Cummins NTA855 parts

The NTA855 — the 14-litre 855 in its turbocharged, aftercooled form — is probably the most widely distributed Cummins engine in East African standby power. It covers roughly the 250 to 400 kVA band, and its parts economy is mature: almost everything is available, from several sources, at several quality levels. That is a good thing and a trap at once, because the 855 is also the family where counterfeit parts circulate most freely in the regional market.

Every number on this page is catalogued for the NTA855 in genset and industrial applications. Where a number also fits the naturally aspirated NH/NT variants we note it in the description rather than assuming it, because the turbocharged and aftercooled builds differ in pistons, injectors and cooling parts in ways that matter.

This is the family where we are most insistent about the tier being stated in writing. A counterfeit 855 injector or water pump is easy to buy in this region, visually convincing, and will fail early enough to cost far more than the saving. We source Tier 1 through authorised distribution in the UAE with documentation available on request, and where we offer Tier 2 it is a named brand — Fleetguard, Donaldson, Baldwin, Mann and similar — bought through that brand's own authorised distributor, not an unbranded equivalent in a printed box.

For a quotation, send the engine serial number and the CPL. On the 855 the CPL is what separates several generations of piston, injector and cam design that share an engine name. A photograph of the rating plate covers it if you do not have the paperwork.
