Original SANY Assembled Sealing Washer 160102130003A092 Construction Machinery Parts

The genuine SANY parts reference 160102130003A092 is the Assembled Sealing Washer, a bonded metal‑rubber sealing ring used under bolt heads and nuts to prevent fluid leakage in SANY heavy machinery. The 160102130003A092 assembled sealing washer combines a zinc‑plated steel washer with a captive nitrile rubber sealing lip that compresses against the mating surface, creating a leak‑proof joint for oil, fuel, or coolant passages.

Manufactured from case‑hardened steel with a bonded NBR seal, this washer provides excellent corrosion resistance and sealing performance under vibration and thermal cycling. Each 160102130003A092 unit is 100% inspected for rubber adhesion, inner/outer diameter, and thickness, ensuring reliable sealing in SRT dump trucks, SY excavators, SW wheel loaders, and motor graders.

Material and Design of Assembled Sealing Washer 160102130003A092

The assembled sealing washer 160102130003A092 consists of a stamped steel washer (DC01 / 1008 steel) with a bonded nitrile rubber (NBR) sealing ring. The steel outer diameter is typically 22 mm, inner diameter 10.5 mm (for M10 bolts), and thickness 1.5 mm. The rubber sealing lip protrudes 0.5-0.7 mm above the steel face. When the bolt is torqued, the rubber compresses and fills micro‑imperfections in the mating surface.

The steel portion is electro‑zinc plated (5-8 µm) with clear trivalent passivation, providing 96 hours of salt spray resistance (ASTM B117). The rubber is bonded to the steel using a heat‑activated adhesive; peel strength exceeds 20 N/cm. The NBR material has a Shore A hardness of 70 ±5 and is resistant to mineral oils, diesel fuel, coolant, and hydraulic fluids.

The design is asymmetrical: the rubber seal is on the flat side that contacts the clamped part (not under the bolt head). This orientation ensures the rubber compresses against the joint surface, not against the bolt head. The washer also functions as a load distributor, reducing the risk of galling or damaging aluminum housings.

All 160102130003A092 washers are 100% inspected for rubber presence, bond integrity, and dimensions (ID, OD, thickness). A sample from each batch is tested for compression set (≤25% after 22h at 100°C) and oil immersion weight gain (≤10% in IRM 903 oil at 100°C). Batch codes are printed on the packaging for traceability.

Critical Applications of Washer 160102130003A092 in SANY Equipment

The assembled sealing washer 160102130003A092 is used on threaded fasteners that penetrate into oil, fuel, or coolant passages. Typical applications include oil pan drain plugs, transmission filler plugs, fuel injection pump mounting bolts, and water pump housing bolts. It prevents fluid from wicking along the bolt threads and leaking externally.

On SRT dump trucks, 160102130003A092 washers are installed on axle housing fill and drain plugs, differential cover bolts, and hydraulic tank drain plugs. On SY excavators, they seal the hydraulic pump mounting bolts and swing drive drain plugs. The washer is also used on final drive planetary carriers and wheel hub bolts.

For engine applications, 160102130003A092 seals the oil cooler bypass valve bolts and thermostat housing bolts. It is also used on the power steering pump reservoir and fuel filter head bolts. Always replace the washer with a new one whenever the bolt is removed from a fluid‑carrying joint – the rubber takes a compression set and may not seal again.

Compatible SANY Models & Part Interchange

The assembled sealing washer 160102130003A092 is used across SANY’s heavy equipment line: SRT45, SRT55, SRT95, SRT115 dump trucks; SY215 to SY500H excavators; SW305, SW405, SW465 wheel loaders; SMG200/220 graders; and STC crawler cranes. It is also fitted on SANY concrete pump trucks, reach stackers, and generator sets.

The washer fits M10 bolts (inner diameter 10.5 mm). Always verify the original washer size. The rubber seal is designed for single use only. Do not substitute with a plain flat washer or a copper crush washer – the bonded rubber lip provides superior sealing under vibration.

For fleet maintenance, stock genuine 160102130003A092 washers. Aftermarket seal washers often lack proper rubber‑to‑steel bonding or use low‑grade nitrile that hardens quickly. Genuine SANY washers guarantee the correct dimensions, rubber compound, and zinc plating for reliable leak prevention.

Proper Installation of Assembled Sealing Washer 160102130003A092

Before installing the sealing washer 160102130003A092, clean the bolt shank and the mating surface on the component. Remove any old sealant or gasket residue. The washer should be placed with the rubber side facing the component (not the bolt head). The steel side contacts the bolt head or nut. This orientation allows the rubber to compress against the joint surface for maximum sealing.

Do not reuse a sealing washer after it has been compressed. The rubber takes a permanent set and will not seal again. Always use a new 160102130003A092 washer whenever the bolt is removed. Tighten the bolt to the torque specified in the SANY manual (typically 25-30 Nm for M10 bolts). Over‑torquing can extrude the rubber and damage the washer.

After tightening, inspect for any fluid seepage around the bolt head. If a leak is detected, do not tighten further – remove the bolt and inspect the washer. The rubber may be damaged or missing. Replace with a new 160102130003A092 and re‑torque. For drain plugs, it is good practice to replace the washer at every oil change.

Store new washers in a cool, dry place away from UV light and ozone. Shelf life is 5 years. Do not store near electric motors or welding equipment. Always order genuine SANY washers – aftermarket products may have poor rubber adhesion or incorrect dimensions.

Symptoms of a Failed Sealing Washer 160102130003A092

A failed 160102130003A092 washer typically shows signs of fluid wetness around the bolt head or nut. On an oil pan drain plug, you will see oil dripping from the plug after an oil change. On a fuel filter head, you may smell diesel or see wet stains. A small leak can escalate over time as the rubber continues to harden.

If the washer was installed with the rubber side facing the bolt head (incorrect orientation), it will not seal and may leak immediately. The steel side does not conform to surface irregularities. Also, if the washer was reused, the rubber will be visibly flattened and may have cracks. Always replace after removal.

In extreme cases, a missing or damaged seal washer can allow fluid to escape rapidly, leading to low oil pressure or fuel starvation. During engine disassembly, inspect every 160102130003A092 washer for rubber deterioration. If the rubber is hard, brittle, or missing, replace all washers on that joint.

Quality Assurance & Full Traceability for 160102130003A092

Every assembled sealing washer 160102130003A092 is manufactured in an IATF 16949 certified facility. The steel stamping process is followed by zinc plating and then rubber injection molding. Bonding is achieved using a heat‑activated adhesive. In‑process checks include rubber hardness, adhesion peel tests, and dimensional inspection using optical gauges.

A sample from each production batch is tested for compression set (ASTM D395) and oil immersion swelling (ASTM D471). Salt spray testing (96 hours) verifies the zinc coating integrity. Each batch is assigned a unique lot number printed on the packaging, providing traceability to the raw material certificates and molding parameters.

For bulk orders, SANY provides a Certificate of Conformance (CoC) confirming that all 160102130003A092 washers meet material, dimensional, and performance specifications. Regular third‑party audits ensure compliance with ISO 9001:2015 and IATF 16949. Use only genuine SANY washers for guaranteed leak prevention.

Field Performance of Genuine SANY Sealing Washer

Field data from SANY fleets operating in Australian mines and Brazilian construction sites shows that genuine 160102130003A092 washers maintain a leak‑free seal for the full service interval (up to 500 hours between oil changes). The nitrile rubber resists hardening and maintains flexibility even after repeated thermal cycles from -20°C to +120°C.

Aftermarket seal washers often use cheap rubber (e.g., EPDM or natural rubber) that swells in oil or cracks after a few heat cycles. Their zinc plating may be thin (2-3 µm), leading to rust within months. Genuine SANY washers eliminate these issues. Fleet owners report zero drain plug leaks after standardizing on 160102130003A092.

To maximize service life, always use a new washer every time the bolt is removed. Install with the rubber side toward the component. Store spares in a sealed bag away from direct sunlight. Following these practices ensures leak‑free operation and prevents costly fluid loss.
