The connecting rod used in engines manufactured by Deutz AG for the 912, 1011, 1012, and 1013 series is a forged alloy steel component designed for high fatigue resistance. It is installed between the piston pin at the small end and the crankshaft journal at the big end, converting reciprocating motion into rotational torque. Each cylinder uses one connecting rod, so a 4 cylinder engine contains four rods and a 6 cylinder version contains six rods. Typical center to center length ranges from 145 mm in 912 series to approximately 165 mm in 1013 series, depending on stroke configuration. The big end housing bore commonly ranges between 58 mm and 72 mm, matched to crankpin diameter and bearing shell thickness.

In the 1011, 1012, and 1013 engines, the connecting rod is secured to the crankshaft using two high tensile bolts tightened to torque plus angle specification to ensure correct preload. The big end uses bi metal or tri metal bearing shells with oil clearance typically between 0.03 mm and 0.08 mm for hydrodynamic lubrication stability. The small end incorporates a bronze bushing with an internal diameter tolerance within ±0.01 mm to control piston pin fit. Rod weight is precision matched within a few grams per engine set to minimize vibration. Proper alignment and side clearance, usually 0.15 mm to 0.40 mm, directly influence engine durability, oil pressure stability, and long term crankshaft life.You can order and buy deutz engine 912 1011 1012 and 1013 connecting rod from Iran by contacting us through whatsaap and email.

DEUTZ engine connecting rod metallurgy, strength and material

The original equipment connecting rod in Deutz engines is manufactured from a forged low alloy steel such as 42CrMo4 or equivalent SAE 4140 grade with a tensile strength typically above 900 MPa after heat treatment. Microstructure refinement through quenching and tempering produces a balanced hardness of about 280-320 HB on the shank and 200-240 HB in bearing zones to resist surface fatigue and plastic deformation. Shot peening the rod beam induces compressive residual stress of roughly 300-400 MPa on critical fatigue surfaces to improve endurance limit by 15-25 %. OE rods use precision machined bearing seats with tribologically optimized coatings to maintain sufficient oil film thickness under journal speeds reaching 20 m/s. Wear testing under boundary lubrication shows material loss rates below 0.005 mm³/Nm, supporting long service intervals of 500 + hours in heavy duty applications.

Impact and dynamic loading performance of Deutz OE connecting rods is engineered to withstand peak combustion pressures up to 180 bar with minimal plastic strain. The forged cross section and optimized I-beam geometry deliver a high specific energy absorption, with fracture toughness K_IC values above 70 MPa√m, reducing risk of brittle failure under detonation or reverse torque events. Fatigue life for rotating bending loads is validated beyond 1 × 10⁷ cycles at 80 % of yield stress, ensuring durability across varied duty cycles. Precision dimensional control keeps small end to big end alignment within ±0.05 mm to minimize lateral forces and bearing edge loading, preserving crankshaft dynamics and reducing wear progression.
