Why a Single Part Number Covers Four Machine Generations

Bobcat compact equipment shares a common starter platform across model transitions, but superseded reference numbers create false mismatches in aftermarket catalogs.

A worn nameplate on a 331 might show 228000-6920, while the same physical unit on a newer E35 carries NDAS228000-6921. Cross-reference tables copied between sellers often drop the older number, leading workshops to believe the part is discontinued when it is simply relabeled [NEED_CITE: Bobcat compact excavator electrical system parts supersession]. I have traced starter motors through three numbering generations across the 325-to-E55 range, and the Starter Motor 6670727 remains the common denominator when you verify the physical dimensions rather than trusting a single catalog line.

Fitment Verification Across the Bobcat Compact Range

The Starter Motor 6670727 covers 18 Bobcat compact excavator models and the S100 skid steer loader, but model coverage alone does not guarantee a correct fit. Each machine variant may differ in terminal post position, mounting ear thickness, or solenoid clocking angle. We verify the specific serial range of your machine against our fitment database, checking that the 10T drive gear aligns with the flywheel ring gear and the CW rotation matches the engine cranking direction.

Physical Dimension Checks That Prevent Installation Surprises

The mounting bolt pattern on this starter must match the engine block pad exactly — a deviation of a few millimeters in hole spacing means the unit will not seat flush, creating misalignment between the drive gear and flywheel [NEED_CITE: starter motor alignment tolerance specifications for diesel engines]. Terminal post orientation determines whether the existing battery cable reaches without modification. We compare drive gear engagement depth against the flywheel housing specification for your specific Bobcat model, ensuring the pinion meshes correctly without binding or excessive backlash.

Decoding the Electrical Specifications for Field Conditions

The 12V system voltage aligns with the standard electrical architecture across Bobcat compact excavators and the S100 loader, where the alternator and battery are sized for this circuit. The 2.2KW power rating delivers sufficient cranking torque to turn over the diesel engine under cold-start conditions common on early-morning job sites. CW rotation is the correct direction for the Bobcat engine flywheel engagement; a reversed rotation starter would spin freely without engaging the ring gear. The 10-tooth drive gear matches the pitch and module of the flywheel ring gear fitted to these machines, ensuring smooth meshing without tooth skipping during cranking.

The Cost of Skipping a Fitment Check Before Ordering

An incorrect starter that arrives on site and fails to bolt on sends the machine back into downtime while a replacement is sourced — the original repair window is lost entirely. A unit that physically mounts but has the wrong drive gear engagement depth can cause tooth damage to the flywheel ring gear, turning a starter replacement into a flywheel removal [NEED_CITE: flywheel ring gear damage caused by starter misalignment]. Even a terminal orientation mismatch forces field modifications to cable routing, introducing vibration fatigue points that fail weeks later. These are not hypothetical risks on dusty quarry sites where machines cannot wait for a second delivery.

Procurement Verification That Catches Errors Before Shipment

Our own production lines and qualified sourced supply operate under a single warranty and a single QC standard, so the Starter Motor 6670727 you receive carries consistent quality regardless of origin facility. Eight product categories under one account mean related electrical components — solenoids, relays, battery cables — can ship in the same consignment. We accept orders from one piece, so a single emergency replacement does not require padding an order to meet a minimum. Identification from a machine model, a photograph of the nameplate, or an existing part number eliminates guesswork. Cross-reference verification covers superseded and alternate numbers across all 18 compatible Bobcat models. A sample unit can be supplied for physical fitment confirmation before you commit to a fleet-wide bulk order.

Documentation & Verification

• Commercial invoice listing Starter Motor 6670727 with full cross-reference numbers marked reference only
• Fitment sheet confirming compatibility with your specific Bobcat model serial range
• Dimensional inspection record covering bolt pattern, terminal position, and gear engagement depth
• Warranty terms covering the 3-12 month period from dispatch date
• Packing photographs showing protective crating before container loading
• HS code and customs documentation formatted for destination country clearance

Fitment Check Before Installation

• Compare the 10T drive gear tooth profile and pitch against the removed starter unit
• Verify all three mounting bolt holes align with the engine block pad without forcing
• Check terminal post orientation matches existing cable routing without bending or stretching
• Measure solenoid throw distance to confirm drive gear engagement depth specification
• Test rotation direction with a brief battery connection before final installation
• If any dimension deviates, halt installation and contact technical support with photographs

Request a Fitment Verification Before You Commit

Provide your Bobcat machine model and serial number, or send a photograph of the existing starter nameplate and mounting face. We will cross-reference the 14 listed numbers against your specific unit and return a fitment confirmation with any variant notes. For fleet orders, request a sample unit to verify physical installation on one machine before releasing the full quantity.

Frequently Asked Questions

Q: How do I confirm this starter fits my specific Bobcat excavator model and serial range? A: Send us your machine model and serial number, or a clear photograph of the existing starter nameplate. We cross-reference the Starter Motor 6670727 against our fitment database for your specific serial range, checking bolt pattern, terminal orientation, and drive gear engagement depth before confirming compatibility.

Q: My old starter has a different number — is it still listed in your cross-reference table? A: The 14 cross-reference numbers we list include superseded OEM references, re-manufacturer part numbers, and alternate designations. Numbers like 228000-6920, SND0408, and 410-52186 all map to the same physical unit. Send us your number and we will confirm whether it appears in our verified cross-reference list.

Q: Why are there multiple reference numbers for what appears to be the same starter? A: Bobcat and their component suppliers have revised part numbers across model generations and supplier transitions. The same Starter Motor 6670727 may carry different labels depending on the production year and sourcing channel. Our cross-reference table consolidates these into a single verified list so you can match any label to the correct unit.

Q: I only have my machine model with no readable part number — can you identify the correct unit? A: Yes. Provide your Bobcat model designation such as 331, E35, or S100 along with the machine serial number. We identify the correct Starter Motor 6670727 variant for your specific production run and confirm fitment details including bolt pattern and terminal position before you place an order.

Q: Can I order a sample to test fitment before committing to a larger purchase? A: We supply single sample units specifically for physical fitment trials. Install the sample on one machine to verify bolt alignment, cable reach, and cranking performance before confirming the bulk quantity for your fleet or workshop inventory.
