NOTICE
If backlash is above the specified limit, the gears are not necessarily unusable. Excessive play
could be caused by worn bearings.
5.
If timing gears appear to be reusable, match marktiming gear toothmesh by making small punch marks on
the ends of meshing gear teeth with a pin punch and hammer (see FIGURE 6-2, page 25). The impeller tip
to valley (throat) and the case to headplates should also be matchmarked to facilitate blower reassembly.
6.
Using a gear puller, remove timing gears. The taper pin should back out with the gear as the gear is being
removed (see FIGURE 6-3). Use caution not to damage gear teeth with puller if gears are to be used again.
NOTICE
Blowers with mechanical seals have two wavy washers (28) located between the bearings and the
cover on the drive end.
7.
Remove the socket head cap screws (30) from the drive end bearing cover (29) and remove the cover. Drive
shaft oil seal (31) should come free when cover is removed.
