Engine Piston 13101-30170 For TOYOTA 1KD-FTV Hilux Land Cruiser Prado Hiace Fortuner Dyna 3.0 D-4D — Verified OEM Direct Fit, 96mm STD Alfin Oil-Gallery MOS2 Skirt, 4-Cylinder Set

The Engine Piston with OEM number 13101-30170 is a verified direct-fit replacement for TOYOTA 1KD-FTV (3.0L) common-rail 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 turbocharged common-rail diesel engine with a 96.0 mm bore and 103.0 mm stroke, widely used in TOYOTA Hilux, Land Cruiser Prado, Hiace, Fortuner, and Dyna models from 2011 onward (Euro 5 emission specification).

This piston features an Alfin insert at the ring-land area, an internal oil gallery for crown cooling, and a MOS2 (molybdenum disulfide) treated skirt for superior anti-friction and anti-scuffing performance. The 4-cylinder set is supplied in standard (STD) 96.00 mm size, with oversize options available for worn cylinder bores.

• Dimensional Verification: Piston diameter 96.00 mm (STD), compression height 49.6 mm, total length 78.5 mm, pin diameter 34 mm, pin length 73 mm, recess depth -4.0 / -16.5 mm, bowl diameter 63 mm — verified against OEM drawing specifications for the 1KD-FTV platform.
• Ring Groove Geometry: Ring grooves sized 2.0K mm (top, Keystone) / 1.5 mm (second) / 3.0 mm (oil control) — matched to OEM 1KD-FTV piston ring specifications.
• Material & Construction: Manufactured from high-grade aluminum alloy with Alfin insert for ring-land reinforcement, internal oil cooling gallery, and MOS2-treated skirt for reduced friction and improved scuff resistance.
• OEM Cross-Reference Verified: Replaces 13101-30170, 13101-30170-01, 13101-30170-02, 13101-30170-03, 13103-30170 (+0.50), 13104-30170 (+0.75), 13105-30170 (+1.00), 13101-30172. International brand cross-references include ARCO PKTO40960BDB, TEIKIN 46686AG STD, Autowelt PN-34430, United Motors PC1272000.
• Multi-Platform Application: Confirmed compatible with TOYOTA Hilux (KUN26), Land Cruiser Prado (KDJ150, KDJ155, KDJ120), Hiace (KDH200/201/203/221/223), Fortuner (AN50/60), and Dyna (KDY221/231/251/261) equipped with 1KD-FTV engines.

• 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 — piston and ring replacement 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 — requires immediate replacement to prevent catastrophic engine failure.
• Knocking or tapping noise: Piston slap or bearing wear requires inspection before further engine operation.

Confirmed Fitment Sources: Partsouq Toyota parts catalog confirms 13101-30170-01/-02/-03 fitment for Hilux KUN26 (2011–2015), Land Cruiser Prado KDJ150/KDJ155 (2013–2015), Hiace KDH200/201/203 (2012–2013), and Dyna KDY221/231/251/261 (2011–2015). Racingpeaks catalog confirms fitment for Hilux Pickup VI/VII, Land Cruiser Prado II/III/IV, and Fortuner (AN50/60).

Manufacturing conforms to ISO/TS16949 and ISO9001 quality management system standards. Each piston undergoes 100% quality inspection before packaging. Cold test, hot test, and load verification available with reports upon request.

1. Verify fitment: Confirm piston diameter (96.00 mm), compression height (49.6 mm), and ring groove dimensions (2.0K/1.5/3.0 mm) against removed OEM piston. Verify MARK grade (-01/-02/-03) matches original.
2. Check piston-to-bore clearance: Measure cylinder bore and piston skirt diameter; compare against manual specification. If cylinder bore wear exceeds OEM limits, select appropriate oversize piston (+0.50/+0.75/+1.00 mm) and bore/hone accordingly.
3. Ring installation: Install rings with correct orientation (top ring marking up); use a ring expander to avoid breaking rings. Stagger ring end gaps at 120° intervals.
4. Check ring end gap: Insert each ring into its cylinder and measure end gap with a feeler gauge. Compare against manual specification.
5. Pin & clip installation: Lubricate pin bore and install piston pin (34 × 73 mm); secure with new circlips (included).
6. Connecting rod torque: Follow manual sequence — always confirm against the specific engine variant manual.
7. Lubricate: Coat rings and cylinder walls with clean engine oil before piston installation. Use a ring compressor for piston insertion.
8. Check liner protrusion: Verify liner protrusion meets specification before final assembly.

• 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.
• Oil type: Toyota-approved 5W-30 or 0W-30 API CJ-4 / ACEA E6/E7.
• 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).
• ⚠️ 1KD-FTV 特别注意：2010年前生产的 1KD-FTV 发动机存在活塞开裂的已知问题，建议在进行任何发动机大修时直接更换为改进型活塞（13101-30170 对应型号），避免重复故障。
