Assembly Procedure
The recommended and preferred method of assembly
is vertical with 2.775" stickup. There are (3) key build
variations that impact the assembly process. They are:
1. Vertical with 2.875" stickup, secured shaft
2. Vertical with 2.875" stickup, unsecured shaft
3. Horizontal assembly
Conditions related to these variances are:
• If using a fixture with stickup height of 2.775" , the shaft
SHOULD be secured.
• If the shaft is NOT secured, the "spacer washer"
method SHOULD be used for assembly of each stage.
Building with "Washers" at each stage is advised to
minimize the potential for shaft bounce (when striking
with collet driver), and also to allow for easier removal
of impeller if necessary.
4" or 6" Motor Assembly (Recommended: Vertical
