2382698 Engine Rebuild Kit for Caterpillar C7 In‑Frame Engine – Complete Overhaul Solution
1. Basic Specifications & Key Parameters
The 2382698 engine rebuild kit is a complete in‑frame overhaul solution designed specifically for the Caterpillar C7 diesel engine (ACERT and pre‑ACERT variants). This kit allows a full rebuild while the engine remains in the chassis – no need to remove the engine from the vehicle or equipment, saving significant labor time and reducing downtime.
Base Engine Specifications (Caterpillar C7):
Displacement: 7.2 L (439 cu in)
Bore × Stroke: 110 mm × 127 mm (4.33″ × 5.00″)
Cylinder configuration: Inline 6‑cylinder, 4‑stroke, turbocharged & aftercooled
Fuel system: HEUI (Hydraulically actuated Electronic Unit Injection) with ACERT technology
Compression ratio (stock): 16.5:1 (turbo) / 17.5:1 (naturally aspirated)
What the 2382698 In‑Frame Rebuild Kit Includes:
6 x wet‑type cylinder liners (centrifugally cast gray iron, induction‑hardened bore, plateau cross‑hatch finish)
6 x forged aluminum pistons (with internal cooling gallery for ACERT/turbo versions)
6 x piston ring sets (plasma moly top ring, tapered second ring, 3‑piece steel oil ring)
Piston pins and retaining rings
Main bearings (tri‑metal – steel back, copper‑lead, tin‑babbitt) – standard or undersize
Connecting rod bearings (tri‑metal)
Thrust washers and camshaft bearings
Full upper & lower gasket set – MLS (multi‑layer steel) head gasket, valve cover, oil pan, intake/exhaust manifold, turbocharger, timing cover, water pump seals, all O‑rings, injector seals, copper washers, front & rear crankshaft seals
Piston cooling jets (where applicable)
Valve stem seals
Connecting rod bolts (torque‑to‑yield type – must be replaced)
All components meet or exceed Caterpillar OEM specifications. The kit is available in standard size and oversize bearing sets (0.010″, 0.020″, 0.030″) to match reground crankshafts.
Part number 2382698 is the OEM / aftermarket reference for the complete C7 in‑frame kit. Always verify your engine serial number prefix (e.g., C7S, C7E, C7T, C7B, etc.) before ordering.
2. Compatible Vehicles & Equipment
The Caterpillar C7 engine (often referred to as the 3126 successor with ACERT) is widely used across medium‑duty trucks, buses, RVs, construction machinery, and industrial equipment. The 2382698 rebuild kit is suitable for any application powered by a Caterpillar C7 engine.

3. Performance Advantages & Functional Improvements
Installing the 2382698 complete in‑frame rebuild kit restores the Caterpillar C7 engine to factory‑fresh operating condition. Here are the key performance gains you can expect:
✅ Restored Compression & Full Power
New liners, pistons, and rings seal combustion gases perfectly. Cranking compression returns to 350–450 psi across all six cylinders (factory spec). The engine recovers its rated torque and horsepower – no more struggling on hills or under heavy loads.
❌ Elimination of Blow‑by
Worn rings and polished liners allow combustion gases to escape into the crankcase, causing blow‑by. The new plasma‑moly top rings provide exceptional sealing, reducing crankcase pressure to near zero. You will notice no more vapor puffing from the oil fill tube or dipstick.
⛽ Drastically Reduced Oil Consumption
A worn C7 can consume 1 quart of oil every 50–100 hours. After a proper in‑frame rebuild using this kit, oil consumption drops to less than 0.5 quart per 500 hours. Blue exhaust smoke disappears, and you no longer need to top up oil between changes.
📈 Improved Fuel Economy
Restored cylinder compression and proper air‑fuel mixing increase thermal efficiency. Many owners report a 10–20% improvement in fuel economy after rebuilding with a quality kit – quickly recovering the cost of parts.
🔧 Healthy Oil Pressure
New main and rod bearings restore oil clearances to the ideal 0.002–0.003″ range. Hot idle oil pressure rises from a dangerous 10–15 psi to a healthy 25–35 psi. At working RPM, pressure returns to 45–65 psi – protecting the turbocharger, camshaft, crankshaft, and HEUI pump from premature failure.
🔇 Smooth & Quiet Operation
New pistons, rings, and bearings eliminate knocking, rapping, and uneven running. The C7 runs with a steady, balanced cadence – reducing operator fatigue, vibration, and noise.
⏳ Extended Service Life
A quality in‑frame rebuild using the 2382698 kit can extend the life of your C7 engine by 8,000 to 12,000 operating hours or 300,000 to 500,000 miles in on‑highway applications, depending on maintenance and operating conditions.
🛠️ HEUI System Compatibility
The kit includes high‑quality injector seals and O‑rings specifically designed for the HEUI fuel system. Proper sealing prevents high‑pressure oil leaks and ensures consistent injection pressure.
