I screwed up majorly please help!

[CoreyB]

Hey I screwed up big time and was wondering if you could help.
One of the nuts inside the air filter of an 076 backed out and dropped into the cylinder (while running) and locked the motor up. I have the saw tore down but can not get the head off. Any suggestions other tricks to help out?
Please help I am sick to my stomach.
Any ideas @Deets066 , @Mastermind @MasterMech @Keith Gandy
Please tag anyone who may be able to help

Can you get the cylinder up far enough to access the wrist pin and wrist pin clips?

 

[exSW]

Can you split the case and pull the halves from the crank?

 

[Keith Gandy]

Head bolts wont come out?

Can you split the case and pull the halves from the crank?

I have never done that so I don't know. This is all above my pay grade.

 

[exSW]

Mine too,hasn't stopped me yet.

The nuts on top of the studs are off but the cylinder is not budging

 

[Keith Gandy]

Corey sounds like it galled the piston , cylinder, or rings . Probably gonna have to twist the cylinder around alil both ways while pulling up

There went my case splitting idea.

The nut has wedged and made a bur in the intake or lower transfers probably. Same thing retired the 394 I've been working on. Look for a gouge in the bottom of the intake skirt on the piston

 

[exSW]

Have you tried a brass drift through the plug hole and a light tap?
Have you pulled everything from the intake and exhaust side and looked for obstacles?

 

[huskihl]

Do the studs come out? Vise grips or heat

The studs are through the head preventing much side to side but I will try and see if that frees it.

 

[Guido Salvage]

Spray some lubricant down the plug hole and I agree, try twisting it.

I am looking for a brass bar now. And everything is off piston ring is right in between the exhaust and intake.

Will try that

Got a bunch of liquid wrench in there now.

At this point you're only looking to save the crankshaft , you can pretty much consider the cyl and piston as junk short of a miracle .

I was going to suggest some heat too and tapping thru the plug hole .

 

[Motorhead]

Take the clutch cover off, remove the starter,put a wrench on both sides of the saw and start working it back and forth.

 

[huskihl]

The nut might be wedged in the crankcase on the weights also. If the jug won't come up, try prying the piston up or down. Or try rotating the fw one way or the other while tapping the case
