Key Notes:

• Part Number: 4P0894 (Caterpillar reference 4P-0894)
• Type: Multi row module radiator core - core only, no tanks or frame
• Dimensions: 1316 mm x 267 mm
• Material: Carbon steel, structural steel, alloy steel and alloy copper
• Weight: 48.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces the radiator core on Caterpillar D6H and D7H dozers, 966D and 966E wheel loaders and the 815B soil compactor
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: Caterpillar has marked 4P-0894 DISCONTINUED and directs buyers to a dealer for replacement options without naming a number. Core only - tanks, side frames, hoses, cap and hardware are not included. At 267 mm this is the deepest core in the 4P group, nearly double the 145 mm modules used on the F Series machines. Ships LTL freight.

Common Use Case or Symptoms:

Order this when a D6H or D7H will not hold temperature under blade load, or when the core is weeping after a second rodding - a dozer working in timber packs its core with chaff and bark, and once the fins are eaten back no amount of cleaning restores the cooling.

Why Choose Broken Tractor?

• ✅ Cat Has Retired The Number: Caterpillar lists this core as discontinued with nothing named to take its place, which is where an owner of a running D7H usually gets stuck.
• ✅ Deepest Core In The Group: 267 mm front to back, against the 145 mm and 149 mm modules on the newer machines - a tape measure settles it instantly.
• ✅ Dozers Loaders And A Compactor: Five D6H and D7H variants, two 966 loaders and the 815B soil compactor on one core.
