Husky 257 chain catcher screw

[lambs]

Working on the saw for a friend and realized the screw holding the chain catcher won't tighten up. I'm reluctant to use a bigger or longer screw because of the risk of damaging the crankcase. What's the best fix for this?

Thanks.

Sounds like the hole is stripped out. You could try to chase the threads, but it sounds like you need to re tap to larger fine thread screw. Gotta have a working chain catch!

Replace the AV mount.
The screw goes into the threaded end of the right-front AV mount, not the crankcase.

Nope. Chain catch is threaded into the chassis.

Well, I've learned something but sorry I haven't helped you.
Looks like there are 2 types. This is the one I've seen, same as 254.


Is this what you have?

 

[Stateline Sawer]

Yep, that's the only style I've seen around here.

Makes sense. The only 257s I've handled were pre-production test samples.
You've probably already thought of adding a shallow nut on the inside.

You can also just install the other style chain catcher that mounts on the front AV.

Wow! Thanks for all the responses. I have the one that does not mount through the AV mount. But I think I found a solution. I keep a couple bolts and lock nuts for mounting the bucking spike on my 046 in case it works loose in the field. The bolt, although slightly longer, threaded into the 257 perfectly, and I used a little lock tight to ensure it will stay put. If it doesn't work, I'll go back to the dealer and request the other chain catcher!
