Engine Piston 13101-30020 1310130020 For TOYOTA 1KD-FTV Hilux Land Cruiser Prado Fortuner Hiace — Verified OEM Direct Fit, 96mm STD Alfin Oil-Gallery Diesel Piston Set

The Engine Piston Assembly with OEM number 13101-30020 / 1310130020 is a verified direct-fit replacement for TOYOTA 1KD-FTV diesel engines. This piston is a critical reciprocating component responsible for converting combustion pressure into crankshaft rotation and managing thermal load within the cylinder. The 1KD-FTV is a 2,982 cc water-cooled inline-4 DOHC 16-valve common-rail turbocharged diesel engine with a 96.0 mm bore and 103.0 mm stroke, widely used in TOYOTA Hilux, Land Cruiser Prado, Fortuner, and Hiace models from 2000 onward.

• Dimensional Verification: Piston diameter 96.00 mm, compression height 49.6 mm, total height 77.6 mm, pin size 34 mm, combustion chamber diameter 47.85 mm, bowl depth -16.3 to -17.7 mm — verified against OEM drawing specifications for the 1KD-FTV platform.
• Ring Groove Geometry: Ring grooves sized 2.0 mm (top, Keystone) / 1.5 mm (second) / 3.0 mm (oil control) — matched to OEM 1KD-FTV piston ring specifications.
• Material & Construction: Manufactured from aluminum alloy with Alfin insert for ring-land reinforcement, oil cooling gallery, and anodized piston head for improved thermal resistance and scuff resistance. Available as cooled (with oil gallery) or non-cooled version.
• OEM Cross-Reference Verified: Replaces 13101-30020, 13101-30020-01, 13101-30020-02, 13101-30020-03, 1310130020, 13103-30020, 13104-30020, 13105-30020. International brand cross-references include 46675AG STD (TEIKIN), 46675AG.050 (TEIKIN +0.50), MP01091 (Euro4x4parts), PN34430 (Autowelt), EPN1223 (All4Motors).
• Multi-Platform Application: Confirmed compatible with TOYOTA Hilux (N140/150/160/170/190), Land Cruiser Prado (J90, J120, J150), Fortuner (AN50/60), Hiace (H200), and Dyna models equipped with 1KD-FTV engines.

• Cracked piston crown or bowl edge — 1KD-FTV Known Issue: The 1KD-FTV engine, particularly Euro 4 versions (2006–2013), is known for piston cracking at the bowl edge. This is often triggered by worn injectors over-fuelling the cylinder, causing thermal stress and crack propagation. If a violent knocking noise appears and the engine drops a cylinder, piston failure should be suspected immediately.
• Loss of engine compression: Worn or stuck piston rings reduce cranking pressure, causing hard starting and noticeable power loss under load.
• Excessive exhaust smoke (blue/white/black): Indicates oil passing rings or incomplete combustion — top-end refresh often resolves it.
• Increased oil consumption: Glazed bores or tired ring packs allow oil to enter the combustion chamber, raising operating costs.
• Piston scoring or scuffing: Visible skirt wear or liner wall scoring caused by thermal expansion, insufficient lubrication, or overheating.

Kolbenschmidt catalog confirms fitment for Hilux Pickup VI/VII, Land Cruiser Prado II/III/IV, and Fortuner (AN50/60) platforms. Euro4x4parts confirms fitment for Landcruiser series 90 (KDJ90, KDJ95) 2000–2002. NPR (Nippon Piston Ring) confirms fitment for Hilux Vigo, Hiace KUN26, and Land Cruiser Prado KZJ95. Partsouq confirms the piston assembly (13101-30020-01) fits Land Cruiser 90 KDJ9# models from 2000-08 to 2002-09.

Manufacturing conforms to ISO/TS16949 and ISO9001 quality management system standards. Each set undergoes 100% quality inspection before packaging.

1. Verify fitment: Confirm ring widths (2.0/1.5/3.0 mm) and bore diameter (96.00 mm) against removed OEM rings.
2. Check cylinder bore: Measure cylinder bore for wear, taper, and out-of-roundness. If wear exceeds OEM limits, oversize rings (+0.50 mm or +1.00 mm) may be required.
3. Check ring end gap: Insert each ring into its cylinder and measure end gap with a feeler gauge. Compare against manual specification.
4. Ring installation: Install rings with correct orientation (top ring marking up); use a ring expander to avoid breaking rings.
5. Stagger ring end gaps: Position end gaps at 120° intervals around the piston to prevent compression blow-by.
6. Lubricate: Coat rings and cylinder walls with clean engine oil before piston installation.
7. Piston installation: Use a ring compressor to install piston and ring assembly into the cylinder bore.
8. Check ring side clearance: Verify ring side clearance in piston grooves meets OEM specification.

• 1KD-FTV engine oil capacity: approximately 6.9–7.5 L including filter. Replace engine oil every 10,000 km or 12 months, whichever comes first.
• Inspect compression and oil consumption at every 50,000 km or annually.
• Replace piston rings and inspect pistons during any top-end overhaul.
• Monitor timing belt and tensioner condition — replace according to TOYOTA service interval (typically every 150,000 km or 10 years).
• Use only Toyota-approved engine oil (5W-30 or 0W-30 API CJ-4) to ensure optimal ring life and engine performance.

• Standard packing: Neutral packaging / corrugated carton; 1 set (4 cylinders) per box; wooden pallet available for bulk orders.
