Main Pump Drive Belt 6667322 for Bobcat S175 – Verified Fitment

Verified Cross-Reference — Each 6667322 belt is checked against Bobcat loader serial ranges before dispatch to prevent variant mismatch.

Why the Same Reference Number Can Still Deliver the Wrong Belt

Superseded numbers and variant splits across Bobcat loader generations mean the same base reference may yield mismatched fitment without serial-level verification.

A belt that looks identical to the old one can have a slightly different tooth profile or cord construction, causing slippage under hydraulic load or premature cracking. I have seen loaders sit idle for days because the replacement belt matched the part number but not the specific production run variant. Cross-reference tables copied between sellers often carry forward errors from superseded numbers, compounding the risk [NEED_CITE: aftermarket belt cross-reference accuracy in compact loader service]. The Main Pump Drive Belt 6667322 for Bobcat Skid Steer Loader requires confirmation that the machine serial number falls within the correct range, not just that the model name appears on a compatibility list.

Serial Range Verification Across Bobcat Loader Generations

The 6667322 reference covers a wide span of Bobcat machines, from the 653 and 751 early loaders through to the S205 and T190 current production units. Within that span, Bobcat made running changes to pulley diameters and tensioner positions that altered belt requirements even when the model designation stayed the same. A Main Pump Drive Belt 6667322 for Bobcat Skid Steer Loader must be matched against the exact serial number, not just the model badge, to confirm groove spacing and belt length are correct for that specific machine build.

Distinguishing Pump Drive from Fan Drive on the Same Machine

Several Bobcat loader models use belts of similar appearance on both the hydraulic main pump and the cooling fan circuit. The pump drive belt transmits significantly higher torque and requires the fiber-loaded backing with cord reinforcement specified for 6667322. A fan-side belt substituted into the pump position will stretch and slip under load, while the correct pump belt in the fan position may overtension the fan bearing [NEED_CITE: belt drive application differentiation in skid steer hydraulic systems]. Always confirm which drive circuit the old belt was removed from before ordering the replacement.

Belt Profile and Groove Geometry Check

The 3-groove flat cogged profile on this belt must match the pulley sheave dimensions precisely. Groove depth, groove spacing, and the cog profile on the backing side all affect how the belt seats and transmits power. Aftermarket belts that approximate rather than replicate the original profile will ride higher in the sheave, reducing contact area and generating excess heat. The fiber-loaded backing with additional cord support maintains dimensional stability across the operating temperature range, preventing the belt from elongating and losing tension during sustained hydraulic work.

The Cost of a Belt That Almost Fits

A belt with the right length but wrong groove profile will mount on the pulleys and may even run for the first few hours. Under sustained hydraulic pump load, the mismatch causes the belt to ride out of the sheave grooves, generating heat and accelerated wear on both the belt and the pulley faces. The machine returns to the fault state, now with a damaged pulley adding to the repair scope [NEED_CITE: belt drive misalignment failure modes in mobile hydraulic equipment]. For fleet operators running multiple Bobcat units, one incorrect belt in stock can mean repeated emergency orders and compounding downtime across machines.

Why Source This Belt Through XUNPO

Own production on selected belt lines and qualified sourced supply operate under one account and one warranty, so the Main Pump Drive Belt 6667322 for Bobcat Skid Steer Loader ships with the same QC terms regardless of which facility produced it. Eight product categories mean associated tensioner components and seal kits can ship in one consignment rather than split freight. Orders start from one piece, so a single emergency replacement does not require meeting a minimum quantity threshold. Part identification works from a part number, machine model, photograph, or nameplate image when the original tag is unreadable. Cross-reference verification covers superseded and alternate numbers to catch errors before the belt ships. Sample supply lets you confirm physical fitment on the machine before committing to a bulk order for the fleet.

Documentation & Verification

• Commercial invoice and packing list with belt part number and quantity confirmed
• Compatibility and cross-reference sheet marking 6667322 as reference only
• Dimensional inspection record covering groove count, belt length, and backing construction
• Warranty terms document covering 3-12 months against manufacturing defects
• Packing photographs showing belt condition and packaging before crate seal
• HS code and customs documentation support for international belt shipment

Fitment Check Before Installation

• Compare groove count and belt width against the removed belt before mounting
• Verify belt seating depth in both pump and drive pulleys by hand rotation
• Check tensioner arm travel range with new belt installed at rest position
• Run machine at idle for initial seating, then re-check tension after warm-up
• If profile mismatch is found, halt installation and request cross-reference re-verification

Getting the Right Belt Identified

Provide the Bobcat machine model, serial number, and a photograph of the old belt or nameplate if readable. If the belt number is worn off, a clear image of the pulley arrangement and tensioner helps confirm which drive circuit is involved. With this information, we verify the correct 6667322 variant against the serial range and send a compatibility confirmation before any order is placed.

Frequently Asked Questions

Q: How do I confirm this belt fits my specific Bobcat loader model and serial range? A: Send the machine model and serial number from the identification plate. We cross-check the serial against the production range for the 6667322 belt to confirm groove profile and length match your specific build variant. A compatibility sheet is provided before shipment.

Q: The old belt number on my machine is different — is 6667322 still the correct replacement? A: Bobcat superseded several belt references across loader generations. Send us the old number and your machine serial. We verify whether 6667322 is the current valid cross-reference for your specific production run, or if a different number applies.

Q: Why do some listings for the same reference show different belt constructions? A: Variant differences exist within the same base reference across Bobcat production years. Some listings may show belts intended for fan drive rather than pump drive. We confirm the exact application circuit and belt construction required for your machine serial before supply.

Q: I only have the machine model, no readable part number — can you identify the right belt? A: Yes. Provide the Bobcat model and serial number, plus a photograph of the drive pulley area if possible. We identify the correct belt from the machine specification rather than relying on a worn or missing part tag.

Q: Can I order a single sample to verify fitment before placing a larger order? A: Single-piece orders are accepted with no minimum quantity requirement. Order one belt, confirm physical fitment and performance on your machine, then proceed with confidence to a bulk order for the fleet.
