Key Notes:

• Part Number: 1634061 (Caterpillar reference 163-4061)
• 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: 45.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces an AMOCS radiator core module on Caterpillar track-type tractors from the D6R through the D10R
• 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, and a fourth number covers a subset of this one's machines - confirm by machine model and module weight before ordering. Ships LTL freight.

Common Use Case or Symptoms:

Reach for these when a D6R through D10R is weeping from one section of the stack, or when a strip has been holed by debris - the stack keeps working with a damaged module in it, which is exactly why they get run until the coolant loss becomes a daily top-up.

Why Choose Broken Tractor?

• ✅ Ten Tractor Coverage: The broadest fitment of any module in this family, from the D6R through the D10R.
• ✅ Heaviest Of The Matched Three: 45 lbs against 36.4 and 38 lbs for the two modules sharing its published dimensions - a reliable bench check.
• ✅ A Narrower Number Overlaps: 163-4062 covers only three of these tractors, and Caterpillar shows the two together - the listing says so rather than leaving it to chance.
