$9 echo at goodwill. Why lol

Flywheel off

 

[August76]

I should probably look for a service manual. Can't get clutch off so far. And the clam crap is undone on bottom of plastic. I think probably removing the anti vibe is called for?

 

[Bob Hedgecutter]

Are Echo crank stems like Husqvarna ones- can you grease the needle bearing through the hole in the crank stem?
I would be WD40ing or similar- that grease channel and thread to clutch spider, let it sit a bit, blast it some more- maybe apply a bit of heat and after locking the piston, try removal again.

Use too much force- or too much leverage and you might just shear the crank tail off and ruin a sound $9 investment here.

Or PB Blaster rather than wd40...
Then, either buy an Echo clutch removal socket or make your own out of a large enough socket and a cut-off wheel.

Yeah- whatever is your penetrant of choice- cant say I have ever seen the PB Blaster on shelves over here- we are more of a CRC556 nation.

Ha, probably the same basic stuff with a different label

Fill as much acetone and auto trans fluid as you can then give it a few hits with the impact gun use common sense with the impact.

Using a wooden dowel and smaller hammer can dislodge it enough to break initial seal and let your oil work around the rings.
Not such a flash idea if using a steel punch, the piston is at TDC or BDC and or the crank bearings are frozen completely solid.
But for a $9 investment- not a lot to loose.

It's bad lol. Crank bearings were frozen. I was able to get them moving freely lol. Piston is still stuck. Soaking from bottom with mineral spirits.

 

[August76]

The clutch came off with a few good wacks and a punch on the arm part. No damage done. Needles fell about. But should be easy to stick back with Grease.
The rust us pretty bad. At this point I'm not sure if these crank bearings would last long if this thing ever runs again lol.
So for now this is where I am. Stuck piston soaking from bottom with dirty mineral spirits. Scraped off as much rust as possible. Worked crank back and forth till it turned easy. Wrist pin is good. Corrosion on bottom of piston .

 

[Bob Hedgecutter]

Worst case scenario- ring contact has corroded through the cylinder coating and chunks of it are going to come away with the rings.

Now is the time for some gentle heat on the cylinder.

I'm in Arizona...lol I just left it outside hoping it would heat up. Maybe tomorrow I'll use some heat.

 

[mountainlake]

This is what I'd do

Looks like the same style motor as the BG86 blowers I'm working on.

 

[ladnar]

I like Echo and I like this thread, I will be watching!

 

[August76]

Ok finally got piston out. Looks awful. Possibly straight gassed or damaged from my removal

 

[August76]

After a soak

 

[August76]

Broken piston ring too lol. And spring comes off crank seal and bearing seazed too.must have been in some Texas flood or something. I've never seen one like this.

 

[Philbert]

Personally, I wouldn’t pay more than $9 for that saw!

This saw is starting to realise its ticket value!
