Small Engines (Lawn Mowers, etc.): Kawasaki FH500V pushrod, hydraulic lifter, hydraulic lifters

Question
Hi,

 My Gravely 44" z-turn has a Kaw FH500V engine.  On occasion, when I start it it develops almost no power and clacks loudly. I have traced the problem to one pushrod that just drops out of place.  To correct it I put the pushrod back into the depression on the rocker and all is well..sometimes for months.  Sometimes I have to put my finger on the rocker to keep it in place while the engine idles to wait for the lifter to pump up.
 I imagine I have a bad lifter.  Any fixes?  If I have to put in a new lifter what is involved?

Thanks!!

Answer
HI MIKE

FH500V   CAN YOU LET ME KNOW THE OTHER NUMBERS FROM ENGINE IE  AS07  ETC

NEED THESE TO IDENTIFY ENGINE

I SUSPECT MODEL IS SOLID CAM FOLLOWER NOT  HYDRAULIC LIFTER BUT MAY BE WRONG ?

IF ENGINE HAS SOLID LIFTERS - ENGINE WOULD NEED TO BE REMOVED FROM CHASSIS - PUSH RODS REMOVED
OIL DRAINED , AND C/CASE COVER PLATE REMOVED ,  AND CAM SHAFT REMOVED
THEN REPLACE  ALL FOLLOWERS AS A SET AND MAKE SURE  DECOMPRESSOR SPRING ON CAM SHAFT WAS WORKING
CHECK THE  PUSH RODS FOR BEND

BUT IF YOU ENGINE DID HAVE HYDRAULIC LIFTERS  - YOU WOULD SIMPLY REMOVE ROCKERS AND PUSH RODS AND AND USE A VALVE LIFTER REMOVAL TOOL TO REMOVE  LIFTERS FROM THE  TOP


BUT 1ST LET ME KNOW NUMBERS OFF ENGINE  
AND I WILL LET YOU KNOW
