Description

CATERPILLAR COMPACT TRACK LOADERS:
• Caterpillar 299D3 C3.8 3.8L Turbocharged Diesel (2010-2020)

CATERPILLAR SKID STEER LOADERS:
• Caterpillar 246D3/252D3/262D3 C3.8 3.8L Turbocharged Diesel (2010-2020)


IMPORTANT:
ROTOR ASSEMBLY (not complete pump housing) for Cat C3.8 DIT — a 3.8L 4-cylinder turbo diesel used exclusively in Cat compact track loaders (299D3) and skid steers (246D3/252D3/262D3). The C3.8 is a relatively uncommon engine — do NOT confuse with C3.3 or C3.4 which use different pumps.

Includes gerotor inner and outer rotors. If your pump housing bore is scored or worn, replacing rotors alone will NOT restore pressure — inspect housing before installing. Failure symptoms: oil pressure normal at cold startup but drops at hot idle. On Cat skid steers, low-pressure shutdown typically activates around 7 PSI — intermittent hot-idle shutdowns are the most common complaint with worn rotors. Clean housing bore thoroughly and inspect relief valve spring before installing.

⚠️ Rotor assembly only — not a complete pump. Inspect housing bore condition.
