Understanding the Gravely drive belt diagram is crucial for lawn mower owners and mechanics aiming to optimize performance.
This guide covers each component, from the hex belt to the pulleys and idler arms, providing a comprehensive understanding.
By the end, you’ll confidently grasp the Gravely drive belt diagram, enabling you to identify and address potential issues effectively.
The Gravely lawn mower’s drive belt has several important mechanical parts. In the following sections, we’ll explain each of these parts and provide their prices for easy reference.
The wrapped hex belt (1) encircles the pulleys, connecting the engine’s driving pulley to the cutting blade pulley, and forming a vital power loop. The belt transfers the engine’s rotational force to the cutting blades, ensuring efficient power transfer.
It’s priced at $79.15.
The Gravely mower utilizes a strong power transmission system comprising a cogged V-belt and a wrapped hex belt. These belts work together to boost performance and reliability.
The cogged V-belt is designed for demanding applications, ensuring efficient power transfer while reducing slippage risk. It significantly improves the Gravely mower’s overall performance when used with the wrapped hex belt.
This high-quality cogged V-belt is competitively priced at $51.65, making it a cost-effective choice for maintaining and optimizing your Gravely mower’s power transmission system.
The drive belt system relies on bolts (3, 9, 13, 20, 24, 28, 31, 34, 36, 38) and spacers (4) for various assembly points, including idler pivot arms, bearing pedestals, and pulleys.
These components are typically inserted through pre-drilled holes and secured with nuts. Bolts and spacers provide structural support, ensuring precise part alignment and separation.
Additionally, they help maintain optimal belt tension and reduce excessive friction. Bolts range from $1.05 to $6.55 each, while the spacer costs $10.95.
Cap idlers (6) are usually placed near the pulleys and drive belt assembly on the mower deck to support and guide the drive belt.
Gravely Cap idlers act like pulleys, maintaining drive belt alignment and tension, priced at $14.25.
The mower deck features idler pivot arms (7, 18, 32), which serve as pivot points for the cap idlers and are connected to the bearing pedestals.
These cap idlers can adjust their position in response to the drive belt’s tension via the idler pivot arms. Their prices range from $41.95 to $83.79.
Bearing pedestals (8) are installed on the Gravely mower deck to provide support for the cap idlers and idler pivot arms.
They are typically secured to the Gravely deck structure using bolts and washers, with a cost of $73.45.
Near the idlers and arms on the Gravely mower deck, you’ll find extension springs (10, 29). These springs are strategically attached to both the mower deck and other auxiliary components. Their crucial role is to maintain the drive belt’s precise engagement with the pulleys by applying the necessary tension.
The extension springs are available in two variants, priced at either $32.95 or $25.25.
Pulleys (22, 23, 35) are integral components found on the engine’s driving shaft, the cutting blade shaft, and along the path of the drive belt. These pulleys feature grooved surfaces and rotate, serving as crucial support and guidance for the Gravely drive belt.
Their primary role is to provide the drive belt with a firm grip, ensuring its proper function. Additionally, the size and arrangement of these pulleys can impact the speed and torque of the blades.
The cost of these pulleys ranges from $65.95 to $92.35.
The Assembly PTO Idler (30) is critical for maintaining drive belt tension when the PTO is engaged. It’s located near the PTO assembly.
This idler includes a pulley or roller, bracket or arm, and mounts securely on the Gravely mower deck or frame. Its primary job is to ensure the drive belt maintains proper tension and engagement with the PTO pulleys.
Operators can adjust the Gravely drive belt tension as needed using this component, which is priced at $69.83.
Washers (11, 14, 21, 27) are used in various locations on the Gravely mower. They serve to distribute weight and provide a smooth surface for rotation between bolts, nuts, and other components.
These washers act as spacers, reducing friction and ensuring smooth hardware rotation. Their prices range from $0.50 to $3.91.
These nut couplings play a crucial role in maintaining the integrity of the Gravely drive belt system components. By tightening the nut connection, they keep the parts securely in position, preventing unintentional movement or disassembly during use. Nut couplings are priced at $3.58.
Common problems associated with damaged Gravely drive belt components include:
To ensure optimal performance and safety, regular maintenance and prompt replacement of damaged Gravely drive belt components are essential.
Maintaining the drive belt on your Gravely lawn mower or equipment is crucial to ensure optimal performance and longevity. Here are some maintenance tips to keep your Gravely drive belt in good condition:
By following these steps, you’ll help prolong the life and efficiency of your Gravely drive belt.
A Gravely drive belt diagram serves as a visual guide, outlining the routing of the drive belt in lawn mowers and tractors. This diagram is vital for maintenance, ensuring proper power transmission from the engine by illustrating the path through pulleys and idlers.
