Experience Strength™ C-Line Owner’s Manual: Weekly Inspection
13
Inspect Pulleys
Precor uses precision ball bearing idler pulleys to guide the cable smoothly.
Inspect each pulley for damage, including hairline cracks, chips, or missing
sections. Worn surfaces in the pulleys can cause severe damage to the
cables and must be replaced at the first sign of wear or damage.
Be certain that the wheels turn freely as the equipment is used. Inspect each
pulley for excessive side-to-side play, which indicates worn bearings or loose
mounting bolts. If excessive play is discovered, remove the pulley to inspect
the bearings and replace the entire pulley if necessary.
Inspect Weight Stack and Selector Pin
Weight stacks are made of precision machined plates that are designed as a
single mechanism to stack precisely. Use only Precor-supplied add-on
weights and weight selector pins.
On a weekly basis, inspect weight stacks and selector pins. Wipe each plate
with a damp cloth as needed. Inspect all plates for sharp burrs or damage.
Wipe dirt and dust off the guide rods.
Make sure the equipment uses only the original Precor selector pin. In
addition, make sure the selector pin can be fully inserted and retained in
each weight plate.
Inspect and Lubricate Bearings and
Bushings
Precor uses high quality bearings designed for strength applications and
long service life. Each week, do the following to maintain the bearings and
bushings on the equipment:
• Bronze bushings: Precor recommends using a small amount of silicone
spray lubricant to lubricate these bushings, which usually support rotary
shafts. Spray directly onto the shaft, and then rotate the shaft through its
complete range of motion several times. Inspect bushings for excessive
wear and damage.
Be careful when using the spray lubricant; it can stain
carpet and clothing.
Wipe off any excess lubricant with a cloth.
• Nylon bushings: Lubricate the nylon bushings on the guide rods by
applying a light coat of silicone spray lubricant. Spray the silicone
lubricant on a cloth, then wipe the cloth along the full length of the guide
rod.
• Sealed Bearing Pivot Points: These locations are protected from the
outside environment and require no lubrication. While cleaning the
equipment, wipe down the shafts and external bearing surfaces with a
cloth to prevent the buildup of dust and perspiration.
