Wheel Hub Bolt 1-42333335-0 1-42333336-0 1423333350 1423333360 for ISUZU CVR FTR 10PE1 6RB1 6HK1 Diesel Truck — Verified Direct-Fit Replacement
The Hub Bolt with OEM numbers 1-42333335-0 (cross-ref 1423333350) and 1-42333336-0 (cross-ref 1423333360) is a verified direct-fit replacement for ISUZU CVR and FTR series commercial trucks equipped with 10PE1, 6RB1, and 6HK1 diesel engines. This hub bolt is a critical fastening component between the wheel and hub assembly, responsible for securely clamping the wheel to the hub flange and withstanding all radial and axial loads during vehicle operation.
- OEM Standard Dimensions: Manufactured to ISUZU OEM standard size for direct replacement without modification.
- Material Grade: High-strength alloy steel construction with T-shaped head design, suitable for high-torque applications, strength grade 8.8 or above.
- Heat Treatment: Controlled heat-treating process produces a hard, wear-resistant surface while maintaining a ductile core for long-term alternating load resistance.
- Thread Precision: M22 thread size, precision-rolled for tight fit with wheel nuts and reliable preload retention.
- OEM Cross-Reference Verified: Replaces 1-42333335-0 / 1423333350 and 1-42333336-0 / 1423333360.
- Bolt Elongation: When bolt diameter reduces from standard 22 mm to below 21.5 mm, the bolt has undergone plastic deformation and must be replaced immediately.
- Cracks or Fracture: Under prolonged vibration and alternating loads, bolts may develop cracks and eventually fracture.
- Thread Damage or Seizure: Nuts that do not turn smoothly indicate defective threads; replace both bolt and nut as a set.
- Noticeable Rust: Significant rust on the bolt surface weakens its load-bearing capacity.
- Frequent Wheel Nut Loosening: Nuts that repeatedly loosen after re-tightening signal insufficient preload or thread wear.

Installation Guidelines (Reference ISUZU Workshop Manual):
- Clean hub fitting surface, wheel nut seating surfaces, and bolt threads to remove rust, dust, and oil.
- Inspect hub bolt holes for cracks or deformation.
- Insert new bolt into hub flange hole, ensuring proper seating.
- Tighten to ISUZU workshop manual specified torque (reference range: wheel nuts 108–135 N·m; consult vehicle-specific manual for exact value).
- Tighten in star pattern in multiple stages for even load distribution.
Maintenance Schedule:
- Inspect hub bolt condition at every tire change or brake service.
- Re-check wheel nut torque after 50–100 km of driving to account for initial settling.
- Replace immediately if cracks, elongation, or thread damage are detected.
- Neutral carton/wooden case packaging with individual anti-rust wrapping.
- Custom branded packaging available (authorization letter required).
- MOQ: Please contact for confirmation.
- Suitable for: ISUZU truck repair shops, parts wholesalers, fleet maintenance departments.
