064 cylinder comparison

[Chainsaw Jim]

I don't have any kind of scale to weigh an 046 poly flywheel with. I'm curious how much lighter it is than the 064 flywheel.

Right, who weighs stuff everyday? Most of us just cut wood. Then we discover the internet.....and saw forums.

My 064 is a wrap with a west coast clutch cover. Be interesting to see.

I can weigh a wrap west coast cover 064 right now

I don't have a 460 flywheel but a 660 poly flywheel is 1oz lighter than a 064 flywheel.

poly MS460 flywheel is 12.4 oz
064 limited flywheel is 1 pound 1.6 oz on my scale

5.2 oz's is a lot of weight if it's in a hippies backpack, but not for a saw. I thought it felt like more of a difference than that in my hands. The bigger difference between those two are the g-forces in resistance generated at throttle up.

It is all rotational weight (as opposed to the case, etc). The lighter weight may aid in responsiveness but the additional momentum of the heavier flywheel may help it to maintain RPMs in the cut. Maintaining speed is easier than accelerating, so if you don't loose RPMs when you hit a small knot (etc) than can provide more consistent performance for a working saw.

Jason, I know the 064s were lighter than the 660s, but did not realize they were that light! W/O the wrap handle, that may be the same as a 460!

The 044/440 is a lot lighter (14 lbs +/-), but the hybrids generally don't have the torque of a well ported 460 or 461.

Now, if you take a big bore 460 P&C (54mm) and put it on a 044/440 frame, you will have a saw in the mid 80s (cc) that only weights about 14 lbs, but, could you make it run!

My 064r is a couple ounces more than my non wrap 460 and will destroy the 460 with any length bar. That's why my 460 and 046 never get ran.

I've never liked how a 44/46 ran,to peaky

You have me curious. I'll find a accurate scale tomorrow and measure my non HD 064 against my 460.

Mine were both dry and clean. The 1122 saws hold more oil and fuel so both wet will be a bigger difference. Curious to see what your results are.
