    Cat 938H starting problem

    The rebuilder I used for many years retired. Trying to find a good one but not having much luck. One does not work on anything for Caterpillar, another says they can't get parts but can get a new one. Not many around here.

    320CL throttle cable adjustment

    Hi all Working on a Cat 320CL, S/N PAB05835. I Did the governor calibration but it's not showing success. It gives a message of pitch 3. I think that means a loose cable but I'm not sure if my memory is correct. Which cable would need adjustment, accelerate or decelerate ? Thanks.
