What spare parts or bench stock should I keep on hand?
We recommend keeping a bench stock of commonly replaced parts so your team can make quick repairs without waiting for shipments. Having parts on site maximizes uptime and keeps your production line moving.

​

Why is having bench stock important?
Bench stock allows you to perform simple repairs immediately. Even though FPS ships most stocked parts within 24 hours, having the right components already on hand eliminates downtime and keeps your equipment running within proper specifications.

​

Does FPS offer spare parts kits?

Yes. FPS offers spare parts kits sized to the equipment in your system, including:

• Single or Dual Shaker (SAS/DAS): Kits include enough parts to fully repair one shaker. A typical shaker kit includes items such as fiberglass arms (slats), shims, isolators, hardware, and wear components. These are OEM spec parts designed to maintain the shaker’s performance and vibration characteristics.

• Systems with Three or More Shakers (TAS): Kits include enough parts to repair two shakers. We also offer recommended spare parts packages for drum breaders, tunnel breaders, conveyors, and other major FPS equipment.

​

Do I need to use FPS OEM parts?
Yes. While aftermarket parts exist, they often do not meet FPS tolerances. Our arms, isolators, and other components are engineered to specific spring constants and performance specs. Using non OEM parts can cause improper operation, excessive vibration, or damage to the equipment.

​

Why are FPS arms and isolators red now?
FPS updated the color for branding and identification. Arms and isolators were previously blue or green, but all new components are now red. Customers often ask about this change, especially when older documentation references blue isolators.

How fast do parts ship?

• Stocked parts: Ships the same day or within 24 hours.

• Made to order or vendor supplied parts: Lead times vary. FPS will provide a quote and estimated delivery timeframe.

​

Do customers typically purchase spare parts kits?
Yes. More than half of FPS customers purchase recommended spare parts packages because they recognize the value of minimizing downtime and maintaining OEM performance.

​

Do service contract holders receive discounts on parts?
Yes. Customers with an FPS service contract receive 10% off parts.

​

How do I get a service contract?
Contact FPS directly. We’ll help you choose the right contract length and visit frequency based on your equipment and production needs.

​

Why is my shaker shaking violently? 
Check the isolator bolts. They are designed to function like pins and should not be fully tightened. Refer to your owner’s manual for proper adjustment.

​

Why won’t my isolator bolts tighten all the way?
They are intentionally designed not to fully tighten. Over tightening can cause severe vibration issues.

​

Why isn’t my shaker shaking at all?
Check for isolator lockouts left in place after shipping.

​

Are my motors running the right direction?
Shaker motors must rotate in opposite directions.

​

How many arms/slats does my shaker have?
Refer to the parameter plate in your manual. The number of arms on the left and right sides must match.

​

Can I replace arms on only one side?
No. Arms must be replaced in matching pairs on both sides. Ideally, replace all arms at once.

​

Can I use nylon lock nuts on shaker arms?
No. Use a lock washer and torque to 24–25 ft lbs.

​

Why is my shaker loud or noisy?
Check for loose pan clamps.

​

Can I speed up my shaker or adjust the Hertz?
No. Contact FPS for proper guidance.

​

Can I run my shaker uphill?
Yes.

​

How do I determine left vs. right side of the shaker?
Stand at the end of the equipment looking toward the discharge end. Your left is the shaker’s left; your right is the shaker’s right.
