I just ruined a cylinder with a piston stop tool

[Sam R]

You mean it doesn't magically repair threads? I'm just an adherent to the Stihl training, which says to never use impact or power tools when working on O P E. Then again they also optimistically tell you to gently work the case apart for split crank designs as if it's possible to just separate them with your bare hands. Still, might try your method one of these days.

I once had an 041 with, among other problems, stripped threads on the flywheel side & it was just completely missing the nut. Guy who sold it to me said all it needed was a carb kit.... I've learned so much since then.

Ruh - Roh !

In that same lot there was an 025 with nothing more than a flywheel left on it. Case intact, handles, trigger... No muffler, plug, top or either side cover. No coil, no carb, filter, no clutch. Might have even been missing the tank caps.

Yes, I remember the Stihl training videos, the guy in the video was trying to rebuild a carb wearing thick leather gloves. They said I could go back to work, instead of watching/laughing at the videos.

Stihl just wants you to be challenged at work.

Working on some of their saws IS a challenge.

For instance having to remove the gas/oil cap from the 170/180 in order to take the rewind starter off? That's some Poulan Pro stuff there.

Wow!!!
That is a challenge?????

 

[Sam R]

Hey don't make fun of the guy who rebuilds carburetors in falconer gloves. He's still learning.

Installing the carb boots on the 170/180 isn't fun either.

Thats the older mag case saws, 3400-4000. Ain't hard to pull the gas cap.

Yes, they have tiny feet!!

 

[Sam R]

You're right, not hard to take the caps off - just weird that Stihl designed it so you have to take them completely off to take off the rewind cover.
I don't know if I've ever encountered a Stihl that was really difficult to work on. The throttle linkage on the 024 is pretty frustrating. In all they're pretty simple, though. Actually now that I've done it awhile none of any of the common makes are all that hard to deal with.

When using any kind of "stop", the piston is up against something hard. And any whacking is risky.
When using something with impact action, nothing is hitting anything, excecpt the impact on the fastener, and that is what breaks things loose and zips it right off.
No holes in pistons, no bending rods, no damage..

I agree with you, but my concern is the potential damage to the rod bearings. I use an impact on the removal and instillation of a nut if it is my saw, but do not use on the instillation on a customers saw. Tom

Explain how it could possibly hurt the bearings?

I do just the opposite. On Bro in Laws saws I use a big hammer and a chisel and use care and thought when repairing my own stuff. I like to use BIL's eq for practice experience. I don't charge him anything when I work on his eq, but I do not let him watch.

If a rod bearing fails due to the use of a impact wrench the bearing and equipment is not intended to be repaired, it's to wimpy in the first place.

I have a pushmower on the stove!!!

Think it's time to talk about your addiction.

That's why you boys keep bending your throttle rods! Didn't your mama warn you?
