Stihl recommends never use an impact gun on flywheel nuts. Some flywheels have the key cast into the flywheel, and the impact gun can shear off the cast aluminum key. One should use a piston stop and a torque wrench. I was a Stihl dealer for 38 years and never had a flywheel come loose, and never added a lock washer when it wasn’t called for. I generally would not rev up an engine without the bar and chain mounted, you really can’t adjust the carb that way on the hi setting, and I had a Homelite XL2 with a one piece clutch break up the clutch and throw shrapnel over a considerable distance. That was a lesson learned.

A impact works fine if you can lower the power setting.

You did the right procedure. Remove the break band to get the oil pump off. That discharge line from the oil pump is almost impossible to remove or put on. I just cut it and replace it with a new hose. I did it yesterday when I put an adjustable oil pump on my ms 260, part of its upgrade to a ms 260 Pro. I have upgraded my 026 to 026 Pro, already.

Every 026 I've worked on had a nut with a flat washer back, never a lock washer. The rubber valve for the vent is really easy to change. That style cap was notorious for leaking around the seal and can even get cracks or holes from people using a saw wrench to tighten them.

sure do appreciate your videos, learn a lot. One thing I have noticed in collecting and working on saws, when I run the powerhead without a bar and chain mounted I have to be very careful with revving, the flywheel and the clutches ten to work loose, has done so several times on me, something to do with inerta and torque in the wrong way and the bar chain assembly acts as a damper on too rapid acceleration/deceleration.

Incidentally the 024 Super is a pre-026. Also on the PTO side check the bearing/case play. They're excellent saws but the air filter on the old one's left a lot to be desired.

I have done that more than once. Never blown the muffler out but have sheared more than one flywheel keys. I hit the flywheel nut twice with my impact. I don’t remember a washer on my 026P. I also put Locktite on the crank threads, blue type. The correct torque is 25 foot pounds if you want to put a torque wrench to it. My impact will usually lock it down pretty good, but I do clean the tapered surface good with break cleaner before I put the flywheel on the crank. I also clean the tapered surface in the flywheel with break cleaner. My guess is the leaking seal coated the crank and flywheel with a nice coating of oil and you didn’t remove it before you put the flywheel on the crank. Ihad the same thing happen to me on an 029 years ago.

Hey, Leon! As an European guy I have to say Stihl is good known in my country as the best of the best! But I have some doubts.. The stupid flywheels must be tighten with dynamometric wrench to certain parameters, because the lock is made from aluminium! That's why I love old Homelite saws. They are not "german engineering"! No stupid stuff there! Anyway, this video made me laugh like never before! God bless you and your family, Leon!

I'm a husky guy but I recently picked up a 660 and an 026. These are 2 of the best saws ever build according to many, and while they're both great runners, Stihl engineers are too smart for their own good. Husky seems to make it the simplest way and perfect from there, while stihl seems to say "this works, and is simple, so lets try something else." Probably just me.

Get a big 1/2” flat washer and cut a section out of it, so it will slide on the crank. Then, you can use the washer as a pry bar to help you get the seal out. Otherwise,, you can not get enough leverage on the seal to get it out. Some folks use a little 1184 on the edge of the seal to keep it from leaking if there are any scratches on the seal cup surface.

The 026 takes a big diameter .326x7 sprocket. I had a hard time finding a new sprocket for my 026. Now, I order a new rimless sprocket as a set. That way I know it will fit. I am not a Stihl Expert, but I am pretty good at fixing them. I saw a lot of things that you did that were wrong, which led to your smoking the flywheel, and caused you some grief.

If you don't get the key way lined up the flywheel will spin on the crankshaft until it comes off, usually breaking the key way. I have never seen a washer on the 026 flywheel just a nut.

@@philbrown2270 The original oil pump was a non-adjustable pump that had a crank shaft driven worm gear. Meaning it was a bushing gear that was always running. He put that back on right after he tightened the screws on the pump. You are thinking of the adjustable pro oil pump which uses a drum driven worm gear. To convert from the non-adjustable pump, you need the pump, worm gear washer, worm gear shaft bushing, worm gear, new style clutch with cover washer and new clutch drum

That was the wrong sprocket washer for a rimless sprocket. The correct one is the thicker steel sprocket washer. The thinner aluminum one is for a spur sprocket. You will probably have to tighten the clutch enough to get the EClip on the end of the crank.
