Installing a New Seal

Perform the procedure in Table 43, Figure 41 and Figure 42 to replace the barrel seal with a new seal. When installing a new seal, NEVER use oil or silicon based lubricants. This can cause the new seal to rotate and LEAK!

	Table 43
Step	Action
1	Remove the old seal and the spacer (see Table 42).
2	Remove the new seal from its packaging.
3	Clean the spacer.
4	Slide the spacer (with slots toward the motor housing) over the motor shaft.
5	Lubricate the inside of the seal using Dow Corning 111 Lubricant and Sealant.
	(Note, Do not lubricate the static side(outer portion) of the seal. This could
	cause the seal to rotate in the bore and leak.)
6	Carefully slide the seal over the motor shaft and press it firmly until is fully
	seated against the spacer and the seal cannot be pushed any further.
7	Run your finger around the perimeter of the seal to insure it is flush against the
	back of the barrel.
8	Reinstall the blade assembly. Rotate the assembly while inserting it to insure
	that it is fully seated on the motor shaft. (Figure 30)
9	Lubricate the faceplate o-ring.
10	Re-install the faceplate and replace the four (4) mounting nuts. Hand tighten
	the nuts until the faceplate makes contact with the gasket, then use a wrench
	to tighten the nuts an additional 1/4 turn. Be careful not to overtighten the nuts
	or cracking of the faceplate may result.
11	Clean the drip tray and tube using warm water.
12	Perform the seal leak test in Table 44.
