Thanks bud. I run a g660 on my logosol mill with a 20 inch bar and the factory oil pump was anemic at best. I followed your walk through and woah did it make a difference. I’m a welder so I have all kinds of sanders and grinders, but I found using the file that comes with a raker gauge worked great. Since it has no cutting edge on the thin sides it’s easy pin point where you’re removing material.

Howdy Mitch, Excellent video I've ben logging for 20 years with a old 230D Timberjack and 660s it never crossed my mind to modify the oil pump so thank you for sharing your video

Awesome video bud. Cheers.

I've noticed that the pinion return springs on some farmertec oil pumps are not as stout and can cause the pinion to float at higher rpms and not pump as well in the cut

Awesome 👌 video sir 👏

How did you get the brass plug out of the end of the oil pump? At the end of that long shaft with the ramp angled gear on it
