Install the motor thrust bearing into the housing.
NOTE: It will be necessary to have a DRY journal bearing
to prevent a hydraulic lock while installing the motor shaft.
Install the motor shaft/cylinder block kit. Use caution to
prevent damage to the journal bearing while guiding the
shaft into position. Once installed, it will be necessary to
hold the assembly in position until the center section has
been installed.

BDU-10 with Pump Block Installed
Assembly Procedure
NOTE: To simplify the installation of both the motor block
and the pump block kits, wrap a rubber band snuggly
around the pistons. This is intended to hold the pistons in
their bores as the block kits are handled during installation.
With the swashplate in the “neutral” (0 angle) position and
the transmission housing laying on its side, install the
pump cylinder block kit onto the pump shaft in the housing.
