Impact wrenchs are no no for chainsaws

I worked in various bicycle shops for 6+ years. When we would get a new guy in I would be ready to plug my ears when he would go for the air hose to inflate tires. If you don't understand that there is 100+ psi in that hose you'll blow the tire off of the rim. The experienced guys will give it short bursts to control the inflation.

Experience is one of the best teachers.

If you grab an impact wrench not thinking about the psi the compressor is putting out, not checking the power setting on the wrench, and not knowing the direction the nut turns, you are going to destroy something.

I can see how a piston stop could punch a hole through a piston or put enough force to bend a rod. I also can see how a flywheel key can be sheered by the inertia of a HOT impact.

An excavator in the wrong hands will easily punch a hole through a wall when used by an inexperienced user. Does this mean that excavators shouldn't be used to dig by a house because the guy down the block didn't know what he was doing and put an extra door in his bathroom? (that would wake up someone reading on the white throne!):biggrinbounce2::hmm3grin2orange:

Tools in the wrong hands will do wrong work. With a large enough impact, one can strip out lug nuts on cars. Think you know which way the nuts turn? Take my 58 Plymouth. It doesn't have lug nuts. It has lug bolts. AND, the ones on the left side ARE left handed. If you didn't know that, you would keep turning up the psi on the wrench until something gave. I bet if I took my 58 into a tire shop, the guys in there have never see left handed lug bolts, and have troubles with them.

With an impact, start with a low setting, know the direction of the thread (there's usually a bit of thread sticking up that one can use to determine the direction), and if it's not coming off, stop, think.......ask questions.

I have to chuckle at this thread.

It's starting to sound like one of those...


I've been doing this since I was knee high to a grasshopper...

My dad's dad did it, my dad did it, I'm going to do it...

Welp, it was good enough 20 years ago it should be good enough for today...

I ain't never had a problem doing it this way, so I don't expect to ever have a problem...

Etc...



Am I the exact same way about some stuff? YEP!!!:biggrinbounce2:
 
i have to say i dont like the idea of the piton stop at all wether with rop or metal or my finger.

when if i ever pull a clutch ill use my 18v dewalt 1/2" impact and make dang sure im going the right way before i hit trigger.

but if i had to use a piston stop it would definalty be rope, cause it gives and spreads the force out some
 
Sounds like your full of yourself today Gregg. Why wouldn't he have that OEM clutch on that saw, don't new saws come with OEM cluthes on them?? And no he wasn't holding the flywheel, why would he have to, he used a impact wrench. I think he went the wrong way trying to take it off and that hammering from the impact wrench tighenting instead of loosening did the number, pretty obvious since nothing was broke untill that impact wrench got ahold of it. Good reason not to use one don'tcha think,:hmm3grin2orange::hmm3grin2orange::hmm3grin2orange:

He didn't have any idea what a piston stop was, so of course he held the flywheel. Probably had a screwdriver wedged between it and the coil, while he was impacting it the wrong way. :laugh:


Myself, I'll keep useing the impact when I deem it appropriate, and that's alot of the times.
 
Howdy,
I'm always full of myself. If you didn't wipe your nose after you shake my hand, you might not even know. I threw this in "And now back to your regular programing." hoping folks would know I was kidding. We pretty much dealt with Husqvarna as far as sales go. Until the recent past they all had outboard clutches. 8 tooth rims were pretty popular in these parts. We would have customers show up and buy 20 or more saws at a time and want the rims changed. By the time we changed the rims, fueled, oiled, and adjusted them, we were into it a couple hours. You add R&R top covers, R&R spark plugs, R&R piston stops, and it could double the time. Our way the customers could go have a meal, and a couple beers, and be on their way. This was important because we're in the middle of nowhere. We would have people drive a few hours to get here without a heads up, and expect to leave with everything they needed. If it was late in the day, the old man would have to pay overtime, and buy the beer. This was frowned upon.
I"ll have to agree with you that the impact wrench might not be the best suggestion for the end user.
P.S. This might turn some peoples hair gray but, we torqued them with the chainbrakes.
Regards
Gregg

LOL, dayumm if you aren't full of yourself today but in a good way, cool beans.

That flywheel I showed is the third one I've seen in the past few years that was sheered by use of a impact wrench on a clutch. Does show most survive but a few don't. This time the the clutch carrier broke too and the customer admitted how he did it. I though it was just good info to pass along. As you can see many are still intent to use the impact wrench regardless and thats cool.

While I gotcha here you guys miss Husqvarna? I know yaw rolled out a bunch of them.

If a piston stop is leary to ya try taking the fanwheel off a BR550/600 blower.
That fan wheel is so tight you would swear the piston is going to bust any second. It amazes me how strong that piston is. Have yet to bust one though, knock on wood....
 
Damn molded flywheel. Instead of new key, which are either free or dirt cheap, the guy has to go with a new flywheel at the tune of 90 bucks.:bang: Being cheap helps Stihl in production costs and parts sales.:chainsawguy: I do understand that technically, there is no reason for the key to shear, but #### happens and the wallet is really hurting.

I just put together a 361 like this. Key was sheared, so I just lined it and cranked it down. Hopefully it stays put, but it would have been really easy to just get a new key. It is a professional saw for a reason. Don't neg rep to bad 361 gods:bowdown::hmm3grin2orange::hmm3grin2orange:

It will stay put, the key only lines it up, the taper keeps it tight and in place providing you don't go hammering on the clutch with a impact wrench,LOL

Whats wrong with 90.00 for a flywheel, we poor folk gotta eat too,:hmm3grin2orange::hmm3grin2orange::hmm3grin2orange:
 
Howdy,
Without Husqvarna, it really cut into our gross sales figures in a big way. They were more of a loss leader in that our margins were often 10 points or under on powerheads. We didn't have to buy bars and chains with the powerheads. If we sold a bar and chain with the powerhead we could decent margins on the bar and chain. If we sold just the powerhead there wasn't much there for us. The good news is that our margins have been growing ever since. It did force us to diversify more than we had in the past. People that have been with us awhile can notice that we've brought on many more lines. We're making great strides in the Lawn & Garden / Landscaping markets. I have to do a quarterly sales variance report, the Husqvarna red ink is getting much smaller every time.

Well I know who is buying the folgers and beer when I come down some time. My brother lives in DC. Gonna have to cross the Potomac next time I am down:D:D:D

I think someone did take an impact to this saw, as the clutch spider broke all three prongs and the flywheel key was sheared. I got it running good last friday. I believe the saw was running bad and someone thought it had an air leak, which lead to them tearing the saw down to look at the seals. What I think was the real problem was the tank vent was clogged. The cover was missing and when I removed the air filter and gave it a blow (the gas tasted great:dizzy:), it had little to no movement. A pressure and vac test showed it was good. A new vent and a new clutch (which I randomly found in a drawl) and that thing was running good. Still now 262xp or 036, but still very nice.

Margins is what its all about. Sounds like you lost some volumn but are making it up in other areas with better margins, good job.

The place I work at it seems everyone is calling wanting to know when you putting Stihl on sale or they are at the rack seeking big discounts. Not just a customer here and there but more like 8 out of 10. We know they are using the recession to justify they're way of thinking. As of Friday morning I went to the boss asking to put our foot down. He agreed 100%. The answer has gone from explaining we can't discount 25% on a saw marked up 20% to a simple NO. Our volumn may suffer a tad this year but the margins will be there to make it up. I kinda like saying No, I'm getting used to it real fast and no one has walk out yet, they buy anyway and go on about their day.

Lawn and garden is a good margin market. Guy at the local garden center told me every f-ing plant I sell is marked up triple to make up for any that die,LOLOL

I got yaws catalog here and I've been browsing through it looking for a pencil grinder and bits so I can chop of some cylinder ports, don't see any in your catalog, do you guys carry those???

Well we pay 89.99 for that flywheel, not much coffee or beer money. Hmmm lightening just struck the house,LOLOLOL

Stop on by when you go see ya brother. Tant got no beer or Folgers at the store but I'll buy ya a cold Pepsi,:cheers::cheers:

Have your local Snap On guy swing by and show you their Blue Point Pencil Grinder, I like it.

I don't quit get your logic in that making a mistake in the use of a tool means you shouldn't use the tool correctly either.

If someone happened to do some damage to their saw using a rope in the cylinder incorrectly, you would no longer recommend using the rope either?

You gave the guy a piston stop and people have put holes in the top of pistons with them before.

Seems like you have the logic of a liberal:laugh:

Logic is simple, the results of the impact wrench are in the pic. Stihl makes it clear do not use a impact wrench on chainsaws, the pic proves why. They recomend a piston stop, I'm just going by the book. Never damaged any saw myself using a piston stop. I don't recomend rope, piston stop works fine,LOL

You have the logic of a conservative, all what if's. What if he hadn't used that impact wrench, this thread wouldn't be here would it,haha

Tom, what do you make of Brad bending a crankshaft with a piston stop? Poor technique, uneven application with breaker bar, or?
