SECTION 3 - CHASSIS & TURNTABLE
3-46 – JLG Lift – 3121259
NOTE: It may be necessary to turn one alignment stud out of the
housing (18) temporarily to assemble rotor set (8) or mani-
fold (7) over the drive link.
NOTE: If necessary, go to the appropriate, "Rotor Set Component
Assembly Procedure."
NOTE: The rotor set rotor counterbore side must be down against
wear plate for drive link clearance and to maintain the
original rotor-drive link spline contact. A rotor set without
a counterbore and that was not etched before disassembly
can be reinstalled using the drive link spline pattern on the
rotor splines if apparent, to determine which side was
down. The rotor set seal ring groove faces toward the wear
plate (9).
14. Apply clean grease to a new seal ring (4) and assemble it
in the seal ring groove in the rotor set contact side of
manifold (7).
NOTE: The manifold (7) is made up of several plates bonded
together permanently to form an integral component. The
manifold surface that must contact the rotor set has it’s
series of irregular shaped cavities on the largest circumfer-
ence or circle around the inside diameter. The polished
impression left on the manifold by the rotor set is another
indication of which surface must contact the rotor set.
15. Assemble the manifold (7) over the alignment studs and
drive link (10) and onto the rotor set. Be sure the correct
manifold surface is against the rotor set.
16. Apply grease to a new seal ring (4) and insert it in the
seal ring groove exposed on the manifold.
17. Assemble the commutator ring (6) over alignment studs
onto the manifold.
