036 Pro won't hold vacuum?

[HarleyT]

So you fixed the saw once after the circlip failure? What caused the second failure?

 

[HarleyT]

If that is the case, describe that failure.

That seems to be the story...so far. I am wondering if my base gasket is not sealed up tight? I just hand tightened bolts to base, wondering if the used cylinder has a small flaw. This saw rerunning prior to cir clip release in old cylinder.

So does it pass pres and not vac or what stoolie?

When I took the cylinder/piston off the saw it showed no issues other than where the clip ripped up the cylinder/piston.

I am confused i thought the post was about Vac? Its apart now what?

We are not trying to beat up on you, but trying to visualize what you have.

I am confused is it apart or is it failing vac?

An 036 is an old saw, and a circlip failure intimates to me that it is a saw that has been rebuilt with cheap aftermarket parts, which
I would like to know about, if I am going to step up and try to help. Also, we all need to be on the same page about topics like pressure/vac tests, or this thread is meaningless.

 

[HarleyT]

circlip damage is totally different from lean seizure damage, and pressure/vac tests are aimed at lean/seizure damage, if you
follow what I mean.......

I checked both seals for leaks, no bubbles? I'm a little concerned about dunking saw in water. hmmm?

when you do vacuum test you dont see bubles bubles only in pressure test , in vaccum you see that the needle dont stay

 

[pantelis]

I just used my compressor on the lowest possible setting, not sure of exact pressure? Couldn't find any obvious leaks.

7 psi max not over

just stay calm

Slow down here. From what I have read the op had a c-clip failure, replaced the damaged parts, reassembled and was vac testing to ensure repair. This is where the saw is now, at a point of failed vac test.

 

[lone wolf]

There we are.

 

[HarleyT]

I have only tried vacuum, so far. I will try pressure test tomorrow.

No, there we are....

Yes, we are here....Not a "pressure test"......

Sorry, I just work on this crap for a living, a decent pressure test is one thing, putting air pressure and looking for bubbles is another. Once you have a saw pass a pressure test, then you are good to perform a vac test, this guy has not done anything close.
But he has used terms that get the gang here all excited..... He has a Stihl 036 which died a wicked death, if we can believe that part.

Cant kill them they can be resurrected!

 

[HarleyT]

He next makes a vague post about the saw not holding vac..... But he has in any way actually performed a real vac/pressure test.
Here we are.....
