APRA Europe
Automotive Parts Remanufacturers Association, the European trade association of the remanufacturing industry, based in Brussels. STP-Parts is a member.
CHRA
Centre Housing Rotating Assembly, the core assembly of a turbocharger: bearing housing, shaft, compressor and turbine wheel. Usually replaced completely during remanufacturing.
Core
A used original part that serves as the basis for industrial remanufacturing. The term comes from the US reman market.
Core broker
Intermediary who sources cores on the market, identifies, inspects and stores them and supplies them to remanufacturers. STP-Parts is a core broker.
Core charge
Another term for the core deposit, common in the US.
Core deposit
Amount the buyer of an exchange part pays in addition and gets refunded on return of the used part. Secures the remanufacturer's supply of cores.
Core management
Organising the return flow of used parts: collection, identification, inspection, storage and delivery to remanufacturers. The core business of a core broker.
Core return
Return of the used part to the supplier of the exchange part, usually against refund of the deposit.
Dual-mass flywheel (DMF)
Flywheel with two spring-coupled masses for vibration damping. Remanufactured by specialised companies; do not open as a core. German abbreviation: ZMS.
EHPS
Electro-hydraulic power steering: an electrically driven hydraulic pump with control unit supplies a conventional steering gear. Common from the 2000s onwards.
EPB
Electric parking brake. On brake calipers with EPB, an actuator motor sits on the caliper and is part of the core.
EPS
Electric power steering, electromechanical steering without hydraulics. Motor and control unit sit on the steering gear (pinion or axle-parallel EPS) or on the steering column.
ERN
European Remanufacturing Network, an EU-funded network whose studies document, among other things, the typical price of reman parts (60–80% of the new part).
Exchange number
Part number of a reman part, at Bosch for example beginning with 0 986. Differs from the number of the new part.
Exchange part
Remanufactured part sold against return of the used part. Synonyms: reman part, service exchange part.
Identification
Assigning a used part to a part number and variant based on type plate, OE number and design. The basis of every valuation.
Incoming inspection
Inspection of a core at the remanufacturer or core broker for identity, completeness and housing condition. Decides on acceptance or rejection.
LIN regulator
Alternator regulator with LIN bus connection to the engine control unit. Must be present on the core.
Lot
Larger quantity of used parts offered as a whole, type-sorted or mixed.
Mesh box (Gitterbox)
Stackable steel mesh container on a pallet footprint. Standard packaging for cores in lots.
OE number
Part number of the vehicle manufacturer (Original Equipment). The most important number for identification.
OEM
Original Equipment Manufacturer. In the core trade usually synonymous with original part.
Overrunning alternator pulley (OAP/OAD)
Alternator pulley with a one-way clutch that keeps torsional vibration from the belt drive away from the alternator. May be missing on the core.
Recirculating ball steering
Steering gear design for heavy vehicles in which a recirculating ball nut transmits the steering movement. Known in the trade as a steering box.
Reman
Short for remanufacturing.
Remanufacturer
Company that carries out remanufacturing on an industrial scale. Buyer of cores. German: Wiederinstandsetzer.
Remanufacturing
Industrial reconditioning: complete disassembly, cleaning, inspection, replacement of all wear parts, assembly to OE specification, test bench. The result is an exchange part with warranty.
Return conditions
Rules of an exchange programme under which a used part is accepted as a deposit return: variant, completeness, condition, deadline, packaging.
Steering box
Steering gear of recirculating ball design for trucks, buses and off-road vehicles.
Type plate
Label or stamping on the part with manufacturer, part number and often the OE number. Must be legible on the core.
Type-sorted
Separated by part type. A type-sorted mesh box contains only starters or only turbochargers.
Used part
A used, removed vehicle part. Not every used part is a core: only remanufacturable used parts with an intact housing count as cores.
VGT / VNT
Variable geometry turbine: turbocharger with adjustable guide vanes and actuator. The actuator is part of the core.
Wastegate
Exhaust bypass valve on a fixed-geometry turbocharger that limits boost pressure. Pneumatically or electrically actuated.
Wiederinstandsetzung
German term for remanufacturing. Not to be confused with Instandsetzung (repair of a single fault).
ZMS
German abbreviation for Zweimassenschwungrad, the dual-mass flywheel. See Dual-mass flywheel (DMF).
