PROCEDURE FOR THE 5/8 INCH WIDE
SPRING
1. Place a piece of sleeving around each bolt.
2. Insert bolts thru the leaf spring. The leaf spring is
flat so the orientation of the leaf spring does not
matter.
3. Place the steel pressure pad in the housing with
the 1/8 inch wide standoff facing up. See Figure
F.19.
Figure F.19 - Housing and Pressure Pad for 5/8"
Wide leaf spring.
4. Insert bolts and leaf spring into plastic housing
being sure that the steel pressure pad remains in
position. Pressing on the bolt heads should pro-
duce a rocking action of the spring in it's housing.
5. Insert clamp assembly thru heat sinks. Install nuts.
Tighten clamp nuts equally on bolts until finger
tight. Be sure that the leaf spring is not cocked in
the housing. See Figure F.20. Heat sinks may not
be exactly as pictured.
6. Re-inspect the SCR for proper seating.
