Lowest Price GuaranteeAdjusting valve lash on rockers with set screw poly locks usually takes two hands and two tools fighting each other. With this set the 9/16 in. wrench goes over the lock nut and the T-handle Allen wrench drops through the hole in it, so one hand holds the adjuster while the other locks it down, cutting adjustment time roughly in half.
Proform 66780 Valve Lash Wrench Set Features:
- 9/16 in. wrench for the rocker arm lock nut
- 3/16 in. and 7/32 in. T-handle Allen wrenches for the set screw
- T-handle drops through the wrench for one-handed adjustment
- Plastic grips for comfort
- Stainless steel construction, natural finish
- Sold as a complete set
These simple T-handle and wrench sets make valve lash adjustments a breeze. Just choose the proper size for your application and you are ready to cut your adjusting time in half. Simply position the adjusting handle wrench over the rocker arm lock-down (make sure you have purchased the set with the proper sized wrench), and drop the appropriate T-handle down through the hole in the wrench - with one hand doing the job of two! Then make the lash adjustment with a feeler gauge according to the camshaft manufacturer's specifications.
