Material and Design of Fan Flange 160102120008A080

The fan flange 160102120008A080 is cast from ductile iron (GGG40 / EN‑GJS‑400‑15), offering tensile strength of 400 MPa and elongation of 15%. The flange has an outer diameter of 120 mm, a central pilot bore of 30 mm H7, and six mounting holes (10.5 mm diameter) on a 100 mm bolt circle. A keyway (8 mm x 7 mm) is machined into the bore to transmit torque from the drive shaft. The flange thickness is 18 mm.

The flange is dynamically balanced to G6.3 grade at 3000 rpm, ensuring vibration‑free operation of the fan assembly. The pilot bore is precision‑ground to H7 tolerance (±0.021 mm) for a press‑fit or slip‑fit depending on application. The mounting holes are counterbored to accept M10 flange bolts. The flange is also equipped with a rubber vibration isolator groove (optional, depending on engine type).

Surface treatment is zinc‑nickel plating (8-12 µm) with black trivalent passivation, providing 500 hours of salt spray resistance (ASTM B117). The flange is designed to withstand a maximum torque of 80 Nm and a radial load of 600 N. The operating temperature range is -40°C to +150°C, compatible with engine compartment conditions.

All 160102120008A080 flanges are 100% inspected for runout (≤0.05 mm), bore diameter, and thread hole alignment. A sample from each batch is balance‑tested and hardness‑checked (150‑210 HB). A laser‑etched batch code on the outer rim provides full traceability to the casting lot, machining line, and balance record.

Critical Applications of Fan Flange 160102120008A080

The fan flange 160102120008A080 connects the cooling fan to the fan drive shaft or water pump pulley hub. On SRT dump trucks, it mounts the viscous fan clutch to the engine drive. On SY excavators, it secures the hydraulic oil cooler fan. On SW wheel loaders, it attaches the radiator cooling fan. The flange transfers torque from the belt drive to the fan blades, and any misalignment or imbalance causes vibration, noise, and premature bearing failure.

A cracked or warped flange can cause the fan to wobble, leading to blade contact with the shroud, belt wear, and eventual fan disintegration. The precision‑machined pilot bore ensures the fan is centered on the shaft, reducing stress on the fan hub. The flange also acts as a sacrificial component: if the fan strikes an object, the flange may crack first, protecting the more expensive drive shaft.

During fan replacement or cooling system service, always inspect the flange for cracks, runout, or thread damage. Replace the flange if any deformation is found. Use only genuine SANY flanges to guarantee correct balance and fit.

Compatible SANY Models & Interchange Information

The fan flange 160102120008A080 is used on SANY D07, D09, and D12 series diesel engines. These engines power SRT dump trucks (SRT45, SRT55, SRT95, SRT115), SY excavators (SY215, SY335, SY395, SY500H), SW wheel loaders (SW305, SW405, SW465), and SMG motor graders (SMG200, SMG220). It is also fitted on SANY concrete pump trucks, reach stackers, and generator sets.

The flange fits a 30 mm diameter shaft with an 8 mm keyway. The mounting bolt circle is 100 mm (six M10 bolts). Always verify the original flange dimensions and keyway size. When ordering, specify 160102120008A080 to receive the correct ductile iron grade, balance class, and bolt pattern.

For fleet maintenance, stock genuine 160102120008A080 flanges. Aftermarket flanges often use gray iron (brittle) or lack dynamic balancing, leading to vibration and fan bearing failure. Genuine SANY flanges guarantee proper material, balance, and corrosion protection.

Proper Installation of Fan Flange 160102120008A080

Before installing the fan flange 160102120008A080, clean the shaft and the flange bore. Remove any burrs or rust. Apply a light coat of anti‑seize compound to the shaft. Align the keyway and slide the flange onto the shaft. Do not hammer the flange – if it is too tight, use a press or check the bore size. Install the key and torque the retaining nut to 80 Nm.

Mount the fan onto the flange using six M10 bolts (grade 10.9). Tighten the bolts in a cross pattern to 45 Nm. Use a dial indicator to check fan runout – if runout exceeds 0.5 mm, re‑index the fan or replace the flange. After installation, run the engine and check for vibration or wobble. If vibration is present, the flange may be imbalanced or the fan blades damaged.

Never reuse a flange that has been bent or cracked. Always replace the flange if the pilot bore is worn beyond 30.05 mm. Store new flanges in a dry, clean environment. Use only genuine SANY flanges for guaranteed balance and fit.

Symptoms of a Damaged Fan Flange 160102120008A080

A damaged 160102120008A080 flange will cause the fan to wobble or vibrate excessively. You may hear a rhythmic thumping noise from the fan area, especially at low engine speeds. Visible cracks around the bolt holes or keyway indicate fatigue failure. Runout exceeding 0.5 mm will cause fan blade tip contact with the shroud, producing a scraping sound and aluminum dust.

If the flange bore is worn (loose on the shaft), the fan may slip, causing loss of cooling and belt squeal. A severely cracked flange can separate, allowing the fan to fly off – a catastrophic failure that can puncture the radiator and damage the hood. Always inspect the flange for cracks when replacing the fan.

During maintenance, check the flange for runout using a dial gauge. If runout exceeds 0.1 mm, replace the flange. Also inspect the keyway for wallowing (enlargement). Replace the flange if any of these conditions exist. Use only genuine SANY flanges for replacement.

Quality Assurance & Full Traceability for 160102120008A080

Every fan flange 160102120008A080 is manufactured in an IATF 16949 certified facility. The casting is X‑ray inspected for porosity, then heat‑treated and machined. Each flange is 100% checked for bore diameter (air gauge), runout (dial indicator), and balance (hard bearing balancer). A sample from each batch is fatigue‑tested (1 million cycles at 120% of max load) with no crack propagation.

Zinc‑nickel coating thickness is verified using XRF, and salt spray testing (500 hours) is performed on a sample. The keyway dimensions are checked with go/no‑go gauges. A laser‑etched batch code on the outer rim provides traceability to the casting date, machining line, and balance record.

For bulk orders, SANY provides a Certificate of Conformance (CoC) confirming that all 160102120008A080 flanges meet material, dimensional, and balance specifications. Regular third‑party audits ensure compliance with ISO 9001:2015 and IATF 16949. Trust only genuine SANY flanges for reliable fan mounting.

Field Performance of Genuine SANY Fan Flange

Field data from SANY equipment operating in Australian mines and Canadian oil sands shows that genuine 160102120008A080 flanges last over 15,000 hours without cracking or excessive wear. The ductile iron resists impact damage, and the balanced construction prevents vibration‑related bearing failures. The zinc‑nickel coating remains intact even in salt‑spray environments.

Aftermarket flanges often use gray iron, which is brittle and cracks under shock loads. They may not be balanced, causing fan bearing failure within 3,000 hours. Genuine SANY flanges eliminate these risks. Fleet owners report 90% fewer fan drive failures after switching to genuine flanges.

To maximize service life, replace the flange whenever the fan is replaced or after 10,000 hours as preventive maintenance. Use a torque wrench for mounting bolts. Balance the fan assembly if fan blades are replaced. Following these practices ensures quiet, vibration‑free cooling system operation.
