OEM 61000140 – The genuine SANY parts Hexagon Bolt is a high‑strength fastener specifically engineered for critical timing gear and camshaft drive applications in SANY heavy‑duty diesel engines. With reference 61000140, this bolt is used to secure the camshaft timing gear (61000140 is also the gear assembly number, and this bolt is a component of that assembly).
Manufactured from heat‑treated alloy steel to property class 10.9, the 61000140 hexagon bolt delivers a minimum tensile strength of 1,040 MPa and exceptional fatigue resistance. It features precision‑rolled threads and a zinc‑flaked coating for maximum corrosion protection. This bolt is a direct OEM replacement for Actlon tippers, SY mining dump trucks, concrete mixers, and all SANY equipment powered by D09, D12, D13, WP12, and WP13 engines. Trust the authentic 61000140 component to maintain timing accuracy and prevent gear train failures.

61000140 Hexagon Bolt – Precision Fastener for SANY Camshaft Timing Gear Assembly
The hexagon bolt with OEM number 61000140 is a high‑strength fastener used in the SANY Camshaft Timing Gear Assembly (also referenced as 61000140).
This bolt securely attaches the timing gear to the camshaft, ensuring precise angular alignment and reliable torque transmission.
Correct clamping force from this bolt is essential for maintaining camshaft to crankshaft timing accuracy, which directly affects engine performance.
The SANY Camshaft Timing Gear Assembly comprises the camshaft gear and six high‑strength hexagon bolts, each with OEM number 61000140.
This bolt is manufactured from chromium‑molybdenum alloy steel (SAE 4140 or equivalent) and heat‑treated to property class 10.9 per ISO 898-1.
The minimum tensile strength is 1,040 MPa, with a yield strength of 940 MPa and a hardness range of 32–39 HRC.
Threads are precision‑rolled rather than cut, improving fatigue resistance by eliminating stress risers and work‑hardening the thread root.
The bolt head features a hexagon drive (size 13 mm or 17 mm across flats, depending on variant) and is marked with the property class “10.9”.
A zinc flake coating (Geomet 321 or equivalent) provides 720 hours of salt spray resistance, preventing galvanic corrosion in harsh environments.
Every genuine 61000140 bolt is 100% inspected for dimensional accuracy, hardness, and surface finish using automated gauging systems.
Using a sub‑standard bolt in the camshaft timing gear assembly can lead to clamp load loss, gear slippage, and catastrophic valve‑to‑piston contact.
Grade 10.9 Strength
Minimum tensile strength 1,040 MPa – 30% stronger than Grade 8.8 bolts, ideal for timing gear applications.
Rolled Threads
Cold‑rolled thread roots increase fatigue life by 200% compared to cut threads, eliminating stress risers.
Corrosion Protected
Zinc flake coating (Geomet 321 equivalent) provides 720h salt spray resistance, Cr(VI)-free.
Traceable Quality
100% dimensional and hardness inspection per batch, labeled with OEM 61000140 and heat lot number.

Why Genuine SANY 61000140 Hexagon Bolt Is Superior to Aftermarket Fasteners
Aftermarket hexagon bolts are often manufactured from lower‑quality carbon steel without proper heat treatment, resulting in lower strength (often Grade 8.8 or unmarked).
Using a sub‑standard bolt in the camshaft timing gear assembly can cause thread stripping, clamp load loss, and eventual gear slippage.
The genuine 61000140 bolt is manufactured from premium chromium‑molybdenum alloy steel and heat‑treated to achieve consistent mechanical properties.
Aftermarket fasteners often have cut threads with sharp roots, which act as stress concentrators and reduce fatigue life.
Genuine SANY bolts feature rolled threads that work‑harden the thread root and eliminate stress risers, providing up to 200% longer fatigue life.
Poor corrosion protection is another common failure. Basic zinc plating rusts after 72 hours of salt exposure.
The genuine 61000140 bolt is coated with zinc flake technology, providing 720 hours of salt spray resistance – ten times better than standard hardware.
For critical timing gear applications, using the correct genuine fastener is essential for engine reliability and safety.
- Certified 10.9 material – 1,040 MPa tensile strength, verified by batch testing.
- Rolled threads improve fatigue resistance by 200% vs. cut threads.

Compatibility & Installation Guidelines
The 61000140 hexagon bolt is compatible with SANY D09, D12, D13, WP12G460E50, and WP13G500E30 diesel engines.
It is used in Actlon 6×4/8×4 tippers, SY331, SY412, SY425 mining dump trucks, SYM3310 series, concrete mixer trucks, wheel loaders, motor graders, and STC truck cranes.
Application examples: Camshaft timing gear attachment, idler gear assembly fastening, and general engine timing system securing.
Before installation, clean the threaded holes and ensure they are free of oil and debris. Lubricate threads with light engine oil.
Tighten using a calibrated torque wrench following the prescribed sequence and torque specification (e.g., 25 Nm ± 3 Nm for dry assembly).
Do not reuse torque‑to‑yield bolts. Always replace with new genuine SANY fasteners after removal.
Never mix bolts of different grades or manufacturers in the same assembly. Use only genuine 61000140 fasteners.
Store bolts in a dry environment and keep them in original packaging until use to preserve the corrosion protection coating.
