Part Number: 1634057 (Caterpillar reference 163-4057)
Type: Modular radiator core section - one module, not a complete radiator
Construction: Caterpillar Advanced Modular Cooling System module
Dimensions: 1491 mm x 147 mm
Material: Carbon steel and alloy mixed metal
Weight: 36.4 lbs.
Condition: Aftermarket replacement part
Application: Replaces an AMOCS radiator core module on Caterpillar D9R and D10T track-type tractors
Shipping Restrictions: Ships to the lower 48 US states only
Note: This is ONE module. End tanks, seals, spacers and hardware are not included. Two other Caterpillar modules share this exact footprint and fit different tractors - confirm by machine model, and check the module weight, before ordering. Ships LTL freight.
Common Use Case or Symptoms:
Fit these when a D9R or D10T is dropping coolant from one strip, or when the pack has been packed solid with fines that will not blow out - a plugged module in a stack starves the ones behind it, so the machine loses more cooling than one strip should account for.
Why Choose Broken Tractor?
✅ Lightest Of The Matched Three: 36.4 lbs against 38 and 45 lbs for the two modules that share its published dimensions - the practical way to confirm on the bench.
✅ D9R And D10T Only: Catalogued to these two tractors, which is what separates it from the otherwise identical strips.
✅ Single Strip Repair: Modular design means the intact sections stay in the machine and only the damaged one is bought.
