William Todd: This video title is a bit misleading LOL. You are replacing the sprocket
and the clutch drum unit, not the clutch, ok well actually you are
replacing half the clutch LOL.
To those having issues with using a piece of rope in the cylinder to bind
up the piston...its not an issue if you do it correctly. Doesn't matter
where the piston is when you insert the rope, just remember to leave enough
rope to be able to remove it after you finish. Best insurance on that is
to have a rope long enough to tie the other end to the chain saw handle.
Once you complete the work, and are ready to remove the rope, simply turn
the flywheel of the saw in the opposite direction to lower the piston and
be able to pull the rope back out. I've been doing this for many years and
have never had a problem, and have never had a rope get stuck in the intake
or exhaust ports.
As for which sprocket is better its just a matter of preference really.
With normal use they will work for many years without needing replaced.
Usually they fail when the chain isn't kept at its proper tension and
allowed to slip around the spurs which will eventually chip them or break
the teeth off completely. My 27 year old Echo chainsaw has never had the
sprocket replaced, as a matter of fact the saw has never been taken apart
other than to replace the chain. Still has the original 16" bar on it as
well. Under extremely heavy use the bar, and the sprocket as well as the
clutch may become worn enough to require replacing those components. The
problem is by the time that happens the saw may be so old that parts are
hard to find LOL. I've found this to be the problem with my Echo, some of
the parts are hard to find, or not even available anymore at all.
Jose Ferreira: yeah...use the string and ruin your piston/rings. what a dumb idea. do you
know some people dont know it may get caught on the ports?
oh nevermind. you just wanna sell some parts
Cheryl MacKenzie: Dear Mark,
Thank you very much for helping me rehab our chainsaw! Mystery dispelled,
nothing to get hung about.
Thomas Herbert: Dominic,, who the hell are you talking about ? the guy in video ? did you
work on your saw ?
Gregory Joy: he should have greased the sprocket bearing while he had it apart , or at
least made mention of it . I had never seen the cord trick before. It would
have good to see it actually done .
Dominic Cristante: This freaking idiot broke my chainsaw. He's such a crap bag and a child
Martin Benfield: Thanks. This was great. Best info I have gotten
willembeton: thanks for the tips !!
Waseem Asghar: thanks great job,we learn a great trick to open it.
Duramax0530: Good video but wondering if hammering on that clutch will do any damage to
the piston when it hits that stop?
wersuss: Thanks, also great site powermotors.lt/
WalshPhoto: Priceless video. Thanks
mindfreak001009: hi there, please can you tell me the advantage/disadvantage of spur and rim
sprockets, try to buy one for my father's farm in the Philippines, thank
you so much! really learned a lot!
kevin d: Excellent video, your making it look to easy. :)
byran garcia: 1. I put the string in the piston, it turned over and caught my string. 2.
string is caught in piston now. 3. now I have to either take my brand new
chainsaw apart or bring it to a shot so I can look like an idiot... oh yeah
can u take a shoe lace string out of my piston yeah thanks. worst idea to
lock the clutch up ever
William VanNess: Smart fella might tie a big knot on the end of that cord. Be pretty
irritating for that loose end to slip down that mouse-hole and disappear.
DownTownBrown71: I assume that you are now running around with just one shoe on???
wopfather2: i have a ryobi RY10521 model chainsaw, and i can't figure out how to relate
this video to removing its sprocket and clutch. On this model, the sprocket
and clutch are reversed. the sprocket is on the outside and the drum
appears to hide the clutch. even when locking the cylandar with a rope, the
sprocket sill spins freely. How do i get to the clutch to remove it from
the drive train?
Jakewick1: Is it likely that an old chainsaw's clutch cannot be replaced or removed?
Lord Vaders: i have a homelite chain saw and when i start it it runs great but as soon
as i touch it to a single peice of wood it bogs down really bad. i already
rebuilt the carburator. any think you might be able to think of? Thanks,
eReplacementParts.com: Check the spark arrestor in the muffler and make sure that it isn't
plugged. If it looks good the next thing I would look at is cylinder wear
which would lead to lack of compression. Use a compression tester to check
the cylinder compression. It should be around 110lbs. Anything less than
70lbs. would indicate a worn out cylinder and piston rings. I hope this
Don Brown: This was very well done. Thank You! I would like to find an e-how video on
how to do a basic carburetor kit. I my case a sthyl chain saw 290. I would
love to know if I'm doing it all right. I'm a video editor do you have your
own staff or could I help? See next video post.
JEREMY FOUNTAIN: always always always replace the clutch drum bearing
jon hepden: Thanks you this video was most helpfull.
gmax666: You should mention that the piston should be above the exhaust port before
you poke the rope in.
eReplacementParts.com: @Sasquatch7foot A spur sprocket will begin to develop grooves on the drive
surfaces when it is worn. A rim sprocket will develop indentations on the
surface of the drive holes. My saw is also a model 55. When I purchased it
it was also .325" pitch. I replaced the sprocket, bar, and chain and
converted it to 3/8" pitch. I run a 16" bar on it which is enough for most
jobs. It sure cuts fast with the 3/8" pitch chain! Thanks for watching,
chasesrc: Very cool trick using a screw driver & hammer. Thanks for the great video,
my clutch just burned up on Saturday!
ensen89: Right. I made a home-made clutch key. Just a piece of wood with two screws
in it. I had to built it twice, because the first version wasn't strong
enough and broke. Srewdriver didn't work. I don't like pounding on
maschines, it's better to apply "soft torque"
rehabsteven: Excellent video. My saw no longer idles, the chain moves regardless of the
throttle. Do I need a new clutch or is this likely to be a brake issue?
Joseph7296: Hi Mark--quick question..I'm new to chainsaw repair. I have a Husqvarna 353
saw and I removed the two C shaped clutch springs thinking I needed to do
this in order to replace a spur sprocket. Is there a special way to get the
springs back on to the clutch? I can't seem to do it. Great video and
thanks in advance for answering my question.
Don Baker: Excellent information useful also for Tanaka. Comment about making up a
tool with 2x1 wood about 3 feet and putting in 2 screws is the answer for
an old machine rather than the hammer and screwdrive method. Thanks
everyone for useful info Don at Buckinghamshire UK
Richie Burke: there called nuts ...lol not bolts
realman68751: These are the most informative videos I've been able to find . don't stop
posting them as I will use them then buy my parts from eparts...thank you
norman1987: Where do you buy a "piston binding tool?
MARIJAN KUČEJ: Thanks
John Flowers: can u show how to fix a throttle peddle's safety on a chainsaw
Maltinis: thx, great and informative video!
robertkathleen1: very informative..thank you
DownTownBrown71: Once you remove your drive sprocket, before installing your new part,
should you not remove and grease your roller bearings before reassembly?
Felicia Clarke: as a mechanic can you give me a tip, I changed chain,bar,sproket and clutch
on an old Dolmar 115, only problem is the clutch isn´t gripping, engine
runs okay , chain rotates but as soon as you apply pressure it stands
still. Have I got the wrong clutch or do I need to manipulate it in some
way before mounting it
Carl Pope: You just cant fix stupid so don't try!
Dominic Cristante: You can tell he is a childmalester
pwleppa: A very good video. Thank you and best regards from Finland.
popsdsr: You are good. You stay on subject and clearly give info. thanks
benlegend199: hello can you help me i have a chainsaw i have tryed everything to take off
the clutch but it wont move a bit please help
PERPARSON: as a chainsaw mechanic i can say that if the saw is allready used you will
never get the clutch off like that...the clutch have left "nut" so when the
saw is running the clutch is tightened more by itself.... piston lock and
clutch key !!!! sory for my bad english
gmax666: String is probably caught in exhaust port, pull the muffler and see if you
can remove the string.
keith byrd: Thanks
