The original record names this XCMG loader disc with two references: ZL40.A.30.1 and ZL40.A.30. The punctuation and number depth may indicate an individual component, assembly family or drawing position, but this page does not prove that the references are interchangeable. First resolve which number appears on the component or parts documentation.
Resolve the Two References
| Source references | ZL40.A.30.1 and ZL40.A.30 |
|---|
| Product type | Disc component |
|---|
| Application | XCMG loader assembly; exact position requires confirmation |
|---|
| Evidence | Component marking, drawing position, both-face photos, dimensions, interfaces and machine serial |
|---|
Do not remove periods or assume ZL40.A.30.1 is automatically the same as ZL40A.30.1. Catalog punctuation can vary, but a match needs dimensions or a verified supersession record. If a parts drawing is available, send the assembly number and item position.
Build a Comparison Sheet
Record outside diameter, inside diameter, thickness and any centre spline, pilot, tabs, holes or passages. Photograph both faces next to a scale and note chamfers, steps, grooves, coatings or directional marks. Measure several positions because a worn disc may be tapered.
The listing does not state the disc function, material, hardness or wear limit, and it does not claim the references are a supersession pair.
Check the Assembly Around the Disc
Inspect the mating plate, hub or carrier, shaft, flange, retainers and bearing support. Uneven face contact can result from runout or stack misalignment; fretting can indicate movement; and heat marks may point to insufficient lubrication or clearance. Correct the assembly condition before fitting the replacement.
Receiving and Installation Controls
Compare the supplied part number and packing label with the approved reference.
Check both faces and every interface against the removed disc.
Verify quantity and whether it is an individual part or set.
Keep the recorded stack order and orientation.
Use verified clearance, lubrication and tightening procedures.
Perform a controlled initial run and monitor noise, heat, engagement and leakage.
Related XCMG Loader References
Cross-checking may include the disc ZL40A.30.5-34, the disc ZL40A.30.5.1 and the flange ZL40A.30. Similar numbering may locate an assembly family but does not prove interchangeability.
Frequently Asked Questions
Are ZL40.A.30.1 and ZL40.A.30 the same part?
This page cannot confirm that. Provide the marking and drawing position.
Does punctuation matter?
It can. Preserve the original punctuation and compare dimensions and interfaces.
Can the loader model confirm fitment?
Also confirm machine serial, assembly reference, item position and geometry.
Is the disc supplied alone or as a set?
The supply scope is not stated. Request an itemized quotation.
Quotation checklist: send both references, exact marking, model and serial, parts drawing, both faces, dimensions and quantity.
