Genuine Caterpillar 1R-1807 Advanced High Efficiency oil filters (pack of 2) for reliable engine protection and consistent oil flow in heavy-duty equipment.

These authentic CAT 1R-1807 oil filters are designed for heavy machinery and diesel engines where OEM fit and predictable performance matter.

Use your machine's service manual to verify fitment before purchase.

What makes this CAT 1R-1807 oil filter different from aftermarket options?

The CAT 1R-1807 is manufactured to meet Caterpillar’s internal standards for filtration media, bypass performance and structural durability. Choosing an OEM filter reduces uncertainty about material quality and compatibility with CAT engines and systems.

• OEM manufacturing tolerances for consistent thread and sealing surface fit
• Filtration media tuned to match Caterpillar bypass and flow expectations
• Specified height (262 mm) and diameter (108 mm) for guaranteed clearance and installation
• Sold as a convenient pack of two for planned maintenance intervals

How do I confirm this filter fits my equipment?

Verify fitment by consulting your equipment owner’s manual or parts catalog and matching the part number 1R-1807. Check the filter’s thread and physical dimensions against the housing before ordering.

• Thread size: 1.125 - 16 - UNF — confirm matching housing threads
• Height: 262 mm — verify available clearance in the filter bay
• Diameter: 108 mm — ensures proper seal and access for removal
• Part number 1R-1807 — reference in parts diagrams for exact compatibility

How should I install and handle these oil filters during maintenance?

Installation follows standard spin-on filter procedures: clean the mounting surface, lightly oil the gasket, hand-thread the filter, and tighten to the torque or turns specified by the equipment manual. Replace filters at the intervals recommended by your service schedule and dispose of used filters according to local regulations.

• Clean sealing surface before installing to prevent leaks
• Lubricate gasket with clean engine oil for an improved seal
• Hand-tighten and follow manufacturer torque or turn recommendations
• Replace both filter and oil at scheduled service intervals for best results

Why buy a two-pack of CAT 1R-1807 filters?

A two-pack gives technicians and fleet managers backup filters for routine maintenance or multi-machine service visits without needing an extra parts order. It reduces downtime by keeping an extra genuine filter on hand and simplifies inventory for scheduled oil changes.

• Two filters per purchase for immediate next-service coverage
• Simplifies parts management for shops and fleet services
• Ensures both filters are identical OEM units for consistent performance

Who is this for: This pack of CAT 1R-1807 oil filters is aimed at heavy-equipment owners, fleet managers, service shops and technicians who prioritize OEM compatibility and predictable service life. If you operate Caterpillar machines or equipment that lists 1R-1807 as the correct part number, this genuine two-pack helps keep maintenance efficient and aligned with manufacturer recommendations. Always confirm fitment with your machine’s documentation before installation.
