Hi all. It has been a while since I posted here. Anyway after much work need assistance on a problem I am having. I purchased a cat 973 s/n 86G
which was sold because it would not move. We have been troubleshooting and have now found out we are unable to get charge pump pressure to the brakes. We ran a line from charge pressure test point to the brake line directly and then the machine moves only in front. We have change filter, using SAE10. We took out the spool valves in the main control valve and cleaned, eventhough looked OK. Any ideas would be appreciated.
