Clark forklifts running a Mitsubishi 4G54 engine use ignition tune-up kit 1811585. If your Clark is idling rough or hesitating under load, this is usually the first thing to check before chasing anything more complicated.
Signs your 4G54 needs a tune-up
- Rough or uneven idle
- Hesitation or misfire when accelerating
- Hard starting
- Falling fuel economy despite normal use
Compatibility
This kit is built for Clark forklifts powered by the Mitsubishi 4G54 engine. Confirm your engine tag before ordering — Clark used multiple engine suppliers over the years and the wrong kit won't match your ignition components.
What's included
The 1811585 kit bundles the ignition parts needed for a complete tune-up on the 4G54, saving you from sourcing components individually.
Installation overview
Replace ignition components one at a time to keep wire routing correct. Gap and torque new parts to Mitsubishi spec, then start the engine and confirm the idle has smoothed out before closing up the engine bay.
