Good day, i have a 2006 JCB 3cx backhoe with engine overheating issue.

Quick history: Crankshaft broke, overhauled engine with new standard Crankshaft and bearings. Now all of a sudden engine overheats when driving or working hydraulics. Transmission oil temp light also goes on. Running the tlb in fourth gear stalls engine.

Everything was working fine before. Could the torque converter or Transmission be damaged and causing engine to labour too much? What could be causing this?

Check and see if you have compression in the water if so the head gasket or head is leaking.
