Why the Same Part Number Ships in Multiple Variants

A single base number can mask real differences in spring preload and mounting geometry.

I started out tearing down compactors in a Guangzhou repair shop, and one mistake still sticks with me. We ordered a recoil starter for a Multiquip MTX60 based on the tag number alone. The outer diameter and mounting holes lined up, but the return spring hook angle was off by just enough to bind the pull rope after three or four starts. The machine sat dead while we waited on a replacement. That experience drives how I approach every cross-reference now. When a buyer sends me a request for Recoil Starter 28400Z0DV04ZA, I pull the MTX70 variant records, compare the spring anchor geometry, and check the rope pulley groove depth before confirming the fit [NEED_CITE: aftermarket small engine starter variant identification practices]. Cross-reference tables get copied between sellers without verification, so one transposed digit in the reference chain can send you a starter that physically bolts on but will not cycle reliably.

Fitment Coverage Across the MTX Line and GX100 Platform

This Recoil Starter 28400Z0DV04ZA is documented as compatible with Multiquip MTX60, MTX70, and MTX70HD rammers, as well as the Mikasa-badged equivalents sharing the Honda GX100 engine. The GX100 is a common single-cylinder platform, so the starter must match both the engine flywheel cup profile and the compactor frame cutout that routes the pull handle. I verify each variant by cross-referencing the housing bolt circle diameter and the starter cup engagement depth against the specific machine serial range.

Critical Interface Points Before You Commit to a Bulk Order

The housing mounting flange must align with the GX100 blower cover bolt pattern—typically three or four bolts depending on production year. The rope anchor and pulley groove machining tolerance is held to ±0.05 mm, which matters because even slight deviation causes the rope to stack unevenly and jam under repeated pulls. The return spring hook angle must match the flywheel cup slot geometry. I always recommend a single-piece sample for physical trial fitment before releasing a larger order [NEED_CITE: small engine recoil starter installation verification procedures]. The rubber grommets meet SAE J2044 oil-resistance standards, which is important on compactor frames where hydraulic fluid and fuel contact is routine.

What the Material and Treatment Specs Mean on a Rammer Frame

The A380 die-cast aluminum housing provides a balance of rigidity and weight appropriate for the vibration environment of a soil compactor. ASTM A228 music wire for the internal spring delivers consistent rebound force across the rated 48–52 HRC hardness range, resisting fatigue over hundreds of pull cycles. The chromate conversion coating per MIL-DTL-5541 Class 1A protects against corrosion in the wet, muddy conditions typical of trench backfilling and road base work. Rebound performance is tested to ISO 8535-1, which defines acceptable retraction behavior for small engine starters.

What Happens When the Wrong Variant Goes on the Machine

A starter that bolts on but has the wrong spring hook angle will pull fine once or twice, then the rope fails to retract fully and the operator yanks it again at an awkward angle. The rope frays at the pulley lip, and within a week you have a machine that will not start on site. On a compaction job, that delays backfill sign-off and holds up the next trade. Return shipping of a batch of misidentified starters costs more than the parts themselves once freight and idle crew time are factored in [NEED_CITE: equipment downtime cost impact on earthwork subcontractors].

Why Buyers Source This Part Through XUNPO

Our own production on selected lines and qualified sourced supply both carry the same quality control and warranty terms, so there is no guesswork about which batch you received. Eight product categories mean you can add air filters, fuel lines, and seal kits for the GX100 to the same order as this recoil starter. Minimum order is one piece, so a single emergency replacement ships without waiting to bundle. Our Guangzhou warehouse stocks common fast-failure items for rapid dispatch. We identify parts from a part number, machine model, photograph, or even a painted-over nameplate image. Cross-reference verification covers superseded numbers like 28400-Z0D-V04Z, and we supply a sample for fitment confirmation before you commit to bulk quantities. The technical team confirms compatibility and grade against your specific machine serial number.

Documentation & Verification

• Commercial invoice listing 28400Z0DV04ZA with machine model compatibility noted
• Part compatibility and cross-reference sheet marking 28400-Z0D-V04ZA and 28400-Z0D-V04Z as reference only
• Dimensional inspection record covering housing bolt pattern and pulley groove tolerance
• Warranty terms document specifying coverage period for manufacturing defects
• Packing photographs showing recoil starter units secured against shipping vibration
• HS code classification support for customs clearance in destination country

Fitment Check Before Installation

• Compare housing bolt circle diameter on the new unit against the removed starter or GX100 blower cover pattern
• Verify pull rope exit direction matches the frame shroud cutout on your specific MTX variant
• Check return spring hook engagement by manually cycling the pulley before bolting the housing to the engine
• Confirm rope length and handle type match the original to avoid interference with the compactor frame
• If any dimension does not match, stop and send photos for cross-reference re-verification

Tell Us What You Need Verified

Send the exact machine model and serial number, a photo of the old starter label if readable, and any visible damage to the housing or rope assembly. If the nameplate is gone, a photo of the engine flywheel area and the mounting bolt pattern is enough for our team to confirm fitment and cross-reference the correct variant for your compactor.

Frequently Asked Questions

Q: How do I confirm Recoil Starter 28400Z0DV04ZA fits my MTX70HD specifically? A: Provide the full machine serial number so we can cross-check the production date against the GX100 engine variant installed. The MTX70HD uses the same base starter but may have frame shroud differences affecting rope routing. We verify bolt pattern and exit orientation before confirming fitment.

Q: My old part is labeled 28400-Z0D-V04Z without the final A—can I use this replacement? A: The shortened number 28400-Z0D-V04Z is a recognized cross-reference (reference only) that typically indicates an earlier production marking or simplified label. We confirm interchangeability by matching the physical dimensions and spring geometry rather than relying solely on the label text.

Q: Why does the same base part number appear in different configurations? A: Production revisions across MTX60, MTX70, and MTX70HD may adjust the spring preload or housing detail while retaining the base number. We verify each variant against your specific machine serial range to ensure the spring hook angle and pulley depth match your engine flywheel cup.

Q: I only have the MTX60 model, no readable part number on the old starter—what next? A: Send a photograph of the engine area showing the blower housing bolt pattern and the rope exit position. Our team uses the machine model and visual details to confirm the correct recoil starter variant, including checking for any mid-production changes on the GX100 platform.

Q: Can I get a single sample to test fit before ordering a batch? A: Yes, our minimum order is one piece. We ship a single unit for you to physically install and confirm housing alignment, spring engagement, and rope retraction before you release a larger order quantity. This eliminates the risk of batch fitment failures on site.
