The 160102130003A008 Flywheel Housing Plate is a precision-machined plate that mounts between the engine block and the flywheel housing assembly. It provides the accurate interface required to align the engine crankshaft with the transmission input shaft, ensuring optimal clutch engagement and vibration-free operation. This plate is a documented component within the SANY Flywheel Housing Group.

The flywheel housing plate serves as the structural interface between the engine and transmission systems, providing accurate positioning of the starter motor, flywheel housing, and transmission bell housing. The 160102130003A008 plate ensures perfect concentricity between the crankshaft centerline and the transmission input shaft, preventing premature bearing wear, clutch damage, and driveline vibration.

The SANY D12 engine, jointly developed with DEUTZ, has a displacement of 12.12 liters and six cylinders. It delivers 360 kW (490 hp) at 1,900–2,100 rpm and a maximum torque of 2,150 Nm, meeting Euro VI emission regulations through its 1,800 bar common-rail injection system. The D09 engine is a 9‑liter six-cylinder unit producing 280–380 hp with 1,500 Nm of torque.

In the SANY Flywheel Housing Group catalog, the 160102130003A008 Flywheel Housing Plate is used with a quantity of one unit per assembly. The plate works in coordination with Hexagon Head Bolts (Part No. 61000156), Inner Hexagon Screws (Part No. 60272460), Inner Hexagon Socket Head Cap Screws (Part No. 60326075), Straight pins (Part No. 60272600), and the Crankshaft Sensor (Part No. 60033243).

The plate is manufactured from high-strength cast iron or fabricated steel, with precision-machined locating dowel holes and threaded mounting bosses. The mating surfaces are finished to extremely tight flatness and surface roughness specifications, ensuring leak-free sealing against the engine block and flywheel housing.

Precision alignment of the flywheel housing plate is critical for maintaining crankshaft-to-transmission geometry. Any deviation in plate flatness or dowel pin positioning can cause input shaft misalignment, leading to clutch cover distortion, pilot bearing failure, and transmission gear noise.

The 160102130003A008 Flywheel Housing Plate is designed for a long service life under extreme torsional loads. However, plates can become damaged during transmission removal due to mishandling, corrosion from external exposure, or warpage from improper bolt torque. When these conditions occur, the plate must be replaced to restore proper powertrain alignment.

The flywheel housing plate is one of the most critical components for driveline reliability. Any error in its thickness, flatness, or dowel pin location will directly affect the alignment between the engine and transmission. Misalignment of even 0.2 mm can cause the clutch disc to run at an angle, leading to uneven wear, clutch chatter, and eventual failure.

For the D12 engine, the flywheel housing plate ensures that the crankshaft flywheel pilot bearing aligns perfectly with the transmission input shaft. A misaligned input shaft will quickly destroy the pilot bearing, resulting in a rattling noise, clutch difficulty, and eventual input shaft seal leakage.

The D12 engine’s fuel consumption is as low as 187 g/kWh, which is significantly lower than competitor engines. To maintain this efficiency, the engine and transmission must operate as a perfectly aligned unit. A misaligned flywheel housing plate adds drag, wasting fuel and increasing wear. That efficiency relies on the precise alignment provided by a genuine SANY flywheel housing plate.

The D12 can start in as little as two seconds at an altitude of 3,000 meters with temperatures as low as -20 °C. The crankshaft sensor, which is mounted to the flywheel housing, requires a precise air gap to generate a consistent signal. An incorrectly positioned plate changes the sensor gap, causing starting issues, erratic engine operation, and fault code generation.

When the flywheel housing plate is warped or damaged, the flywheel housing itself can crack under bolt tension. Cracks in the housing allow the starter motor to misalign, leading to starter gear grinding, ring gear damage, and engine block damage. Replacing a damaged flywheel housing plate is always preferable to repairing a cracked housing or replacing the entire engine block.

During any clutch replacement or transmission removal, the flywheel housing plate should be thoroughly inspected. Check the plate for flatness using a straight edge and feeler gauge. Inspect the dowel pin holes for wear, the mounting surfaces for corrosion, and the crankshaft sensor mounting boss for damage. If any of these conditions are present, replace the plate.

The 160102130003A008 Flywheel Housing Plate is used in SANY D12 and D09 engine installations across multiple heavy equipment platforms. Verified compatible equipment includes SANY Kingway 435 heavy trucks, SYZ series dump trucks for mining and construction hauling, concrete mixer trucks and truck-mounted pumps from SANY’s concrete machinery division, and SANY SKT105 mining dump trucks.

Beyond those, the plate is also used in SANY SY and SYH series excavators, wheel loaders, and STC series truck cranes equipped with D09 or D12 powerplants. In all these applications, the flywheel housing plate is the critical interface that allows the engine to be mounted to the transmission or clutch housing.

When performing engine removal or transmission service, the flywheel housing plate should be cleaned and inspected. Replace any fasteners that show thread damage or corrosion. Always use a new gasket or sealing compound between the plate and the engine block as specified by SANY. Torque all bolts to the specification listed in the service manual, using a crossing pattern to avoid distorting the plate.

Before installing the new 160102130003A008 Flywheel Housing Plate, thoroughly clean the mating surface on the engine block. Remove all old gasket material, corrosion, and debris. Inspect the block surface for nicks or scratches that could prevent the plate from seating flush. Use a straight edge to verify block flatness if there is any doubt.

Position the new plate over the engine block dowel pins. The dowel pins ensure correct positioning of the plate relative to the crankshaft centerline. If the dowel pins are damaged or missing, replace them before installing the plate. Do not attempt to install the plate without dowel pins; alignment will be lost.

Apply a thin, even bead of SANY-approved sealant or install a new gasket between the plate and the block as specified in the service manual. Hand‑start the mounting bolts and tighten them in a crossing sequence to final torque. Use a calibrated torque wrench and follow the torque specifications (typically 180‑220 Nm, depending on the bolt size).

After the plate is installed, verify that the crankshaft sensor mounting boss is clean and that the sensor mounting hole is free of debris. Install the crankshaft sensor (Part No. 60033243) with the recommended air gap. Failure to set the correct air gap can cause sensor signal errors, misfiring, or starting problems.

During routine maintenance, inspect the plate for signs of oil leaks around the mounting flange, for loose bolts, or for cracks radiating from bolt holes. If any of these conditions are observed, replace the plate and the associated fasteners. A cracked plate cannot be repaired; replacement is the only safe option.

Counterfeit or generic flywheel housing plates are a significant risk in the aftermarket. Generic plates may be made from lower‑grade cast iron, may have incorrect dowel pin locations, or may be machined to imprecise thickness tolerances. Using a non‑genuine plate can misalign the engine and transmission by a fraction of a degree, causing chronic vibration, clutch wear, and increased fuel consumption.

Generic plates also frequently lack the correct corrosion protection, leading to rust on the mounting faces that destroys the seal between the plate and the block. Rust also attacks the thread bores, causing bolts to seize, cross‑thread, or lose their torque retention.
