Part Number: 1634062 (Caterpillar reference 163-4062)
Type: Modular radiator core section - one module, not a complete radiator
Fin Density: 6 fins per inch
Internal Volume: 2 to 3 litres
Flow Rates: 96 litres per minute water, 36.62 kg per minute air
Material: Carbon steel with alloy mixed metals, leak tested at 15 to 18 psi
Weight: 37.0 lbs.
Condition: Aftermarket replacement part
Application: Replaces a radiator core module on Caterpillar D7R II, D8R and D8R II 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. Caterpillar publishes no dimensions for this number, only its thermal figures, so measure the module you are removing. At least two other Caterpillar modules cover these same tractors. Ships LTL freight.
Common Use Case or Symptoms:
Order these when a D8R runs warm through a shift with a clean pack and a proven fan, or when one strip is seeping - at 6 fins per inch this module packs its heat transfer tightly, which also means it silts and plugs sooner than a coarser core in the same dust.
Why Choose Broken Tractor?
✅ Only Module With Published Flow: 6 fins per inch, 2 to 3 litres internal volume, 96 litres per minute of water - figures Caterpillar publishes for almost nothing else in this family.
✅ Pressure Tested Construction: Leak tested at 15 to 18 psi, which is the standard the replacement should be built to.
✅ Narrow Fit By Design: Three tractors only, where the neighbouring module covers ten - the narrower number is usually the more specific fit.
