18. Note orientation of parts on gearbox shaft, and remove shell (with speed sensor cam
attached), grease adjuster, and spacer ring from shaft.
19. Working through two effluent ports at the liquid end, remove two M12 screws 180° apart from
the conveyor. Install two plates over the ports (Figure 5037-5), insert a long M12 screw
through each plate, and lightly tighten screws. These plates will retain the conveyor in place
while the gearbox is extracted from the bowl assembly.
20. Remove two pipe plugs from conveyor (Figure 5037-6), and drive out dowel pin securing the
gearbox shaft to the conveyor.
21. Remove 20 M16 socket head screws securing gearbox to bowl assembly (Figure 5037-7).
22. Remove four hex head M16 bolts from housing, and lubricate and install jack bolts in two of
the threaded holes 180 degrees apart.
23. Attach a suitable hoist capable of lifting at least 550 lbs (250 kg) to support gearbox as it is
jacked out of bowl assembly.
24. Alternately turn each jack bolt installed in step 22, above, to slowly draw gearbox out until fully
clear of bowl assembly.
