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 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: Cat 777D Mining Truck
Tom, those tires look like you just got a delivery from GoodYear. They look good on the rims also. Have you started on any of the rest of the truck yet?
