Frequently Asked Questions
Which valve-adjuster sizes are covered by tappet tool set 35-4200?
The six-piece set covers 8mm, 9mm and 10mm adjuster locknuts and includes slotted, 3mm-square and 4mm-square tips for the adjusting screws.
How is valve clearance held while tightening the locknut?
Hold the adjuster screw stationary with the correct tip while tightening the locknut, then recheck the feeler-gauge drag because the setting can move as the nut is torqued.
Does the tappet tool fit shim-under-bucket valve trains?
No. It is for screw-and-locknut tappet adjusters with the listed tip and locknut sizes, not shim-under-bucket systems that use a different service method.
