    Got a question. What are the torque specs for those motor mounts? The two bolts that mount the motor to the mount? I don’t want to just send them home and then way over torque them

    Procedure attached.
    If you upgraded the vertical bolts to 3/4 they should be north of 250ft/lbs.
    For most shops all the bolts get stalled out with a 1/2 impact

    Coolant in the oil. Liner orings are rock hard and broken. Bonus points for engine identification.

    Nope. Only 2 valves per cylinder and it aint a paccar truck.

    We honestly have no business working on it but one of our techs is very familiar with the engine and we do lots of other work for the customer.

    Cummins 8.3 in a farm tractor.

    Cummins uses 2 valves per cylinder then.

    Been years, thought one was constant throttle valve. It was just a guess. Rod/liner doesn't look Cummins.
