4. Lubricating Grooves − Dress
CAUTION
Damage Hazard: Make sure that you keep the initial shape of the
lubricating grooves when you remove sharp edges.
1) If the depth of the lubricating grooves (1, Fig. 2 ) has decreased to less than
1.0 mm, do as follows:
a) Use emery cloth or an oil stone to get the the lubricating grooves back to their
initial depth.
5. Scavenge Ports − Dress
CAUTION
Damage Hazard: When you polish the scavenge ports, make sure
that you do not cause damage to the running surface of the
cylinder liner.
Note: The scavenge ports (1, Fig. 2) are as seen in new cylinder liners.
1) Use emery cloth to polish the surfaces of the scavenge ports. Make sure that you
keep the shape of the scavenge ports the same as those shown.
2) After the repair is completed, fully clean the lubricating grooves and the bore of
the cylinder liner.
3) Remove unwanted particles, which may have passed into the scavenge space
through the ports.
4) Manually operate the cylinder lubrication until oil flows from all the lubricating
points. This will flush away unwanted metal dust.
