phildirt Posted September 21, 2013 Share Posted September 21, 2013 Here are 3 scans from Mack publication 5-301 ID 89-Not as complicated as it seems- you can make the tool easily with a mill.Be sure that you have the fuel shut off off before you start barring the engine over.

gearhead204 Posted September 21, 2013 Share Posted September 21, 2013 just did mine, in place of the dynatard tool I was able to use a 1 1/4 wide gasket scraper to adjust and hold the barrel while setting the jam nut Quote Link to comment https://www.bigmacktrucks.com/topic/32853-valve-setting-procedures-for-e9-500/#findComment-207467 Share on other sites More sharing options...
MACKTRUCKS4 Posted September 21, 2013 Share Posted September 21, 2013 Make sure when you set the valves, you rotate the motor over twice, had a guy sets valves once and he only rotated once and set the valves for two cylinders on one mark. Needless to say, it did not run too well, but it did run. 1 Quote Live every day like it's your last, because one of these days, it will be.

rsb502 Posted September 24, 2013 Share Posted September 24, 2013 I just set mine this afternoon, I had a tick on the left and found two exhaust valves loose, it idles purty smooth now, I use a closed end wrench and a big flat head screwdriver for the exhaust, I just hold it in one side of the groove and it works you dont need a lot of torque.
