Technical notes
107-7330 is the STANDARD (STD) size connecting rod (big-end) bearing pair for the Caterpillar 3500 engine family, including the 3512B marine engine. Each part number supplies two half shells for a single rod journal; a full 12-cylinder 3512B overhaul therefore requires twelve sets. Distributor data lists a 2.248 in bearing width and 144.45 mm outer diameter, with prior Cat numbers 7E-7997, 7N-2394 and 1W-7538 interchanging to this current number. Note for procurement: the candidate record labeled this as a 0.25mm undersize (U/S) bearing, but all reviewed sources describe 107-7330 as the standard-size bearing — a 0.25mm undersize for a reground crankshaft would carry a different Cat part number, which must be sourced separately.
Compliance
Replacement engine internal wear part with no standalone regulatory marking; conformity is governed by the parent Caterpillar 3500-series engine's emissions and classification approvals.

Frequently asked questions
- Is 107-7330 a standard or undersize connecting rod bearing?
- Every reviewed distributor and the Cat Parts Store list 107-7330 as the standard (STD) size bearing. It is not the 0.25mm undersize version; an undersize bearing for a reground journal would carry a different Cat part number.
- Does 107-7330 fit the 3512B marine engine?
- Yes. The Cat Parts Store application data lists 3512B among the 3508/3512/3516 family engines that use 107-7330, and distributors confirm 3508/3512/3516 fitment.
- How many bearings come in one 107-7330?
- One part number supplies a pair — two half shells for a single connecting-rod journal.
