ASSEMBLY WITHOUT ASSEMBLY TOOLS
a) It is recommended that assembly tools be used to assemble the actuator. Assembly tools
simplify assembly and significantly reduce the likelihood of damaging critical parts and
features during assembly.
b) It is possible to assemble the actuator without assembly tools when extreme care and patience
is taken and combined with the fabrication of simple wood supports.
c) The previous sections
Evaluation and Corrections
along with
Preparation and Seal
Installation
outline part inspection, preparation, and assembly steps and
MUST
be followed
before proceeding to the next step.
d) Fabricate Support Blocks:
i) It is recommended to use wood to fabricate the support blocks.
(1) A hardwood will prove more durable.
ii) Block Dimensions
(1) Reference the drawing of the support block sizing.
(a) Note: The dimensions specified are based on assembling the actuator on a flat
surface without a hole in the table.
(2)
Alternatively
, the block can be match sized using the shaft.
(a) Place the shaft on its end standing upright on a flat surface, scribe/mark onto the
blocking material the heigh corresponding to the bottom portion of the vane face.
Reference the
Alternative
image below.
iii) The height specified in the diagram and identified as a
**CRITICAL DIMENSION**
is
important. However, the use of shim stock or a small, tapered wedge can be used to
compensate for any deviations. This is explained in a following step.
iv) A total of two (2) support blocks are required.
e) Body Orientation:
i) Place the each of the wood blocks onto a clean
flat work surface.
ii) Place the body on top of the wood blocks
oriented as identified.
iii) Take note of the two dowel hole positions
nearest the manifold mounting face to
determine proper orientation.
