Product Description
John Deere Engine ring R123575
1. Product Overview
John Deere Engine ring R123575 is listed under source title “RING O”. It is classified for this batch as engine ring within the sealing, retention, or piston-ring function system. The source record does not establish an exact engine model. Confirm the complete engine model, serial number, arrangement, and installed reference before ordering.
2. Function and Operating Principle
An engine ring may seal, retain, space, or control oil depending on its installation. If it is a piston ring, profile, coating, end gap, side clearance, and groove position are critical; the title alone may not establish the exact duty.
The ring uses controlled tension, geometry, or groove fit to maintain contact or retain a component. Functional direction and installation orientation must come from the exact parts and service documentation.
3. Application Status
| Manufacturer / brand | John Deere |
|---|---|
| Part number | R123575 |
| Component category | Engine ring |
| System | Sealing, retention, or piston-ring function |
| Evidence level | C — Component identity only |
| Engine application | Not established by the supplied record |
4. Typical Signs That Inspection May Be Required
| Observation | Possible significance |
|---|---|
| Loss of sealing or retention | May indicate wear, breakage, incorrect installation, or groove damage. |
| Abnormal oil consumption or blow-by | If piston-related, the complete ring pack, piston, and liner require evaluation. |
| Visible cracking, loss of tension, or scoring | Requires replacement and inspection of mating components. |
| Repeat failure | Can point to incorrect part selection, clearance, orientation, or system conditions. |
These observations are inspection triggers rather than a confirmed diagnosis. Evaluate the complete engine system and follow the applicable manufacturer service information.
5. Inspection and Replacement Guidance
- Confirm whether the item is a sealing, retaining, thrust, or piston ring.
- Inspect the groove and mating surfaces.
- Check orientation and measured clearance using approved documentation.
- Confirm size, profile, material or coating specification, and engine variant.
6. Information Required Before Ordering
- Complete engine or equipment model.
- Engine serial number and arrangement or configuration number.
- Installed part reference and clear photographs of the identification label.
- Installation position and related assembly information.
Compatibility notice: Verify R123575 against serial-number-specific parts documentation before purchase or installation. Do not select the component by appearance or part-number similarity alone.
