Husqvarna 2100 refresh

[Whitty21]

Well after the drama of the wrong saw being sent and then the correct one being trapped in an evacuated town because of a forest fire.

Here it is

 

[Whitty21]

It blows 155psi cold on my cheapo tester.

Looks like I may pull the top end and throw some rings on it.

 

[Frank bierce]

Awesome!! Glad to see it finally got worked out!!

 

[Redfin]

Is it a runner?

 

[Whitty21]

No air filter on it but I got it going and it runs well and oils

 

[Whitty21]

Anyone able to confirm that this is a thick ring piston by looking at it? I will have to tear it down, but it would be nice to order the rings first.

Also, is there generally enough room to run these without base gaskets?

For what it's worth, I removed the base gasket on my 285cd and the squish was perfect, about 0.025" IIRC.

Those appear to be thick rings. If the saw is running well why do you want to tear it down?

I would feel slightly more at ease with the transfer from the slight rubbing on the exhaust side cleaned up and some new rings

Glad u got it! I'm with redfin on maybe keeping it together. Looks more like scuffing from carbon from conventional pile. I think maybe the good fuel and full synthetic, and it would cure that. I could be wrong, but run into the same problem.

Any updates?

 

[Whitty21]

The rings just came in the mail. All the other parts are on the way. Then I just have to find time to do the work

 

[Frank bierce]

Nice!! Will be a good freshen up!

 

[Chainsaw Jim]

That's a good choice on the re-ring job. That saying: "if it ain't broke don't fix it" always applies, but I strongly believe in a full dismantle for internal cleaning/inspection when buying an old well used saw like that.

Much better to check it out...replace rubber goodies, clean and once over..before it gets burnt up!!

 

[Whitty21]

I think it is also leaking gas into the oil tank. From some reading I think this is happening at the manual oiler. Anyone have a source for replacements or a size I can look for at a hydraulic shop?

 

[Whitty21]

Just answered my own question. Looks like the 3120 uses the same o-ring. The updated part number is 740422200 for anyone's future reference

Edit:

NVM, that is the updated part number for the oil pump o-ring, not the manual oiler, back to the drawing board

 

[Normzilla]

I agree

 

[Whitty21]

Remembered to take a starting pic this time.



Just got an v-stack from Shaun in the mail and figured I would mock it up before I tear everything down. Ended up having to file around the bolt hole of the support bracket to fit the 288 intake I got for it.


Tore the cylinder off. Piston is useable. No high spots

 

[Whitty21]

Lighting in the garage wouldn't allow for much of a photo of the cylinder. Bottom is a bit speckly. No real transfer on the cylinder. Just a light sanding required. Under the exhaust port there seems to be a lip of carbon build up which I have never seen before. Calling it a night at this point
