6.3 Spider Removal and Installation
See Graphic: wc_gr003422
Removal:
6.3.1 Remove the gearbox(es) from the machine. See section Gearbox
Removal and Installation.
6.3.2 Remove the screws that secure the blades to the arms and remove the
blades
The blades may have sharp edges that can cut. Wear an appropriate
pair of gloves when removing the blades.
6.3.3 On machines with stabilizer rings, remove the shoulder bolts from the
ends of the arms and remove the stabilizer rings (a).
6.3.4 Remove the shoulder bolts (b) from the lift ring assembly. Do not
change the position (rotate) of the lifting links (c) unless readjustment
is being done.
6.3.5 There are two styles of arms used. One style uses a locking pin to
retain the arm to the spider. This style is characterized by the hex nut
(d) into which the grease fitting is installed. If your trowel has this style
arm, remove the locking pin (with the grease fitting). On styles with just
the grease fitting (e), the grease fitting may be left in place.
6.3.6 Remove the cotter pin (f), the pivot pin (g), and the blade yoke (h) from
the machine. Remove the roller guides (i) if necessary.
6.3.7 Remove the plug (j) from the spider. Remove the bolt (k) and washer
(l) and remove spider (m) from the gearbox.
6.3.8 Remove the lift ring assembly (n).
6.3.9 Repeat these steps for the opposite gearbox.
