Ok, so that's a big-bore 460.

I'm checking another model off my list of coveted saws I need to try. I bought this saw as a box of parts last fall, and just finished putting it together today. What the previous owner thought was a broken connecting rod turned out to only be a shattered piston skirt. The worm gear for the oiler was shot and the clutch showed signs of having gotten a little warm, so my guess is that he just kept cutting after the oiler quit and the chain tightened up, and that put the extra stress on the engine that triggered the failure.

Thankfully the cylinder was still in fine shape. After removing a few chunks of piston from the crankcase I pulled the seals and rinsed about half a gallon of gas through the bearings while rotating the crank to rinse out any remaining particles of stray aluminum. Everything felt tight and smooth, so it got new seals, piston and base gasket. Passed the vac & pressure tests, so the rest of the parts followed, with a new chain catcher and spark plug boot. I was able to try it out on a blown-down cherry trunk at the end of my street, just before the rain hit.

 

It's totally stock, and the front is a bit mashed in so it could stand replacement anyhow.

 

Awesome... there's a basket-case 460 I may end up with (free). It'll need a case split and possibly a crank? I'm not sure if I'm up to it yet, but who knows. If I do it, it'll be all aftermarket parts (despite what I've been reading about AM cranks haha)

Good job on the rebuild. Nice saw!

 

Sweet !

 

The issue with messing with the muffler is it makes it LOUD!

I have a dual port in mine and you can't use it without ear pro. Not the end of the world to me, but chainsaw noise carries far.
It at idle drowns out my 660 with stock muffler at WOT to give an idea.

 

You should be using ear protection with any saw!!! My ears use to rung after running my 390 stock. Now I use muffs all the way.

My 650 with hogged out port and DP cover is loud!!! I can't hear my music in the muffs very well cause of it!!

 

I guess I didn't explain well enough.

Yes the operator should have on ear pro. But how many stock saws have you run that you NEEDED it?
NEEDED as in start it up and first thought is holy crap I'm going deaf.
I wish I had a decibel meter. I wouldn't be surprised if to follow OSHA regs it was loud enough that a person should have dual hearing pro. (Foamies and muffs).

Point I was making is that even a stock saw noise carries far. With a minimal muffler if you have any neighbors in a mile or two radius they will hear it for sure.
Picture guy down the street reving and opened header car for several hours... about the same.

Just something to consider is all.

 

Hmm , Interesting! ! ! , I have a sound level meter.
Never used it for testing chainsaw decibels.
I could test the saws I have, and ship it out and pass it around for other testing

 

50ft ?? Really?
Who runs a saw from 50 ft?
More like 2 ft
I don't run my router, table saw, planer, jointer, at 50 ft

 

OK, I get that
My objective is focused on operator , Potentially dangerous decibels.
Mostly I have used my sound level meter for audio tweaking

 

My McCulloch 10-10s is pretty loud. That thing lopes like a big block!

 

I try not to push my luck too much with the chainsaw noise, but my neighborhood is close to a major road so nobody expects to be able to hear crickets chirping anyhow. The houses are mostly brick or stone and damp sound pretty well. I wait until after 10AM on weekdays and noon on Sunday before firing up a saw, and nobody has complained yet.

Even with the stock muffler, the 460 seems considerably louder than my 361 (also stock).
