Fitment and Service Notes
The 1R-0749 is the Advanced Efficiency spin-on fuel filter on Cat’s heavy-bore electronic engines. The media rating matters here: 99% of particles at 3 microns and larger are captured, which is the level of protection high-pressure unit injectors need — a mechanical-era filter on an electronic engine is a slow-motion injector failure. The same element is shared across the 3406B/C/E family, the C10–C16 range, and the 3176/3196, so it turns up on excavators, generator sets and on-highway trucks alike.
On most applications the 1R-0749 is fitted together with the 1R-0750 secondary element, and the pair is changed at the same service. Before ordering, read the number stamped on your old filter — 1R-0749 (written 1R0749 on some labels) is the number to match. We supply high-quality aftermarket elements cross-referenced to the OEM number, confirm fitment against your machine serial before anything ships, and can bundle the 1R-0749/1R-0750 set in one shipment.

FAQ
Q: Which engines use the Caterpillar 1R-0749 fuel filter?
A: The 1R-0749 is the Advanced Efficiency spin-on fuel filter on Cat 3406B/C/E engines and the C-series electronic range — C10, C12, C13, C15 and C16 — plus the 3176 and 3196. Machines include 330D/336D excavators and XQ350–XQP500 generator sets. Confirm your machine serial before ordering so we match the exact variant.
Q: Is the 1R-0749 the same filter as the 1R-0750?
A: No. The 1R-0749 delivers 99% filtration efficiency at 3 microns, while the 1R-0750 is the 2-micron absolute secondary element. On most Cat applications the two are fitted together and changed as a pair — send us the numbers stamped on your old filters and we match the set.
Q: What does 99% efficiency at 3 microns mean?
A: It is the filtration rating of the Advanced Efficiency media: the element captures 99% of particles at 3 microns and larger. That level of protection is what high-pressure common-rail and electronic unit injectors need to stay alive in dirty-fuel markets.
Q: How do I order this filter from CN Machinery?
A: Message us on WhatsApp or email sales@cn-machinery.com with your machine model, serial number and the numbers on your old filters. Stock items dispatch in 3–7 days, FOB Shanghai or CIF to your port, with payment by T/T.
