Engine Removal - Toro Workman HDX Auto Service Manual

NOTE: When removing the engine from the machine,
it is recommended to leave the transmission and span-
ner plate attached to the machine. This will allow easier
alignment of the engine and the transmission when the
engine is installed back into the machine. Alignment of
the engine and the transmission is critical for proper
drive system operation.
