    Figure 2. Pushrod Installed into Pushrod Cover
  8. Insert the pushrod (within the pushrod tube) into the front cylinder head intake pushrod hole (hole closest to the cylinder) then slip the adjuster end of the pushrod into the tappet block.
  9. NOTE
    Pushrod adjustment must be made with engine cold.
  10. Adjust pushrods.
    1. Adjust pushrod length to zero clearance by hand.
    2. With the pushrod adjusting screw kept from rotating with a 5/16 in. wrench, slowly turn the pushrod tube with a 1/2 in. wrench, 2-1/2 complete turns clockwise (lengthening the pushrod) as viewed from the bottom. (There is a dot on the flats of the pushrod tube that can be used as a reference.)
    3. Hold adjusting screw and tighten locknut with 1/2 in. open end wrench against the pushrod tube. If pushrod turns with locknut use three open end wrenches, one to hold the pushrod tube, one to hold adjusting screw and one to turn locknut.
    4. Repeat steps 5 through step C for the exhaust pushrod.
    5. NOTE
      Wait ten minutes before turning engine over after adjusting front or rear cylinder pushrods. This wait allows tappets to bleed down and prevents bending pushrods or valves. Pushrods should turn freely and valves must be on their seats (closed) before turning over engine.
    6. Wait ten minutes. With transmission in gear, use rear wheel to turn engine over until both rear cylinder tappets are at their lowest position.
    7. Repeat steps 5 through step D for the rear cylinder.
