Dealer reckons the second is a  part for a newer version of the saw?

 

  Anyone have more infos is it an improved design how do I know which one I have already?

[wyk]

Sounds like a Q for @shavey

[shavey]

The part number you need is 161791-9  teal cover

the Dolmar red cover is 161792-7

 

they cost approx £10-£12 +vat

161792-7  says for long chain tensioner pin

 

161792-7 USA: 2017-02 =>KETTENRADSCHUTZ KPL. ROT (FÜR LANGEN ZAPFEN)

 

Had problems with the tension slide pins being weedy and getting knackered

(worn & bent) got through 3 or 4 so far. So it does sound like a an improved upgrade design to accomidate a longer pin.

 

Makes sense to get that version and  a new improved tesion slide pin also. Assuming they fit on the ea4300 as well as the dolmar 420sc.

 

Not sure the teals brethens cover one  has this newer version?

The longer pin shouldn’t make any difference to the side cover I’ve chopped and changed from red too blue covers and never had any problems 

 your chain tensioner shouldn’t be breaking there pretty robust here’s a couple of

points that should help

1. make sure your bar nuts are loose enough before you turn the adjuster screw

2 make sure your chain catcher isn’t bent or comprised as it affects the depth the cover fits into the frame as shown in photos 2 and 4

 

the adjuster pin runs along a groove in the chain cover so it can’t go out of the place 

it sits and has a good travel length as in photo 3

 

photo one shows the chain catcher and a standard chain cover

Thanks really helpful i'll check that stuff out^

 

Still don't understand why they made a rectangle chamfered ended  pin though to fit a round bar hole...... ?

Im still im knacking thoose pins up, im on my 5th  pin.

 

Want a new bar was gonna order this but then realized it wrong mount even though auto selector recommends it? (also the one on the oregon site does also.)

150MLBK041 oregon is what i have atm. The above is k095

 

 

 

So seems options with 15" bar is limited to 150MLBK041?

I got a echo 440evl that uses a K041 mount bar, what tools do i need to convert a K095 bar to work on it?

The answer seems to be the oiling is through the spare tensioner hole on K041 so you would need to modify the K095 bar but it can work.
