Why the Same Part Number Arrives in Multiple Variants

The correct Shock Absorber Rubber Vibration Mount for Dynapac CA510 CA610 depends on machine serial range, not just the base number.

Cross-reference tables circulated online frequently lump 358172 and 4700358172 together as interchangeable. They are not always direct swaps. A CA510 from an early production run may specify a different rubber hardness grade than a later CA612, even though both machines list the same base identifier in parts catalogues [NEED_CITE: Dynapac CA series vibratory roller engine mount specification variants]. When the durometer is wrong, the damper transmits rather than absorbs vibration, loosening fasteners across the engine bay within weeks. I have seen this happen on a CA510 where a copied cross-reference led to the wrong variant being fitted, and the resulting vibration caused secondary failures on adjacent hose connections.

Fitment Range Across the Dynapac CA and SCA Families

This cushion damper covers a wide span of Dynapac rollers from the CA51 through the CA702, plus SCA soil compactor variants. The key is matching the specific production batch to the correct mount geometry. Earlier CA51 and CA510 units often carry the 358172 marking, while later CA610 and CA612 machines may reference 4700358172 as a superseded number. Neither number alone guarantees a fit without serial-range confirmation. When a nameplate is worn or painted over, the machine model combined with build-year narrows the variant field substantially.

Interface and Dimensional Verification

Bolt pattern spacing, mount height, and metal core geometry must match the existing installation precisely. Even a few millimetres of deviation in hole centre-to-centre distance prevents proper seating and induces shear stress on the fasteners. The rubber-to-metal bond interface on this Shock Absorber Rubber Vibration Mount is designed to replicate the load distribution of the factory-specified component [NEED_CITE: elastomeric vibration isolator bonding standards for heavy compaction equipment]. Before bulk ordering, request a sample and physically trial-fit it against the mounting bracket to confirm alignment, rubber clearance, and fastener engagement depth.

Reading the Material and Hardness Specifications

The precision-molded rubber compound is formulated to withstand continuous vibratory loading typical of road compaction work. Rubber durometer directly governs how much engine vibration transfers into the chassis — too soft and the engine shifts under load, too hard and high-frequency vibration bypasses the mount entirely. The corrosion-resistant metal core resists moisture ingress common on construction sites and during pressure washing. For machines operating on highway construction or airport runway projects where sustained high-amplitude compaction is standard, the hardness grade must align with the vibration class the roller produces [NEED_CITE: vibration isolation requirements for self-propelled road rollers].

What Happens When the Wrong Variant Gets Installed

An incorrectly matched cushion damper does not fail quietly. The rubber may appear intact while the metal core shifts under load, producing a knocking sound that mechanics often misdiagnose as an engine internal issue. In other cases, the rubber compound tears at the bond line within a few hundred operating hours because the durometer was specified for a lighter machine class. The downstream cost is not just the replacement mount — it includes the diagnostic time spent chasing phantom engine faults and the compaction quality issues that arise when the drum vibration pattern is inconsistent [NEED_CITE: effects of engine mount degradation on vibratory roller compaction uniformity].

Why Buyers Source This Part Here

We produce selected part lines in our own facility and source the remainder from qualified ISO-certified partners, so both carry the same QC and warranty terms. For the 358172 and 4700358172 range, cross-reference verification covers superseded and alternate numbers across Dynapac roller generations. A single piece ships when one machine is down and you need an emergency replacement. Guangzhou warehouse stock enables fast dispatch on common variants. Our technical team confirms compatibility by machine model, serial number, or photograph of the existing mount, and sample supply is available before you commit to a full fleet order.

Documentation & Verification

• Commercial invoice listing both 358172 and 4700358172 with applicable HS codes
• Part compatibility sheet mapping machine serial ranges to correct mount variant (reference only)
• Dimensional inspection record covering bolt spacing, mount height, and rubber durometer
• Warranty terms covering manufacturing defects for 3 to 12 months
• Packing photographs showing cushion damper condition before crate closure
• Customs documentation support with correct classification for rubber-metal vibration mounts

Fitment Check Before Installation

• Measure bolt centre-to-centre distance on the existing bracket before unboxing the new mount
• Compare rubber hardness feel and metal core shape against the removed component
• Trial-fit the Shock Absorber Rubber Vibration Mount without fully torquing fasteners to verify alignment
• Check clearance between the mount and adjacent engine components at full compression travel
• If the bolt pattern does not align, stop installation and contact us with photos for variant re-verification

Confirm Your Fitment Before Ordering

Send the machine model and serial number, or a photograph of the existing mount and its markings if readable. If the nameplate is gone, a photo of the engine mounting bracket and the general engine layout helps narrow the correct variant. We will cross-reference 358172 and 4700358172 against your specific Dynapac CA or SCA roller and confirm which version fits before any commitment.

Frequently Asked Questions

Q: How do I confirm which mount fits my specific Dynapac CA or SCA machine? A: Provide the machine model and serial number. We cross-reference your build record against the 358172 and 4700358172 compatibility table to identify the correct variant, including rubber durometer grade and metal core geometry. If the nameplate is unreadable, a photograph of the existing mount or the engine bracket helps us narrow the match.

Q: Are 358172 and 4700358172 interchangeable, or are they different variants? A: They are not always direct swaps. While both serve as cushion dampers across the Dynapac CA and SCA range, they may differ in rubber hardness or metal core dimensions depending on machine generation. We verify each number against your specific serial range to confirm whether one supersedes the other on your roller.

Q: What if I only have the machine model and no readable part number? A: The machine model combined with approximate build year is usually enough to identify the correct variant. Send us a photograph of the engine mounting area or the old mount, even if markings are worn or painted over. Our technical team uses visual reference alongside production records to confirm the right Shock Absorber Rubber Vibration Mount for your unit.

Q: Can I get a sample to test fitment before committing to a full order? A: Yes. Sample supply is available for physical fitment confirmation on site. Install the sample on one machine, verify bolt alignment, rubber clearance, and vibration behaviour under load, then proceed with the full order once the correct variant is confirmed across your fleet.

Q: Will this mount fit older Dynapac rollers whose original numbers have been superseded? A: Cross-reference validation covers superseded and alternate part numbers across Dynapac roller generations. Many older CA and SCA machines have had their original mount numbers replaced by updated identifiers. We trace the supersession chain to confirm whether 358172 or 4700358172 is the current valid reference for your specific machine serial number.
