1986 Mack 4 valve and dynatard


Recommended Posts

Hi guys, I have a 1986 Mack RD dump that I just picked up and I am looking at my Mack book on how to adjust the dynatard 4 valve engine. I have no problem following the instructions other than is it required to use the SPECIAL tool as shown in book to loosen the lock nut on the hydraulic side. The tool is not available and I don't believe it is a must have. Book explaind to use special tool to loosen locknut and back out adjuster then using feeler gauge on yoke side adjust the yoke while holding pressure down using .010 feeler. Seems like the tool is not required. I have adjusted many 2 valve mack engines with dynatard cam but this is first 4 valve
