SVSIID Grinding Motor Spindle O-Belt

Kwik-Way SVSII Grinding Motor Spindle O-Belt - Essential for Smooth Valve Refacing

This O-Ring Belt, designed for the Spindle Grinding Motor, is a critical component for Kwik-Way SVSII Deluxe (SVSD) and SVSII Standard (SVSS) valve refacers. Two of these “Poly Belts,” which are designed to stretch to fit and operate on both 50 Hz and 60 Hz machines, are required per spindle. They are essential for driving the grinding wheel at 3450 RPM and are specifically engineered to isolate motor vibration, ensuring a smooth, chatter-free finish. Proper installation, including maintaining motor alignment and replacing both belts simultaneously, is crucial for preventing premature breakage and optimizing performance. Note: these belts have a very tight fit, which is normal for proper tensioning.

Kwik-Way SVSII Grinding Motor Spindle O-Belt - Engineered for Precision Valve Grinding

This O-Ring Belt is a precisely engineered drive component, specifically designed for the Spindle Grinding Motor of Kwik-Way valve refacers. It is crucial for delivering power to the grinding wheel and plays a key role in the precision and finish quality of your valve refacing operations.

Application and Quantity:

• This O-Ring Belt is specifically designed for the spindle drive motor in Kwik-Way SVSII Deluxe (SVSD) and SVSII Standard (SVSS) valve refacer models. These are the crucial “spindle” belts that directly turn the “stone” (grinding wheel).

• A total of two (2) of these belts are required for installation on the spindle per machine, working in conjunction to provide balanced power transmission.

Belt Type and Compatibility:

• Identified as a “Poly Belt,” this component is uniquely designed to stretch to fit during installation. This characteristic is normal and necessary to achieve the proper tension required for effective power transfer.

• It is suitable for use with valve refacers operating on both 50 Hz and 60 Hz electrical systems, ensuring broad compatibility.

Critical Function for Grinding Quality:

• These belts are absolutely essential for the spindle’s operation, which directly drives the grinding wheel at a high speed of 3450 RPM.

• The belt-driven spindle system, particularly in the SVSII Deluxe model, is specifically engineered to isolate motor vibration. This crucial design feature contributes significantly to achieving a smooth, chatter-free finish during valve grinding, which is paramount for optimal valve performance.

Installation and Maintenance Guidelines:

• Alignment is Key: When installing a new motor or replacing belts, it is imperative to ensure that the centerline (CL) of the motor is precisely parallel to the top of the spindle slide. Failure to maintain this parallel alignment can lead to premature belt breakage and compromised performance.

• Replace in Pairs: It is crucial to always replace both belts simultaneously, never just one. Replacing belts as a pair ensures balanced tension, even wear, and consistent performance across the spindle drive.

• Tight Fit is Normal: Please note: these belts are designed for a “very” tight fit. The need to stretch the belts considerably during installation is completely normal and necessary to achieve the correct tension for effective power transmission and vibration isolation.
