Checking The Play Of The Roller Arm And Replacing Bushings - McConnel ROBO-CHIPPER ROBOCUT Operations & Parts Manual

ROBOCUT ROBO-CHIPPER
To remove blades, loosen bolts (A) using
a 17mm wrench. Remove the blades
and sharpen; ensure the dimensional
figures stated in the blade illustration
shown below are respected. Replace the
blade (B) ensuring it rests against the
stop (C) and that the surface on which it
rests is perfectly clean. Tighten the bolts
(A) to a torque setting of 73Nm. If the
bolts (A) appear worn, replace them with
bolts of the same resistance class, 10.9
or higher.
When replacing parts, only original
spares should be used (marked with the
name of the manufacturer) and which are
readily available from the manufacturer.
If the blades have been subjected to
severe shocks or blows ask an expert to
examine them.
If blades are worn beyond the minimum
dimension shown opposite the blades
must be replaced immediately.
9.3.3 – CHECKING THE PLAY OF
THE ROLLER ARM AND REPLACING
BUSHINGS
Unhook the control rod handle (A) from
the spring clevis (B), remove the pump
guard (D) by unscrewing the four bolts
and unhook the spring (E). By applying
force by hand, check if the roller arm has
any axial or radial play that could lead to
the roller coming into contact with the
body of the machine.
If it does, the two bushings should be
replaced. Unscrew the bolt (F) at the end
of the joint and the 4 bolts (G) that fasten
it to the arm, withdraw it and remove the
two worn bushings.
Replace the bushings and put back
everything following a reversal of the
removal procedure.
When replacing the bushings, it is
recommended that a press is used to
insert them.
