Purpose-built for Caterpillar’s heavy-duty diesel fuel systems, the 20R-5036 is an official Cat Reman common rail fuel injector (Injector GP Fuel) for C9.3 and C9.3B engine platforms. It carries multiple aliases for cross-channel parts lookup: the core OE number is also written as 20R5036, while widely accepted replacement numbers include 456-3493 (4563493) and 363-0493 (3630493). Prefix variants like CA20R5036 and CA4563493 appear in aftermarket catalogs, and low-confidence cross numbers require full validation before purchase. Limited aftermarket listings reference C9 engine compatibility, which requires case-by-case verification.

This injector meters, atomizes, and delivers diesel fuel into the combustion chamber at precise timing, volume and spray pattern to sustain consistent engine performance across demanding conditions. It is listed as compatible with a broad range of CAT equipment, including 336E/336F excavators, 966K/972K wheel loaders, D6T/D7E track tractors, 627H scrapers, M2 series motor graders and 568 FM forestry equipment, with additional aftermarket models including 340E, 340F, 349E and 349F.

It serves B2B customers including diesel repair shops, injection workshops, fleet owners, mining contractors, equipment dealers and global parts distributors. Because Caterpillar engines use varying arrangements, emissions calibrations and injector trim files, all orders require compatibility confirmation via machine serial number, engine serial number, original injector number and official parts catalog data. Units are available across channels as genuine new, Cat Reman, rebuilt, remanufactured or aftermarket replacements to match diverse budget and repair needs.
