New to group, have run my Case 450B on ranch for years. First of many questions as I know next to nothing about Cats or excavators. Recently acquired a Cat 312 S/N 7DK02085 that had a fire in the hyd. area. Burned all the wires and small hoses. I have a parts book and service manual but they leave something to be desired. I need to swing the unit about 90 degrees to get to the wiring. Ser. Man. says I can pressurize the brake port on valve to motor and disengage brake and allow unit to free wheel. True or not? Also are the fittings American or metric?
