Cross-Reference / Manufacturer Part Numbers
The supplied Moto Mania item is an unbranded aftermarket set. The following CMPO manufacturer and OE/OEM references are provided for identification and compatibility checking; they do not mean the supplied parts are genuine CMPO-branded items.
- Oil filter / strainer cap: CMPO OLFC006 — OE/OEM reference 124901003, EAN 5057645144953
- Oil filter strainer spring: CMPO OLFSS002 — OE/OEM reference 140200032, EAN 5057645167402
- Mesh thimble oil strainer: CMPO OLST003 — OE/OEM reference 140200029, EAN 5057645114901
Common Engine Families
This oil-strainer arrangement is widely used on 4-stroke scooter engines including 139QMA / 139QMB 50cc engines and related 152QMI / LJ1P52QMI / 157QMJ 125–150cc GY6-style families. Engine code alone should still be checked because individual manufacturers used several crankcase variants.
What the Oil Strainer Does
The mesh screen traps larger particles and debris before they circulate through the engine lubrication system. The spring keeps the screen correctly loaded against its seat, while the threaded cap closes the housing and provides access for cleaning during an oil service.
When to Replace It
- Damaged or distorted mesh screen
- Missing or weakened strainer spring
- Damaged, rounded or leaking filter cap
- Lost components during an oil change
- Engine rebuild or crankcase replacement
Important Compatibility Checks
- Confirm the engine is 4-stroke; do not use this listing for a 2-stroke engine simply because the scooter has a similar model name.
- Compare the cap diameter, thread, hex-head shape, spring and thimble-screen dimensions with the parts currently fitted.
- Check the model/frame or engine code where shown above.
- Inspect the existing cap seal/O-ring and replace it separately if required.
