Fan Belt 6718730 Compatible with Bobcat S150 S160 – Direct Fit

Verified Fitment by Machine Serial — Every 6718730 fan belt dispatched from our Guangzhou warehouse is cross-checked against the buyer's specific Bobcat skid steer loader model and serial range before confirmation.

Why the Same Part Number Does Not Always Mean the Same Belt

Cross-reference tables copied between sellers often carry forward errors that only surface during installation.

A Fan Belt 6718730 for Bobcat Skid Steer Loader may appear identical across multiple listings, yet the actual belt required can vary depending on engine generation, pulley configuration, and production date of the machine. I have seen situations in the Pearl River Delta where a workshop received a belt that matched the part number perfectly, only to find the length was slightly off because the machine had been built during a production transition. Copied cross-reference tables rarely capture these variant-level details [NEED_CITE: skid steer loader belt drive variant identification practices].

Model Range and Serial-Level Verification

The Fan Belt 6718730 for Bobcat Skid Steer Loader spans a wide model range, from older 5600 and 773 units to the more common S150 through S205 series and track-type T180 and T190 loaders. Each model family went through engineering changes during production, and belt routing or pulley diameter may have shifted between early and late serial numbers. Confirming the exact serial range ensures the belt length and profile match the fan drive system on your specific machine, rather than relying solely on a base model designation.

Interface and Dimension Checks Before Installation

Belt fitment goes beyond matching a number. The rib profile, overall effective length, and top width must align with the pulley grooves and tensioner travel on your machine. On Bobcat skid steer loaders with enclosed engine compartments, even a slight deviation in belt length can cause improper tension, leading to slippage under load or excessive bearing wear on the fan hub [NEED_CITE: belt drive tension and bearing load relationship in compact loaders]. Before dispatch, we verify belt dimensions against the specific engine build associated with your machine serial number.

Reading the Specifications That Matter

The high-strength rubber compound used in this belt is rated for continuous tension and the elevated ambient temperatures found inside a skid steer loader engine bay, where cooling airflow is constrained by the machine's compact enclosure. ISO 9001 production controls ensure consistent dimensional tolerance across production batches. The warranty covers manufacturing defects for 3 to 12 months, which reflects the expected service window for a belt in typical construction and demolition cycling. These specifications address the actual failure modes seen in the field: heat degradation, tensile cord fatigue, and rib cracking from sustained high-load operation.

The Hidden Cost of Ordering by Number Alone

When a belt arrives and does not fit, the machine stays down while a replacement is sourced and shipped. If the belt is forced onto mismatched pulleys, premature failure follows within weeks, and the secondary damage to fan bearings or the water pump shaft can turn a simple belt replacement into a more involved repair. Workshops absorb these costs in labor and reputation, while fleet operators lose productive hours on machines that should have been back on site [NEED_CITE: cost of repeat downtime from incorrect belt fitment in compact equipment].

Why Source This Belt Through Our Guangzhou Operation

We produce selected part lines in our own facility and source the remainder from qualified ISO-certified manufacturing partners, with both carrying the same QC and warranty terms. A Fan Belt 6718730 for Bobcat Skid Steer Loader can ship alongside undercarriage components, hydraulic seals, and engine overhaul gaskets under one account and one consignment. Minimum order starts from a single piece, so an emergency replacement does not require a bulk commitment. Our technical team verifies compatibility using machine model, serial number, or a photograph of the worn belt and nameplate. Cross-reference verification covers superseded and alternate numbers. We supply samples for fitment confirmation before you commit to a larger order.

Documentation & Verification

• Commercial invoice listing part number 6718730 with cross-reference notation
• Compatibility sheet confirming fitment against your specific Bobcat serial range
• Dimensional inspection record covering belt length, width, and rib profile
• Warranty terms covering manufacturing defects for the stated period
• Packing photographs showing belt condition before crate closure
• HS code and customs documentation support for international clearance

Fitment Check Before Installation

• Compare belt length and rib count against the removed original before installation
• Verify pulley groove condition; worn grooves cause early belt failure regardless of part quality
• Check tensioner travel range to confirm the new belt falls within adjustment limits
• Run the engine at idle and observe belt tracking for the first several minutes
• If dimensions do not match, stop installation and contact us with photographs for resolution

Request a Fitment-Verified Quote

Provide your Bobcat skid steer loader model and serial number, or send a photograph of the existing belt and machine nameplate if the number is worn. We will confirm cross-reference compatibility and advise on any variant-level differences before you place an order. For fleet buyers managing multiple Bobcat units, share the full machine list so we can verify each application and consolidate into one shipment.

Frequently Asked Questions

Q: How do I confirm 6718730 fits my specific Bobcat model and serial range? A: Send us your machine model and serial number, or a clear photograph of the nameplate. We cross-check the belt dimensions against the engine build associated with your serial range and confirm fitment before you commit. This step rules out variant mismatches that copied cross-reference tables often miss.

Q: My old belt number is worn or painted over — can I order by machine model alone? A: Yes. Provide the machine model and, ideally, a photograph of the engine compartment showing pulley layout and routing. Our team uses the model and visual details to identify the correct Fan Belt 6718730 for Bobcat Skid Steer Loader variant, then verifies dimensions before dispatch.

Q: Why do some sellers list this number for different model lists? A: Cross-reference tables are frequently copied between listings without verification. The same base part number may cover different belt lengths or profiles across model generations. We verify against your serial number rather than relying on generic compatibility lists, ensuring the belt you receive matches your specific machine build.

Q: Can I get a sample to test fit before ordering in bulk? A: Sample supply is available for fitment confirmation before any bulk commitment. We ship a single Fan Belt 6718730 for Bobcat Skid Steer Loader so your workshop can verify physical fit on the machine. Once confirmed, the bulk order follows with the same verified specifications and warranty coverage.
