Material and Design of Fan Bracket Assembly 160102120008A078
The fan bracket assembly 160102120008A078 is cast from ductile iron (GGG40 / EN‑GJS‑400‑15), offering tensile strength of 400 MPa and elongation of 15%. The bracket incorporates a precision‑machined bore for a double‑row ball bearing (6204 size, C3 clearance) that supports the fan shaft. The shaft is made from hardened steel (42CrMo4) and is ground to a tolerance of h6. An integrated flange provides mounting points for the fan pulley and belt tensioner.
The housing is zinc‑nickel plated (8-12 µm) with a black trivalent passivation, providing 500 hours of salt spray resistance (ASTM B117). The bearing is sealed with nitrile rubber and pre‑lubricated for life (no maintenance required). A rubber vibration isolator is mounted between the bracket and the engine block to reduce fan‑induced vibration transmission. The assembly includes four M10 mounting holes on a 120 mm bolt circle.
The bracket is designed to accept a fan with a 250 mm bolt circle (six M8 studs). The fan shaft has a keyway (8 mm x 7 mm) and a threaded end (M16 x 1.5) for securing the fan hub. The overall weight is 4.5 kg, and the maximum allowable fan diameter is 700 mm. The bracket can handle a fan torque of up to 50 Nm and a radial load of 800 N at 3000 rpm.
All 160102120008A078 brackets are 100% CMM‑inspected for bore diameter, flange flatness, and mounting hole positions. A sample from each batch is subjected to a fatigue test (1 million cycles at 120% of maximum load) with no cracking. A laser‑etched batch code on the bracket provides full traceability to the casting lot and machining line.
Function of Fan Bracket 160102120008A078 in Engine Cooling
The fan bracket assembly 160102120008A078 securely mounts the cooling fan to the engine. It positions the fan at the correct distance from the radiator and ensures concentric alignment with the fan shroud. The bracket houses the fan shaft bearing, allowing the fan to rotate smoothly at engine speed (up to 4500 rpm). A misaligned or loose bracket will cause fan blade contact with the shroud, excessive vibration, and premature bearing failure.
The bracket also serves as the mounting point for the belt tensioner (on some applications) and the fan drive pulley. The belt tensioner maintains proper belt tension for the fan drive, alternator, and water pump. A cracked or warped bracket can lead to belt misalignment, causing squealing, belt wear, and loss of cooling capacity.
On SANY D07/D09/D12 engines, this bracket is bolted directly to the front of the cylinder block, replacing the water pump fan mount in some configurations. Always inspect the bracket for cracks when replacing the fan or servicing the cooling system. Use only genuine SANY brackets for guaranteed fit and strength.
Compatible SANY Models & Applications
The fan bracket assembly 160102120008A078 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 bracket fits engines with a 120 mm bolt circle (M10 bolts). The fan shaft has a 25 mm diameter with an 8 mm keyway. Always verify the original bracket dimensions. When ordering, specify 160102120008A078 to receive the correct casting, bearing type, and mounting hole pattern.
For fleet maintenance, stock genuine 160102120008A078 brackets. Aftermarket brackets often use gray iron (brittle) or have insufficient bearing quality, leading to premature failure. Genuine SANY brackets guarantee ductile iron construction, proper bearing preload, and corrosion resistance.

Proper Installation of Fan Bracket Assembly 160102120008A078
Before installing the fan bracket 160102120008A078, clean the engine block mounting surface and the bracket flange. Use new M10 bolts (grade 10.9) and torque them to 50 Nm in a diagonal pattern. Do not reuse old bolts. Ensure the bracket is seated flush against the block before tightening. If a rubber isolator is used, install it between the bracket and the block.
Slide the fan onto the shaft, aligning the keyway. Install the key and tighten the fan hub nut to 80 Nm. Rotate the fan by hand to check for binding – any roughness indicates bearing damage. Install the fan belt and tension it to 5‑7 mm deflection per 100 mm span. After running the engine for 30 minutes, re‑tighten the mounting bolts to 50 Nm.
If the bracket is being replaced due to bearing failure, inspect the fan for imbalance and replace if damaged. Always use a new fan key and nut. Store new brackets in a dry environment. Use only genuine SANY brackets – aftermarket parts may have incorrect bearing preload or poor casting quality.
Symptoms of a Damaged Fan Bracket Assembly
A failed 160102120008A078 fan bracket typically shows excessive fan wobble, grinding noises from the bearing, or belt misalignment. You may see rust streaks from the bearing (if the seal failed). A cracked bracket will cause the fan to tilt, resulting in blade‑to‑shroud contact and severe vibration. The bracket may also develop cracks around the mounting holes due to over‑tightening or fatigue.
If the bearing fails, the fan may seize, snapping the drive belt and causing loss of cooling, alternator, and water pump. A seized bearing also generates heat that can melt nearby components. If the bracket is warped (non‑flat), the fan will not align with the radiator, reducing cooling efficiency.
During maintenance, inspect the bracket for cracks using dye penetrant. Check the bearing for play (axial and radial) – any detectable movement indicates replacement. Replace the bracket every 10,000 hours as preventive maintenance. Use only genuine SANY brackets for replacement.
