Why the Same Reference Number Ships Across Multiple Dynapac Generations

A Shock Absorber Rubber Vibration Mount for Dynapac CA51 CA610 CA702 may share a reference number while differing in mounting insert geometry between production years.

In the Pearl River Delta region, I have seen Dynapac CA51 through CA702 cushion dampers arrive on site only to reveal bolt hole misalignment caused by a batch variant the catalog did not flag. Worn or painted-over nameplates make it nearly impossible to confirm whether 358172 or 4700358172 (cross-reference only for identification purposes) applies to a specific machine build. A mismatched mount forces the roller to sit idle while a replacement is sourced — [NEED_CITE: aftermarket part variant tracking across equipment production years].

Machine Model and Serial Range Coverage

This Cushion Damper spans the full Dynapac CA-series from the CA51 through the CA702, plus SCA512 and SCA610 variants. Fitment depends not just on model designation but on the production serial range, which determines whether the mounting insert pattern and bolt circle match your chassis drillings. Our technical team verifies serial prefix data to confirm which reference applies before any Shock Absorber Rubber Vibration Mount for Dynapac CA51 CA610 CA702 ships.

Mounting Interface and Insert Pattern Verification

The steel mounting inserts are zinc-plated to ISO 4042 and positioned to match factory chassis hole patterns. Mounting hole tolerance is held tight to prevent installation misalignment on compaction equipment that operates under continuous high-frequency vibration. Before bulk commitment, buyers can request a sample unit to physically check bolt alignment, insert depth, and rubber-to-frame clearance on the actual machine — [NEED_CITE: vibration isolation mount interface verification standards for construction equipment].

Decoding the Specification Sheet

The high-damping natural rubber compound is formulated to absorb the specific vibration frequencies generated by Dynapac CA-series eccentric drum mechanisms. Operating temperature range from -20°C to +70°C covers most construction environments from cold-season road rehabilitation to hot-climate landfill compaction. The steel insert surface treatment to ISO 4042 provides corrosion resistance during storage and in humid or saline job-site conditions. These parameters together determine whether the Cushion Damper maintains isolation performance under sustained dynamic loading without premature rubber degradation or insert loosening.

The Hidden Cost of a Mount That Almost Fits

A Cushion Damper that bolts on with minor force may appear installed correctly but introduces uneven load distribution across the rubber body. On vibratory rollers operating thousands of cycles daily, this off-axis loading accelerates rubber fatigue and can transmit uncontrolled vibration into the engine bay and operator cabin. The result is not immediate failure but a gradual increase in cabin noise, accelerated wear on adjacent fasteners, and eventually a cracked mounting bracket — [NEED_CITE: vibration transmission effects from degraded isolation mounts on compaction equipment].

Why Source This Part Through Our Operation

Selected part lines are produced in our own facility, with remaining supply sourced from qualified ISO-certified manufacturing partners — both carry identical QC and warranty terms. Eight product categories sit under one account, so this Shock Absorber Rubber Vibration Mount for Dynapac CA51 CA610 CA702 can ship alongside engine gaskets, hydraulic seals, and undercarriage components in a single consignment. Minimum order is one piece, allowing emergency single-unit procurement without waiting to build a larger order. Cross-reference verification between 358172 and 4700358172 covers superseded and alternate numbers. A sample unit is available for physical fitment confirmation before fleet-wide commitment.

Documentation & Verification

• Commercial invoice and packing list with part number 358172 or 4700358172 and machine model listed
• Cross-reference sheet confirming 358172 and 4700358172 applicability per serial range (reference only)
• Dimensional inspection record covering mounting hole spacing and insert position tolerance
• Six-month warranty terms against manufacturing defects included with every shipment
• Packing photographs taken before crate closure for visual dispatch confirmation
• HS code and customs documentation support provided for international clearance

Fitment Check Before Installation

• Compare mounting hole spacing on the new Cushion Damper against the removed original before installation
• Verify bolt length and thread engagement depth match the steel insert specifications
• Check rubber-to-chassis clearance to ensure no contact under static compression load
• Confirm part number applicability against machine serial prefix if nameplate is unreadable
• Run the roller at low vibration amplitude first and inspect mount seating after initial operation

Requesting a Fitment Confirmation

Send the machine model, serial number prefix, and photographs of the existing mount including the mounting face and any readable markings. If the nameplate is gone, a photo of the chassis mounting area and the old damper's insert pattern is enough for our technical team to verify whether 358172 or 4700358172 is the correct reference for your specific Dynapac CA-series build.

Frequently Asked Questions

Q: How do I confirm this mount fits my specific Dynapac CA-series model and serial range? A: Provide the machine model and serial prefix to our technical team. We cross-check production records to verify whether 358172 or 4700358172 (reference only) applies to your specific build. Serial range confirmation ensures the mounting insert pattern and bolt circle match your chassis drillings before the Cushion Damper ships.

Q: What is the difference between reference numbers 358172 and 4700358172 — are they interchangeable? A: These numbers may refer to different production batches or revised mounting configurations across Dynapac CA-series generations. They are not universally interchangeable. Our team verifies which reference matches your machine's serial range to prevent fitment issues on arrival.

Q: My machine nameplate is worn or unreadable — can I order using only the machine model? A: Machine model alone narrows the options but may not resolve variant differences. Photographs of the old Cushion Damper, particularly the steel insert pattern and mounting face dimensions, allow our team to confirm the correct Shock Absorber Rubber Vibration Mount for Dynapac CA51 CA610 CA702 without relying on a nameplate.

Q: Can I get a sample to verify fitment before committing to a larger order? A: Yes. A sample unit ships with the same QC and warranty terms as bulk supply. Install it on one machine to confirm bolt alignment, rubber clearance, and vibration isolation performance before committing to fleet-wide replacement orders across your Dynapac CA-series rollers.

Q: Are there variant differences in this mount across different CA-series production years? A: Yes. Mounting insert geometry and bolt circle dimensions can vary between production years even when the machine model designation remains unchanged. Serial prefix verification is the reliable method to identify which variant applies to your specific Dynapac roller.
