Product Description
Camshaft 13511-1574 135111574 for HINO H07D Engine
Premium Engine Camshaft OEM 13511-1574 135111574 for HINO H07D 7.4L Diesel Engine — 45# Forged Steel, HRC 56-59 Hardness, Direct Replacement
The Engine Camshaft with OEM number 13511-1574 (135111574) is a verified direct-fit replacement designed for HINO H07D 7.4L inline-6 diesel engines. This camshaft serves as the critical component controlling valve opening and closing timing, directly determining engine breathing efficiency, power output, and combustion quality.
The camshaft functions as the "brain" of the valvetrain system. As the crankshaft rotates, the camshaft — driven by timing gears — rotates at half the crankshaft speed, precisely actuating intake and exhaust valves through lifters and pushrods. Each cam lobe profile is engineered to open valves at exactly the right moment and hold them open for the optimal duration, ensuring complete cylinder filling and efficient exhaust scavenging.
Verified Performance Signals
- Material Hardness: Forged from 45# carbon steel, with a verified hardness of HRC 56-59 on the cam lobe surface — providing exceptional wear resistance and fatigue strength under continuous high-load diesel operation.
- Precision Manufacturing: All camshafts are produced using CNC machining, ensuring lobe profile accuracy and consistent journal dimensions for proper bearing fitment.
- 100% Pre-Delivery Testing: Every camshaft undergoes 100% inspection before shipment, including dimensional verification and surface hardness testing.
- OEM Cross-Reference Verified: Replaces HINO OEM number 13511-1574 / 135111574. Related alternate numbers include 135111572, 135111573, 13511-1573, S135111574, S135-111574.
Failure Symptoms — When to Replace
Worn or damaged camshafts manifest through several recognizable symptoms. Replacing at the first sign prevents cascading valve train damage and costly engine overhaul:
- Noticeable power loss — the engine feels sluggish, takes longer to accelerate, or lacks the torque it once had due to improper valve timing and reduced cylinder filling.
- Abnormal engine noises — tapping, rattling, or ticking sounds from the top end, caused by excessive cam lobe wear or reduced valve lift.
- Rough idle and misfiring — inconsistent valve operation leads to uneven combustion, causing vibration at idle and potential misfire codes.
- Poor fuel efficiency — incomplete combustion due to compromised valve timing results in increased fuel consumption.
- Excessive vibration — worn camshaft bearing journals or damaged lobes cause abnormal engine vibration felt through the steering wheel or the entire vehicle.

Installation & Maintenance Recommendations
IMPORTANT: Camshaft replacement is a precision engine repair. Professional installation by a qualified diesel mechanic is strongly recommended. Incorrect valve timing can cause catastrophic engine damage.
Installation Guidelines (Reference Workshop Manual)
- Remove the old camshaft following the HINO H07D service manual procedure. Record timing mark positions before removal.
- Inspect camshaft bearings for wear, scoring, or excessive clearance. Replace bearings if necessary — camshaft bearing installation depth is critical for proper oil gallery alignment.
- Lubricate the new camshaft generously with engine assembly lubricant before installation.
- Align timing marks precisely. The H07D uses a gear-driven camshaft system — verify proper gear mesh and timing alignment.
- Torque specifications: Consult the HINO H07D workshop manual for the exact torque values for the camshaft timing gear bolt and bearing cap bolts. Do not use generic torque values for this critical application.
- Valve clearance adjustment: After installation, adjust intake and exhaust valve lash to HINO OEM specifications.
- Rotate the engine by hand through two complete revolutions to verify proper timing and valve-to-piston clearance before starting.
Maintenance Schedule
- Oil change: Use high-quality diesel engine oil meeting HINO specifications. Change at recommended intervals to protect cam lobes.
- Valve clearance inspection: Check and adjust valve lash every 40,000-50,000 km as part of routine engine maintenance.
- Visual inspection: Inspect camshaft and bearing condition whenever the cylinder head is removed for any reason.
- Replace if: Cam lobe wear exceeds 0.2mm lift reduction, or journal wear exceeds OEM clearance limits.
Packaging & Supply
- Each camshaft is protected with anti-rust coating and wrapped in honeycomb fabric, then packed in a heavy-duty wooden case with foam padding.
- Packing size: 91 * 7.5 * 7.5 cm.
- Suitable for: Fleet maintenance departments, diesel engine rebuild shops, parts distributors, and wholesale buyers.
- MOQ: 1 set. Bulk pricing available.
