The Toyota 1Z forklift camshaft (OEM: 13501-78200) is a chilled cast iron camshaft with an OHV 8V configuration.
It resolves critical lobe wear issues and fits 5FD and 6FD series material handling equipment.
In stock for global export.
Maintaining peak performance in heavy-duty warehouse operations requires robust powertrain components. The 3.0L Toyota 1Z diesel engine is legendary for its reliability, but thousands of hours of continuous lifting operations eventually take a toll on the valvetrain. Our replacement Toyota 5FD forklift camshaft is engineered to restore factory valve timing and fuel efficiency for aging equipment, ensuring fleet managers avoid costly downtime.
A common issue in aging fleets is severe 1Z camshaft lobe wear, caused by degraded oil or infrequent maintenance. Because the 1Z is an Overhead Valve (OHV) block-mounted design, worn lifters grinding against the lobes will quickly lead to loss of engine power and excessive valvetrain noise. Manufactured from high-grade chilled cast iron, our camshafts feature induction-hardened lobes (HRC 50-55) that withstand poor lubrication environments, providing a permanent fix for material handling fleets worldwide.

This camshaft is a direct bolt-in replacement for the 3.0L 1Z OHV diesel engine, servicing a wide range of 6FD forklift engine parts and 5FD series equipment:
| Make | Machine Model | Year Range | Engine | Application |
|---|---|---|---|---|
| Toyota | 5FD Series (5FD10, 5FD15, 5FD25) | 1986–1994 | 1Z (3.0L) | Warehouse Forklift |
| Toyota | 6FD Series (6FD20, 6FD25, 6FD30) | 1994–1998 | 1Z (3.0L) | Warehouse Forklift |
| Toyota | 5FDC Series Tow Tractors | 1986–1994 | 1Z (3.0L) | Industrial Towing |
No, while the 1Z, 2Z, and 11Z share similar block architectures, the camshafts are not directly interchangeable. The 1Z uses OEM 13501-78200 (or superseded 13501-78201/78202), which has specific lobe duration and lift tailored for the 3.0L displacement. The 2Z (3.5L) uses a different cam profile to accommodate increased air volume. Always verify your exact engine plate before ordering.
A loud, rhythmic ticking noise from the lower block area usually indicates lifter (tappet) or camshaft lobe wear. Because the 1Z is an OHV engine, worn lobes fail to lift the pushrods adequately, increasing the valve clearance beyond the factory 0.35 mm (cold) specification. If the lobe height measures below 41.50 mm, both the camshaft and the lifters must be replaced simultaneously to prevent immediate re-galling.
Unlike SOHC engines with top bearing caps, the OHV 1Z camshaft is secured inside the block using a front thrust plate. The two retaining bolts for this thrust plate must be torqued to 19 Nm (14 ft·lbf). Before inserting the shaft, thoroughly coat all journals and lobes with high-pressure assembly lube to prevent dry-start scoring during the initial engine break-in period.
