HeavyEQ parts intelligence

John Deere substitutes and installed-assembly research

Research first. Identify the installed component. Confirm the application.

Parts for sale Request a part Sell parts

A Deere storefront substitute is a source-attributed relationship. It remains separate from a serial-specific application, an installation approval and the actual item offered for sale. Preserve both identifiers and the limits of the source before asking for a quote.

Read a substitute without turning it into universal supersession

The US Deere source for final fuel filter MIU802154 lists MIU805005 as a substitute. That statement is useful, but it does not specify every engine build, serial interval or later service modification. Keep the direction MIU802154 to the listed substitute and attribute it to the exact source. Do not infer the reverse relationship or extend it through another part’s substitute list. Regional pages can differ; HeavyEQ has not combined dimensions or model lists from different storefront markets into one universal record.

Separate the component from the carrier

An excavator boom, boom kit, seal kit, seat swivel kit, sensor and bucket attachment are different item classes. A boom kit label does not establish kit contents, load capacity, pin geometry or a safe installation. A seal kit needs the exact assembly identification and revision. A bucket needs documented attachment geometry and application limits. The identifiers below provide a starting point for finding the correct documentation; they are not maintenance procedures or technical approval to install a structural or hydraulic component.

PIN filtering has a scope

Deere describes catalogue, section and individual-part levels of PIN filtering. Preserve the level that was actually returned and compare the installed assembly with the intended factory configuration. Dealer alterations and later repairs can change what is on the machine. A model-only list remains general even if an exact part number appears beside it. Full machine identification belongs in a controlled service exchange; keep full PINs out of public descriptions, photographs and URLs.

Resolve a source conflict before promising application

The supplied research associated bucket BYT10959 with 35G. The reviewed US and Canadian source lists did not support that association, so HeavyEQ has withheld it. That does not establish an explicit incompatibility; it identifies an evidence gap. Ask for a separately authoritative application record before making either claim. A buyer can still submit an identification request using the exact bucket reference and the installed attachment details without receiving a false fitment result.

Reviewed item references and identification questions

Exact issuer identities are separate from machine applications and seller inventory. Each reference has its own source and unresolved technical questions. No source application table, stock, pricing or third-party media is reproduced.

John Deere 4343427: Filter

Deere identifies a filter using this exact number. The general storefront category does not establish the filter circuit or a serial-specific installation.

Identify the circuit and installed filter housing before treating this general filter label as a selection. The item identity does not establish a service interval, media specification or equivalent item.

John Deere 7049713G: Excavator boom kit

Deere identifies a boom kit. A kit reference should remain distinct from an individual boom or its constituent structural items until documentation resolves the supplied scope.

Identify the actual boom assembly, revision and applicable machine configuration. A boom or kit title does not establish pin geometry, structural capacity, complete kit content or approval to install.

John Deere AT437909: Excavator tilt seat swivel kit

Deere identifies a seat tilt/swivel assembly kit. General equipment labels do not establish the cab options, mounting arrangement or installation procedure on a particular excavator.

Identify the installed seat and cab configuration, connections and approved assembly documentation. A swivel-kit identity does not establish installation approval or safety-system compatibility.

John Deere FYD60002054: Excavator boom

Deere identifies an excavator boom. The listed model is a starting point for structural documentation, not approval for a repair or donor-component swap.

Identify the actual boom assembly, revision and applicable machine configuration. A boom or kit title does not establish pin geometry, structural capacity, complete kit content or approval to install.

John Deere 1J16B001B3: Excavator boom

Deere identifies an excavator boom and presents a boom kit as a substitute. Preserve that direction and item-type difference; require an equipment-specific check before recommending substitution.

Identify the actual boom assembly, revision and applicable machine configuration. A boom or kit title does not establish pin geometry, structural capacity, complete kit content or approval to install.

John Deere FYA00007744: Excavator seal kit

Deere identifies an excavator seal kit. The component assembly and its revision must be resolved separately from the general excavator model list.

Identify the exact motor or cylinder assembly and revision before interpreting a seal-kit reference. A kit label does not establish contents or compatibility with every assembly in a machine family.

John Deere MIU802154: Final fuel filter

Deere identifies a final fuel filter and separately lists a substitute. Record both identifiers and the direction of the store reference without promising that either fits every listed model.

Identify the installed fuel system and housing before selection. A filter reference or comparison-panel placement does not establish equivalent performance, replacement direction or a machine application.

John Deere 8976879440: Fuel injection nozzle

Deere identifies a fuel injection nozzle. A listed replacement candidate does not resolve injector calibration, engine build or the machine-specific service procedure.

Identify the installed engine, injector arrangement and applicable calibration documentation. A source-listed nozzle or substitute does not establish a safe interchange across engine revisions.

John Deere 4444902: Excavator angle sensor

Deere identifies an angle sensor and lists another sensor as a substitute. Confirm the installed hydraulic/control arrangement and connector identity before selecting a replacement.

Record the installed sensor position, connector and documented control-system revision. An angle-sensor number does not establish signal characteristics, calibration or compatibility by model name alone.

John Deere AT473966: Excavator boom

Deere identifies an excavator boom with a substitute listed. Preserve the structural part identities separately and obtain the relevant machine configuration and technical approval.

Identify the actual boom assembly, revision and applicable machine configuration. A boom or kit title does not establish pin geometry, structural capacity, complete kit content or approval to install.

John Deere BYT10959: 12-inch heavy-duty excavator bucket

Deere identifies a twelve-inch excavator bucket and lists another bucket as a substitute. Attachment geometry, coupler arrangement and machine capacity still need independent confirmation.

Verify the installed attachment interface and documented machine application. A bucket reference does not establish pin spacing, linkage, capacity or an application absent from the source evidence.
