Assembly
(See Figure 6-3 for reference numbers.)
Assembly is in reverse order of disassembly with the
following additional instructions.
1. Lubricate the sealing lip of the oil seal (4) with the same
type of hydraulic oil that the crane uses. Press the oil
seal into the brake housing (3) with the open side of the
seal facing the hydraulic motor end of the brake
assembly. Install the bearing (5) into the brake housing.
2. If replacing the dynamic brake o-rings (7 and 8), be sure
to install the o-rings and their backup rings (6 and 9) in
the same order in which they were removed. Lubricate
with hydraulic oil to aid assembly.
