    980G Alarm Fault Lights Issue

    We've tested the machine again, during standstill at higher rpm, the oil pressure catches up to the demand. However, during operation, further testing found that the bucket implements, steering, and braking sometimes gone mid operating. Would this be caused by the pilot pressure unable to catch up?

    CAT 980C brake line pressure question

    CAT 980C SN: 13b01220 Does anyone have a reference that I can check for the brake line pressure for this wheel loader model? Specifically tube PN 3V0040 pressure rating. Was thinking to change it to using hose ~3800psi for ease of installation. Just worried about the pressure rating. Thanks...

    966H LIFTING NO POWER

    Hi Nige, sorry forgot to include, there was no fault code active/recorded when checking with our ET. As for tilt function, we can't really tell if there's any difference in power. However, at the moment, we believe it is also affected since when we tested the pressure, both tilt and lift...
