in part 2 i am gona go over failure causes and talk about mixing oils and carbon build up.....i honestly think a flake of carbon dislodged from the top of the cylinder or exhaust port and got lodged between the piston and one of the ports...but the main cause was dirt injestion
2:50.. got that right.. im rebuilding one because of user error.. these engines used mixed gas only. Air filter that came out of company saw was ridiculous and suprising that the saw still runs flawlessly
IF YOU ARE REBUILDING THE ENGINE THEN YOU WOULD RELACE THE BEARINGS, ELIMINATING THE NEED TO GUESS HOW MUCH PLAY IS TOO MUCH PLAY.....THEY ARE EASY TO REPLACE...JUST POP THE KEEPER OUT OF THE PISTON AND SLIDE OUT THE WRIST PIN AND INSTALL THE NEW BEARING
Yeah I got a question. I seem to see a lot of these 420 tearing up the Pistons is a pin locator coming out of the Piston that holds the ring from spinning . Then getting caught in the port and breaking the ring I believe that's what we're looking at here
Hi mowermedic1, if it's noticed that compression is weakening would it probably be due to worn rings and would it be good practice to renew at this point and avert total engine failure
?? I have a TS420 also but it’s one without the DECO Valve. I would like to do a top rebuild as well can I switch the housing to a one with the DECO valve and change the shroud to fit?
hey jeremy great videos. i am attempting to rebuild my TS420. I have about a 1/4" horizontal play with my connecting rod, is that normal, or okay to put a new piston and cylinder on? another video that i watched said that there should be no movement on the crankshaft rod, and if there is then that can cause the piston to rub more on one side of the cylinder causing it to burn out faster. i dont want to replace crankshaft obviously. i tried and having a hard time getting that out. suggestions??
Laughed my arse off when you turned that machine up side down & spilt fuel everywhere. I do the same damn thing! I hate these machines - sorry sthil fans these saws are garbage. Find an old TS400 and keep it well maintained.

Great nice to video on this type of saw
i will explain the symtoms in part 2 ;) dont wana spoil it

Thank you bro

Do you think the piston just broke on its own or was there too much carbon in the exhaust port that took out the piston ring ?

Hi do you know if the crankshaft for the stihl ts420 works on the ts 480
I would need the serial numbers
Is this one 00009673436AED
It’s located in the bottom area

connecting rod bearings are not replaceable.......you should have some horizontal movement but not any vertical
How the heck do you replace the throttle control button
what r the symptoms of a blown top end?
I like the way u think
nice
I put a new head on but mine didn't have two hole's at spark plug hole now what do I do.
soon.....very soon ;)
i sub,recommended by donyboy.
i screwed up one of my chinese engines by using rings that had too small of a gap. i am just gonna run it till it dies.
what about that 5hp
kk
