The crankshaft of the VOLVO L90 and L120 loader OE stock is a critical component that converts the pistons’ reciprocating motion into rotational motion of the engine shaft. It is manufactured from alloy steel with controlled heat treatment and a surface hardness of 50–55 HRC, with main journal diameters ranging from 90 to 120 millimeters. The main shaft is mounted on the engine block’s main bearings and can withstand radial torques up to 12,000 N·m and axial loads of 3,500 N, ensuring reliable power transmission to the gearbox and hydraulic pump. Precisely designed elliptical journals and dynamic balancing within ±2 g·cm reduce vibration and extend engine life beyond 15,000 operating hours.

The crankshaft is installed on five main bearings with diameters of 80–100 millimeters and secured by four M16 class 10.9 bolts to the engine block. Its function converts piston strokes of 110–130 millimeters into rotational speeds of 2,200–2,400 RPM. Oil lubrication channels operate under pressures up to 6 bar, reducing surface wear on bearings. Fatigue strength exceeds 10^7 cycles, and shaft alignment accuracy is below 0.05 millimeter, ensuring stable performance and long service life even under full-load conditions.You can order and buy Volvo loader L90 and L120 crankshaft from Iran by contacting us through whatsaap and email.

Comparison of quality, price and durability of stock volvo loader crankshaft

In terms of quality, the OEM stock crankshaft for Volvo loaders outperforms Chinese alternatives by using precision alloy steel with a surface hardness of 50–55 HRC and uniform surface treatments, whereas Chinese units typically use general steel with hardness of 40–48 HRC. Volvo crankshafts maintain machining tolerances below ±0.02 millimeter, while Chinese units can reach ±0.05 millimeter, increasing bearing wear. Fatigue life of the genuine crankshaft exceeds 10^7 cycles with vibration under 0.7 millimeters, while Chinese replacements may show cracks or fatigue signs after 5,000–8,000 operating hours.

Regarding price, the Volvo OEM crankshaft is generally 3–4 times more expensive than Chinese units due to quality testing, shaft alignment assurance, and aftermarket support. Real-world durability under full load exceeds 15,000 hours for the genuine part, while Chinese units may degrade after 6,000–9,000 hours. Differences in surface finish, dynamic balancing within ±2 g·cm, and pressurized oil channels at 6 bar ensure stable operational performance for the Volvo crankshaft, which is rarely matched by Chinese alternatives.
