Three-Stage Long-Body Ejector Cylinder for 39/43-Yard Waste Bodies

The M-1489241 is a three-stage long-body ejector cylinder listed in the HCIC-2026 product catalog for an M 39/43 Yard Long Body Ejector Cylinder application. The catalog lists 182.56-inch stroke.

That is the complete model-specific information available in the catalog row. The PDF does not publish a model-specific bore, rod diameter, working pressure, port size, weight or closed length for M-1489241. Those values must be confirmed against the proposed waste body and hydraulic circuit before quotation or replacement approval.

The right way to evaluate this model is as part of a long-body ejector system. The cylinder, ejector plate, body guides, rear structure, mounting pins and hydraulic controls must all work through the same movement path.

I. M-1489241 Catalog Data

The missing fields are not a weakness in the article; they are an important purchasing boundary. A buyer should not copy values from another ejector cylinder simply because the stage count or application appears similar.

II. Why the Three-Stage Configuration Matters

A three-stage telescopic cylinder divides a long movement into nested sections. For a long-body ejector system, that arrangement can help the actuator deliver extended linear travel within the available body layout.

The 182.56-inch stroke is the catalog-listed cylinder travel. It should not be treated as the same thing as the distance the ejector plate moves through the body. The final plate travel also depends on mounting geometry, mechanical stops, guide clearance and the way the cylinder is connected to the ejector structure.

The nested sections create additional inspection points. The body designer or maintenance team must check the full extension path, not only the first-stage barrel. Clearance around every stage, hose routing, protection from waste material and access for cleaning should be reviewed before installation.

III. How M-1489241 Fits a Long-Body Ejector System

In a long-body waste application, the ejector cylinder provides linear hydraulic movement. The ejector plate transfers that movement to the waste load, while the body floor, side guides and structural members carry the reaction forces.

This division of responsibility matters during troubleshooting. If an ejector plate binds, the hydraulic cylinder may be exposed to abnormal resistance even when the cylinder itself is correctly selected. Uneven loading, damaged guides, packed material or a distorted body can change the force required to complete the stroke.

A cylinder model should therefore be checked against:

• Ejector-plate travel and end positions
• Long-body internal length and available mounting space
• Pin and clevis arrangement
• Cylinder angle through the complete movement
• Stage clearance when fully retracted and extender
• Guide alignment and plate support
• Hose protection from waste, abrasion and pinch points
• Mechanical stops and hydraulic end-of-travel control

The model number identifies the catalog application. The machine drawing confirms whether the proposed unit can physically operate in that application.

IV. Replacement Identification: What to Check First

A long-body ejector cylinder should not be ordered from a photograph alone. Begin with the model marking and then verify the complete installation.

4.1 Confirm the model identity

Record the identification marking, body application, stage count and catalog stroke. M-1489241 is listed as a three-stage model with a 182.56-inch stroke for the M 39/43 Yard Long Body Ejector Cylinder application.

4.2 Measure both end positions

Record the cylinder mounting centers with the ejector retracted and extended. If the existing cylinder is damaged, use the machine's fixed mounting points and the ejector-plate position rather than relying only on the failed cylinder's distorted dimensions.

4.3 Check the three-stage path

Inspect the nested sections for contact with the body, floor, guides, brackets, guards and hydraulic hoses. A long stroke does not compensate for an installation that allows stage interference.

4.4 Check the ejector plate and guides

Move the plate through the available travel where safe. Look for skew, binding, uneven guide wear, compacted waste or structural deformation. A replacement cylinder should not be used to hide a body-guiding problem.

4.5 Confirm the hydraulic circuit

Provide the schematic, pump information, valve arrangement, operating pressure, flow, hose sizes and port arrangement. The catalog row does not publish model-specific pressure or flow data for M-1489241.

4.6 Review the working environment

Long-body ejector equipment operates around dust, waste residue, moisture and impact. Confirm how the cylinder rod and stages are protected, cleaned and inspected during routine service. The protection plan belongs to the complete vehicle design, not only to the cylinder quotation.

V. What to Send for an M-1489241 Inquiry

Send the following information to HCIC:

• Existing cylinder identification marking and photographs
• Waste-body manufacturer and model
• Confirmation of the 39-yard or 43-yard body application
• Ejector-plate photographs or drawing
• Retracted and extended mounting-center measurements
• Pin, clevis, bracket and guide dimensions
• Three-stage clearance photographs
• Hydraulic schematic and valve information
• Operating pressure, flow and cycle requirements
• Hose routing and protection details
• Failure history, if this is a replacement request
• Quantity, destination and required delivery documentation

If the original cylinder is unavailable, provide the fixed machine dimensions and movement requirements. An image of a long telescopic cylinder is not enough to reconstruct unlisted model data.

VI. What the Catalog Does Not Establish

The PDF confirms the model number, three-stage configuration, 182.56-inch stroke and M 39/43 Yard Long Body Ejector Cylinder application. It does not establish a universal bore, rod diameter, pressure rating, flow requirement, weight, port size, service life or interchangeability with another three-stage cylinder.

Those values must be taken from the current technical drawing and confirmed against the machine. No pressure, force or speed claim is added here because the model row does not provide those figures.

VII. Conclusion

M-1489241 is a specific catalog option for a long-body waste ejector application: three stages, 182.56-inch stroke and an M 39/43 Yard Long Body Ejector Cylinder reference.

The model is worth reviewing when a long-body ejector system requires extended telescopic movement, but the purchasing decision should be based on the complete body drawing and hydraulic circuit. Send HCIC the machine dimensions and movement requirements before treating M-1489241 as a direct replacement.
