3/4" #18 Oil Fill Plug O-Ring

¾” #18 Oil Fill Plug O-Ring - Critical Seal for Flywheel Grinder Lubrication

This ¾” #18 Oil Fill Plug O-Ring is a vital, small sealing component designed for Van Norman FG4000, FG5000, FG10000, and FG4000R Flywheel Grinders. Its primary function is to create a secure seal for the large flat head cap screw that covers the oil filler hole on the machine table. Located on the underside of this cap screw, it is critical for maintaining the integrity of the table lubrication system, preventing lubricant from leaking and potentially mixing with grinding coolant. This O-ring is a standard component included with new FG4000, FG5000, and FG10000 machines, underscoring its importance for proper maintenance and leak prevention.

¾” #18 Oil Fill Plug O-Ring - Ensuring Integrity of Flywheel Grinder Lubrication

This ¾” #18 Oil Fill Plug O-Ring is a small yet indispensable sealing component engineered to maintain the critical lubrication system of Kwik-Way FG4000, FG5000, FG10000, and FG4000R Flywheel Grinders. Its proper function is paramount for preventing lubricant loss and ensuring the longevity and optimal performance of the machine.

Purpose and Strategic Location:

• This O-ring is specifically designed to provide a secure and reliable seal for the large flat head cap screw.
• This cap screw, in turn, covers the oil filler hole located on the machine table, providing access to the table lubricant reservoir.
• The O-ring is strategically situated on the underside of this cap screw, ensuring a tight fit when the plug is tightened.

Critical Function for Lubrication System Integrity:

The primary purpose of this O-ring is to maintain the absolute integrity of the table lubrication system. By creating a tight, leak-proof seal, it effectively prevents table lubricant from escaping. Preventing such leaks is crucial because spilled oil could potentially mix with the grinding coolant, leading to contamination that can degrade both fluids, impact grinding performance, and compromise the quality of the finished flywheel surface.

Maintenance and Operational Considerations:

• Proper Placement During Refills: When refilling the table’s oil reservoir, it is imperative to ensure that this O-ring is properly in place on the cap screw before tightening. Incorrect placement or absence can lead to immediate leaks and potential damage.
• Mindfulness During Table Top Replacement: Operators should also exercise mindfulness regarding the proper seating and condition of all O-rings when replacing the machine’s table top, as their integrity is essential for ongoing sealing and preventing fluid cross-contamination.

Standard Component for New Machines:

Underscoring its fundamental role in the machine’s design and operation, this O-ring is a standard component included with new FG4000, FG5000, and FG10000 machines. Its presence ensures that these flywheel grinders are equipped from the outset to maintain optimal lubrication and perform reliably.
