Huskyboy meets the 572xp

[dustinwilt68]

I just personally wish all saws had 6202 and 6203 standard bearings in them and used an external seal, much like a lot of the 2 series saws. Sure makes it cheaper for repairs and easy to stock parts for.

It's mainly that reason right there why I believe the 365/371/372 is one of the best series of saws ever made. They're easy to work on, make great power for their size, use standard size bearings (and the flywheel side seal is shared with many other models), they're relatively light, and versatile. A guy I worked with in 2004 fell and bucked a 91" DBH Ponderosa Pine using a 372 running a 36" bar near Glendale, Oregon. 91" is a lot of wood to gnaw through.

No argument here JJ, to me they are still the king at that size saw. New P&C OEM for under $150.00 makes it worth while to rebuild them also.

I think the 572 has potential be a winner too - we'll see what Mason finds out here...

I’m gonna do my best to describe the power of the 572 for those who haven’t run one. It’s very comparable to a stock 7900.

Thanx, that is much clearer. So it's close to a 7900 then? Wait a minute...what's a 7900? J/k
I have only seen an old Dolmar once in 1993.

It feels like it wants a lot more bar than 20”. It did come alive when I dropped the rakers and put more hook on the stock chain. Which tells me it wants more bar or at least a 8 pin on the 20”.

I think you are saying you would like it to tip sink faster. Sure, It can glide smoothly with a faster tip cut and still knock out a Humboldt with proper felling dogs. There is definitely something left for a surprise.

It is not the amount of teeth in the cut my friend...Its the cut in the tooth.
No...It is easy to split hairs but for sure it is always about everything. 'Balance' is the best word. There is so much to consider. My job would be to get the max tip cut in the least grabbiest species that still works with the fallers dogs in an angle felling cut in the grabbiest species. It's the 9"-12" Western Hemlock that stop the saw of the dogs not the full 36" bar length in Hemlock. Think about why that is for a while?
Bar length follows suite.
The smaller the saw and 'with the bigger the dogs' the greater the challenge.
(Deeper the dogs^^)

The 572 is much more powerhead biased balance with a 20” bar. Needs at least a 24 and probably perfect with a 28”. More of a long bar torque saw, and the chassis/ bottom end appears to be built strong to handle that.

Just say it Mason. "Bitçh you got a fat àSS". Yes for sure it will balance with a 24" heavy or a 36" Stihl lite as does a 372. They actually moved the handle bars back 1cm (10mm) to
. . .

I know here in RI, I do not know one Gov't employee who would check guys with chainsaws for screens or saw mods. Just no manpower for that.

I believe he must be talkin about G&O (gas & oil industry) 12 yrs ago I have had friends that were/are getting $1,200 a day to do it to. Equipment and PPE audit's. Competency testing to fall and buck on programs and going on Seismic lines and doing reports on our work. Stump quality and how you go about it and repeat equipment and PPE audits.

 

[RI Chevy]

I was referring to enforcement of screens on chainsaw mufflers and to check on engine work.

Not just oil and gas anymore, we get checked quite often logging now both on the coast and the interior. Worksafe BC have really cracked down on things in the last. Usually once a month or so someone will come by to check things out.

I do a fair amount of quality checks on guys as well as I’m also a QST.

Oh I know all about it. We have been shut down for Mod mufflers by gov fire oficials too. Seen Work safe BC three times In one shift. All falling accidents.
One of them was a fatality. One of the others that got hurt..ended up getting killed 7 months later in feb 2017.
I thought you just worked in AB?
So you fall on the West Coast?
You QST under Inform then?

that is what I was talking about
Modified saws.

I guess you were in the American conversation and I was reading the Canadian conversation. Silly us.
Pulling them apart? What is the point of that anyway? If they recognise it to have a mod muffler. Sounds fishy???

I work all over the place depending on the time of year. I spend most of my spring and summer falling in BC and the fall and winter in Alberta. Of course that just depends on where the jobs are but yes I do some coastal falling as well.

Yes I’m a QST through ENFORM (now called Energy Safety Canada since they combined with OSSA in the oil sands) since 2006. It’s kind of funny how everything changes with our standards. First ENFORM adopt the BC Faller Training standard and now BC are changing their falling courses to mimic the ENFORM program. It’s mainly because not many people want to spend $40 grand on a 30 day falling course anymore, they’re going towards more on the job training under supervision after taking a shorter more cost efficient course. Their program hopefully will be approved this year as they have already ran a couple of pilot courses.

Any saw is going to waste the clutch side bearing at some point with full-time professional use. I cut full-time for several years for three large logging companies here and my modded saws lasted just as long as my stock saws, or my co-worker's stock and modded saws. The maintenance the machines get pays a much larger role in how long the machines last. What's more likely in a professional setting here are the clutches and mufflers blowing out, ignitions failing, and big end rod bearings failing due to debris ingestion. What gets the landing saws the most are the PTO side bearings failing or the bearing pocket wallowing out due to the saw being forced to run with a dull chain day in and day out. There are a lot of ham-handed operators on landings here and the maintenance those machines get is minimal.

It's the right move for Husqvarna to put beefier bearings and cranks in the 572 - Solo did it years ago in the 670/680/690/603 series and those saws lasted a long time in the woods.





It's a regional thing - Oregon Department of Forestry and Washington Department of Natural Resources are pretty gung-ho about modified equipment of any kind on their lands (saws, yarders, loaders, feller-bunchers, etc). A few years ago, Agee logging started a fire near Elkton, Oregon due to a log loader that had no muffler and an exhaust that dumped out straight to the ground and they got a big fine.

There's not much cutting on Federal lands here anymore but back in the day, the Forest Service and Bureau of Land Management were also very gung-ho about chopped up mufflers. The difference on the east coast mainly has to due to with the different conditions guys run in there and the logging operations tend to be a lot smaller, in addition to the fact that there's many more road systems there.

Also most company ground it’s the same as government ground, when was the last time you saw level 4? Since I’ve been out in the woods I never have seen one in the upper districts, I remember being told of month long shut downs in the summer.

Here in the East we have mostly hardwoods, and it is very unlikely that an unscreened saw is going to start a fire … unless you opened it up in the front!

Likely, they monitor these things where they need to and don't monitor them where there is no need.

 

[huskyboy]

I think we should let sleeping dogs lie as treemonkey wisely said.

 

[MustangMike]

Yep, and I've been porting Asian saws, so I can't get fined for modifying an EPA certified engine!!! They don't have a S/N or an EPA sticker!

I've only seen IFPL 4 three or four times in my day - they did go to an IFPL 3 here on the coast in 2017 which is extreme for the coast. We went to an IFPL 4 in the South Central Oregon fire management partnership in 2011 and
2013 - both of those seasons the Fremont-Winema, Umpqua, and Rogue-Siskiyou had very large project fires.

District NW 2/3 we’ll see a level 3 about once a year not exactly the most fun to see on the hottest days of the year.

Well, let me add "A lot sooner" to my prediction on the clutch side bearing. Given enough run time, not to mention dull or overly aggressive chains, the clutch side bearing will give it up. But a 30%-40% increase in compression on a modified saw will get you there sooner in most cases.

 

[MustangMike]

It would be interesting to conduct a test (but not sure how) regarding if a modified saws cuts less wood before it fails (as opposed to just a time line).

I believe that muff mods and removing the limiters generally result in a cooler running saw, and that the top ends generally last longer, not shorter.

I guess it may depend on what fail point you focus on. Personally, I run Amsoil Saber at 40:1 and I have to say my saws all seem to be real well lubricated when I take them down. I also believe cheap Chinese bearings that are well lubricated will last longer than great OEM bearings that are not well lubricated.

I believe the oil used, and mix ratio, would make a dramatic difference in the results.

 

[RI Chevy]

I think there would be a lot more variables than just oil Mike. Many many more.
