Technical notes
The 528-8365 turbocharger group is the Caterpillar-numbered turbocharger assembly fitted to the 3512B Marine Auxiliary engine (serial-number prefix 8EM00001-UP) and to shared 3512 and 3512C arrangements such as generator-set and petroleum packages. For an in-service overhaul the matching cartridge (CHRA), part number 528-8366, is usually replaced rather than the complete group, which retains the original turbine and compressor housings and the mounting interface. Because turbocharger arrangements differ between 3512 ratings and applications, always confirm the engine serial-number prefix and the part number on the existing unit before ordering. The group is available new from Caterpillar or as a remanufactured exchange unit.

Frequently asked questions
- Does 528-8365 fit any 3512?
- It is the listed turbocharger group for the 3512B Marine Auxiliary (8EM00001-UP) and shared 3512/3512C arrangements. Always confirm against your engine serial-number prefix, as turbocharger arrangements vary across 3512 variants.
- Do I need the whole group or just the cartridge?
- For most in-service rebuilds the 528-8366 cartridge (CHRA) is sufficient; the complete 528-8365 group is used when the housing/mounting is also being replaced.
