INTRODUCTION
Thank you for purchasing this CLARKE Coil Spring Compressor Set.
The CHT965 is suitable for most MacPherson strut coil springs. It features a yoke
extension bracket that also allows use on conical springs. It comes supplied with
three pairs of different sized interchangeable yokes for a wide range of vehicle
applications.
The plastic yoke protectors protect the spring coating from damage which could
invalidate the vehicle manufacturer’s guarantee. The safety yokes are carefully
shaped to stop the spring bowing while under compression.
Before attempting to use this product, please read this manual thoroughly and follow
the instructions carefully. In doing so you can look forward to your purchase giving
you long and satisfactory service.

BE COMPRESSED AND SELECT THE CORRECT SET OF YOKES TO FIT
THE SPRING.
• DO NOT operate the spring compressor if parts are damaged or missing as
this can cause failure or injury.
• DO NOT use air tools to operate the spring compressor.
• DO NOT allow persons unfamiliar with this product to operate the device.
• ALWAYS familiarise yourself with the applications, limitations and
potential hazards of the product.
• Maintain the spring compressor in good condition. Replace or repair any

dangerous and will invalidate the warranty.
• Keep the work area clean, uncluttered and ensure there is adequate
lighting.
• Keep hands and body clear of the spring when under compression.
• Maintain correct balance and footing. Ensure the floor is not slippery and
wear non-slip shoes.

INSTRUCTIONS FOR USE
WARNING: MEASURE THE OUTER DIAMETER OF THE SPRING TO BE
COMPRESSED AND SELECT THE CORRECT SET OF YOKES.
WARNING: ENSURE THAT THE COIL SPRING TO BE COMPRESSED IS
FREE FROM DIRT AND GREASE WHERE THE YOKES WILL BE IN
CONTACT WITH IT
1. If removing the coil spring directly from the vehicle, raise the vehicle and remove
wheels and any other items to allow access to the spring.
• Make sure that the vehicle is safely and correctly supported.
2. Measure the diameter of the ends of
the spring and select appropriately
sized yokes.
• A matching pair of yokes will suit a
parallel sided spring but for a
conical spring it may be necessary
to combine different sized yokes.
• Bolt your selected yokes to each
end of the compression device
using the connecting bolts
supplied. A key is provided for this.
3. Position one yoke under the lower
part of the spring winding.
4. Position the other yoke onto the top
spring coil.
• Install the yokes as close as
possible to the ends of the spring.
• Make sure that the spring coils sit
between the inner and outer rims
of the yokes.

5. Attach the body of the spring
compressor to the yokes using the
extension bracket if required, to align
the axis of the spring with the
compressor.
• Make sure that the spring is
correctly seated within both yokes
and the yokes are correctly
aligned with the compressor body.
• If necessary use the extension
block to keep the spring and compressor body parallel.
6. Use a 21mm hex socket to turn the hexagonal drive nut until the yokes are firmly
in contact with the spring.
7. Now continue tightening to compress the spring.
WARNING: AIR TOOLS MUST NOT BE USED TO ADJUST THE SPRING
COMPRESSOR. USE OF AIR TOOLS WILL INVALIDATE THE
WARRANTY.
WARNING: DO NOT ALLOW THE SPRING WINDINGS TO TOUCH. DO
NOT ALLOW THE COMPRESSOR TO REACH THE LIMIT OF ITS
TRAVEL IN EITHER DIRECTION.
8. Remove the compressed spring and compressor assembly from the vehicle once
you have attained sufficient compression.
9. With the spring supported turn the hexagonal drive nut in the opposite direction
and remove the compressor and yokes from the spring.
10. To re-mount the spring, reverse the procedure.
TO COMPRESS A STRUT SPRING REMOVED FROM A VEHICLE
1. Secure the strut with a clamp, vice or
other adequate holding device.
2. Mount the selected yokes on the
compressor body, fit the retaining
bolts and tighten securely.
3. Rotate the hexagonal nut to drive the
jaws apart to the length of the spring
and to allow compression of as many
windings as possible.
4. Position the spring strut compressor
onto the spring, ensuring the spring seats correctly between the lips and the outer
rib and cannot slide out during compression.

rotate.
