Engine Crankcase Replacement
717 Engines
Since replacement crankcases do not have timing
mark for armature plate location, indexing marks
should be made on armature plate and crankcase
to ease reassembly and further ignition timing.
The following procedure is to find a common ref-
erence point on both crankcases (old and new) to
position armature plate.
Proceed as follows:
– Find a crankcase locating lug (the top one in this
example).
– Place a cold chisel at the end of chosen lug,
then punch a mark on armature plate at this
point.
1. Crankcase locating lug
2. Mark armature plate at the end of lug
– At assembly, align armature plate mark (previ-
ously punched) with the end of the same locat-
ing lug on the new crankcase.
