7. Inspection:
• Inspect the guillotine for signs of damage. Replace
guillotine if
damage is found. Inspect the cylinder
and piston for damage if guillotine is damaged.
• Inspect the spring. Replace if rusted, damaged, or
ben
t.
• Inspect bellows. Replace if damaged or
ex
cessively worn.
• Submerse the assembly in parts cleaner.
Thor
oughly flush the EV housing base, bellows,
and mating surfaces. Verify no carbon is in the gas
transfer ports.
• Clean the guillotine with brake cleaner and a piece
of
fine steel wool. Clean only to remove hardened
carbon deposits.
8. Once clean, rinse blade with mild detergent and
water. Dry
completely.
9. Inspect the VES gas ports on the cyli
nder(s) for
blockage. Remove the spark plugs and use a piston
inspection light to illuminate the port(s).
10. Light must be seen through the VES gas port(s). If a
p
ort appears to be blocked, use compressed air or a
long .075" drill bit to clean the port.
NOTE: Do not drill hole marked: “X”.
NOTE: The transfer port diameter starts at 5mm and
th
en tapers to 2mm as it approaches the cylinder wall.
Do not damage taper and/or 2mm bore with a larger
drill bit.
11. Install a new gasket, then reins
tall the EV assembly.
Apply Loctite® 242™ to the fastener threads, and
torque to specification.
Rotate the crankshaft to move piston(s) to BDC-below
VES gas ports. Do not damage pistons when using drill
bit to clean ports.
