I was wondering if you were going to use the "rope down the plug-hole" trick. I try to look at the last thread coming out of the shaft to see if I can determine thread direction. It looked to me while you were showing the close-up of the crack that it was reverse threaded. But looking at the back side of the nut, it looked standard threaded.
Yep, I have used the old rope in the plug hole trick many times. And ya I was looking at the thread direction during the closeup too, and I agree with ya I think it is reverse thread.
you can but you need to make sure both valves are closed on the compression stroke, not a flathead like a B&S 😀. i took a bolt same size and thread as the spark plug i think 12mmx1.25 and made a piston stop
*Man, I thought my br550 repair was going bad. You snapped the crankshaft bolt off, no coming back from that except replacing the crankshaft so luckily you were able to find the cheap one online because that crankshaft is so expensive from the dealer that it's not worth repairing. Also, to keep the engine from turning just remove the spark plug and shove in some old starter rope to bind the piston, problem solved.*
Yup, i have used the old rope trick a few times. One time i had the rope end get cut off by the piston because it was sticking in to a port. This is only a hazard on a 2 stroke lol!. Ill be posting the rest of this br600 story real soon. Check out my ms290 sob story too.
I had an issue..bo spark on a br 600....new coil...switch was working and no grounds...come to find out magnets on flywheel went bad ...put a new one on and fired right up....really had my head scratched ...i thought i had a sheared pin as well on the flywheel....
Thankyou for the time and trouble you went to, to educate your fellow man. I too have the Stihl BR600 which I bought brand new. After about 100 hours which is basically nothing the blower also has failed crankshaft bearings. People should be aware that this blower has a host of design problems and I would categorize it as absolute junk. Do not buy one of these !
It's been a minute since last we visited the BR600. I haven't finished the video yet, but wondering if someone put some gunk in it to increase compression or reduce rod noise for shady resell purposes? Perhaps less of sugar in the tank and more of sawdust in the trans? Maybe some gunk was added as a means to gain compression to get it started?? idk
That goop looks like a combination of dirko(red sealant) and oil. Whoever owned this blower before you either allowed the factory sealant to fall into the crankcase when they removed the old stuff, or they put way too much sealant on when they closed it back up. That stuff mixing around in the crankcase is no bueno.
Yes, more importantly it'll mess with fuel delivery since the oil fuel mix has to pass through the crankcase to lube the bearings on it's way to the combustion chamber, leaking seals will definitely wreak havoc.
Common problems with BR500 to 600 series on this machines that engine pan start to leak from sealing ! That's why your engine has much of dirt from 2 cycle oil ! There is alot of information about issues to look in the technical / service manual on these machines if you look it up ! Stihl recommend that you use their tools to disassemble it / aassemble it !
I was under the impression that using an impact on the flywheel nut is also good practice. Couple bumps forward and a couple bumps reverse if no action. I learned that from watching mustie1. Also, as @cheeto4493 suggested - rope in the plug hole.
Yeah, I'll still use that method on larger motors. I think the trimmers blowers and chain saws are just too small to take the abuse......live and learn.
Dude I hate to tell you this but, it lack of correct mix or use of outboard motor oil and zero maintenance. The best way to fix this is short block. No used stuff because it's jus a bandaid fix.
I just bought a br600 used and I’m learning so much about the design. I’ll be interested in watching part 4. You definitely have more patience than I. Thanks for sticking with it. 👌
Someone has had that engine apart before. Whoever did it used way too much Dirko. You will always have at least some oil that has fallen out of suspension from the fuel mix at the bottom of the engine. It looks like someone was using regular motor oil instead of 2 stroke oil.
@@stevewatr it's very unfortunate because it happened when I lent it to someone else and they said they never refueled it or noticed any problem so I just don't know the whole story 😥
@@stevewatr I rebuilt a br600 and the exhaust port was blocked. But further lookings into that video I think u need a new engine block because of the rust.

The stuff in the bottom is grease that was around the shaft since it doesn’t have oil

Does this 4 smoke have the same failure that when the crank case seal is leaking, it throws off the mix? Asking for a friend.

"...just asking for something bad to happen. Let me put this between my legs." The most unfortunate mashups ofthoughts and sentences. LOL!
It is possible to drill and tap the end of the crankshaft and screw in a bolt or a stud medicted with never gonna remove it Loctite or some such.

That is a brons bushing instead of a roller bearing. That goes bad from using wrong oil mix.

Stihl makes a piston stop for these, part number 4282/00. Makes all your crank holding issues go away
Have you tried cleaning the screen resonator thing on the muffler. I once had a craftsman hand-held blower that wouldn't run/start until I cleaned it.
Thanks. But this thing had bigger issues lol. Im back to working on it so new episode coming.
Hola como tiene q ir montaba la leva en q posición tiene que estar la leva estando el piston en P. M. S
What way did the fan blade come off rotation
I do not remember. Sorry

Muffler bolts usually come out pretty easy
I was too chicken to try. I did get a used crank and piston so ill see what happens
My BR600 flywheel nut comes off counter clockwise
Yup, realized that the second I snapped off the end.
Of course I comment before watching. It's my thing.
you supos to turn that the down word position,that why it broke.
If interested I have a friend that has an abundance of stihl parts, his name is Jim, he is in ct. he deals with exclusively 4 Mix stihl blowers
Hey Matt. Thanks for the offer but I already got a used crank with piston off ebay. Just have to find time to put it together and see if it works
I just bought a br600 used and I’m learning so much about the design. I’ll be interested in watching part 4. You definitely have more patience than I. Thanks for sticking with it. 👌
It is firing at the wrong time ,it sheered the fly wheel key
Someone has had that engine apart before. Whoever did it used way too much Dirko. You will always have at least some oil that has fallen out of suspension from the fuel mix at the bottom of the engine. It looks like someone was using regular motor oil instead of 2 stroke oil.
I blunt forced one and snapped the head clean off the block 🤦🏼♂️
Would also say sludge was poor quality oil with mix set too rich
Yep.. I tried to take the impeller off the crankshaft and sheared the flywheel key.
at least you didn't snap the crank like I did.
@@stevewatr it's very unfortunate because it happened when I lent it to someone else and they said they never refueled it or noticed any problem so I just don't know the whole story 😥
Your exhaust valve is blocked. That's why their is so much rubbish in their.
Valve looked like it was seating okay. Do you mean the exhaust port ?

Someone got lucky its not working here
You talk too much.
