Why the Same Drive Pump Belt Part Number Ships Across Multiple Generations

The reference number alone does not guarantee a direct fit on every machine variant.

A single base identifier like 6736775 surfaces across compact skid steers, high-capacity track loaders, and utility vehicles spanning different production years. Copied cross-reference tables often fail to flag subtle variant differences — a Drive Pump Belt for Bobcat Loader cross reference fitment that appears correct on paper may seat poorly on a machine with a revised pulley arrangement. I have seen machines sit idle because the belt physically looped over the sheaves but slipped under load due to a groove count mismatch [NEED_CITE: skid steer loader drive belt variant identification practices].

Confirming Fitment Across the S-Series and T-Series Range

The S130 through S205 span covers machines with significantly different hydraulic pump configurations. When verifying a Drive Pump Belt for Bobcat Loader cross reference fitment, the serial number prefix matters as much as the model badge. Bobcat revised the drive pump mounting on certain S185 and S205 production runs, altering the center-to-center distance between pulleys by a small but critical margin. Requesting the machine serial range lets us narrow down which variant of the 6736775 profile your loader actually requires.

What Three Grooves and 58.15 Inches Actually Mean on the Machine

The three-groove cog profile engages the drive sheave across a wider contact area than a single-V design, distributing hydraulic pump load more evenly across the belt cross-section. At 58.15 inches in circumference and 1.19 inches in width, dimensional tolerance is held within ±0.3 mm — enough deviation to cause tracking issues on a tensioner that was set for the original specification [NEED_CITE: industrial cogged belt dimensional tolerance standards for mobile equipment]. The fiber-loaded backing resists stretching under sustained pump pressure, while the internal cord construction maintains tensile integrity during the repeated load spikes typical of loader cycling.

When the Nameplate Is Gone and the Old Belt Tells No Story

Worn nameplates and painted-over serial plates are common on machines that have been through multiple ownership changes. A Drive Pump Belt for Bobcat Loader cross reference fitment often has to be confirmed from a photograph of the existing belt, the pulley assembly, or the machine model alone. The same reference number can map to belts with slightly different cog spacing or backing thickness across model years. Identifying the correct variant before shipment prevents the situation where a belt arrives, loops on, but fails to transmit full torque to the hydraulic pump under working load.

The Cost of Installing a Belt That Almost Fits

A belt that seats on the pulleys but does not match the exact groove geometry will show no immediate problem at idle. Under hydraulic load — digging, lifting, tramming — the mismatch causes the belt to ride higher in the sheave, generating heat and accelerated wear on the cog roots. In my experience, this type of near-fit failure typically surfaces within the first few working shifts, meaning the machine goes down again just after being returned to service [NEED_CITE: premature belt failure modes in mobile hydraulic drive systems]. The hidden cost is not the belt itself but the second round of teardown, diagnostics, and lost production time.

Why Buyers Verify Here Before Committing

Our own production lines and qualified sourced supply share the same quality control standards and warranty terms, so the 6736775 you receive carries consistent dimensional verification regardless of origin. Eight equipment categories under one account means a complete drive system overhaul — belt, tensioner, pulley, seals — ships in a single consignment. Minimum order is one piece, so a fitment sample is always available before bulk commitment. Cross-reference verification covers superseded and alternate numbers across Bobcat loader generations. Our technical team confirms model-specific compatibility from serial numbers, photographs, or nameplate images, reducing the guesswork that leads to wrong-part deliveries.

Documentation & Verification

• Commercial invoice listing exact Bobcat model and belt dimensions for customs clearance
• Cross-reference sheet mapping 6736775 to alternate numbers (reference only)
• Dimensional inspection record covering length, width, and groove profile
• Warranty terms document specifying coverage period for manufacturing defects
• Packing photographs showing individual retail packaging condition before dispatch
• HS code and export documentation support for international belt shipments

Fitment Check Before Installation

• Compare groove count and belt width against the removed belt or pulley sheave before fitting
• Measure the old belt or routing path to confirm 58.15-inch length matches your machine variant
• Inspect pulley surfaces for wear grooves that could damage a new cogged belt during initial run-in
• Verify tensioner travel range accommodates the new belt thickness before applying final tension
• Run the machine at idle first and observe belt tracking for lateral drift or cog skipping

Request a Fitment-Verified Quote

Provide your Bobcat loader model, serial number, or a photograph of the existing belt and pulley assembly. We will confirm the exact 6736775 variant that matches your machine and supply a cross-reference sheet for your records. For fleet orders covering multiple loader models, share the full equipment list so each unit receives individually verified fitment data.

Frequently Asked Questions

Q: How do I confirm 6736775 fits my specific Bobcat loader when the nameplate is unreadable? A: Send us a photograph of the old belt, the pulley assembly, or the machine data plate. We cross-check groove count, belt length, and width against known Bobcat loader serial ranges to confirm the correct variant. If the plate is completely missing, the machine model alone combined with a belt photo is usually sufficient for identification.

Q: My machine model is listed — are there sub-variants that use a different belt? A: Yes. Production revisions within models like the S185 or S205 can change pulley spacing or drive pump mounting. Providing your serial number prefix lets us confirm whether your specific unit uses the standard 6736775 profile or a variant with different cog spacing or length.

Q: The old belt has no readable number, only my machine model is known — can you still identify the right part? A: We can work from the machine model combined with a measurement or photograph of the existing belt and pulleys. Groove count, length, and width narrow the identification. For less common variants, we may request a photo of the drive pump mounting to confirm routing configuration.

Q: Can I get a sample to test fitment before ordering for my whole fleet? A: Yes. Minimum order is one piece. We recommend ordering a single Drive Pump Belt for physical fitment confirmation on your machine before committing to fleet quantities, especially when dealing with mixed-model Bobcat loader fleets.

Q: What cross-reference numbers are equivalent to 6736775, and are they all dimensionally identical? A: Several alternate and superseded reference numbers map to this belt profile, but dimensional equivalence should be verified per machine variant. We provide a cross-reference sheet (reference only) showing alternate numbers and flag any known dimensional differences across Bobcat loader generations.
