Hydraulic pushrods for Ingersoll-Rand engines

Filling and Bleeding Instructions for Ingersoll-Rand KVT (fuel) and Ingersoll-Rand KVR (fuel) engines

    1. Be sure the lifter units and barrels do not contain any foreign matter.
    2. Clamp the lifter upright in a vise below the outer tube on the bottom 2" of the pushrod.
    3. Remove the outer barrel and fill the pushrod with 10W - 40 oil.
    4. Insert the driver into the lower barrel slowly (to keep from displacing a little amount of oil as possible) and work it up and down to be sure the lifter unit is seated properly. Insert the bleed wire through the center of driver. Locate the ball check valve in the lifter unit. While holding down on the bleed, work the driver up and down to purge all the air out of the lifter unit. After removing the bleed wire, push down on the driver. If any downward movement is felt, repeat the bleeding process.
    5. CECO Magnum Hydraulic Pushrods should be inspected once a year. If the oil is contaminated, wash out the pushrod with a clean solvent. Replace with clean oil. Magnum units must be kept clean.

Installation and Adjustment

  1. Remove the existing pushrod from the engine. Check rocker arm bearings for correct clearance, Remove the spring under the fuel valve rocker arm if applicable & install the CECO Magnum pushrods.

    Note: If unit has OEM hydraulic lifters in rocker arm remove and replace with CECO spacers.

    Note: If unit has OEM hydraulic lifters in the pushrod of fuel valve. It will be necessary to replace the ball end with" like ball end" on intake and exhaust rocker arm. Remove the oil feed tubing line & fittings from the fuel rocker arm. Plug the top (1/4" NPT) hole with flat "Allen" head pipe plug. Drill a 1/32" hole in center of plug to allow oil to travel to the ball socket.

  2. With the #1 cylinder on TDC (Top Dead Center), and all valves are closed, screw down on the adjusting screw until it touches the valve. Now make 1-1/2 turns down and set the locknut. Proceed to the next cylinder, in firing order and repeat.
  3. Turn the engine over, with air or starter; to be sure all the pushrods hold their setting.
