Superseding & Cross-Reference Numbers:

• Caterpillar publishes no replacement or superseding number for 334-7677.
• The H Series equivalents are different numbers and different metal: 2565310 (256-5310) and 3498238 (349-8238) are aluminium cores for the 950H and 962H. A G II core does not fit an H Series machine.

Key Notes:

• Part Number: 3347677 (Caterpillar reference 334-7677)
• Type: Radiator core assembly - core only, no tanks or frame
• Dimensions: 1359 mm x 470 mm
• Material: Alloy copper
• Weight: 128.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces the radiator core on Caterpillar 950G II and 962G II wheel loaders
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: Core only - tanks, side frames, hoses, cap, shroud and hardware are not included. This core is alloy copper rather than aluminium, which means a radiator shop can solder and re-core it by conventional methods. Ships LTL freight; inspect fins and tube ends before signing for delivery.

Common Use Case or Symptoms:

Fit this when a G II loader loses cooling capacity in a hot pit, when the core has been rodded once already and is weeping again, or when years of washing have eaten the fins back from the face - a copper core hides its condition well until it is pressure tested.

Why Choose Broken Tractor?

• ✅ Copper Not Aluminium: Alloy copper as Caterpillar built it, which solders and repairs by conventional radiator shop methods that will not work on an aluminium core.
• ✅ Largest Face In This Batch: 1359 by 470 mm, sized for the G II loader pack rather than adapted from a smaller machine.
• ✅ G II Not H Series: The H Series loaders take different aluminium cores entirely, and the listing names them so the wrong generation does not get ordered.
