JIMS Tappet Adjustment Tool

Tappet adjustments made easy by Hiro Koiso. This patent pending hand tool simplifies the way to verify proper tappet adjustment. After adjusting the tappet, simply insert the tip of this tool under the hydraulic unit retaining clip, above the pushrod seat. Similar to a “Go No-Go Gauge,” if the tip doesn’t fit between the clip and the pushrod seat or if there is up and down end play, then the tappet is out of adjustment. Only when the tip fits nicely with no end play is the tappet properly adjusted.

Use on most hydraulic tappets, O.E.M. and aftermarket, for Twin Cam or Evo
