Stihl MS170/180 DIY chain catcher

[KostasVolos]

Cutting a lot of brush and thin branches ,
can cause multiple cases of chain derailment .
In short time the plastic chain catcher,
which is built-in on the clutch cover waves
bye-bye for good .
Either a new clutch cover is needed to replace the "chain catcher-less " one or that plastic
chain catcher add on from Stihl is needed
( part # : 1123-656-7700 ) .

Or a round piece of 20 mm dia. Nylon #6 can be
used along with a M5 bolt & nut and couple of washers for an easy and rather robust fix .

Is the nylon available at most hardware stores? I need to do something similar for another saw.

He is in Greece. What hardware stores do you have in ur area? Try looking for nylon spacers or nylon round stock.

 

[KostasVolos]

Here in Greece one can find different material in rods or bars at large hardware shops.

But even if your local hardware shop does not
have any ,you can always order some online.
Just search " Nylon 6 rod " .

Plenty of places to buy from ,for example :

And when it breaks that part of the case off?

Drill a hole in the bottom of the spikes, aka the 660's etc and mount it on that.

Stihl and Husky have both been doing stupid things with homeowner chain catchers for a really long time. If anyone needs an easily-replaceable chain catcher, it the homeowner.

Echo is bad, too...not sure how long they have been at it.
