Elementor #17201

📦 Components Included in This Overhaul:

• Cylinder liners (wet sleeves)

• Pistons, wrist pins, and circlips

• Piston rings

• Main bearings (upper and lower)

• Connecting rod bearings

• Thrust washers

• Complete overhaul gasket kit

🧰 Step 1: Preparation

Tools Required:

• Torque wrench (in lb-ft/N·m)

• Piston ring compressor

• Liner puller/installer

• Dial bore gauge

• Micrometer & plastigage

• Engine hoist or lifting bracket

• Clean workbench

Safety:

• Disconnect battery.

• Drain coolant, oil, and fuel.

• Tag all hoses and wiring for easy reassembly.

🛠️ Step 2: Engine Disassembly

1. Remove external components:

   • Turbocharger, intake/exhaust manifold

   • Fuel lines, injectors

   • Water pump, fan, serpentine belts

2. Remove valve cover, rocker arms, and pushrods.

3. Remove cylinder head.

   • Loosen bolts in reverse sequence using proper torque steps.

4. Remove oil pan and oil pump.

5. Remove piston/rod assemblies.

   • Note the cylinder numbers on each rod.

6. Pull out cylinder liners using a proper liner puller.

🔍 Step 3: Inspection & Measurements

• Crankshaft: Check for scoring, taper, and out-of-round.

• Main bore and rod bore: Verify clearance using plastigage.

• Cylinder block: Check for cracks, warpage, corrosion.

• Head deck and block deck flatness: Use straightedge and feeler gauge.

• Connecting rods: Check for bend or twist.

📝 If any part is out of spec, replace or re-machine as needed before proceeding.

⚙️ Step 4: Component Installation

🔩 1. Cylinder Liners:

• Clean block bores thoroughly.

• Apply light oil or sealant as required.

• Press-fit liners using installation tool.

• Verify liner protrusion (usually 0.07–0.15 mm) for proper sealing.

🔩 2. Pistons & Rings:

• Fit piston rings carefully (gap positioning ~120° apart).

• Install wrist pin and circlips.

• Use piston ring compressor to insert into liner.

• Ensure piston orientation (usually arrow or mark facing front).

🔩 3. Bearings & Thrust Washers:

• Clean crank journals and bearing seats.

• Install main bearings and rod bearings (note upper/lower orientation).

• Install thrust washers at specified main bearing position.

• Torque to spec in steps. Use plastigage to confirm oil clearances.

🧱 Step 5: Reassembly

1. Install oil pump and pickup tube.

2. Install oil pan with new gasket.

3. Reinstall cylinder head.

   • Use new head gasket from the overhaul kit.

   • Torque in three steps using the factory bolt pattern.

4. Reinstall rocker arms, pushrods, injectors, manifolds, and turbo.

5. Connect all hoses, wires, belts.

🔧 Step 6: Initial Startup & Break-In

🛢️ Fluids:

• Fill with fresh oil and coolant.

• Prime oil system before cranking (hand pump or bypass).

🔁 First Start:

• Crank without injectors to build oil pressure.

• Install injectors and start engine.

• Monitor for oil pressure, coolant temperature, unusual noises, or smoke.

🧪 Run-in Procedure:

• Idle for 15 minutes, then gradually load engine.

• Avoid full throttle or heavy loads for first 20–30 hours.

• Change oil and filter after 50 hours.
