husqavarna 77cc .404
« on: December 27, 2016, 03:52:04 AM »

Ok I sharpen my own chains and i was thinking on going to .404 so sharpening would be less .
anyone have any input on using .404 chain saw chain . Im thinking on 16 inch bar or 20 inch for bigger logs .
I do know with my sharpening 77 cc will be more then enough power . if its a issue on 20 inch bar I will just set
rakers at .020 .. any input be great . I have pretty healthy husky 77cc . but next saw might be a dolmar 78cc
they look identical to my old 1981 husqavarna 77 . ya look at price of 576xp husqavarna ya wow ..

You won't have a problem with a 77cc engine, if I'm not mistaken husky claims 4.9hp on that saw? a 20" chain won't be a problem because that saw can turn 28" with a 3/8" . My pops runs his saw with a .404 sprocket/chain and swears by it.  He says it takes a lot more saw to pull it but still runs 404 on everything. It holds an edge much longer and it is way more chain for an extra few dollars. Hit a rock with a 3/8 hard enough, and it is junk.  He sharpens my chains as well and tells me I should go this route but I'm more of a "this is what it came with" kinda guy.  Plus for the 100+ it would cost me to swap it out my saw cuts good :) and my chains are always sharp ;)

Meh, 404 just cuts a wider kerf so more to cut and drag out of the kerf.

I run semi chisel .404 63 gauge on my fire wood processor because I got tired of snapping lighter chain.

I got 20 inch bar and full comp chain .404 on order. Im also going try a full skip .404 cant find a semi skip. On a 7 tooth rim .  thanks for the input . I read some old foresty literature and this guy was talking about his 1981 77 and with .404 chain and he said at the time was best all around big timber cutting saw. And .404 chain was a perfect match for this saw . because 3/8 chain always loaded the bars with chips under chain . well I will find out if its true. Because I do know full comp chains are prone to doing that mine did it thats why I was trying out the full skip . but I think the other thing looked over was wider kerf saw would pinch less. I could be wrong but Im going to find out. Main reason I like .404 edge holds up better thats a big plus.. Thanks for the info..

Just so you know your dad's right. It works way better chips everywhere. Also you can push on it and chips don't go under chain like 3/8 chain . Chain cleans chips way better. And I noticed also I need to use a 8 tooth because rpm wise I'm still low with the 7 tooth
8 tooth is on order. I have no idea why people dont use .404 more
It's way better then 3/8 chain .  It cut just as fast as 8 tooth 3/8 chain . And I had .404 7 tooth so 8 tooth  on .404 will be perfect . I also got a .404 .063 20 inch full skip chain to try yet . I'm totally happy with .404  it will be on the saw from now on . Mandatory.
It's well worth extra cash. If you shop online it's almost same as 3/8.
I cut mostly oak.. saw bit over 5.7 HP but I don't know if it 6 HP..
If you get the chain running inside power band window it's unstoppable. I'm going to be mad the day 77 wears out it will get a glass box in the shop. Best saw I ever owned. 👍

 When I get the 8 tooth sprocket on I will make video and post it . Because on other wood forums they really don't know what there talking about . Most guys think 3/8 cuts better then .404 and .404 was only for the old saws .  Thats all because they never used .404  and they just don't know .  Blocking oak its the power house .. If you cant pull .404 use 3/8 but anything over 70 cc should be able to pull a 20 inch  you can always raise raker to .025 instead of the .030 . But remember I have older sweden saw
there might be differences in newer plastic saws That I don't know about  . :thumbup:

Then newer plastic saws are the cheap ones.  All my saws are metal "pro saws"! I couldn't justify buying a plastic saw, even my Remington is a "pro" with metal casing lol

One thing you mentioned is that you were wondering why everyone doesn't use a .404 set up.  Well that is because they are harder on the crank bearings of a saw's engine.  It has been said The engine "can" wear out faster and I think that is why many manufacturers choose to use a chain that is going to make the saw last through the warranty period.   To me I think that is horse manure and it all comes down to care and maintenance but to each his own.

Yes I think it goes deeper . because you take sharp .404 always sharpen on bench style grinder . It cuts just as smooth as 3/8
this is what I'm finding out ..  So If you sharpen with a file and or ruff sharpening yes its harder on saw . So it comes down to Like you say maintenance and care of chains and saw ..  sharp chains and maintained saw cutting wood is almost 70% easier on operator and  more wood is getting cut also .. .404 .063 full skip on 7 tooth 20 inch 77cc Is like a serious chip explosion at the wood pile . bigger logs .

It's funny you say that.  I was outncutting last weekend with dad when it was 70 degrees out and his saw actually plugged the underside because he was cutting so fast with an extremely sharp chain.  Not a big deal at all but I was impressed at that. His 461 with a 25 inch bar will cut faster than my 661 with the factory 25 inch bar.
