Oil holes

[peterk]

Could someone throw some light on these grooves in this carving bar?

I presume the holes I marked with red arrows are the oil holes.

What are the grooves I marked with green arrows?

All contributions are welcome.

Many thanks - Peter

I would have thought its for chain tensioners on drifferent brands of saws, so instead of it just for stihl or just husky they fit both with no oiler and tensioner issues? maybe just a guess

I think you are right. The slids at the blue arrows are for oil.

 

Two ways of telling for certain:

 

1. Confirm if there is a way for oil to go from the holes at the red arrows and into the bar groove
   
2. Mount the bar and have a look at which of the holes/slids match up with the oiler groove on the saw body

Thats exactly what I thought, a single bar for a number of tensioners - if any of the large holes are oiler holes, they will have through holes to the bar rails!

 

Reckon Ben is correct on this one

yeah red arrows chain tensioners and green oilers as the chain would bypass the green holes and drivelinks channel oil round the bar

Zebra carving bars are universal fit for most saws up to 60cc. Apparently they sometimes need a bit of fettling to fit some saws. They take a 1/4 chain.

OK, then, not quite blue, but I couldn't spell "turquoise" at the time. But we could also just call it green, which I guess would be more accurate

 

Guess I should make an appointment with my local optometrist

Where'd you get that bar from Peter?

 

 

The zebra bars are a budget option. They work fine but do not last as long as the Cannon/Oregon equivalent. It's a cheaper way to get into carving.

 

However the recent batch last sent from the factory was minus the oiler holes. Without the correct gear to drill the oiler holes the importer of these found it easier and more efficient to grind them.

 

So the green holes are oiler holes and the red holes are the universal holes for tensioning the bar (although on some saws one of these can also act as an oiler hole as well).

Thanks Rob. The photo is from their web site and I could not understand the notches. I have never seen oiler notches before.
