Dieselpower170 Posted June 27, 2019 Author Share Posted June 27, 2019 Rob, it does have the dynatard on it, If I can actually do it without the tool, I’d try it, but if I could see the procedure that would be awesome!

fjh Posted June 28, 2019 Share Posted June 28, 2019 (edited) AI use my thumb loosen the jam nut turn the adjuster in till it won’t move the with a screw driver or your thumb back it out one half turn then place your blade under the rocker turn the adjuster in till you got drag on the feeler then lock it with your 11/8 wrench and check the feel it can change as you tighten the jam nut! Adjust as nessary to get the right drag on the blade Edited June 28, 2019 by fjh Quote Link to comment https://www.bigmacktrucks.com/topic/57863-865-valve-adjustment/#findComment-426268 Share on other sites More sharing options...

I’m lookin for what I should be setting the valves at Setting the valve lash is the same as an E9 except you do not have set the bridge first. There is no bridge on a 2 valve ENDT865. Lash clearances is listed on the valve cover tag. Got both engines and set valves real EZ as long as you can bar the the engine over, both with Dynatard. Don't worry if the Tard does not work, it is useless anyway on both engines. By the way the E9 head gasket will not work on the ENDT865/866 series engines, Different bore and fire ring diameter. 865 gaskets are still available at least in Australia I am told from Mack. END864 is totally different as well. Quote Link to comment https://www.bigmacktrucks.com/topic/57863-865-valve-adjustment/#findComment-426274 Share on other sites More sharing options...
