Stihl blower

[ayoungtexan]

I was using my Stihl br430 today when I was blowing leaves, when I heard a rattling sound in the engine. After a second or two, the blower seized up. I tried pulling the cord and it was seized. I tore it apart and I found a small pebble inside the engine. Any thoughts on how to repair this, should I just get a new blower?

How bad is the damage? Can you clean it up and throw a new piston in it?

Every so often you can find blowers on flea bay with some damage for relatively cheap .For example I bought a BG 85 for about 50 bucks with a damaged engine .Of which I installed another engine from a blower that lost a fight with a brush chipper .It got stepped on so to speak .

I'm curious as to how the pebble got in there.

We gonna needs sum picterz....could be a bearing....could be carbon....either way its gonna be some fun loonkinz

The br 430 blowers are known for bad crank bearings. I have replaced at least a hundred crank bearings in those, stihl claimed it was to big of tolerances in the engine pan then claimed it was the blue crank seals allowing debris to enter. Usually when it let's go like you claimed it takes out the coil, recoil, and breaks the engine pan. If it's still under warranty you will get a new blower. If your crank seals are brown it's the newer updated version.

Just seems rather odd .Something like a chainsaw it's understandable how something could get sucked into the engine .A back pack blower would be up above any ground debris unless it was ran on the ground and usually that's only to start it .I suppose some could start them while strapped on the back but I'm not one of them .BTW I have an older version of the blower in question ,BR 400

Well if,and repeat if it sucked grit into the engine that alone could knock the mains out .A ball or roller bearing doesn't take grit very well .Now I'm not a blower expert but it is a two cycle engine you know .

Take your recoil off and see if the flywheel moves any. If it does the bearings are gone.

What`s the serial number of your blower? I`ve seen it is a 2018 one, which month of 2018 (if possible), have a look on the sticker with the year of manufacture?

 

[DND 9000]

Ok, that means you have the old version (old parts). There were changes later in 2018. The engine pan is improved and there is better clamping force for the bearings on the newer ones. The cranck seals were changed in 2017, so you already have the newer ones.

They offer a short block replacement now

This thread sucks with out pictures.

?? do the br 600s have the same issue

 

[Lcfd1124]

The only two things with the 600' is, keep the valves adjusted and run a quality synthetic oil to keep carbon build up on the valves down.

 

[Al Smith]

I just took the liberty of looking up parts for this thing on flea bay .There are bunch if that's of any interest .

 

[pbillyi69]

thanks i do keep the valves adjusted and use klotz or amzoil or some other quality mix in all of my stuff
