OK, so if I want to run .063 gauge chain on my Makita 6401, do I just need a .063 bar? I know this may be a dumb question but I'm looking for some full skip and .063 is the only size I can find locally (today) ... the saw is currently with .050 .... I guess I'm wondering if A.) it will work B.) what all I need to change to make it work.

Work with me, I'm still learning. : )
 
You are corect. As long as you stay with the same gauge, all you need to change is the bar and chain. If you change gauge you must change the sprocket, bar and chain.

Sawin I think you mean pitch.

If you change the gauge you need to change the bar because the gauge is the thickness of the drive links which match the width of the groove in the bar. If you change the pitch you will also need to change the drive sprocket to match the new pitch.
 
63 gage bar

You will need to match the chain gage to the bar gage. Drive links measure 63 thousandths inch wide (thick?), so bar will need 63 thousandths inch width to enable the fit. Hope this makes sense. Larger gage chain has a stronger chasis and absorbe more HP.

Thanks guys, that is what I thought.

So (to make sure I understand) ... If I were to switch from a 3/8ga to like .325, THEN a sprocket, chain, and bar would be necessary. But as long as I'm using 3/8ga (or 'the same') gauge then the only thing necessary to change is the bar when using a different pitch chain? I hope that made sense. :)
 
After joining this site I now understand about chain pitch and gauge. :cheers:

One thing I don't understand though is my new Husky 365. It came with a 20 inch bar and 3/8 pitch .058" gauge chain. From what I see the 3/8 pitch .050" gauge seems much more popular and easy to get. Why wouldn't Husky just go with the .050" gauge bar and chain on it instead? :confused:

In this region .058" is the standard for Husky and Dolmar, Stihl is the exception

One dumb question!!!!

How could this be a dumb question? I had to ask the very same thing when I first found this site and I know I is smart.

It aint a dumb question, what was dumb was the moron that couldn't properly answer that question, oh, that would be ME:greenchainsaw:
 
But you'll need to use a completely different bar oil than you've been using....If you use the stuff you've been running with a 63 gauge chain...You'll mess the whole saw up...:hmm3grin2orange: :hmm3grin2orange:


Sorry...I couldn't help it.

My dealer doens't even stock the 63 gauge oil. Guess I'll go back to savin' the old oil outta the truck.
