Stihl Chain Brake Handle Re-assemble issues...

[SCoupe]

I've hit an impasse while reinstalling my brake handle on my Stihl MS250 and would appreciate any advice. The lever with the flexible links will not clear the strap when I have re-assembled it. The links hit the lever, there is insufficient clearance to allow the lever to pass under the strap. Picture(s) will hopefully show the problem.

Fish is the guy you want to talk to about this. I haven't put enough of these together to remember correctly- However, I think if you rock the brake handle forward, and move the top of the lever back as far as it will go, then the link will be down far enough that you can get the strap in place?

Have you worked that side of the brake handle as far in as it will go?

Pull the brake handle all the way back toward the handle bar. Take a small screwdriver and force the metal tang down, push down on the brake handle , done..

Here is a pic of one in it's natural habitat...

Crap. Still not getting it, how can this possibly be such a combination of finesse and force?

This picture shows metal strap (per parts diagram; tang your word?) after I've forced into place. It is arched over the links of the lever and will not move at all. The links of the lever are too high as assembled and I'm not able to work the lever with the links on it lower.

The spring tang underneath needs to be depressed while wiggling the handle back and forth, and the handle will go lower on the post.

You can start by putting that black plastic washer on the other side of the lever arm. It goes between the lever arm, and the thin flat piece of steel, not under the lever arm. That should fix the issue of it hitting.

That's why they call him the Saw Rx...

Wow, yea, I bet you're exactly right! That will certainly restore the missing clearance !

By the time I read this, it was too dark in the shed for me to attempt a re-assembly. I'll update this in the next 24 hours using the tip you provided.

Thank you for your sharp eye on the photo's!

Thank You Saw Dr. !!

Saw Dr., you're the man !

Exactly right!

Looking at the pictures I posted above it, the mistake almost leaps out at you, but I missed that important assembly sequence.

I very happy not to have to bring this in as a "basket case" to my extremely difficult to deal with Stihl shop.

Thank you and to the members who took a moment to nudge me in the right direction.

+1 for me here. The ms290 will bind the same way. THE DOCTOR IS IN THE HOUSE!
