Camshaft 13501-54050 for Toyota Hiace, Hilux and Chaser 2L Diesel

The 13501-54050 camshaft covers the widely used Toyota 2L 2.4-litre diesel fitted to the Hiace, Hilux and Chaser. A worn camshaft is one of the most overlooked causes of lost compression and rough idle on the 2L — yet it is routinely misdiagnosed as a fuel-pump or injector problem. This OEM-spec replacement restores the factory valve lift and timing profile, bringing back the low-down torque these engines are valued for in commercial, 4×4 and fleet use. TOSEN AUTO supplies it forged from alloy steel with induction-hardened lobes, 100% inspected, ready to install.

The 2L is the 2,446 cc SOHC 8-valve indirect-injection diesel used across Toyota’s light-commercial and 4×4 line-up through the 1980s and 1990s. Because the same engine code spans multiple body shells, fitment is driven by the engine code, not the body. Confirm you have the naturally aspirated 2L — not the turbo 2L-T and not the later 2.8 L 5L — before ordering. The 2L-T and 5L use different cam profiles and different OEM numbers; a 2L cam will run in a 2L-T but with the wrong valve timing for turbo operation, costing power and risking detonation.

The 13501-54050 is forged from chromium-molybdenum alloy steel and induction-hardened on the lobes and journals. The 2L’s valvetrain uses flat tappets that load each lobe flank in a narrow contact band; a soft or cast cam will show visible lobe wear within 20,000–30,000 km in commercial use. Forging aligns the metal grain along the lobe, and induction hardening produces a HRC 55–60 case over a tough HRC 25–32 core — the combination that lets the 2L survive lube-oil dilution and extended drain intervals common in fleet service.

After heat treatment, every camshaft is finish-ground to OEM journal diameter and lobe profile, then 100% inspected: journal runout under 0.04 mm total indicator reading, lobe lift within ±0.02 mm of the master 2L profile, surface finish free of grinding chatter, and overall straightness. Each part is oiled and wrapped in anti-corrosion paper for shipping.

• Lobe wear on the intake side — the 2L’s flat tappets are unforgiving of overdue oil changes. Worn intake lobes lean out the idle and produce a characteristic “miss” on one cylinder that a pump reset cannot fix.
• High-mileage grey smoke — retarded valve timing from a worn cam reduces effective compression, producing grey smoke that clears as the engine warms, then returns under load.
• Diesel knock after a rebuild — often the cam timed one tooth out, not a pump problem. Always verify the timing-belt marks and the injector pump timing after cam replacement.
• Cold-start deterioration — the 2L relies on stable low-rpm compression for cold starts; a worn cam is a leading hidden cause when glow plugs and compression test “fine”.

See our guide on bad camshaft symptoms for a full diagnosis, and our camshaft replacement cost breakdown before you commit to a rebuild.

1. Check bearing oil clearance with the old cam out; replace bearings if out of spec before fitting the new camshaft. A new cam on worn bearings fails fast.
2. Coat lobes and journals with assembly lube (high-ZDDP) for first start — critical for the 2L’s flat tappets.
3. Set valve clearance cold (intake 0.20 mm, exhaust 0.30 mm) after timing the belt. Re-torque bearing caps in the factory sequence.
4. Replace timing belt, tensioner and front seal at the same service — the 2L is an interference engine, so a belt failure bends valves.
5. Verify injector pump timing after the cam is timed; a tooth off on the cam throws spill-timing out.

• Original Toyota 2L lobe profile — correct lift/duration for 13501-54050, not a generic diesel blank.
• Induction-hardened lobes and journals for the 2L’s high-load flat-tappet valvetrain.
• Forged alloy steel with a tough core, 100% inspected for runout and surface finish.
• Factory-direct B2B pricing; sample orders accepted, volume pricing for distributors.
