HARLEY Jims Tappet Adjuster Tool Fits 1984-2017 FXST, 1984-UP FLT, 1986-2017 FLST, 1991-2017 F

Jims tappet adjuster hand tool verifies proper adjustment on most hydraulic tappets for Evolution and Twin Cam models. Tappet adjustment made easy! After adjusting the tappet simply insert the tip of this tool under the hydraulic unit retaining clip and above the pushrod seat. Similar to a inchGo/No-Go inch gauge if the tip does not fit between the clip and seat OR if there is up and down end play then the tappet is not properly adjusted. Only when the tip fits nicely with no end play is the tappet adjusted properly. FITS HARLEY: 1984-2017 FXST, 1984-UP FLT, 1986-2017 FLST, 1991-2017 FXD, 1984-1994 FXR, 1986-UP XL,
