The four specific items required to purchase
the correct replacement spring(s).
|
- #1 Wire Size
- #2 Inside Diameter
- #3 Length of spring
- #4 Wind of spring (Right or left wound)
|
 WIRE
SIZE:A spring’s wire
size can be determined by several different tools or techniques. Use
of a caliper, micrometer, or wire gauge are common ways to determine
a spring’s wire size. If none of these tools are available, simply
measure ten coils of wire to the nearest 1/16th of an inch, and refer
to the Spring Wire Chart. The spring must be tightly compressed, with
no gaps. It’s also a good idea to measure twenty coils as a double
check.(Minumum order 6 springs)
|
 INSIDE
DIAMETER:Measure the inside
diameter to the nearest 1/16th of an inch.
The chart shows common ID’s used by various manufacturers.
If no manufacturers name is evident,measure the inside diameter:
134 or 175 = 1 3/4"
ID
258 or 263 = 2 5/8"
ID
375 or 334 = 3 3/4"
ID

LENGTH OF
SPRING:
Measure spring
length with the spring in its unwound state. In the case of a distorted
or broken spring, simply count the total number of coils and multiply
by the wire size.
120 coils x .250
wire = 30"
120 coils x .375
wire = 45"

RIGHT OR LEFT HAND WOUND:
To ensure the correct
wind, please refer to the Winding Chart below. Please remember the side of the door a spring is located on does not indicate the wind of the spring. |
