Strange chain tension issue.

[Mark_Skyland]

Sorted the problem today. To cut to the chase the sprocket cover was damaged which was causing the bar to pinch the chain. I will go into some boring detail later when I have a bit of time.

The long winded version.

 

Slackened off the chain so its hanging a lot and after a bit of messing about I could see that the chain was getting pinched at the top of the guide bar. I turned the bar and it did the same thing, the sprocket cover and guide plate (this thing in case people are wondering what it is

In this photo you can see the cover was scored along the top probably due to a thrown chain. )

 

Although the surface didn't feel raised I gave it a bit of a tickle with the angle grinder and boom, job done.

 

The amount of material that I removed was next to nothing but enough to cause an issue that I haven't came across before.

 

BTW Im not going to tell the customer that I repaired the cover I'm going to just bang a new one on for the handsome sum of £92 quid. 

 

 

I hope he doesn't use Arbtalk!

That's the old "hitting X with hammer £1, knowing where to draw X £999" story in action.

 

Offer to sell him a refurbished cover for £50 ? Then he should come back next time the saw breaks.

I was only joking. I charged £20, he's a good customer and I learned something.
