Re: D9R and 463 pull scraper

I don't have a chart, just made the piston groove a thousands bigger than the o-ring. You don't want it to tight and stretched or it will change the OD of the o-ring. Here's a link to what I...

Re: my attempt at a dozer build

Glad to see you post it ,Neil. Have you tested to see how well it pushs yet?

Re: D9R and 463 pull scraper

Hey Ken, The o-rings are already sized, by that I mean that if you needed an o-ring for a 5/16'' shaft, it is made with the right tolerances that it needs to do the job. When I cut an o-ring grove I...

Re: Servo help

The servo goes to the valve and is lying completely by it self and as soon as the power comes on it moves.

Re: Servo help

The blade (when I first turn on the power switch to the dozer) will move dew to the servo movement. What is causing this?

Servo help

When I turn on the power to my dozer, some of the servos move and then go back to where they were. How do I get them to not move until I move them?

Re: D9R and 463 pull scraper
