Champion CH48110-1 Oil Filter: Application Guide

Description

The Champion CH48110-1 is a spin-on aviation oil filter used on specific piston-engine and filter-adapter installations. Do not select it solely because a marketplace page lists a familiar aircraft or engine family. Confirm the exact engine model, airframe serial number, installed adapter, modifications, and current manufacturer application data before purchase or installation.

CH48110-1 quick reference

Is the CH48110-1 compatible with my aircraft?

Compatibility cannot be answered reliably from “Cessna 172,” “Piper Cherokee,” or “Lycoming O-360” alone. Those families span multiple engine variants, serial-number ranges, adapters, and field modifications. Champion’s current AV-14 aviation catalog contains engine and aircraft application tables and specifically warns that modified installations may require a different filter part number.

Use this verification sequence:

1. Identify the complete engine model and serial number from the data plate and records.
2. Identify the installed filter adapter and any conversion kit or field approval.
3. Check the aircraft serial number and installed-engine configuration.
4. Review the current airframe and engine maintenance or parts data.
5. Cross-check the latest Champion application catalog and technical publications.
6. Have the appropriately authorized maintenance professional resolve any conflict before ordering or installation.

CH48110-1 versus CH48111-1

Champion’s catalog groups CH48110-1 and CH48111-1 together in application material and describes them as interchangeable in a stated context, while also publishing adapter-specific tables and modification cautions. That is why a simple “replacement for” statement is insufficient. Clearance, adapter, bypass configuration, and approved application data still need to be checked for the actual installation.

Filter construction and purpose

Champion describes its aviation oil filters as full-flow filters using layered filtration media supported by a corrugated steel center tube and a heavy steel mounting plate and case. Its official oil-filter overview specifically notes the shorter stud on the CH48110-1 for installations with limited clearance.

An oil filter supports contamination control; it does not replace correct oil selection, change intervals, engine inspection, filter-media examination, oil analysis when appropriate, or investigation of abnormal findings. Follow the engine and filter manufacturers’ current instructions.

Before ordering

• Confirm the complete part number, including the “-1” suffix.
• Inspect listing photographs cautiously; packaging images are not applicability evidence.
• Check seller identity, traceability, packaging condition, and date or shelf-life guidance.
• Review Champion’s current technical publications, including any service letters or bulletins.
• Confirm that the item has not been superseded for the specific installation.
• Do not install a filter with damaged threads, case, seal, packaging, or uncertain provenance.

Installation and post-installation checks

Installation torque, gasket preparation, safetying, leak checks, engine run, records, and filter removal procedures must come from current applicable maintenance data. Do not copy a torque value from an unrelated filter or online forum. After maintenance, the responsible person should complete the required inspections, operational checks, and records before return to service.

Where this filter fits in annual planning

If an oil and filter change is planned during an annual, add the confirmed part number to the aircraft-specific annual inspection supplies checklist. Keep the item unopened until the installation is verified, and retain the invoice, packaging, and traceability information with the maintenance records as appropriate.
