This is the Garrett 887393-5005S, a new turbocharger, not a rebuild, for the EPA10 and GHG14 Detroit Diesel DD15 and DD16. It is common on the Freightliner Cascadia and 122SD and the Western Star 4900. It is Garrett’s replacement for the Holset HX55 turbo these engines were built with, including Holset 4033844H, 5358033H, 5457274H and 3787000H, and Detroit numbers A4720960799, A4720961199, A4720961399, A4720961599, A4720961699, A4720961999, A4720962099, A4720962299, A4720962399 and A4720962499. The full list is in the cross reference table.
The DD15 was built with more than one turbo, so check the tag. DD15 engines built with the BorgWarner wastegated turbo, Detroit A4720901480, take BorgWarner 57909882500, and no catalog lists one for the other. Low boost, oil in the charge pipes, shaft play or a damaged wheel are the usual reasons for replacement. Find the cause first, because a bad oil supply or debris will take out the next turbo too. Heavy truck turbos are matched by the number on the turbo tag.
Confirm Fitment Before You Order
The DD15 was built with more than one turbo and this one replaces many Detroit and Holset numbers. Check the number on your turbo tag against the cross reference list. Engines whose turbo carries Detroit A4720901480 take BorgWarner 57909882500 instead. Send us your turbo tag numbers and engine serial number and we will confirm the match. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
