22. Adjusting the Reamer
Adjusting the Reamer
Important
Before operating, switch off the installation
TOOLS REQUIRED:
•
1 engineer’s wedge set, 1 Allen key, 1 screwdriver, 1 extending ratchet handle, 1 bushing size 22
• Place the reamer opposite the inspection hole
• Select the largest tooth on the reamer using a set
of engineer’s wedges, turning them one after ano-
ther perpendicular to the cylinder.( c )
• Loosen the screw ( v )
• Position the selected tooth ( d ) perpendicular to the
cylinder
• Manoeuvre the reamer axis ( a ) placing the screwdriver
in one of the slots ( e ) turning in a
clockwise
direc-
tion to distance the reamer tooth from the cylinder
• Manoeuvre the reamer axis ( a ) placing the screwdriver
in one of the slots ( e ) turning in an
anti-clockwise
direction to bring the reamer tooth towards the cylinder
• Take a wedge equal to or less than 0.4mm and place
it between the tooth and the cylinder.
• Manoeuvre the reamer axis ( a ) placing the screwdriver
in one of the slots until there is contact between the
tooth/wedge/cylinder
• Isolate this adjustment by locking the screw ( v ) while
maintaining the axis ( a ) with a screwdriver in one
of the slots
• Remove the wedge by turning the reamer on itself
• To adjust the lower section of the reamer, fi rstly loo-
sen the hexagonal cap screw, positioned under the
arm locking he reamer axis
• Repeat the same procedure on the top section,
bearing in mind that the slots ( e ) are replaced with
pins ( g )
which can be moved using your fi ngers
• The only difference is that turning the pins in a
clockwise
direction brings the tooth closer to the
cylinder and turning in an
anti-clockwise
direction
distances
it.
• Tighten the hexagonal cap screw to lock the reamer
axis once the adjustment is completed
