Technical notes
The 20R-1264 is a Cat Reman electronic fuel injector for the 3500-series engine family, including the 3512B marine/genset platform plus the 3508/3516 variants and 3512C/3516C. One unit installs per cylinder in the cylinder head, metering and atomizing fuel under electronic control via the engine ECM. It is supplied remanufactured on an exchange basis, superseding earlier numbers 392-0200, 386-1752, 10R-1284 and 0R-9944, so verify the number cast on the existing injector before ordering. Fitment caution: the 3500 family uses several distinct injector part numbers across rating and emissions levels (e.g. 20R-1266 on some 3512B/3516B builds), so confirm the engine serial/arrangement number rather than the engine model alone. A refundable core deposit applies and the used core must be returned.
Compliance
Material certification and Caterpillar OEM traceability documentation available on request for the remanufactured unit and its returned core.

Frequently asked questions
- Does the 20R-1264 fit the Caterpillar 3512B engine?
- Yes. Distributors list it for the 3508/3512/3516 family including 3512B, 3508B, 3516B and the 3512C/3516C variants, plus SR4B/SR4BHV gensets. Because the 3500 family uses multiple injector numbers across ratings and emissions levels, confirm the engine serial/arrangement number before ordering.
- Is 20R-1264 new or remanufactured, and is a core required?
- It is a remanufactured (Cat Reman) injector sold on an exchange basis. A refundable core deposit of roughly $200-$366 per injector applies and the used core must be returned to avoid the charge.
- What part numbers does 20R-1264 replace?
- It supersedes and cross-references 392-0200, 386-1752, 10R-1284 and 0R-9944 (and is associated with 229-0197). Match the number on the injector being replaced to confirm the correct unit.
