Jims standard hydraulic tappet has an outer diameter of .731 . Tappets are without internals. Order hydraulic unit separately. **NOTE: Tappet adjustment will make the pushrod tight. Wait 5-15 minutes or longer to fully bleed off the hydraulic tappet. Make sure engine is not rotated while pushrods are tight. Pushrod will spin with your fingers after the tappet has bled off. Never turn engine over if the pushrods will not spin with your fingers after adjustments were made.
