Technical notes
The 8N-2001 is the cast oil filter base that bolts to the engine block and provides the mounting pad, threaded spuds and oil galleries for the spin-on full-flow lube filters on Caterpillar 3500-series diesel engines. Distributor and OEM listings show it fitting the 3508, 3508B, 3512, 3512B, 3516 and 3516B platforms used in GEN SET, industrial and petroleum engine arrangements, which share the same lubrication architecture as the 3512B marine rating. It is a structural/plumbing component, not a serviceable filter element; the replaceable filters (for example the 1R-0726 family) thread onto this base. Confirm bolt-pattern, port orientation and number of filter spuds against the engine's parts manual before ordering, since 3500-series filter-group configurations vary by arrangement and serial-number group.
Compliance
Mechanical engine component with no specific regulatory marking; verify fitment against the engine serial-number parts manual before installation.

Frequently asked questions
- Does the 8N-2001 fit the 3512B engine?
- Yes. Distributor and OEM application data list the 8N-2001 oil filter base across the 3500-series diesel family including 3508, 3508B, 3512, 3512B, 3516 and 3516B, which share the same lubrication-system layout as the 3512B marine rating. Always confirm against your engine's serial-number parts manual.
- Is the 8N-2001 a filter element I replace at service intervals?
- No. It is the filter base assembly, a structural casting that provides the mounting pad and oil galleries for the spin-on lube filters. The replaceable filter elements (such as the 1R-0726 family) thread onto this base; the base itself is replaced only if damaged or leaking.
- Does the 8N-2001 fit the gas G3500 engines?
- Available listings tie the 8N-2001 to the diesel 3500-series engines (3508/3512/3516 and their B variants). The spark-ignited G3508/G3512/G3516 gas engines are a separate variant and should not be assumed compatible without verifying against the specific engine arrangement's parts manual.
