.404 to 3/8 conversion drive links

[jake wells]

I got a 21'' Remington roller nose bar that takes 72DL of .404,,, How many drive links of 3/8 will i need???

Is the 3/8 nose the same size as the 404 nose?

Remington roller nose will take .050", .058" and .063" chain.

Most Remington bars over 20" are .058" gauge.

.404 72 dl is the middle of 3/8 79-80dl according to my measuring gauge. If you have access a breaker and spinner start with 80dl and shorten one dl if needed. Really depends on how much adjustment you have too.

Most 20" 404 bars are 66dl, and 72dl 3/8. A 25" bar has a similar 6dl difference.
72dl 404 is 77.5dl of 3/8 (multiply by 0.404, divide by 0.375), so 6dl difference seems right to me.
I asked about the nose variation because sometimes a 3/8 and a 404 nose are a different profile, I'm assuming you are changing the nose as 3/8 and 404 won't spin over the same sprocket.

It's a roller nose, not a sprocket tip.

Well that makes more sense! Didn't even think of those.
