    140G front wheel leak

    A friend of mine recently bought a 140G AWD Serial number 72V14969. It has a leak on the front right wheel. I removed the full plug and it was way over filled.

    Cat 955 L

    Rod is straight but the shop mechanical said that it could be shorter than it should as a result of the impact. I will get a new Rod as well to be safe Can someone provide me the torque specs of the connecting rods?

    Cat 955 L

    Yep that was the new cylinder head. Like 56wrench predicted i ordered new piston, new valves and 8 new valve springs. Fortunately the liner was unharmed. Because the machine is left in the middle of nowhere, i have to put it together tp move it so overhaul will not be done at the time.
