Assemble
end cover
17. Assemble end cover over the alignment
studs and onto the commutator set. SEE
FIGURE 53 & 54. If the end cover has only
5 bolt holes be sure the cover holes are
aligned with the 5 threaded holes in hous-
ing (17). The correct 5 bolt end cover bolt
hole relationship to housing port bosses is
shown in FIGURE 53. After June 2012, end
cover no longer has o-ring section seal.
NOTE
NOTE: If the end cover has a valve (22,
24) or has five bolt holes, use the line you
previously scribed on the cover to radi-
ally align the end cover into its original
position.
