- Customer complaint is that his brand new Husqvarna T540 Mark III chainsaw is locked up. Lets tear this saw down, look at the differences from the mark II and find out why its seized. #smallenginerepair

I had a 290 Stihl that lost part of the muffler- little rectangular flat piece that went back into the cylinder. Heard a strange rattle for a bit, but it ran fine. Then tried to start it, locked up tight. Gave it a shake and then it pulled over. Took the muffler off and fished it out of the cylinder- somehow no bore or piston damage. A year later, a friend was running his 290 and I heard the very same noise. Had him shut it off, fished the same piece out of the muffler, hadn’t made it into the cylinder yet.
Good job saving both those saws.
Great video Scott! I "disturbed" the metal clip reinstalling the carb on a performance build. And yes, some of those fasteners are on there freakishly tight. On the second pull it locked up. Luckily the clip was wedged in between the crank lobe and the case. No damage was done to the saw, but I sure was sweating it while I was tearing it down.
Someone can bring me a locked up saw and I'm wildly curious to explore the reason for the failure. If a saw I just worked on locks up its a very different feeling. I know you were sweatin it. Glad to hear it worked out.
Wow, great diagnosis. I have worked in quality control before. This is one of those unicorn things that happens. Nice "dream job" find, lol.
The saw was sent back to Sweden. I haven't heard their official opinion on the matter.
Great mechanic you took the time out to find a serious problem. It’s a wake up. Call for the company.😊
Thanks for watching!
Good work pal...investigating like Sherlock Holmes!
Thats the best part of this job. Thanks for watching!
Good grief! I agree on the 1 in 5000 analysis for sure! Good work and thanks for sharing!!
Thanks for watching!
Another excellent video. Thank you. 🙂
Thanks for watching!
Great job, you deserve a raise after that one. Thanks for letting us along for the ride. Pls let us know what they find out. Take care.
If I hear anything ill post an update.
Awesome clip! Using a T540XP Mark I, this definitely makes me want to hold on to that one as long as possible! Man it's tight beneath the hood on these.
Yep, a lot of stuff crammed in a small space. Thanks for watching!
I went to the factory in Jonkoping back in 05, they had a lab we went by where the guys assembling couldn't be disturbed, someone left the door open I guess :D
LOL!
This was really interesting. Hopefully this is a one-off and doesn't become a common manufacturing issue on this particular model. Thank you for sharing- looking forward to watching your other videos.
Husqvarna just called for the saw and I sent it to them. I probably won't hear back from them but at least they have the unit for examination. Thanks for watching!
Great video. Appreciate the breakdown of the Mark iii and an inside look at the new mods.
Way to stick with it till the end!
@@greentreepreservation Thanks for watching!
Buddy I just bought a mk3 to replace my mk2. I was very excited to see you tear it down I agree there are quite a few improvement. I hope you are correct with regard to the 1/5000.
Me too. Husky called for the saw so I suspect it was a rare mishap but who knows.
Scott has never even seen this model before and figures out the problem before all of Husqvarna even has a clue the saw exists lol
Thanks for watching!
Great video as always wow you sure had to dig into that one I'm like you just believe I was just a fluke
Ya I haven't heard of anyone else seeing this problem.
Curious where these saws are built?
VERY INTERESTING INSPECTION AND WHAT YOU FOUND TO BE THE ISSUE WITH THIS SAW. I AM GOING TO BUY THE NEW 540-3 SOON AND THANK YOU FOR THE VIDEO. BY THE WAY I WOULD LIKE TO KNOW WHERE YOU GOT YOUR INSPECTION CAMERA FROM AND HOW WELL YOU LIKE IT ? THANKS TOM
I bought the camera on amazon after wading through the many choices. For me it was important to have a small diameter head and a dual camera setup with the side camera. I probably paid 50-60 bux for the one you see here.
Awesome!!!
Good detective work Scott! I wonder what the tabs look like in other new saws. Are you going to look at your stock to see if any are loose?
I looked at one and the white plug holds it in place so it can't come out.
I looked T one and it can't come out with the white plastic support in front of it.
Agree, assuming the piece found in the cylinder matches the boot insert. I think that's the observation you made.
The saw has been shipped to Sweden for further investigation. If I find out anything I'll update.
@@TheGreasyShopRag If this is a reed valve saw, I would've expected this piece to get caught there, causing the saw to stop running.
Got a question for ya.. a friend gave me a echo 550 EVL chainsaw got it running but leaking too much bar oil when it’s running I can’t find no adjustment screw any help would be appreciated… keep up the good work
Thanks... I think the saw is like 35 or so years old.
Isn't that the saw with the adjustment screw in the air filter cover? Turn it counter-clockwise to decrease oil volume.
Will check it out and let you know… it sure was you the man thanks a million 👍
good video
Thanks for watching!
I have a pretty new t540 m3, can't have more then an hour or two of use and its driving me crazy. It will reliably start up from a cold start, but once warm it is a nightmare to start again. It takes a bunch of pulls, shuts off or bogs down and the issue is pretty persistent. I think Im going to have to take it in for warranty but I'm very annoyed that this new saw is this much trouble. Have you found any other m3 with this problem? Thanks for your video.
They've been pretty good saws for us. Not sure what you've got going on.
That Was a Very Perplexing Issue Maybe If They Put a Couple Barbs on That Metal Tab To Lock it In In The Boot and That White Cover They Could Solve This From Ever Occurring Again 😀 Those Saws Are New Too Me Have Not Seen One Across My Bench Yet Have Worked on a Few of The Earlier Series 😀 Pretty Powerful Saws
I'll have to look closer and see if there is (or was) a barb on that "clip".
@@TheGreasyShopRag Let Me Know It Would Be a Good Suggestion Too The Engineering Dept If Not 😀 I’m Curious Like You
Want to get one hoping kinks are out .metal inside intake ???unreal
Very interesting. Sometimes freaky stuff happens
Yep, I'm hoping this was just an assembly mistake.
Thrilling Exciting 🤔😉
I remember the spat between Elux and Husky where Elux wanted to make the small Husky saws at the Poulan factory in Ohio. That brought us missing circlips in the new at the time 385xp saw...
Great video. I have a Husky 450 Rancher, which I have only used about 2 times ever. I was looking to actually purchase one of these to replace the 450. I want to put a 12" bar on it and keep it in my truck as an emergency saw. The 450 is just entirely too large for this task. Not knowing a lot about saws, I feel Husqvarna is the right level of duty for someone who only needs a saw in a pinch. Thoughts on getting a "pro" level husky f or a premium consumer level user who MAY crank it once a year? I don't know much about chainsaws; which is why I am asking you, as a repairman.
The type of use you describe and storing it in a truck is a scenario I see often and those folks are using the battery version of this saw. You do need to keep a battery charged but you will never have a gummed up carb cuz it sat for a year. Another option I see is storing an empty gas powered saw in the cab with a can of engineered fuel in the bed. The size and ease of storage are most important when its just an emergency saw.
An Echo 2511T might not be a bad choice because of its small size.
Every time I find myself using my top handled saw when on the ground I recall the pro advice not to do it. The very design is set up for one handed use, which is more dangerous but sometimes essential in the tree. On the ground you can usually find a safer stance where a saw with widely separated handles gives better control.
What do you do with saws like this? You said the customer was getting a brand new saw, so do you rebuild and resell this?
We have to hang on to them for a period of time in case the manufacturer wants them back. After that they are "field destroyed". Thats my official answer.
@@TheGreasyShopRag So that's where all those broken down units come from that are sold on places like Ebay 🤣
@@albertkropp Not if they still have a serial number tag on them. At least with husqvarna part of the claim process is sending a pic of the unit with the serial tag removed and destroyed. I really don't think the manufactureres care what the dealer does with these units as long as they don't have to ever cover a warranty claim on a unit they already replaced.
@@TheGreasyShopRag Gotcha. I wondered why some crankcases listed on ebay had the tags removed, good to know!
Good Morning Brother 😎😀👍🏼
Good Morning!
This model came out with crankshaft stuffers?
No stuffers.
How did that come out in the first place I have just brought a mk3 and iam worried about this should I take it out
I haven't heard of any other failures and I just checked for any service bulletins. There are none. I really believe it was assembled improperly.
@@TheGreasyShopRag thanks for reply man put me at arsenal a bit it’s a fantastic chainsaw imo
Could this piece be removed completely? This is the second video i saw with this issue.
I suspect it prevents the tube from collapsing. Can you point me towards that other video please?

Reminds me of my experience with my Stihl FS38 trimmer.
One of the 2 nuts behind the air filter worked itself loose and went into the cylinder.
There is nothing really locking those nuts in place except the air filter.
Bad engineering.
I see that every so often.
this metal think stays on the black rubber(budd of) think to keep it .
Ring Gap locator dowel pin dislodged…!
How do you a little competition there in Central Florida?
I don't know what you mean.
Ohh no here we go again? The last model the dealership stop selling because every saw came back .do to flaws??.you would think they fixed this model..I bought the mk2 version and the case or seal was leaking oil..literally 2 tanks of gas and during breaking it in
Gently
am sure with that piece removed and reassembled the saw would run fine for yearrs
Thats quite possible but the husky engineers felt the rubber divider needed support.
