Bobcat Skid Steer-Compatible Belt Tensioner Kit – Model-Matched

Serial-Range Verified Fitment — We cross-check every Bobcat skid steer and track loader serial number against the 12-component tensioner kit to rule out variant mismatches before shipping.

Why the Same Base Number Arrives in Multiple Kit Variants

Confirm the serial number, not just the model badge — Bobcat revised tensioner hardware across production runs without changing the primary reference.

A Belt Tensioner Kit 6662997 for Bobcat Skid Steer fitment cross reference covers a broad model span, but the 12-component contents have shifted across production years. [NEED_CITE: aftermarket cross-reference accuracy standards for compact equipment driveline components] I have encountered situations where the idler pulley outer diameter matched perfectly, yet the bearing seat profile had been reworked in a later revision — producing noise within hours of installation. Relying on the model plate alone skips the serial-level detail that separates a direct fit from a costly return.

Coverage Across Skid Steer, Track Loader, and Wheel Loader Lines

This Belt Tensioner Kit 6662997 for Bobcat Skid Steer fitment cross reference spans 28 machine models across three chassis families. The S-series, T-series, and A-series machines share the same base tensioner architecture, but mounting flange thickness and arm swing arc differ by chassis. We verify your specific serial range against the kit variant to ensure the arm 6725212 and retainer 6702474 seat correctly in your accessory drive bracket.

Interface Verification Before the Wrench Turns

What to Measure When the Old Kit Comes Off

The idler pulley bore, the arm pivot pin diameter, and the spring free length are the three dimensions that determine whether a Belt Tensioner Kit 6662997 for Bobcat Skid Steer fitment cross reference will function correctly on your machine. Bearing 6655781 must spin freely with no axial play once pressed into the pulley. The bushing 6704443 outer surface should show uniform contact with the housing bore — any gap indicates the housing itself needs attention before the new kit goes in.

Specification Breakdown for the 12-Piece Kit

The fan drive idler pulley at the heart of this assembly carries the primary radial load from belt tension. Its bearing 6655781 is a sealed unit; once contaminated with grit, it cannot be re-greased through the grease ring 6660995 alone — the seal path must remain intact from installation. Spring 6700115 provides the static tension force, and its rate must match the belt span length for your engine configuration; too stiff and bearing load accelerates wear, too soft and the belt slips under fan load. The two screws (38C820 and 73G656) serve different thread pitches and lengths, so swapping them during reassembly creates clamp-load imbalance on the arm pivot. O-ring 6704820 seals the tensioner body against coolant or debris ingress depending on whether the drive is mounted on the wet or dry side of the engine compartment.

The Cost of Installing a Variant That Almost Fits

A tensioner that physically bolts on but carries the wrong spring rate or bushing dimension produces symptoms that mimic belt wear or fan clutch failure. The machine runs, but belt chirp at idle or rising coolant temperature points technicians toward the wrong diagnosis. [NEED_CITE: diagnostic misdirection from belt drive tensioner variance in compact loaders] This sends a machine back into the bay for a second teardown, doubling the labor cost and extending the downtime window well beyond what a proper serial-range check would have prevented.

Why Procurement Starts With a Serial Number Here

We produce selected part lines in our own facility and source the remainder from qualified ISO-certified partners, and both streams carry the same warranty terms — so a Belt Tensioner Kit 6662997 for Bobcat Skid Steer fitment cross reference ships under one accountability. Eight equipment categories under one account means the belt, coolant hoses, and fasteners for the same repair can move as a single consignment. Our technical team cross-references superseded numbers like 6702474 and 6725212 against your serial range before confirming the kit. Samples are available for physical fitment trials before you commit to bulk quantities across a mixed-model fleet.

Documentation & Verification

• Commercial invoice listing all 12 kit components with individual reference numbers
• Fitment and cross-reference sheet marking each OEM number as reference only
• Dimensional inspection record covering pulley bore, spring free length, and bushing OD
• Warranty terms covering manufacturing defects for 3–12 months
• Packing photographs taken before carton closure
• HS code classification and customs documentation support

Fitment Check Before Installation

• Measure housing bore for bushing 6704443 press fit — reject if ovality is visible
• Spin bearing 6655781 by hand and check for axial play before pressing into pulley
• Compare arm 6725212 pivot hole diameter against the old unit to catch housing wear
• Verify spring 6700115 free length matches the removed unit within tolerance
• Confirm O-ring 6704820 cross-section seats fully in its groove without rolling
• Torque screws 38C820 and 73G656 to specification using their distinct thread pitches

Requesting a Fitment Confirmation

Send your machine model, serial number, and a photograph of the old tensioner assembly or nameplate. Our technical team will map the serial range to the correct kit variant, resolve any superseded part numbers, and confirm component compatibility before you place an order.

Frequently Asked Questions

Q: How do I confirm this kit fits my specific Bobcat machine model and serial number? A: Provide your machine model and the serial number from the chassis plate. We cross-reference the production range against the kit variant to verify that the arm, retainer, and bushing dimensions match your engine build. A fitment sheet ships with the order documenting the match.

Q: My old part number differs from 6662997 — is it still the same kit? A: Numbers like 6702474, 6725212, and 6655781 are cross-reference designations (reference only) for individual components within this 12-piece assembly. We verify whether your existing number maps to the same kit revision or a superseded variant, and advise accordingly before shipping.

Q: What if the same base number has different component variants across model years? A: Bobcat revised hardware across production runs without always changing the primary reference. We check your serial range to identify the correct spring rate, bushing dimension, and screw thread specification. A sample is available for trial fitment when uncertainty exists.

Q: I only have the machine model, no readable part number — can you identify the right kit? A: Yes. Send the machine model and a clear photograph of the nameplate or the existing tensioner assembly. We use the model and visual details to narrow the serial range and confirm which kit variant fits, then provide a compatibility statement before dispatch.

Q: Can I order a sample to test fitment before placing a bulk order? A: Samples ship under the same warranty and quality terms as production orders. This is recommended for distributors adding Bobcat-compatible belt drive lines to their catalog or for fleet operators standardizing tensioner supply across mixed-model sites.
