MH000184, MH 000184 BOLT MITSUBISHI , heavy-duty fastener for Mitsubishi powertrains

The MH000184 BOLT MITSUBISHI is a high-strength fastener engineered for demanding Mitsubishi heavy machinery and large engine assemblies. Built to hold under heat, vibration and torsional loads, this long shank, partially threaded hex bolt is used in drivetrain and generator applications where clamp force integrity is critical over thousands of service hours.

Independent parts lists show MH000184 specified inside the Mitsubishi MG430 motor grader transmission assembly, and also in documentation for Mitsubishi S-series generator sets built around the S16R industrial engine.

Why this MH000184 bolt matters in your machine

Heavy equipment relies on controlled preload in critical joints. The MH000184 bolt provides:

• High tensile capacity and elongation to maintain clamp load under shock.

• A long, smooth shank to accurately locate housings/bushings while the threaded end provides secure tightening.

• Consistent metallurgy and heat treatment for repeatable torque-to-tension characteristics.

• Corrosion-resistant, phosphate-black finish to improve run-in and reduce galling during installation.

For owners and fleet managers, that translates into fewer loosening events, longer service intervals and reliable uptime.

Verified applications & model coverage

Cross-referenced service literature and illustrated parts lists show MH000184 used in the following Mitsubishi platforms (exact position varies by assembly):

Motor graders

• Mitsubishi MG430 – transmission group listings include “MH000184 BOLT (qty 10)” in the drivetrain parts chart.

Generator sets / industrial engines

• Mitsubishi S16R (e.g., S16R-PTA/-STA series) generator packages – parts catalogs for S16R generator units include the part code in hardware groupings for engine/genset assembly.

Tip: these engines also appear in stationary power modules and large construction equipment. If you’re matching MH000184 by machine serial number, share your S/N and arrangement number and our parts team will double-confirm fit before shipping.

Key features of the MH000184 bolt

Engineered clamp force

The MH000184 BOLT MITSUBISHI is designed for high joint reliability. The long unthreaded portion helps carry shear across mating components, typical in gearcase housings and carrier mounts, while the rolled threads deliver superior root strength when torqued to spec.

Dimensional consistency

Every lot is manufactured to tight tolerance for shank diameter, thread pitch and under-head radius. This ensures repeatable torque figures across multiple fasteners in the same joint so clamp load is balanced around circular housings (e.g., carrier plates, end bells and mounting flanges).

Surface protection

A black phosphate or similar anti-corrosion treatment (as commonly used on drivetrain bolts) improves initial run-in, resists fretting and allows accurate torque thanks to controlled friction at the bearing surfaces.

Built for serviceability

The hex head is sized for standard shop tools. With the correct torque and thread preparation (clean, lightly oiled unless otherwise specified), removal and re-torque at overhaul is straightforward.

---

Typical use cases in the field

• Transmission & planetary gear carriers (MG430) – securing carriers, plates and housings where balanced clamp around a circular flange is essential.

• Generator set structural joints (S16R gensets) – fastening engine to baseframe adapters, accessory brackets or end-bell/stator housings, where sustained vibration demands a high-strength fastener.

Technical details & specifications

While fastener dimensions may vary by revision, the following specifications describe the MH000184 category of hardware used in Mitsubishi heavy machinery:

• Part code: MH000184 (also written MH 000184)

• Type: Hex-head bolt, partial thread (long plain shank)

• Material class: High-tensile alloy steel, heat-treated

• Finish: Phosphate/black oxide style protective coating (installation-friendly)

• Thread standard: Metric, rolled (contact us for pitch confirmation against your serial number)

• Recommended use: Transmission carriers, housings, engine/generator mounting points, heavy brackets

• Torque guidance: Follow machine/engine manual torque chart for MH000184 at the specific thread size and lubrication state

• Net weight (per unit): ≈0.18 kg (typical shipping weight for an M12–M14 x long shank bolt used in these assemblies; request exact mass by revision)

Always torque in the sequence specified by the workshop manual. For circular flanges (planetaries, end bells), use a star or criss-cross pattern, increasing in stages to final torque.

Installation best practices

1) Identify and prep the joint

Confirm the hole size and grip length. Clean threads with a chaser, not a tap, to retain class fit. Verify mating faces are flat and oil-free unless the manual calls for a light oil film.

2) Choose the right thread conditioner

Unless otherwise specified, use clean engine oil or a torque-approved assembly lube. Never mix lubricated and dry bolts in the same joint; it skews clamp force.

3) Stage torque

Bring the joint to 30%, 60%, then 100% of final torque, following the criss-cross pattern. Mark heads for torque-check paint lines to detect movement in service.

4) Re-torque at first service

On transmissions and generators subject to thermal cycling, re-check torque after initial warm-up hours if your service manual advises it.

Frequently asked questions

Is MH000184 the same as “MH 000184”?

Yes, the space is simply a formatting variation used in different catalogs. The underlying part code is the same.

Can I replace only one bolt?

In safety-critical or circular flange joints, we recommend replacing the full set so clamp force is balanced. At minimum, replace any bolt with thread damage or visible necking.

Do I need new washers or locking elements?

Where the parts list calls for spring or plain washers, it’s best practice to renew them with the bolt set. (Many MG430 diagrams list associated washers alongside MH000184.)
