Zenoah K114283110 Precision Shaft Spacer 5x10x1.6mm  [K114283110]

Tuning: Clearance and Alignment Effects

The Zenoah K114283110 spacer washer is a 5x10x1.6mm precision shim that changes axial spacing on engine shafts and mounting points. It is commonly used in tuning and setup to fine tune shaft alignment and coupling engagement in model engines.

Compatibility is limited to the models named by the manufacturer, specifically G200PU-EI, 260PU, and G231-290PUM as listed on the part label. Only use this part where documentation lists the same part number and dimensions to maintain predictable performance.

Installation and tuning role

• Function: Alters axial position to influence coupling alignment and reduce driveline vibration when tuned properly.
• Installation: Install the washer on the shaft or bolt per service instructions and check rotating clearance during a slow spin test before final assembly.
• Tuning impact: Small spacer swaps can change shaft timing contact and balance; make incremental changes and observe vibration, temperatures, and throttle response.

Practical tips

• Keep the washer clean and free from threadlocker residue to preserve fit and prevent binding.
• Double-check the 5x10x1.6mm sizing against the mating parts to avoid unintended misalignment.
• Carry spare labelled washers to quickly restore previous setups when testing different spacers on the bench or track.
