The Ruich Value 1HZ camshaft (OEM: 13501-17010) is a chilled cast iron component with SOHC 12V configuration.
It resolves cam lobe wear and fits Land Cruiser HZJ75, HZJ79, HZJ105 & Coaster.
In stock for global export.
Looking for a reliable 1HZ camshaft replacement? The Toyota 1HZ engine is legendary in off-road and commercial applications, but high-mileage blocks frequently suffer from valvetrain degradation. When supplying Land Cruiser 70 series camshaft components to global fleet managers, maintaining original QDR (Quality, Durability, and Reliability) is our top priority. This heavy duty diesel camshaft is engineered to restore factory valve timing and combustion efficiency for demanding work environments.
Prolonged operation in harsh conditions often leads to camshaft lobe wear symptoms, which operators first notice as excessive valve train clatter or a sudden drop in low-end torque. Our Land Cruiser HZJ79 camshaft is manufactured from premium chilled cast iron, ensuring the induction-hardened lobes resist surface fatigue even under poor lubrication conditions. The precision-ground journals (machined to an Ra 0.2 micro-finish) provide a perfect hydrodynamic oil film to prevent metal-to-metal scoring during cold starts.

This Toyota Coaster 1HZ camshaft is fully compatible with both early and late model 4.2L indirect injection blocks across the following applications:
| Make | Machine Model | Year Range | Engine | Application |
|---|---|---|---|---|
| Toyota | Land Cruiser (HZJ75/78/79) | 1990–2007 | 1HZ (4.2L) | Off-Road 4×4 / Mining |
| Toyota | Land Cruiser (HZJ80/105) | 1990–2007 | 1HZ (4.2L) | SUV / Fleet |
| Toyota | Coaster Bus (HZB40/50) | 1993–2004 | 1HZ (4.2L) | Commercial Transport |
Yes, this camshaft is also compatible with the 1HD-T turbocharged engine (OEM 13501-17020), as both engines share the exact same SOHC 12V valvetrain physical design. While the factory 1HZ cam (13501-17010) has approximately 0.65mm more intake lift than the factory 1HD-T cam, engine rebuilders frequently interchange them as a direct bolt-in replacement. Always verify your valve clearances and ensure your shim adjustments are correct before final installation.
A pronounced ticking noise and diesel engine rough idle are classic signs of valvetrain wear. In the 1HZ, this is typically caused by camshaft lobe wipe (where the peak of the lobe wears flat) or excessive valve clearance due to shim wear. The intake lobe height should measure 55.09-55.11 mm; anything below the 54.59 mm limit requires immediate replacement to restore proper valve overlap and idle stability.
Proper installation is critical to prevent journal binding. According to factory specifications, the No.1 bearing cap must be torqued to 25 Nm (18 ft·lbf), while bearing caps No.2 through No.7 require 18 Nm (13 ft·lbf). Always tighten the 14 bearing cap bolts uniformly in several passes from the center outward to prevent shaft distortion and ensure the hydrodynamic oil film is maintained.
