ASSEMBLY - Continued
Install new drive pin (Figure 12, Item 2), if removed, into commutator (Figure 12, Item 1) drive pin hole until it
DO NOT force commutator into bore. It is a close slip fit and must rotate. Failure to follow this
caution may result in damage to equipment.
Install commutator (Figure 12, Item 1) assembly into housing (Figure 12, Item 4) commutator bore.
Commutator must not be cocked as it enters the bore. Drive pin (Figure 12, Item 2) must be in line with coupling
shaft (Figure 12, Item 3) drive pin slot indicated by timing mark. Engage drive pin end that protrudes from
commutator into coupling shaft drive pin slot, rotating coupling shaft if necessary. Commutator will be below
housing wear plate surface when correctly seated.
Commutator drive pin and coupling shaft drive pin slot at this point in the assembly are visible
through commutator center cavity for coupling pin engagement purposes.
Install either end of drive link (Figure 12, Item 5) through commutator (Figure 12, Item 1) cavity and engage
lower drive link spines into mesh with internal spines in coupling shaft (Figure 12, Item 3). A spline valley on
both ends of the drive link will now be in line with commutator drive pin (Figure 12, Item 2) and the timing mark.
