Zenoah K114283110 5x10x1.6mm Spacer Washer for Zenoah Engines  [K114283110]

Installation Spacer for Zenoah Engines

This Zenoah K114283110 spacer washer is a precision 5x10x1.6mm component intended as a direct replacement in Zenoah engine assemblies. It is specified for use where exact axial spacing is required on engine shafts and related mounting points in model setups.

Compatibility is limited to the models named by the manufacturer, specifically G200PU-EI, 260PU, and G231-290PUM as listed on the part label. Fit this part only when your engine's parts list or exploded view shows the same part number and dimensions to ensure correct installation.

Installation and tuning role

• Function: Provides controlled axial spacing to reduce endplay and maintain alignment between shaft components and couplings during operation.
• Installation: Slide the washer onto the shaft or bolt exactly as shown in the engine or gearbox assembly instructions, verify orientation, and confirm clearance before final tightening.
• Tuning impact: Small changes in spacer thickness alter shaft-to-housing clearance and coupling alignment; change one washer at a time and check for binding or increased play.

Practical tips

• Handle as a precision part; keep it free of grit and old threadlocker when reassembling.
• Verify the 5x10x1.6mm dimension against the mating shaft and bore before reuse to avoid unintended wear.
• Store with other small spares in labelled containers to prevent mix-ups during repairs or trackside work.
