Cummins KTA19 parts

The KTA19 is a 19-litre inline six that has been in service long enough across East Africa that a significant share of the units still running are on their second or third life. It sits under 400 to 600 kVA sets, drilling packages and a good deal of older marine auxiliary plant. Parts availability is generally good, which makes it one of the families where the tier question matters most: for many KTA19 components there is a genuine option and a genuinely good aftermarket option, and the price gap is wide.

The numbers on this page are catalogued for the KTA19 across genset and industrial duty. Because the family is old, superseded numbers are unusually common — a part ordered by a number printed in a 1990s manual will often supersede two or three times before it reaches the current number. Every alternate number we hold is listed in the Cross-references column on this page, and it is searchable, because buyers routinely search the number stamped on the old part rather than the one that will actually ship.

Wear on high-hour KTA19s tends to show up first in the fuel system and the cooling circuit. Injectors that have gone long past their service interval will pass enough fuel to keep the engine running while quietly washing the bores; by the time smoke and oil consumption make the case obvious, liners and rings are usually in scope too. If you are pricing injectors on a high-hour unit, it is worth pricing an overhaul kit in the same enquiry so you can see both numbers before deciding.

For a quotation, send the engine serial and the CPL. On this family the CPL is the single most useful thing you can give us, because it resolves most of the supersession ambiguity in one step. A photograph of the rating plate is enough if the CPL is not written down anywhere.
