Description

Yanmar 6EY22LW / 6EY22ALW / 6EY22LWS / 6EY22ALWS Marine Engine Parts Catalog

This is the official Yanmar parts catalog for the 6EY22LW, 6EY22ALW, 6EY22LWS and 6EY22ALWS marine auxiliary engines, issued under document number 0CH10-M38301EN. It covers the full engine — from the cylinder block casting and cylinder liners, through every cover, seal, gear housing and bearing, all the way out to the turbocharger, governor, control panel and the special service tools. Every figure section lists the part numbers, descriptions, quantities and applicability notes you need to identify and order the correct Yanmar genuine part for the engine serial number you are working on.

Separate cylinder head sections for the M.D.O. and H.F.O. specifications, plus intake and exhaust valves, valve seats, guides, springs, rotators, retainers and stem seals. The camshaft section covers the complete shaft assembly, governor gear, cam gear, bolt kits and the working valve device including tappet, swing arm and push rod assemblies. The rocker arm section lists the rocker supports, arms, bushes, adjusting screws and lock nuts for both intake and exhaust sides.

Exhaust Manifold, Turbine and Piping (Figs 48–54, 60–80)

The full turbocharger coverage spans TPS48F, TPS52F, A130, A135, MET18 and MET22 type turbines, with separate figures for M.D.O. and H.F.O. variants and pick-up specifications. You get the turbine assembly, mounting hardware, brackets, water feed pipe, cooling pipe, blower washing pipe, washing device, drain pipe and exhaust outlet pipe variants (300A, 350A, 400A, angle 60 and MET22 outlet). The exhaust manifold and connecting pipe figures show gaskets, expansion joints, supports and turbocharger inlet gaskets by model.

Cooling and Intercooler (Figs 81–84, 123–158)

Inter cooler assembly by production range (including the 2020+ low-temp intercooler), air duct for TPS48F, TPS52F and MET22 turbines, and every high-temp and low-temp cooling water pump variant with the correct serial-number break (from E00700, from E00673, from E00640 and to-E00670 / to-E00672 / to-E00459 prefixes). Also includes the water pump casing, cover, shaft, impeller, mechanical seal, bearings, thermostat assemblies, cooling water auto sluice valves, collecting pipes, drain pipes and the low-temp and high-temp piping between pump, cooler and intercooler.

Lubricating Oil System (Figs 93–122)

Lub. oil pump assemblies and variant parts, safety valve, priming pump (VLG-5C 50Hz and 60Hz), oil cooler, pressure regulating valve, dipstick, strainer and by-pass filter sections, oil thermostat, oil pipes for turbine, governor, generator, CJC filter, priming, cooling water sluice valve and fuel injection pump pinion oiling.

Why a Complete Parts Catalog Matters

Yanmar’s EY22 family is built in several closely related variants, and the same part can look identical across a 6EY22LW and a 6EY22ALWS while carrying a completely different part number. This catalog handles that complexity directly — most figure sections carry separate A/B/C/D/E applicability columns plus serial-number notes (e.g. “from E00700”, “from E00673”, “E/#1628”) so the exact part for the exact engine is the one you order, not the one that happens to be listed first. That saves the guess-and-return cycle that costs a vessel days in port.

The catalog also resolves the parts that are easiest to get wrong on the EY22: the different H.F.O. and M.D.O. fuel injection pumps, the model-specific crankshafts, the six turbocharger families, the four cooling water pump variants by serial range, the three governor types and their dedicated driving devices, the four air assist device variants and the three fuel cut device configurations. When the engine is already stripped down, having the illustrated exploded view in front of you is what keeps the reassembly moving.

Built for Real Workshop Use

The parts list tables in this PDF give you the item number that matches the callout on the illustration, the part number, the description and the quantity per engine. Rebuilders use the callout numbers to keep fasteners with their correct assemblies; purchasing teams use the part numbers and applicability columns to build accurate requisitions; crew use the exploded views to confirm that the turbocharger or governor they are looking at is the variant they think it is. The supplementary figures added from 2020 (306–312) cover the low-temp intercooler, the low-temp drain pipe, the low-temp air pipe, the low-temp pipe on the intercooler-to-oil-cooler run, the cylinder fresh-water drain pipe and the low-temp digital thermometer bracket, so the catalog stays current with later production engines.
