• Note: Caterpillar has marked 4P-5711 DISCONTINUED and directs buyers to a dealer for replacement options without naming a number. Core only - tanks, side frames, hoses and hardware are not included. At 1854 mm this is the longest core in the 4P group by a wide margin, sized for the 988 frame and nothing smaller. Ships LTL freight.

Common Use Case or Symptoms:

Replace this when a 988F loses cooling in a quarry or a stockpile and the core has already been cleaned once - a loader this size makes heat faster than a tired core can shed it, and the machine will show it on the gauge long before it drips.

Why Choose Broken Tractor?

• ✅ No Factory Alternative Left: Caterpillar has discontinued this number without naming what replaces it, which puts a working 988F in an awkward position.
• ✅ Longest Core In The 4P Range: 1854 mm, well beyond the 1298 mm and 1316 mm cores used on the smaller loaders - built for the 988 frame.
• ✅ Steel Framed Build: Structural, carbon and alloy steel, matched to a machine that works harder and vibrates more than the mid-size loaders.
