A single drive belt tensioner pulley kit in stock fast shipping window is what separates a one-day fix from a multi-week standstill.
When a skid steer goes silent on a job site, the local dealer often quotes typical multi-week lead times for a single belt tensioner assembly. The machine sits on the hoist or behind the barrier while procurement chases confirmations. In our Guangzhou warehouse, the Drive Belt Tensioner Pulley Kit for Bobcat-compatible machines is inventoried specifically for these breakdown scenarios β not planned overhauls, but the urgent single-unit failures that stop revenue.

The problem compounds when the nameplate is worn smooth or painted over during a previous repaint. Buyers call with nothing but a machine model and a description of the pulley location. That identification gap can stretch a same-day dispatch into a week of back-and-forth emails. We close that gap by confirming compatibility from a clear photograph of the belt drive area before the order is placed.
When a message arrives at any hour with a photo of a worn belt drive assembly, the first step is matching the pulley configuration and mounting pattern to the correct kit. The Drive Belt Tensioner Pulley Kit 6735884 6662997 covers a broad range of Bobcat-compatible skid steers and compact track loaders β from the 753 to the S185 and T190. Once the photo confirms the hub and fan pulley layout, stock status is verified against live warehouse inventory and the dispatch window is quoted in the same reply. No waiting for a warehouse manager to open a spreadsheet the next business day.
The total time from order to installation breaks into three segments: warehouse picking and packing, handover to the freight forwarder, and transit to the destination. For this drive belt tensioner pulley kit in stock fast shipping orders, the Guangzhou warehouse segment typically completes within one working day. Air express routes deliver to most international destinations within a few days of handover. Sea freight extends this to several weeks but suits restocking orders where the machine is already running on a temporary fix. We quote the estimated arrival date for each option at the inquiry stage, so the decision between speed and cost is made with full information.

The forged steel hub on this belt tensioner provides the mass and rigidity needed to absorb the cyclic loading from belt engagement and disengagement. A cast or stamped hub would flex under the same tension cycles, accelerating bearing wear. The pre-greased sealed bearing unit eliminates the need for field lubrication β once installed, the tensioner runs until the next scheduled belt service without attention. The surface hardness specification of HRC 58β62 (source value β verify against manufacturer catalog) on the pulley contact face resists the micro-abrasion caused by belt dust and fine particulate that accumulates in the drive enclosure. Dimensional tolerance of Β±0.05 mm (source value β verify against manufacturer catalog) keeps the pulley running true without lateral runout that would otherwise saw through belt cords prematurely.
Ordering the wrong tensioner kit based on an incomplete cross-reference means the machine stays down through a second shipping cycle. A pulley with an incorrect mounting pattern or hub depth may bolt on but sit misaligned by a fraction of a millimeter β enough to shred a new belt within the first day of operation. The bearing in a mismatched unit may carry the load but run hotter due to preload differences, failing within weeks instead of months. Each misidentification adds not just the cost of a return shipment but the compounding expense of crew standby, rental equipment extension, and missed project milestones.

Our Guangzhou warehouse maintains ready-to-ship inventory on high-failure belt drive components, and this tensioner kit is stocked specifically because belt system failures are rarely planned. Single-piece minimum order means a workshop repairing one S175 does not need to justify a bulk purchase. Part identification from a machine photograph β when the nameplate is illegible or missing β eliminates the most common cause of wrong-part shipments. Cross-reference verification covers both 6735884 and 6662997 along with superseded and alternate numbers that appear in older service manuals. The six-month warranty against manufacturing defects applies whether the order is one piece or fifty. Technical team availability for compatibility confirmation means questions about variant differences across model generations are answered before the order is placed, not after the wrong kit arrives on site.
Send the part number visible on the old tensioner label, or if that is unreadable, a clear photograph of the belt drive area showing the pulley and mounting bracket. Include the machine model β for example S175 or T180 β so we can cross-check the fitment range against your specific serial number bracket. We will reply with confirmed stock status, the dispatch date, and estimated arrival for your preferred freight option, all in the same message.
Q: Is this belt tensioner kit in stock and when can it ship? A: The 6735884 6662997 Drive Belt Tensioner Pulley Kit is held in our Guangzhou warehouse for immediate dispatch. Once your order is confirmed and compatibility is verified β typically within the same conversation β the kit is picked, packed, and handed to the freight forwarder within one working day. Express air options are quoted with an estimated arrival date at the time of inquiry.
Q: Can I order just one piece for an urgent repair? A: Yes. The minimum order quantity for this tensioner and fan pulley kit is one piece. We stock this kit specifically for emergency breakdown situations where a single skid steer or compact track loader is down and waiting on parts. There is no bulk requirement to qualify for dispatch or warranty coverage.
Q: My machine nameplate is gone β can you identify the part from a photo? A: Yes. Send a clear photograph of the belt drive area showing the tensioner pulley, fan pulley, and mounting bracket. We match the visual configuration against known variants for Bobcat-compatible machines including the S130 through S205 and T140 through T190 ranges to confirm the correct kit before you commit to an order.
Q: How fast does express delivery reach my location? A: Air express transit times vary by destination country and customs clearance speed. For most international locations, the drive belt tensioner pulley kit in stock fast shipping orders arrive within several business days of dispatch from Guangzhou. We provide the estimated arrival window for your specific address at the inquiry stage so you can plan the repair schedule.
Q: What happens if the part arrives and does not fit? A: If compatibility was confirmed by our team based on the information you provided and the kit does not fit, we work to resolve the issue promptly. This is why we emphasize sending machine model details and photographs before ordering β verified identification at the inquiry stage prevents mis-shipments and keeps your machine from sitting idle through a second delivery cycle.
