6.Clean the output shaft and slide the case halves off. Remove the seals from the case halves and discard the seals.

7.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.

8.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.

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).

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.
