SDEC Quote-Ready Parts
Quotes confirmed after machine model, engine model and part number compatibility checks.
Water pump and oil pump
SDEC Generator Water Pump
Water pump sourcing across the SDEC generator engine range. These are four separate engine platforms, not one part: the SC4H is a four-cylinder 4.3 L unit while the SC13G is a six-cylinder 12.88 L unit, so the water pump differs by series and in most cases by rating within a series. We source for all of them, but each quote is built against one specific engine — send the full nameplate code (for example SC9D220D2, not just SC9D) and the engine serial number.
Piston, liner and ring kits
SDEC Piston Liner Kit
Piston, liner and ring kits for SDEC engine overhaul and genset maintenance. The expensive mistake on these kits is ordering across liner types. The SC7H runs dry liners, which are pressed into the block; the SC8D and SC9D run wet liners that seal directly against coolant. A wet-liner kit therefore includes the lower liner O-rings and the top flange seal and a dry-liner kit does not, so the two are not interchangeable whatever the bore. Bore on its own is not enough either: the SC8D and SC9D share a 114 mm bore but run 135 mm and 144 mm strokes, so their pistons differ in compression height even where the liner looks identical. Send the full nameplate code, the engine serial number, and tell us whether the block has been rebored, since oversize pistons carry their own part numbers.
Fuel injector and fuel pump
SDEC Fuel Pump
Fuel pump quote support for SDEC diesel engines in genset and industrial equipment use. Injection pumps follow the calibration rather than the series: one SC9D covers many power ratings and each rating has its own pump part number and fuelling map, which is why a quote needs the full nameplate code (SC9D310D2, not SC9D). Two further things decide the part — whether the engine is mechanically governed or electronically controlled, and the emission stage it was built to. If the engine plate is unreadable, photograph the plate on the pump itself. The pump carries its own number, and on a used machine that is often the only reliable identification left.
Starter and alternator
SDEC Alternator
Alternator and charging system parts for SDEC-powered gensets and construction machines. Four things identify an alternator and the engine series is only a starting point: system voltage (24 V across most of this range, though 12 V appears on smaller industrial builds), rated output in amps, the mounting foot and bracket pattern, and the pulley. Single-groove, multi-groove and poly-V drives all turn up on the same engine family depending on what else the machine has to drive. Counting the pulley grooves and photographing the mounting feet identifies the unit faster than any model number. Worth ruling out first: a charging complaint is as often a slipping belt, a corroded earth strap or a failed regulator as it is a scrap alternator.
Cooling system parts
SDEC Oil Cooler
Oil cooler and gasket parts for SDEC diesel engines operating in hot oilfield and construction environments. This listing spans four separate engine platforms — the 6.44 L SC7H, the 8.82 L SC9D, the 10.5 L SC11CB and the 12.88 L SC13G — and core size scales with the engine, so nothing crosses between series. Most enquiries that reach us as oil cooler turn out to need the housing gasket set and O-rings rather than a complete assembly; those are the parts that fail and they cost a fraction of a core. The distinction that matters is where the oil is going: an external weep is usually gaskets, while oil found in the coolant or coolant in the oil means the core itself has failed.
