Clock Movement Time Side 2nd Wheels - Original Replacement Gears
Welcome to our specialized collection of authentic clock movement 2nd wheels (also called center wheels or second wheels) from antique and vintage timepieces. The time side 2nd wheel is a critical gear in every mechanical clock movement, transferring power from the mainspring to the rest of the time train and typically driving the minute hand motion works. When this essential clock gear is damaged, worn, or has broken teeth, your entire clock stops functioning. These genuine replacement clock gears provide the authentic components needed to restore your clock movement to reliable operation.
Understanding the Time Side 2nd Wheel
The 2nd wheel (or center wheel) occupies a crucial position in the clock's gear train. Understanding its function helps you identify the correct replacement part for your movement.
What Is the 2nd Wheel?
In clock terminology, wheels are numbered based on their position in the power transmission sequence:
- Great Wheel (1st wheel) - Connected directly to the mainspring barrel
- 2nd Wheel (Center Wheel) - Our focus - connects great wheel to 3rd wheel
- 3rd Wheel - Intermediate gear in the time train
- 4th Wheel (Escape Wheel) - Final wheel before the escapement
The time side 2nd wheel specifically refers to the center wheel in the timekeeping train (as opposed to the strike train or chime train, which have their own separate gear trains).
Functions of the 2nd Wheel
This critical clock movement gear serves multiple essential functions:
Power Transmission:
- Receives rotational power from the great wheel
- Transfers power to the 3rd wheel and rest of time train
- Reduces speed through gear ratio
- Part of the mechanical advantage system
Motion Works Connection:
- Often has extended arbor (shaft) that passes through the dial
- Connects to minute wheel and hour wheel
- Drives the clock hands through motion works
- Rotates once per hour in most clock designs
Timing Ratio:
- Gear tooth count determines speed reduction
- Works with pinion to create specific ratios
- Critical for accurate timekeeping
- Part of calculated gear train design
Why 2nd Wheels Fail
Clock 2nd wheels can fail or require replacement for several reasons:
Broken Teeth:
- Most common problem with vintage clock gears
- Caused by excessive wear, metal fatigue, or improper meshing
- Even one broken tooth stops the entire movement
- Cannot be easily repaired - replacement usually necessary
Wear:
- Decades of operation wear teeth profiles
- Worn teeth cause power loss and poor timekeeping
- Teeth can become thin or pointed
- Excessive wear prevents proper meshing with pinions
Bent or Damaged Arbor:
- The shaft (arbor) can bend from impact or improper handling
- Bent arbors cause binding and uneven tooth engagement
- Damaged pivot points cause excessive friction
- Arbor damage often requires wheel replacement
Corrosion:
- Rust or verdigris on brass wheels
- Compromises structural integrity
- Rough surfaces increase friction
- Corroded wheels should be replaced
Poor Previous Repairs:
- Amateur attempts to fix broken teeth
- Incorrect replacement wheels that don't match specifications
- Modified wheels that damage other components

Why Tooth Count and Profile Matter
Unlike some clock parts where "close enough" might work, clock movement gears require precise matching:
Tooth Count Critical:
- Must match original exactly
- Determines gear ratio in time train
- Wrong tooth count = incorrect timekeeping
- Even one tooth difference causes problems
Tooth Profile Important:
- Different eras used different cutting methods
- Tooth shape affects meshing smoothness
- Profile must match pinion design
- Improper profile causes excessive wear
Pitch (Tooth Spacing):
- Distance between teeth must match
- Measured as "module" in metric or "diametral pitch" in imperial
- Incompatible pitch won't mesh properly
- Causes noise, binding, and rapid wear
Arbor Specifications:
- Shaft diameter must fit movement plates
- Pivot size must match pivot holes
- Length must be correct for dial thickness
- Extended arbors for motion works must have correct length
The Measurement Challenge
Identifying the correct replacement clock 2nd wheel requires careful observation and measurement:
What to Measure:
- Tooth Count - Count carefully (all teeth must be present for accurate count)
- Overall Diameter - Measure across the gear
- Arbor Diameter - Measure the shaft (important for pivot holes)
- Arbor Length - Total length and any extended portions
- Pivot Diameters - Top and bottom pivot sizes
- Hub Thickness - How thick the gear center is
- Tooth Height - From root to tip
Visual Comparison:
Even with measurements, visual comparison using our detailed photographs often reveals compatibility:
- Does overall appearance match?
- Is tooth profile similar?
- Is construction style (collet, lantern pinion, etc.) the same?
- Does the era match your movement?
Movement Identification Helps:
If you can identify your clock's manufacturer and approximate era, it narrows possibilities significantly. Our photographs often show manufacturer characteristics visible in wheel construction.
The Pinion Relationship
The 2nd wheel works with the 2nd pinion (the small gear it meshes with):
Pinion Considerations:
- 2nd wheel meshes with great wheel pinion (1st pinion)
- 2nd wheel pinion meshes with 3rd wheel
- Both connections must have proper depth (how deep teeth engage)
- Replacing wheel sometimes reveals pinion wear
- Depthing (adjusting mesh depth) may be needed after replacement
Professional Installation:
While identifying and purchasing the correct clock gear replacement is something knowledgeable enthusiasts can do, installation often requires clockmaker expertise for:
- Proper depthing adjustment
- Pivot fitting to holes
- Arbor length adjustments if needed
- Motion works alignment
- Testing under power
Why Authentic Period Wheels Matter
Generic replacement clock gears rarely match antique movement specifications:
Manufacturing Differences:
- Modern reproductions may use different tooth profiles
- Brass alloy composition affects durability
- Machine cutting methods differ from historical production
- Dimensions may be "close" but not exact
Authentic Advantages:
- Original wheels match movement design perfectly
- Period-correct materials and construction
- Proven longevity (survived 50-150 years already)
- Maintains clock's historical authenticity
- Proper mesh with other original gears
Collector Value:
- Original components maintain clock's value
- All-original movements worth more than pieced-together repairs
- Historical integrity preserved
- Clockmaker's original design maintained
Historical Context: Clock Gear Manufacturing
Understanding how clock wheels were made helps appreciate variations:
Hand-Cut Era (Pre-1840s):
- Individual teeth filed by hand
- Slight variations between wheels
- Skilled craftsmanship required
- Each wheel somewhat unique
Early Machine Era (1840s-1870s):
- First gear-cutting machines
- More consistent but still variable
- Different manufacturers used different cutters
- Some standardization begins
Precision Manufacturing (1880s-1950s):
- Advanced gear cutting machinery
- Better consistency within manufacturer
- Still no universal standards between companies
- Peak of American clock manufacturing
Modern Production (1960s-Present):
- CNC precision for German movements
- High consistency and quality
- Metric standardization (European manufacturers)
- Limited manufacturers still producing
Common Problems After 2nd Wheel Replacement
Even with correct replacement clock gears, issues can arise:
Depthing Problems:
- New wheel may mesh too deep or too shallow
- Requires adjustment of plate spacing or pivot hole position
- Professional clockmaker can adjust depthing
Pivot Fitting:
- New wheel pivots may not match old pivot holes perfectly
- May require bushing holes or turning pivots
- Critical for smooth operation
Motion Works Alignment:
- Extended arbor must align properly with motion works
- Incorrect length affects hand operation
- May need adjustment or modification
Break-In Period:
- New wheel meshing with old pinion needs break-in
- Initial stiffness is normal
- Should smooth out after running under power
These issues underscore the value of professional installation for valuable clocks.
Caring for Clock Gears
Once you've replaced your time side 2nd wheel, proper care extends its life:
Proper Lubrication:
- Very light clock oil on pivots only
- Never oil gear teeth (dry operation is better)
- Over-oiling attracts dust and creates sludge
Regular Maintenance:
- Professional cleaning every 8-10 years
- Inspection for wear
- Oil refresh
- Removal of accumulated dust
Gentle Handling:
- Support arbors when removing or installing
- Don't force assemblies
- Protect teeth from impact
- Store removed wheels carefully
The Donor Clock Alternative (and Why It Often Fails)
Traditionally, finding a replacement 2nd wheel meant buying a complete donor movement and hoping the needed gear was intact.
Donor Movement Problems:
- Can't see inside before purchase
- Often donor has same failed component
- Expensive ($50-$300+ for complete movement)
