How to adjust exhaust valves on 90 E-7 350 Mack Engine with Dynatard exhaust brakes

there are yokes to put under the rocker arm to set lash.  The thickness is based on the type of turbo you have, I have made these adjustments using feeler gauges.  I check both sides to be sure that the lash is correct. I have several individual feelers that I have riveted together for the different engines I do. so I use these paired feelers to get it done. If you need to know the lash setting, there is a chart that uses the turbo series.  ie: s-300, or s-400 turbo's and so-on..  not a big deal..  there are people here that can tell you off the top of their heads... I have a Mack book that has all of the specs... Jojo
