HYDRAULIC TAPPET

Removal
Take the hydraulic tappets out and place them
into an oil-filled vessel to prevent the hydraulic
tappet oil from leaking out.
Check the top and bottom contact surfaces of
the hydraulic tappet to observe whether there
are abnormal abrasion or scrapes. If yes,
replace it with new one if necessary.
Installation
Apply hyperbolic gear oil or motor oil on the
tappet and external diameter as well as its two
ends and place the tappet into the cylinder
head hole in the original order.
