’m curious it doesn’t look as though you’re actually fixed anything sorry just my old opinion thanks though.
The seal and pickup tube should absolutely be replaced. I’ve been meaning to make a new/better video. I have more experience now with videos and I honestly didn’t think many people would watch this one.
The washer behind the clutch is a slinger washer. It keeps all that crap you are blowing out from getting into the clutch
Thanks for checking in. Slinger washer, good to know 👍
@@TheLawnEngineer That`s NOT what that washers intended purpose is. If it were, then why is the washer so much smaller than the clutch. Think about that for a minute.
Sooo what happens if some of the rope ripped off. Inside
I guess that depends on how much. A small amount would burn up and be pushed out the exhaust.
@@TheLawnEngineer I got it out through the muffler. Lol
The easiet way to remove the clutch nut is with an impact. Just leave the spark plug installed. So where was the leak coming from?
Good tip, I'll point that out as an option next time. It was leaking from the oil pump seals. I have to redo this video and made that more clear.
Thanks for checking in.
@@TheLawnEngineer What oil pump seal are you referring to? Do you mean where the pickup hose exits the tank and seals to the pump?
@@akquicksilver Yes.
IT would have been good to make sure the clutch bearing is clean and sufficiently greased.
Very good add. I've been thinking about doing an updated video and I'll make sure to include that on the new video.
The chain brake handle could easily at the factory be designed to hold chain lube oil , with a manual off/ on tap relying on gravity to drop oil onto the saw chain .
You are correct. Although there seems to be many more issue’s recently. I wonder if Bar and Chain oil manufacturers are using ethanol in some way and it’s breaking down the rubber components.
Unfortunately, that would not work at all because often the chainsaw is turned on its side to make the felling cuts, limbing, etc. Gravity would not help you then and oil viscosity changes with temperature. Would be great if it were simpler.
@@scottjefferson6984 perhaps a small worm drive or gear driven low pressure oil pump to oil the bar and chain, I remember my '58 thunderbird ( motorbike) had a matchbox size piston oil pump .🏖️✨🌲🌅👍
Helpful video but you are sometimes casting shadows on what you are trying to show us. Also, in some of the shots all we can see is the back of your hand. Thanks for the content
Thanks for checking in. I agree with your feedback, I'm slowly getting better at this video thing. I am actually working on a replacement video for this one.
5:00 "Reverse" thread? Its called LHT, or simply left-handed thread. Take your left hand, point that hand's thumb in the direction you desire the nut to move & turn nut in the direction the fingers point. 👈
The terms are used interchangeably, but yes left hand thread is the official term.
I think you C clip is actually called an E clip due to its being shaped like an E. And no grease/lube on the needle bearing??
Yes I agree...E clip and grease should be added to the needle bearing. I'm working on an updated video.
I have a farm boss leaking. Just picked it up from the shop and told them it was leaking. They said they let it sit overnight and it wasn't leaking so they just did a tune up i requested. I start it up once i get home and it started leaking 😂 WTF
That’s about right. I am a pretty big stihl fan but something is going on with bar oil leaking…maybe they changed suppliers of the rubber seals?
Called left-handed thread!
I need to redo this video. It was done very early in my video days and it could be better in a lot of ways. Things you know seem to escape you when the camera is rolling until you get use to it.
If only they made oil caps that don’t leak on a brand new saw
Yes, I need to include the caps in a future video 👍
