Filling
and Bleeding Instructions for KVT, KVR (Intake & Exhaust)
Engines
- Be sure
the pushrod units and barrels do not contain any foreign matter.
- Clamp
the lifter upright in a vise below the outer tube on the bottom
2" of the pushrod.
- Remove
the inner barrel and fill the exhaust & intake pushrod
with 10W-40 oil.
- SLOWLY
insert the driver (inner barrel) into the pushrod and work
it up & down to be sure the lifter is seated and the driver
returns each time. (NOTE: The lifter will feel spongy at this
point.) Insert the bleed wire into the center hole of the
driver until wire comes in contact with the ball check in
the lifter unit. While holding down on the bleed wire, push
the driver down until it stops, then release, do this several
times to purge the air from lifter unit. After removing the
bleed wire, push down on the driver, if any downward movement
is felt, repeat the bleeding process. If special oil is needed,
contact a CECO Sales Representative for further instructions.
IMPORTANT: ALL AIR "MUST" BE PURGED OUT OF LIFTER
BEFORE INSTALLATION.
- 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 of Power Valves
- Remove the
existing pushrod from the engine. Check rocker arm bushing for
correct clearance.
- If the engine
design has (2) exhaust or intake valves, remove the spring under
the bridge.
- If unit has
OEM hydraulic lifters, remove and replace with CECO spacers.
- IMPORTANT:
ADJUST THE BRIDGE, BY BACKING OFF THE BRIDGE ADJUSTING SCREW,
HOLD DOWN ON THE BRIDGE AGAINST THE VALVE STEM AND TURN THE ADJUSTING
SCREW DOWN UNTIL IT MAKES CONTACT WITH THE VALVE STEM. MAKING
SURE THAT CONTACT ON THE EACH VALVE STEM ARE ALIKE.
- With the
#1 cylinder on TDC (Top Dead Center), and all valves are closed,
screw down on the adjusting screw until it touches the top bridge.
Now make 1-1/2 turns down and set the locknut. Proceed to the
next cylinder, in firing order and repeat.
- Turn the
engine over, with air or starter, to be sure all the pushrods
hold their setting.
