Engine Piston 12010-10T12 1201010T12 For NISSAN TD27 TD27T TD27Ti Atlas Cabstar Caravan Urvan Patrol — Verified OEM Direct Fit, 96mm STD Alfin Oil-Gallery Diesel Piston

The Engine Piston with OEM numbers 12010-10T12 / 1201010T12 is a verified direct-fit replacement for NISSAN TD27, TD27T, and TD27Ti 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 TD27 is a 2,663 cc water-cooled inline-4 OHV diesel engine with a 96.0 mm bore and 92.0 mm stroke, widely used in NISSAN Atlas, Cabstar, Caravan, Homy, Urvan, Datsun Truck, Pathfinder, Terrano, and Patrol models from the late 1980s through the 2000s.

This piston is also compatible with the TD42 4.2L diesel engine platform in certain applications, as the TD27 and TD42 share similar piston specifications in some aftermarket catalogs.

• ✓ Dimensional Verification: Piston diameter 96.00 mm, compression height 50.2 mm, total length 87 mm, pin diameter 28 mm, pin length 80 mm, combustion bowl depth -1.70 mm — verified against OEM drawing specifications for the TD27 platform.
• ✓ Ring Groove Geometry: Ring grooves sized 2.5 mm (top) / 2.0 mm (second) / 4.0 mm (oil control) — matched to OEM TD27 piston ring specifications.
• ✓ Material & Construction: Manufactured from aluminum alloy with Alfin insert for ring-land reinforcement, oil gallery cooling channel, tin coating (tinned alfin) for improved break-in and scuff resistance, and 2 valve pockets for valve clearance.
• ✓ OEM Cross-Reference Verified: Replaces 12010-10T01, 12010-10T02, 12010-10T11, 12010-10T12, 12010-43G01, 12010-43G02, 12010-43G11, 12010-43G12, 1201010T01, 1201010T02, 1201010T12, 1201043G02, 1201043G12. International brand cross-references include 44267A STD (TEIKIN), 44267 STD (TEIKIN), PN-33250 (Autowelt), 1N96010T (TIK).
• ✓ Multi-Platform Application: Confirmed compatible with NISSAN Atlas (AF22, AGF22, AH40, AMF22, P2F23, P4F23, P6F23, P8F23, PGF22), Caravan (CRGE24, CRMGE24, DRGE24, KRE24, VRE24, VRGE24, VRMGE24), Civilian (RAW40, RGW40, RW40, RYW40), Datsun Truck (BD21, BGD21, BMD21), Homy (CRGE24, CRMGE24, DRGE24, KRE24, VRE24, VRGE24, VRMGE24), Pathfinder, Terrano, Urvan, and Patrol models.

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

Manufacturing conforms to ISO/TS16949 and ISO9002 quality management system standards. Each unit undergoes 100% quality inspection before packaging. Production adheres to GB1148-82, JB3931-85, and JB3932-85 piston standards.

1. Verify fitment: Confirm piston diameter (96.00 mm), compression height (50.2 mm), and ring groove dimensions (2.5/2.0/4.0 mm) against removed OEM piston.
2. Check piston-to-bore clearance: Measure cylinder liner bore and piston skirt diameter; compare against manual specification.
3. Ring installation: Install rings with correct orientation (top ring marking up); stagger ring end gaps at 120° intervals.
4. Pin & clip installation: Lubricate pin bore and install piston pin (28 × 80 mm); secure with new circlips (included in set).
5. Connecting rod torque: Follow manual sequence — always confirm against the specific engine variant manual.
6. Liner protrusion: Verify liner protrusion meets specification before final assembly.

• Inspect compression and oil consumption at every 50,000 km or annually, whichever comes first.
• Replace piston rings and inspect pistons during any top-end overhaul.
• Monitor coolant condition and injection pump timing — the TD27 indirect injection system is sensitive to fuel quality and pump calibration.
• Replace timing belt and tensioner according to NISSAN service interval (typically every 100,000 km or 5 years).

• Standard packing: Neutral packaging / corrugated carton; 4 pcs in one set (for 4-cylinder TD27 engine); wooden pallet available for bulk orders.
• Set options: Piston only, or piston set with pin & circlips — specify at inquiry. Rings available separately.
• Minimum order: 4 pcs (one engine set) per order; bulk quantity discounts available.
• Supply capacity: Stable monthly supply.
• Suitable for: Engine rebuild workshops, fleet maintenance departments, spare parts distributors, and export wholesalers.
• Related parts available: Piston ring set (2.5+2.0+4.0 mm), cylinder liner kit (96 mm), piston pin (28 × 80 mm), circlips, and full TD27 overhaul kit.
