The Clutch Spring Height tool is used to accurately set the spring heights on your disk style clutch with vertical springs. Once the tool is zeroed out, simply slide the adaptor over the clutch spring until the base rests on the back of the clutch. Make a note of that measurement and then check the remaining springs. Your clutch manufacturer or blue printer can tell you what this height should be for your class. This standard tool fits Hortsman, Tomar, Stingers and most other brands with a screw style adjustment and small diameter springs.
We now offer the our clutch spring tool with an Anodized Purple adaptor at no extra cost.

HDM also manufactures a clutch spring height tool specifically for the Buller - Bully Clutch. The bully uses a stud and nut style spring retainer so the standard tool will not work. This Bully tool has a special indicator tip so the spring height can be read from the flange on the adjusting nut. The reason we read on the flange is due to the fact that the hex part of the nut can become damaged and burred on top causing inaccurate readings. (clutch is not included in price)

The Laser Sprocket Alignment tool is very easy to use. With the chain removed from the clutch driver and rear sprocket, simply slide the alignment tool down over the rear sprocket. Now rotate it until it looks to be pointing at the clutch driver. Push the button to ignite the laser. You can either adjust your motor mount (if it has side-to-side adjustment) or your sprocket hub so that the red dot from the laser hits directly on the clutch driver.
The alignment calibration is preset at the factory before shipping. Anytime you need it recalibrated, simply send back to HDM and we will be glad to do recalibration of your tool for free (customer must pay shipping cost both ways). Call or email for Return Good Authorization number.
Our sprocket alignment tool is now available with Purple Anodizing at no extra cost.
