6602-001655 Samsung BELT TIMING GEAR;RUBBER RED/YEL T2.4 W8 OEM is a synchronous belt/gear element manufactured for use in Samsung appliances; it is indeed a rubber timing gear (belt segment or pulley interface) with color coding adn nominal dimensional identifiers. The designation T2.4 typically refers too a 2.4 mm tooth pitch profile while W8 is commonly used to indicate an 8 mm belt width or pulley face width, and the OEM tag denotes original equipment specification. As a molded rubber timing component, it is intended to engage a corresponding toothed belt or gear train to transmit torque without slippage and to preserve phase/position between rotating members.
Inside an appliance the component functions as part of the synchronous drive train, transmitting rotational motion from a motor or idler to the driven element (such as a drum, cam, or gearbox input) while maintaining timing relationship. It interacts directly with the motor shaft, belt, pulleys/idlers, tensioning devices and, indirectly, with control electronics or sensors that rely on consistent angular position. Proper engagement, alignment and tension of the timing gear are therefore critical to coordinated mechanical actions such as drum rotation, valve or cam actuation, and the avoidance of asynchronous operation or mechanical interference.
This article will explain the component’s functional role, how to interpret it’s dimensional markings and OEM number for compatibility, common failure symptoms to watch for (tooth wear, cracking, glazing, loss of tension, noise, and loss of synchronization), and practical troubleshooting steps technicians can use (visual inspection, pitch/width verification, tension and alignment checks, and load testing). It will also cover replacement considerations: matching pitch, width and length or mating pulley profile, inspecting associated pulleys and bearings, recommended installation practices, and safety precautions to ensure reliable reassembly and restore correct appliance operation.

Function and Role of the Belt Timing Gear in samsung Drive and Tension Systems
The 6602-001655 Samsung BELT TIMING GEAR;RUBBER RED/YEL T2.4 W8 OEM is a molded rubber timing pulley designed to engage a T2.4 tooth-profile timing belt and transmit synchronous motion in belt-driven Samsung assemblies. Its elastomeric construction provides controlled compliance that reduces impact loads on mating gear teeth and dampens operational noise, while the precise tooth spacing maintains positional accuracy between motor and driven components. the designation W8 denotes an 8 mm belt width compatibility and the red/yellow mold coloring is a factory identifier for correct part placement during assembly and service.
In service the part behaves as both a power-transmission and damping element: wear typically appears as tooth rounding, rubber hardening, or loss of profile leading to increased backlash or belt skipping. Compatibility is resolute by matching the T2.4 tooth profile, belt width, and the hub/shaft interface; replace the gear with an identical OEM unit when belt replacement is required to preserve pitch accuracy and load distribution. Practical installation checks include verifying axial seating, correct belt tension, and alignment with adjacent idlers or tensioners-common faults traceable to this gear are intermittent slipping, increased vibration, and accelerated belt wear.
- Common symptoms: tooth wear, cracking of rubber, increased noise, belt skip.
- Installation tips: confirm belt pitch/profile, set correct tension, inspect shaft bore and fasteners.
- Maintenance: replace gear and belt together if dimensional wear or rubber degradation is present.

How the 6602-001655 Samsung BELT TIMING GEAR;RUBBER RED/YEL T2.4 W8 OEM Operates Within the Appliance Drive Assembly
The 6602-001655 Samsung BELT TIMING GEAR;RUBBER RED/YEL T2.4 W8 OEM serves as a flexible toothed timing belt inside the appliance drive assembly, transferring rotary motion from the motor hub to the driven component (drum, transmission input or idler) while preserving synchronous timing. Constructed from a molded rubber compound with a T2.4 tooth pitch and an effective width denoted by W8,the part engages matched pulley profiles to provide positive engagement with minimal backlash. Its rubber construction provides controlled elasticity that dampens transient loads and reduces shock to gear trains, but correct functional behavior depends on exact matching of tooth pitch, belt width, and routing geometry to the mating pulleys and tensioning system in the specific Samsung assembly.
In service the component transmits torque through tooth shear and friction against pulley flanks; common wear modes include tooth deformation, elongation from mechanical creep, and surface glazing from heat, each of which degrades engagement and can cause slipping, noise, or irregular rotation. Practical replacement and troubleshooting focus on verifying pitch and width compatibility, inspecting pulley tooth profiles and bearings, setting the specified belt tension, and avoiding cross‑compatibility with non‑T2.4 pulleys. For example, a belt exhibiting missing or rounded teeth or visible elongation should be replaced and the pulley alignment checked to prevent rapid re‑failure.
- Compatibility checks: confirm T2.4 tooth pitch, W8 belt width, and OEM part interface before installation.
- Failure symptoms: audible squeal, intermittent spin, visible tooth wear or belt stretch.
- installation tips: avoid over-tensioning, ensure pulley alignment, and replace worn idlers/bearings simultaneously.

Common Failure Symptoms and Wear Patterns Indicative of Belt Timing Gear Degradation
The 6602-001655 Samsung BELT TIMING GEAR;RUBBER RED/YEL T2.4 W8 OEM is a molded rubber timing gear that transmits rotational timing between the drive motor and the driven assembly in select Samsung laundry and appliance mechanisms. its T2.4 tooth pitch and W8 (8 mm) width define the meshing geometry with corresponding timing belts; correct pitch and width are required to maintain positive engagement, avoid belt slip, and preserve synchronous motion. Under normal operation the rubber compound absorbs transient shock and damps high-frequency vibration, but repeated cyclic loading, heat, chemical contamination (detergent or oil), or misaligned pulleys changes the profile and compliance of the teeth, producing measurable effects such as increased motor torque draw, intermittent engagement (skipping), or rhythmic noise tied to the drum or pump rotation-for example, a technician may observe a periodic chirp that correlates with a specific angular position of the assembly when one or more teeth have rounded or lost material.
- Audible chirping or squeal at low speed and under load (indicative of tooth edge glazing or partial contact).
- Intermittent slipping or skipped cycles (visible as irregular drum rotations or erratic timing of pumps).
- Visible tooth rounding, cracking, or chunking on the rubber profile.
- Excessive lateral movement or wobble of the belt/gear interface (misalignment or bearing play).
- Material hardening or compression set where teeth no longer spring back to profile.
| Item | Description |
|---|---|
| Part / Pitch / Width | 6602-001655; T2.4 tooth pitch; W8 (8 mm) width. |
| Material | Molded rubber compound-designed for flexibility and damping; degrades with heat, oil, or abrasion. |
| Typical failure mode | Tooth wear/rounding,glazing,cracking,compression set,or contamination-induced abrasion causing loss of engagement. |
Wear patterns that indicate imminent replacement include uniform tooth profile loss across the gear face (abrasive wear) versus localized relief or chunking that points to transient overload or foreign-object damage. Inspect for surface glazing (smooth shiny faces), which reduces coefficient of friction and promotes slip, and for micro-cracking at the root of teeth which precedes larger fracture. Practical inspection methods include comparing the gear profile against a known-good sample, measuring tooth spacing and height with calipers or a profile gauge, checking belt tension and alignment, and monitoring motor current for step changes under controlled loading; if measurements show reduced tooth height, altered pitch engagement, or persistent belt tracking issues, replace with a matching geometry OEM part to restore synchronous operation rather than attempting repairs that change the effective pitch or compliance of the drive train.
Replacement Considerations,Compatible Appliance Models,and Installation Best Practices
The 6602-001655 Samsung BELT TIMING GEAR;RUBBER RED/YEL T2.4 W8 OEM is a molded rubber timing belt with a T2.4 tooth profile and an 8 mm wide engagement surface. It transmits synchronous motion between a motor and a driven component, maintaining phase alignment and providing damping of torsional vibration; the molded rubber compound and reinforcement give small amounts of elasticity while preserving tooth form under load. Typical failure modes are tooth wear or shear, rubber hardening or cracking, and contamination from oil or lint that reduces friction and causes slippage-symptoms seen on the machine include intermittent drive, unusual noise at the pulley interface, and visible tooth deformation. Confirming the T2.4 profile and W8 width during replacement ensures correct meshing and avoids premature tooth stripping or skipped engagement on the mating pulley.
Compatibility checks and installation best practices focus on dimensional match, pulley condition, and tensioning. Verify the part number and dimensions against the service manual, inspect mating pulleys for tooth wear or eccentricity, and replace worn bearings or pulleys rather than fitting a new belt to a damaged drive; damaged pulleys accelerate belt failure.During installation, keep mating surfaces free of lubricants, seat the belt fully into pulley roots before applying final tension, and perform a short no-load run-in while monitoring for noise and rechecking tension after a few cycles. Practical examples include replacing the belt when motor-replacement downtime already exposes pulleys, or swapping the belt and pulley together in older machines where tooth wear is evident-these approaches minimize repeat service calls and ensure reliable synchronization.
- Confirm profile and width: T2.4,W8; measure pitch and width before ordering replacements.
- Inspect and, if necessary, replace mating pulleys and bearings to prevent accelerated wear.
- Clean pulleys of debris and oils; avoid grease contamination during assembly.
- Set and verify belt tension per manufacturer specification; recheck after initial run-in.
- Look for visual signs: tooth shear, glazing, cracking, or elongation before reuse.
