1.3 or 1.5mm chain gauge

[Mark Bolam]

A fencer I know gifted me a brand new Husqvarna H25 chain because he’d bought the wrong size for his bar.

 

It’s .325 15”, but is 1.5mm gauge rather than the 1.3mm gauge on the X-Cut I’ve been running on my 550.

 

I’ve fitted it temporarily, and it seems to run smoothly on my fairly well worn X-Force bar.

 

Is it compatible, or will the extra 0.2mm cause problems when the chain heats up?

How are you running a 058 gauge chain in a 050 bar, if it actually turns the bar must well worn, it should not turn at all.

That was my initial thinking as well.

The bar is on its last legs tbh.

We run 1.6mm Stihl chain on 1.5mm Husky’s (but only once the bars are worn a bit) without any issue, I can’t see another 0.1mm making much/any difference.

I’ll wear out the current chain then give it a go.

If it doesn’t work It’s new bar time anyway.

Cheers.

Bought a 345 off someone a few years ago, he accidentally (or maybe on purpose... who knows?) put a new 1.5 chain on a nearly new 1.3 bar, they did not work happily together. Had to swap it out straight away. 

Couldn't comment on how much wear and tear they'd need before they match, but I wasn't bothered about finding out.

I think I've heard of people running 3/8 058 on worn 050 bars before, as 050 are more common in the states.

 

If it's running free then there's no excess friction to cause heating, I'd run it and see how it goes.
