Multiquip Mikasa 8511S — Genuine OEM 11" Wood Shoe Kit for MTX70HD, MTX70HDR, MTX70HF & MTX80HDR Tamping Rammers

The shoe is the only part of a tamping rammer that touches the ground. On a Multiquip MTX-Series rammer running at full RPM, the foot strikes the substrate 644 to 695 times every minute — roughly 310,000 to 334,000 ground impacts in a single 8-hour shift. The laminated wood shoe absorbs every one of those impacts, and over time it cracks, splits, separates from its tempered-steel base plate, and walks the mounting bolts loose.

Multiquip part 8511S is the genuine OEM 11-inch wood shoe kit that returns your rammer to factory-spec compaction performance. The kit fits the entire 11-inch-shoe MTX-Series lineup — MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR — and ships complete with the laminated wood pad, the tempered steel base plate, and all the mounting hardware needed for installation.

Why genuine OEM matters on a wear part this critical

A worn or undersized aftermarket shoe doesn't fail in isolation — it transmits asymmetric impact loads upward into the bellows (368346180), the main spring (368461270), and the spring cylinder (368347281) above it. Operators who run a degraded shoe past its replacement window typically end up replacing two or three additional components within six months. The 8511S kit is engineered to the same factory specification as the shoe that shipped on your rammer when it left Multiquip's production line — same wood lamination grade, same steel plate temper, same bolt-hole tolerance.

DanseUSA has been an authorized Multiquip parts dealer since 1981. Every 8511S ships in original Multiquip packaging through authorized supply channels, with full OEM warranty eligibility on the part.

What's in the 8511S Kit

The 8511S is a complete shoe-replacement bundle, not a stand-alone wood pad. The OEM kit ships with everything needed to bolt a new shoe to the foot housing in a single transaction:

Per Multiquip's MTX-Series Operation Manual, the foot construction is described as "laminated wood with tempered steel plate for superior shock absorption." The two-layer engineering protects the rest of the rammer from sharp impulse loads — the wood absorbs, the steel transmits, and the rammer's spring/bellows system above the foot operates within its designed loading envelope.

Legacy part-number cross-reference: The 8511S supersedes Multiquip part numbers 366910020 and 362910130. If your service records, parts manual, or fleet inventory references either older number, the 8511S is the direct factory replacement.

Multi-Model Compatibility Table

The 11-inch wood shoe is shared across the entire MTX70/MTX80 platform regardless of engine package or impact rating. The same physical 8511S kit fits all four models confirmed in Multiquip's parts manual lookup:

Shoe footprint across all four models: 11.2 × 13.4 in (285 × 340 mm). Mounting bolt pattern, hardware grade, and base plate geometry are identical.

Important — what 8511S does NOT fit: The 8511S is for the 11-inch-shoe platform only. It does not fit smaller MTX rammers — specifically the MTX50HD and MTX60HD, which use a 10.4-inch shoe (foot assembly 362910150) with a different mounting footprint. If you're servicing an MTX50HD or MTX60HD, you need a different shoe kit; contact us for the correct part number.

Failure Modes — When to Replace the Shoe

Multiquip's MTX-Series Operation Manual lists shoe inspection under daily preventive maintenance. The shoe is treated as a scheduled-replacement consumable, not a run-to-failure component. The field signals indicating immediate replacement:

• Visible cracks running across the wood face, especially around the bolt holes
• Lamination separation — the wood layers begin to delaminate and air gaps appear at the edges
• Mushroomed or recessed bolt heads — impact loading has deformed the hardware
• Asphalt or aggregate embedded in the wood face causing imbalance or surface contamination
• Uneven wear pattern across the face indicating asymmetric impact distribution
• Audible change in the rammer's compaction note — a worn shoe sounds different than a fresh one

Replacement intervals vary by application and machine. As a working baseline:

Installation Pointers (Universal)

The 8511S installs on all four compatible models using the same procedure. Steps that materially affect install quality:

1. Shut down and allow the foot housing to cool before disassembly. The muffler heat-soaks adjacent components during operation.
2. Photograph the existing bolt arrangement before removing the worn shoe. The square-neck bolts seat in specific orientations on the steel plate, and reproducing the pattern from memory wastes bench time.
3. Inspect the foot housing mating surface for impact damage from the failed shoe. If you see scoring, gouging, or hairline cracks in the housing itself, address that before installing the new shoe — running a fresh shoe against a damaged housing causes premature replacement.
4. Use the OEM hardware that ships with the 8511S kit. The square-neck bolts are graded for impact loading. Substituting hardware-store bolts is the most common field cause of premature shoe-bolt loosening.
5. Torque the new hardware in a cross-pattern sequence, not sequentially around the perimeter. Cross-pattern torquing creates even preload distribution across the bolt joint.
6. Re-torque after the first 30 minutes of run time, again at 4 hours, and once more at the 24-hour mark. Bolt preload migrates during the first day of operation under impact loading; after that, the joint is settled.
7. Bench-verify the rammer's idle-to-full-RPM transition before sending the unit back into service. A shoe-replacement that introduces installation issues sometimes shows up as RPM hunting under load.

Frequently Asked Questions

Q: Will the 8511S fit my specific Multiquip rammer? The 8511S fits all current 11-inch-shoe MTX-Series rammers — MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR. The same kit also fits legacy MTX70, MTX80, and MTX90 units (the 11-inch shoe platform predates the HD designation). If your serial plate confirms any of those models, this is the correct part. For MTX50HD or MTX60HD (10.4-inch shoe), this is the wrong part — contact us for the correct kit.

Q: Is the 8511S the same as 366910020 and 362910130? Yes. Multiquip consolidated the legacy part numbers 366910020 and 362910130 into the current 8511S SKU. All three numbers reference the same physical wood shoe kit. If your old parts manual or service records cite either older number, the 8511S is the direct supersession.

Q: Does the kit come with bolts, washers, and nuts? Yes. The OEM 8511S ships with all mounting hardware required for installation — square-neck bolts, lock washers, and nylon lock nuts. No separate hardware purchase is needed.

Q: How is the wood shoe constructed? Per Multiquip's Operation Manual, the foot construction is "laminated wood with tempered steel plate for superior shock absorption." The wood pad is a multi-ply laminate engineered to absorb impact progressively rather than transmitting a sharp impulse to the bellows and spring components above. The steel plate provides the structural interface to the rammer foot housing.

Q: How often should I replace the wood shoe? Replacement intervals depend on impact rating, run hours, and substrate hardness. For typical commercial use: MTX70HD every 6–12 months, MTX70HDR every 5–9 months, MTX70HF every 9–14 months, MTX80HDR every 4–9 months. Inspect daily and replace at the first sign of cracking, lamination separation, or bolt-head deformation.

Q: What's the difference between an OEM 8511S and aftermarket 11-inch shoes from Amazon or eBay? Aftermarket 11-inch shoes are dimensionally similar to the OEM 8511S but vary widely in wood lamination grade, steel plate temper, and bolt-hole tolerance. The 8511S is manufactured to factory specification and is compatible with Multiquip's warranty terms. For commercial-fleet operators where downtime cost outweighs unit cost, OEM is typically the lower-total-cost option over the rammer's service life.

Q: Will replacing the shoe void my Multiquip warranty? No — replacing wear components like the shoe is normal preventive maintenance and does not affect warranty terms. Using the genuine OEM 8511S keeps the rammer in factory-spec configuration. If your unit is still under original warranty and you have questions about coverage, contact us with your purchase information.

Q: Can I install the 8511S myself, or do I need a Multiquip-authorized service center? Field installation is straightforward with basic hand tools. The kit ships with all required hardware. Most fleet mechanics complete the install in 30–60 minutes. Document the installation with photos if your unit is under warranty and the shoe failure was accompanied by other foot-assembly damage.

Q: How is the 8511S shipped? DanseUSA ships the 8511S in original Multiquip packaging via standard ground service. Some MTX-Series components may ship from Multiquip's distribution warehouse direct — when that happens, your order may arrive in separate packages with individual tracking numbers.

Q: Is the 8511S in stock right now? Stock status updates in real time on this product page. Most orders placed before noon ET ship the same business day. If a stock issue affects your order, we'll notify you before any charge is finalized.
