The Shacman X5000 Intermediate Rocker Arm Assembly is an OEM steering rocker system that includes the middle rocker arm, needle roller bearings, and O‑shaped ring seals. This assembly transmits steering force between the drop arm and the tie rod.
Engineered by Shacman, this intermediate rocker arm assembly ensures smooth, precise steering for X5000 trucks. The Shacman X5000 Intermediate Rocker Arm Assembly restores original steering response and durability.
The Needle Roller Bearing (Part 119000410228) is a high-capacity radial bearing designed for the rocker arm pivot. It has an inner diameter of 35mm, outer diameter of 47mm, and width of 30mm. The bearing contains 26 steel needles (2×2.5mm) held in a drawn cup. Load rating: dynamic 38 kN, static 55 kN. Operating speed up to 3,000 rpm. The bearing is lubricated with high-temperature grease and sealed with two integral lip seals. It provides low friction rotation of the rocker arm shaft. Two bearings are used per assembly. Replace if any needle shows pitting or if rotation is notchy. Supplied with a new snap ring.

The O-Shaped Ring Seal (Part 188000340023) is a viton (FKM) O‑ring measuring 40mm ID x 3.5mm cross section. It seals the interface between the rocker arm housing and the pivot shaft, preventing grease leakage and dirt ingress. Working temperature range: -30°C to +200°C. Resistant to mineral oil, diesel, and hydraulic fluid. Two seals are supplied per assembly; they are installed on both sides of the rocker arm. The O‑ring has a hardness of 75 Shore A and a tensile strength of 12 MPa. Replace every time the rocker arm is disassembled. Never reuse old O‑rings.

The Middle Rocker Arm (Part DZ9118470601) is the central steering transfer component. It is a ductile iron casting (GJS-700-2) with a total length of 280mm and a weight of 3.8 kg. The arm features a splined bore (35mm, 36 teeth) for the pivot shaft and two tapered ball joint sockets (M26x1.5 threads). The arm is heat treated to 35 HRC on the bearing surfaces and phosphated for corrosion protection. It incorporates a grease groove and a Zerk fitting for lubrication.

🚛 Complete Kit – Ready to Install – Includes rocker arm, two needle bearings, and two O‑rings. One order provides all parts needed to rebuild the intermediate rocker. Backed by 12‑month unlimited‑mileage warranty. Fleet discounts available.
Needle roller bearing: 35x47x30 mm, dynamic load rating 38 kN, static 55 kN, limiting speed 3,000 rpm. O‑ring: 40mm ID x 3.5mm, FKM 75 Shore A. Rocker arm: GJS-700-2, length 280mm, spline 35mm x 36 teeth, ball joint taper 1:10. Assembly weight: 4.2 kg. The Shacman X5000 Intermediate Rocker Arm Assembly is tested to 2 million oscillation cycles at 25 kN alternating load. No bearing wear or rocker arm deformation observed.
Grease volume: 12g per bearing. Recommended grease: NLGI #2 lithium complex with EP additives. Operating temperature: -40°C to +120°C (bearing), -30°C to +200°C (O‑ring).
Temp Range
Bearings: -40°C to +120°C. O‑rings: -30°C to +200°C.
Applications
Shacman X5000, X3000, F3000 steering linkage. Replaces original intermediate rocker arm assembly.
Certifications
IATF 16949, ISO 9001. Material certificates EN 10204 3.1 available.
1. Press new needle bearings into the rocker arm housing using a suitable mandrel. 2. Install O‑rings into the grooves on both sides of the rocker arm. 3. Mount rocker arm onto pivot shaft, torque pivot bolt to 200 Nm. 4. Connect tie rod ends to the rocker arm ball joints, torque castle nuts to 150 Nm and install split pins. 5. Grease the rocker arm through the Zerk fitting until grease purges from the seals. Replace O‑rings each time the rocker arm is removed. Never reuse bearings after removal – they are press‑fit and should be replaced.
Needle bearing: drawn cup from 100Cr6 steel, needles from 100Cr6, heat treated HRC 60-64. O‑ring: FKM (Viton) moulded, post‑cured. Rocker arm: sand cast ductile iron, heat treated, CNC machined. 100% non‑destructive testing on castings. Bearings are 100% noise tested. Sample arms undergo 500,000 cycle fatigue test. Each assembly is packed with desiccant and labeled with serial number.
A worn intermediate rocker arm causes excessive free‑play in the steering linkage, leading to tire wear and driver fatigue. Rebuilding with genuine Shacman X5000 Intermediate Rocker Arm Assembly restores steering precision and reduces toe‑in corrections. The needle roller bearings extend pivot life by 300% compared to plain bushings. Lower total cost of ownership.

Excessive steering free‑play (>15mm at steering wheel rim), clunking from the middle of the front axle, uneven tire wear, visible grease leakage around the rocker arm, seized or notchy rotation. Replace with Shacman X5000 Intermediate Rocker Arm Assembly immediately. Replace bearings and O‑rings as a set.
Inspect every 100,000 km. Check for radial play at the rocker arm pivot. Re‑grease every 50,000 km.
Aftermarket rocker arms are often cast from inferior grey iron (GG25) that cracks under load. Bearings are generic stamped cages without proper heat treatment. O‑rings are NBR that harden at 100°C. Our genuine Shacman X5000 Intermediate Rocker Arm Assembly uses ductile iron GJS-700, precision needle bearings, and viton O‑rings. Choose original for safety and longevity.
Final recommendation: Always replace the complete intermediate rocker arm assembly including all bearings and O‑rings. The Shacman X5000 Intermediate Rocker Arm Assembly provides a complete, matched set for a reliable steering linkage. Trust genuine Shacman for original quality.
