Just to clarify if I may. Standard spline is smaller than large spline. Large spline fits 066/660, standard spline fits 044/440.
Some 036s are still microspline if it has the smaller 10x13x10 bearing. With the upgraded 10x16x12 bearing and sprocket, they use standard spline.

044/440 uses same rims as 066/660. Large/standard is one in the same size. There is large/standard, small, and stihls proprietary micro spline.

Most call the sprocket that fits (044, 066, 088, 372, 390, 395) a "standard".

Then there's "small" that fits smaller Huskies, and the Oregon replacements for small stihl.

And then "micro" is the smaller Stihl stuff

What he said.

Hmmm. OK.

Good deal Al, glad to see that Hybrid running again!

that’s what hydraulics are for

And sprocket size affects the oil rate too, so big sprockets don't go with big bars in that sense.

You get the same amount of oil with a 7 or 8 pin. People get confused and think larger sprocket you get more oil. Nope... just more chainspeed. The oil pump worm driver and stroke of the pump determines max output. So your actually wearing the bar and chain faster with a 8 pin... because it’s getting the same oil output as a 7 pin with increased chain speed.

 

[RI Chevy]

So you always oil better with a smaller rim?

 

[huskyboy]

Yes

 

[huskyboy]

Some saws oil output is enough to handle the increased chainspeed and some not so much. I find a 24” 3/8 with a 8 pin needs about the same oil as a 28” 3/8 with a 7 pin for example.

 

[RI Chevy]

Interesting. TY

I meant the sprocket affects the effective oil rate, not the pump volume rate, but oil per chain distance traveled, kinda the same as far as the chain is concerned. Plus if you cut more wood with fewer RPMs with a bigger sprocket, then your oil lasts longer, according to the amount of wood cut, as if the oil rate was decreased.

A larger sprocket does not improve oil output, if that’s what your saying?

I do think some saws can benefit from it depending on what your doing and the bar length/chain used. Especially a 90cc with a short bar. Some of the older big saws can benefit too, they don’t have a lot of rpms, have a lot of torque and can use more chainspeed.

In theory. Come move a whole round to the splitter.

 

[MustangMike]

Since a 7 pin will maintain more RPMs in the cut, it will provide more oil, and the 7 pin will give less chain speed, so your B+C will thank you … 8 pin is harder on stuff … faster chain speed and less oil.

I agree with you Al … I have found it is easier to noodle with my saw than convert to splitter to vertical. I will half it, or quarter it, or whatever it takes, then just lift it into the splitter in horizontal mode. It goes much faster also.

I was implying the chain runs dryer with a bigger sprocket

I agree with that for sure
