Stihl TS 420 Concrete Saw ran without Oil - full Teardown

- Опубликовано: 6 дек 2024
- Stihl TS 420 concrete saw ran WITHOUT OIL and thats why we disassemble it completely. It was runnig for about 2 hours until it suddenly stopped and the puller rope feels like the piston is stuck.
We start to take the clutch cover off. Next is the big front part where the cutting disk sits in. To take the big handel off its a few screws and springs, then we can pull it apart. Afterwards many screws which hold the covers and so on need to go. The air filter cover and some other plastic stuff like the handle can be removed. So we work ourselves further into the machine until we reach the cylinder and carburetor. To take the carburattor out I figure out its the easiest to take the two main parts with the gas tank and the cylinder apart. To do so we have to remove some hoses and screws. Then the two big parts come apart and we can finally disassemble the cylinder, piston and crankshaft. To take the crankshaft out and split the crank cases we have to remove the clutch and flywheel. With some heating action and hammer motivation the cases come apart and we can remove the crank shaft.
Because I want to make sure that the fuel air mixture is right when all parts are new we also disassemble the carbs to check the gaskets and membranes inside.
Finally with all parts seperated on the bench we have a look at all of them to see what needs to be ordered and replaced.
Do you enjoy my video? Because thats my intention! Thank you for watching.
I am very happy if you subscribe and answer all comments with great joy.
What do you think about the questions at the end? Yes? no? Stop talking bikedogtor and keep wrenching? And Why is there so much water where a street is supposed to be?
I'm a brick mason in the United States. I absolutely love the stihl ts420. Its handled all my temper tantrums as an apprentice being thrown around and stuff. Now that I have my own it was nice to see someone take it apart so I have an idea of whats going on. Great video!
Thanks for your comment, very good to read your nice words.
Thanks for the strip down tutorial 👍I will just say that after a top end seizure the crank and bearings tend to be ok and do not need replacing! 👍
That was a great tear-down with good explanations, thank you.
Now show us the re-build and how it runs!
Thank you. You find those videos on my channel :-)
I really enjoy your videos. You walk us through every step. I have learned a lot from your videos. Thank you
Thanks for your comment
I am a stihl tech if you put a aftermarket piston and cylinder on get a good 1 some have a problem of the coting coming off the cylinder and then it will not last long
I found Muscle-Milk-KTM's comments to be the most helpful and accurate instructions. I would only add for cleaning that you can use de-greaser and a pressure cleaner to blast off most of the concrete dust and muck on the parts. Easier when disassembled. Use only about 1.5 - 2 K psi with a fan spray tip. Be careful never to point it into your exhaust, carby inlet or crank-case. If you accidentally did, shake out the water and blow out with compressed air. Spray some water dispersant into the crankcase if it was affected. once all the parts are clean, leave them in the Sun for about 1-2 hours which will dry the machine out enough to use. Same can be done even when machine is assembled. Just shake all the water out and blow with compressed air afterwards.
Thank you for your comment. Every comment like yours help others do the work
I would like to see how you cleaned everything . I myself like to take old things and rebuild them so it always nice to see different methods of cleaning
Hey, there is one video of the series where I clean all parts. But I use a environmental friendly degreaser and water.
Why do you have to replace the crank
Enjoyed the video and the throttle assembly helped me. Thanks
Thank you
Really nice video sir, i always wanted to know how this machine worked. you made my day. thank you very much, and i would really like to see you rebuild it.
Thank you! Assembly video is in the making but not so much time atm. Regards
For your concrete dirt, a heavy degreaser is the best route IMO. Spray it on, let it soak for 10-15 mins then wipe/blow it off.
Before you take off the cylinder either use a cylinder stop for the purpose or put rope in the cylinder through the spark plug hole for the piston to bottom out against to remove the nuts on the crankshaft rather than clamping it in a vice.
Thanks I will definitely do that next time
Yes I want to see rebuild.
Safety shoes made me laugh.
I think they're all T27, not T25
It's really close... I was using a T25 for while at first too..
Also, I really think you can use a power washer to clean it off at first.
Or just a garden hose spray.
Maybe take ignition coil off first.
Let it all dry off.
Maybe not?
It’s 60 in parts I just did it still running 6 months later piston cylinder kit
Yes show the lot Fritz!
Ehmm what? 😄
Very interesting
Hi how can I find a brand new cylinder kit on the aftermarket place? I have a ts500i with the same exact problem. Can you refere to a homepage or website maybe?
Just whatever shop you find on Google. I think dealers sell original parts as well
There is a bagfel under the flywheel
Where is the best place to order replacement parts?
I ordered from a German shop. I guess this doesn't help?
I like your flip flops
Not for sale sry 😝
Show the entire video its good what you do! Were the parts expensive in the petrol cutter teardown??
Thanks, I decided to show it all and you find the videos on my channel. Parts were around 150€ but from China ;-)
You better presher test the saw after you put it together
Do the main bearings have any play?
The old or new ones?
Subscribed love the content
Hey man appreciate you please do a rebuilt video no need for time laps would be better if you explain with some tips
Thank you, I decided to upload the rebuild videos and a time lapse. To be found on my channel.
Also wenn ich an Timelapse denke, dann verstehe ich darunter diese unkommentierten Zusammenschnitte (siehe: "Restoring an old XYZ from 19xx")...
Ist zwar auch entspannt/interessant, finde aber deine Kommentare/Erklärungen nebenher immer ganz witzig und hilfreich. Kann auch sein, dass ich die Minderheit bin, muss ja n' Grund haben warum es so viele ASMR-Style Schrauber Videos gibt ¯\_(ツ)_/¯
Ja so in der Art habe ich bisher kein Video gemacht aber es scheint ja gefragt zu sein. In dem Fall alle Teile schneller abgespielt zusammen geschnitten mit Musik hinterlegt. Danke für deine Antwort dazu.
youtube sucks now but videos like this are why I still check it out! thanks!
Do you have a link for the parts of the parts you used?
Most of them were ordered at hsparts.de
Hi where about is your shop ?
In Germany
Brilliant video the best I have seen yet and I have watched all of them so very well done and I’d love to see the full rebuild mate👍
Thank you! Full rebuild time lapse is on my channel
Much easier way of removing flywheel than using a vice!!!
Yea I didn't know.
i heard you say T-25, but I think stihl uses T-27 across all power tools
Hmm can't look it up now, maybe you are right.
Mess the crsnk shaft
You don't need to do that plus you should have left the cylinder on and use a rope to hold the cylinder
Get a gasket set
Thanks for your comments. Next time I will do better.
For fuck sake man build a flywheel puller
In deutsch wäre es hilfreicher
Ok
Goofy jobs Hajahahahaha not Show run hahahajaja
