Huskyboy meets the 572xp

[huskihl]

I'm curious on how tight is to tight on chain tension. I have a new 572, so far I'm loving it. I put enough tension on my chains that I can pull them down, but the drive links can't come out of the bar fully, maybe 1/2 way... To much, not enough?

Hi Joe. Good to see you over here

I was taught that when chain is properly tensioned, you pull down on chain and only 1/4 of the drive link should be in bar groove. Chain should snap back up.
With that said, I prefer a slightly looser chain.

 

[Joe P]

Sounds like I'm in the ballpark then.

Huskihl - your saw is a beast. I can't wait 'till I get into some bigger wood with it.

This technique doesn't really compensate for varying bar lengths. That tension might be fine for a 20" bar, but I'm guessing if you put a 36"+ bar on a saw and tightened the chain so you could only pull out 1/4 of a drive link, it'd be awfully tight.

Exactly! you can easily over tighten chains on long bars, enough to pull the chain against the bar and a hair more, that's it. When cutting the smalls with a shout bar, yeah I tighten them down a bit more.

It was a general description guys. But thank you for the corrections and help...

 

[huskyboy]

I can definitely see how too tight a chain can beat on the pto bearing. Makes sense. I just turn in that little screw on the side cover until the chain isn’t sagging off the bottom of the bar. Works for me. I guess I could try some different techniques this coming week and see if it makes a difference. Ttyl guys I have to get back to work. Lol

 

[davidwyby]

I’m picky about chain tension. I tighten until just a little resistance in the tensioner and while running the chain around by hand...but then they invariably get a little loose when run hard, so I carry a scrench. Or in the case of my silly full wraps, a wrench and screwdriver.

Nice Mason. That 572 is working really well. [emoji106]

I filled up my 572xp with gas/oil and fitted it with a 24” tsumura husky mount bar/chain ready to cut. Then put it on a scale to see what it’s ready to cut weight was... I then setup a ms462 with a identical 24” tsumura bar/chain except in stihl mount. Filled with gas/oil. Then weighed it. I got.... There are some dreaded variables in this . The 462 has a larger spike and roller catcher fitted to it. The 572 has a muffler mod and a little cylinder port work. The bars being different mounts (same bar though). The 572 has a outer dog and the 462 does not. The 572 was filthy/used and the 462 was new and cleaned. The scale does not show the mere ounces that we all argue about . Take it for what it’s worth. I did this out of curiosity, I was more interested in what kind of weight I was carrying around for 6 hours than a brand comparison. Any generic 70cc saw with a 24” bar is going to be around 20 pounds give or take a half pound setup to do what I do. They both will tire me out by the end of the day. I think that using a lightweight bar instead of a normal weight bar... would be more noticeable to me than the difference in weight between different brand 70cc saws.

Yes. Quicker handling, too, as the reduced bar weight equals less rotational inertia while maintaining the durability of the power head.

Nice comparison, would be nice to see the new husky lightweight bars about to hit the market that have the tsumura design now that the two companies struck a partnership. Maybe @Spike60 could give us some early specs and observations, these should now be easier for the masses. I plan getting one once they show up at my local dealer.

 

[Spike60]

Ummmm, I guess the cat is out of the bag, or will be soon. The plan is to source bars from Sugi-Hara. No idea on prices yet. Don't know if they are just buying bars, or buying the whole deal. Have a couple of 24's. Same as always , just with Husqvarna written on them,. I'm hoping for more variety if this goes through. Like a 36" bar that comes in something other than .063 for one. And some small mount bars in .058 would be nice as well.

 

[MustangMike]

The irony ... I could not get Stihl 36" bars in .063 on the East Coast! (My 24" and 28" bars are all .063)!

I figured the wider groove would carry more oil for milling, but the .050 seems to do OK.

Are husqvarna x-force bars staying in production ?

I would expect so. They are just the less expensive laminated bars or the 400 series saws.

 

[MG2186]

Bob do you know if they’re going to be just a relabeled Sugi bar or are they going to have them build them with different specs? Sugi’s are great bars but could stand to be a little more “reduced” weight than they are

 

[ZERO]

@Spike60 Bob, not stepping on anyone's toes, some dealers have videos on the net not mentioning anything about them, but you can clearly see them in testing or early production. It can be easily missed unless one knows what to look for. Just not sure if it is at the stage where specs can be discussed. Just like with the upcomming unknown saw about to launch.

 

[Spike60]

Don't know of any specs; just a sugi bar with husky graphics.
