Turbocharger assembly for the 51.8 litre 3512, 3512B and 3512C V12 engine block. Two chargers are fitted per engine, one on each bank, so quantity must be agreed before a price is agreed. Eight separate charger families are catalogued against this block depending on duty, from TV9211 and TW9211 through GT6041BL and GTB4708, and the 102-029 range sits inside a single family with six adjacent numbers. Remanufactured releases carry exchange prefixes.

| Quantity Before Price | Each bank carries its own charger, so a figure quoted for one unit covers half an engine and the second bank is a separate line |
|---|---|
| Six Neighbours In One Range | 102-0290, 102-0294, 102-0296, 102-0297, 102-0299 and 102-0301 are six different chargers, not six names for one |
| Exchange Prefixes | 0R, 10R and 20R in front of a number mark remanufactured supply and bring a core obligation with them |
| Family Mapping | TV9211 covers 102-0294 and 102-0296, TW9211 covers 7W-9409, GT6041BL covers 0R7430 and 416-2723, BTV7511 covers 259-8424 |
| Marine And Genset Split | The same block is sold as 1750 hp marine, 1275 kVA at 1500 rpm generator and 955 kW industrial, and the charger follows the duty rather than the block |
| Caution – Smaller Engine Numbers Attached | 4P-2783, 4W-1225 and 4P-4681 belong to the six cylinder medium engines and appear in this search only because sellers list every block in one heading |
| Caution – Placeholder Prices | Figures under a few hundred yuan and lots quoted per hundred pieces are deposit or listing placeholders, since no 51.8 litre charger ships at that money |
| Caution – Housing Match | Turbine housings differ between marine and generator builds on the same family, so a charger from the wrong duty bolts on and then runs off its map |
| Caution – Pairing On Rebuild | Replacing one bank leaves an older unit opposite it, and mismatched wear shows as an imbalance between banks rather than as a single fault |
| Related Components | CHRA cartridge, turbine housing, compressor housing, actuator, fitting kit, oil feed line, oil return line, exhaust bellows, air cleaner element |
Two, because the block is a V12 with an exhaust manifold on each side and the air is compressed once per bank. That single fact explains most of the confusion in this category, since a headline price usually refers to one unit while a buyer planning a rebuild is thinking about a pair.
Because the block has been built for three very different duties over four decades. A generator running at fixed speed, a marine unit pushing a hull and a haul truck climbing a grade all need different turbine trims, and the family name records which trim was chosen rather than which engine it bolts to.
A deposit that is returned only when the old unit comes back complete and rebuildable. Housings with cracks, a bent shaft or a missing actuator turn that deposit into a charge, and the invoice reads lower than the eventual cost until the core has been accepted.
BTV7511, with 466739-5001S and 1152257 alongside it.
Remanufactured supply rather than new production.
