Toyota camshaft for 4Y petrol/LPG engines.
Manufactured from chilled cast iron with an OHV 8V configuration. Resists forklift camshaft lobe wear for 5FG/6FG/7FG material handling equipment. OEM: 13511-73902 | Cross ref: 13511-73900.
Wholesale available.
The Toyota 4Y 2.2L OHV 8V engine is the cornerstone of material handling equipment, prized for its low-end torque and bulletproof reliability when running on petrol or LPG. Situated deep within the engine block, the Toyota 4Y forklift camshaft (OEM 13511-73902) operates the pushrods and solid lifters that are essential for precise valve timing in warehouse forklift parts. This component guarantees seamless power delivery for demanding industrial fleets, including the globally utilized 5FG forklift camshaft and 6FG/7FG camshaft applications.
Manufactured from premium chilled cast iron, this camshaft undergoes a specialized nitriding process to achieve an HRC 45-55 lobe hardness. In continuous 24/7 warehouse environments, inadequate oil quality or extended maintenance intervals often trigger severe forklift camshaft lobe wear at the flat tappet interface. This friction degradation compromises valve lift and is the primary culprit behind the infamous 4Y engine ticking noise and loss of hydraulic lifting power. Upgrading to our hardened OHV 8V camshaft permanently addresses this vulnerability.
As a primary supplier of wholesale 4Y forklift parts, we ensure exact factory specifications for every Toyota forklift engine rebuild. Our components ensure rapid restoration of your material handling equipment, delivering consistent idle and peak lift dynamics to keep logistics operations running without costly downtime across the globe.

| Make | Machine Model | Year Range | Engine | Application |
|---|---|---|---|---|
| Toyota | Forklift (5FG / 6FG / 7FG / 8FG) | 1986–Present | 4Y (2.2L LPG/Petrol) | Material Handling |
| Toyota | Hilux (YN85 / YN106) | 1988–1997 | 4Y | Pickup Truck |
| Toyota | Hiace (YH50 / YH60 / YH70) | 1982–1989 | 4Y | Commercial Van |

The 4Y utilizes an OHV flat tappet design, which inherently experiences high friction at the cam-to-lifter interface. Using engine oils with inadequate ZDDP (zinc) additives causes metal-on-metal wear during long idle periods in warehouse operations. As the lobes flatten, the resulting valvetrain slack creates a distinct ticking noise. Upgrading to our chilled cast iron camshaft (HRC 45-55) with new solid lifters prevents this degradation.
Yes, OEM 13511-73902 is the direct replacement and superseded part number for the earlier 13511-73900. Both represent the exact same OHV 8V camshaft profile designed for the Toyota 4Y 2.2L engine, ensuring 100% drop-in compatibility across 5FG, 6FG, and 7FG material handling equipment lines.
During installation, the cold valve clearance must be set via the rocker arms to 0.20 mm (0.008 in) for intake valves and 0.30 mm (0.012 in) for exhaust valves using a feeler gauge. The rocker arm shaft support bolts must be tightened to a torque of 24 Nm (18 ft·lb). We strictly recommend installing new solid lifters with your new camshaft to ensure proper break-in of the mating surfaces and avoid immediate damage.
