Clean the output shaft and slide the case halves
off. Remove the seals from the case halves and
discard the seals.
9.
Returning to the impeller shaft, the 824XL models
have a worm that is actually rolled into the impeller
shaft. All other models use an individually
replaceable gear. Remove all the bushings,
bearings and spacers from the impeller shaft
(Figure 26).
Clean and inspect the bushings in the case
halves. If they are damaged or worn, press them
out of the case halves at this time.
10.
Now inspect the worm and worm gear. If either
gear is damaged, replace them both. When gears
run together, they develop wear patterns unique to
the two of them. Replacing only one gear will
result in early failure.
Slide the worm gear off the shaft. Depending on
the model, there will be one or two woodruff keys
between the gear and the shaft. Refer to the parts
manual for your specific machine.
