Stihl MS660 Knock Knock Joke

Customer complaint of this Stihl MS660 chainsaw is that it won't start. I believew him but thats not really the whole truth and this saw is hiding a dark secret. #smallenginerepair

I have experienced something similar with a Husqvarna 346 XPG. With that saw I suspect that a small air leak caused the bottom rod bearing to fail after long use, possibly due to lack of proper lubrication. There was significant backlash turning the flywheel back and forth and no start. Some small parts of the needle bearing found its way through the exhaust. Quite a few new parts needed, but the cylinder could be reused. With the MS 660, it would be very interesting to follow a tear down of this saw to see the failing parts, but I understand the customer that it can be hard to accept the total cost of such a repair. Thanks for uploading videos and I try to watch most of them.

That's a huge bar. Whats the name of the pointy spikey part on the front of the saw?

[@TheGreasyShopRag]

Around here we call it a felling dog but I'm sure there are different names for it.

[@mitchelrichardson8164]

@@TheGreasyShopRag yeah there is different names for it.. felling dog, dog spike, bumper spike,

I want to see who brought that saw in.

[@markm0000]

First time landlord probably.

[@nightshadefern162]

Strait gassed or over revved? poor thing. Those 660s are beasts.

[@TheGreasyShopRag]

Sometimes I don't get to spend a lot of time investigating "why".

I Had a 660 In My Shop 3-4 Weeks Ago and It Had a Snapped Off Connecting Rod The 1st One I’ve Seen Snap in 20 Years The Piston Was Frozen In The Bore The Customer Said It Revvvved Up Then Died Wont Restart 😩😬🙁🙁😬

[@TheGreasyShopRag]

I've seen bent ones but never snapped. Ouch$

[@steveriggenbach90]

Is that common with that model? Could the owner have caused it? Happy Easter. Take care.

[@TheGreasyShopRag]

This is the first 660 I've seen with a failed lower rod bearing but these big saws aren't the norm around here. You'd need to ask a west coast mechanic that question. Happy Easter.

@@TheGreasyShopRag thanks I’ll try finding someone. If he used it with a backwards chain, it saw a ton of shocks.

Typical homeowner, it won’t start! L O L
