Hanshin · LH · LU · LF · Four-stroke
Genuine, OEM and reconditioned spares for Hanshin-Hanshin four-stroke main engines — the Hanshin LH, the common-rail LH / LU and the Hanshin LU series — sourced beside Alang, shipped to India, UAE, Singapore & worldwide.
A century of diesel
Hanshin Diesel Works is founded in Kobe, Japan, building marine diesel engines for the Japanese merchant fleet.
Hanshin develops its LH medium-speed four-stroke trunk-piston marine diesel — compact, reliable power for coasters and fishing vessels.
The higher-output LU series broadens Hanshin’s range for cargo ships, tugs and offshore vessels.
Hanshin refines its four-stroke line with the cleaner-burning LF and EL engines for modern small craft.
Hanshin engines power thousands of small Japanese and Asian vessels; Wattmare keeps every LH, LU and LF generation running with genuine, OEM-equivalent and Alang-reconditioned spares.
Who is Hanshin
Hanshin — Hanshin Diesel Works of Kobe, Japan — builds the LH, LU and LF medium-speed four-stroke trunk-piston marine diesel engines. Compact, robust and famously reliable, Hanshin engines have powered coasters, fishing vessels, tugs and small cargo ships across Asia and beyond since 1919.
A single fleet can run the LH series (LH28L, LH34L, LH36L), the higher-output LU series (LU32, LU38, LU46), or the legacy LF / EL mains — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares across every Hanshin bore.

The complete guide
Wattmare is a specialist Hanshin engine spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for every generation of Hanshin-Hanshin four-stroke marine main engine, dispatched worldwide in 24–48 hours.
The four-stroke engines on this page are built in-house by Hanshin Diesel Works of Kobe, Japan — a marine-engine maker since 1919. Hanshin’s LH, LU and LF medium-speed trunk-piston diesels have powered coasters, fishing vessels, tugs and small cargo ships across Japan and Asia for generations. We supply spares across all of them.
The single most important question on any Hanshin-Hanshin order is whether the engine is an LH, an LH or an LU series. The Hanshin LH is camshaft-controlled — fuel pump, fuel cam, chain drive and mechanical exhaust-valve gear. The LH / LU and the Hanshin LU series are electronically controlled, replacing the camshaft with a common-rail supply unit, rail valves, flow-control units (FCU) and hydraulically actuated exhaust valves. Liners, covers, crowns and bearings are broadly common by bore, but injection and actuation parts are entirely different — always give us your exact LH / LU designation.
For every Hanshin LH, LU and LF bore we stock cylinder liners, cylinder heads and covers, piston crowns and skirts, piston rings, connecting-rod and main bearings, fuel injection valves, fuel pumps and plungers, inlet and exhaust valves, camshaft parts and turbocharger spares — genuine, OEM-equivalent and Alang-reconditioned.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Hanshin LH four-stroke engines. That gives Wattmare direct access to genuine, low-hour parts that are slow or costly to source from distributors, at a fraction of new-part cost and lead time. For hard-to-find LH fuel pumps, chain drives, liners or running gear, this is the fastest source in the world. Browse our reconditioned marine spare parts range, the wider main engine spare parts category, or sister brands like MAN engine spares and Mitsubishi UEC.
Send your Hanshin engine make and model with a photo or part number on WhatsApp, or use the quote form. We confirm availability and price — usually within the hour — and dispatch in-stock items within 24 hours. Typical air-freight transit is 12–18 hours to the UAE, 16–24 to Singapore, 20–26 to Greece and Turkey, and 28–36 to Northern Europe.
FAQ
Yes — cylinder liners are one of our strongest Hanshin-Hanshin lines. We carry original-bore and reconditioned liners for the LH and LH, plus the rest of the LH range (LH28L to LU50), honed to OEM tolerance with measurement reports. Most legacy LH liners are recovered and reconditioned beside Alang.
The Hanshin LH is a camshaft-controlled (mechanical) four-stroke — fuel pump, fuel cam and mechanical exhaust-valve actuation. The LH / LU and the Hanshin LU series are electronically controlled, replacing the camshaft with a common-rail supply unit, rail valves, flow-control units (FCU) and hydraulically actuated exhaust valves. Liners, crowns and bearings are broadly similar by bore, but the injection and exhaust-valve actuation parts are completely different — always quote your exact the LH and LU range or LU series model.
We cover the full Hanshin four-stroke range — the LH series (LH28L, LH31L, LH34L, LH36L, LH40L, LH41L, LH46L), the higher-output LU series (LU28, LU32, LU35, LU38, LU40, LU46, LU50), and the legacy LF / EL engines — every Hanshin bore.
Reconditioned parts ship with inspection reports, dimensional measurements and photographs, and are accepted by class societies (Lloyd’s Register, DNV, ABS, BV, ClassNK, RINA) on survey. Genuine Hanshin parts carry full material and test certificates.
In-stock items dispatch within 24 hours from Bhavnagar. Typical air-freight transit to the UAE (Dubai, Jebel Ali, Fujairah) is 12–18 hours. Singapore is 16–24 hours, Greece and Turkey 20–26, and Northern Europe 28–36.
Yes — fuel injection valves, injector nozzles, high-pressure fuel pumps, plungers and barrels for Hanshin LH engines, plus common-rail supply units, rail valves, flow-control units (FCU) and injection equipment for LH / LU and LU series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Hanshin / Hanshin) with full certificates. OEM-equivalent are quality aftermarket parts at 30–50% less. Reconditioned are low-hour parts recovered from Alang, inspected and certified to OEM tolerance, at up to 70% less with a 30-day warranty.
Yes — obsolete Hanshin LH parts are our specialty. Beside Alang we recover low-hour fuel pumps, chain drives, liners, crowns and running gear from LH-powered vessels being dismantled, then inspect and certify them. For the LH and LU range and LH engines this is often the fastest source in the world.
Yes — we supply turbocharger spares, chain drives, fuel pumps, camshaft parts, bearings and complete running gear for the Hanshin LH, LU and LF series, genuine and Alang-reconditioned.
Send your engine model and a photo or part number on WhatsApp (+91 96647 18068), or use the quote form. We confirm availability and price, usually within the hour — whether you need genuine, OEM-equivalent, used or reconditioned parts, or a complete overhaul kit.
We ship from Alang/Bhavnagar to the UAE, Dubai, Singapore, Greece, Turkey and every major port worldwide in 24–48 hours. Parts are export-packed with VCI wrapping, wooden crates and palletisation, with photos shared before dispatch and full export documentation included.
