Hydraulic valve adjustment
· Warm up the motor.
 | Take one valve cover off, start motor and begin at one end and back off a polylock slowly until it the lifter starts to make noise. |
| With your fingers (can use a socket w/o ratchet to make it easier to turn) leaving the setscrew loose start to tighten the polylock until it is quiet, you will feel the polylock just hit resistance. |
| Then back it off a little until it starts to make noise again, repeat this step until the polylock quiets the lifter at the same place with the polylock. |
| Take your allen wrench and regular wrench hold the polylock and spin down the setscrew until it just snug against the rocker stud. |
| Now holding BOTH the allen and regular wrench together tighten them 1/8th to ¼ of a turn. |
| Move to the next polylock. |
