Been up since 11 pm last nite Ya it ain’t rocket science it just needs a little space ! Same on the aux shaft!the E6 was a simple robust engine except for the lifters! I like it’s bolt on cam gear ! Wish they had kept that concept! I was kinda pissed when they changed to the press on set up! Knowing all the trouble they had with lifters why change?That said they were evolving the block toward or for the eteck at that time! 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552003 Share on other sites More sharing options...
RS Disposal Posted May 18 Author Share Posted May 18 Book says to heat vibration dampener for 13 minute in 250 degree oil. That I do not have access to. Is there something a little simple for me to do? And I agree about the camshaft gear. My son said he might of been able to get a small oven that they use at his work to heat bearings for the big pumps his company rebuilds.

Was able to get it on far enough with some light tapping with a brass hammer far enough for the bolt to engage the threads and pull it on the rest of the way 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552033 Share on other sites More sharing options...

Everybody has been so helpful in my quest and with my learning curve since my breakdown last fall that started my journey. I know there must be some older mechanics in my area who would know this stuff, but when I was first making inquiries into having a shop do the repair the attitude I got was that nobody really wanted to work on a 40 yr old truck. Probably because it wasn't sitting in their shop taking up space and knowing that sourcing some parts might be time consuming 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552036 Share on other sites More sharing options...

With the heating of the dampener with the heat gun before it didn't take much to get the dampener on far enough to engage the bolt 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552042 Share on other sites More sharing options...
mechohaulic Posted May 19 Share Posted May 19 in frame would explain no rear crank seal /ring . save the lead seal ; might need it down the road or change over to newer rear housing using lip seal and wear ring. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552043 Share on other sites More sharing options...

Joey Mack Posted May 19 Share Posted May 19 R.S,,, I can say that this group of guys is always ready to help. As far as the old parts, I would keep them, even if they are obsolite. You may be able to help someone out because you have the part. As far as old tools... I have a bunch of old tools.. Some were my Grandfathers tools, and some ( that I still use) were tools that my Mentor gave me or showed me how to make and use, and recently aquired some tools from a friend, that are still in boxes, and I know where they are when I need them. My pride for what I have learned about Mack trucks, and other trucks, as well as the people who helped me, are the reasons why I will never get rid of them, until my days are numbered and I can pass them on.. I always believed that what we do as truckers and truck mechanics is a brotherhood. We need each other.. best of luck with the Old Girl, she'll be up and running soon. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552048 Share on other sites More sharing options...

I am definitely keeping all my old parts. It's kinda a thing with me that the wife doesn't understand. And I definitely agree that it is a brotherhood. I drove truck western states for 15 years before I took over full time my dad's garbage trk business and his trucks. Started helping him 63 yrs ago and as much as I could when I was OTR. Took over full time when he got off the trk at 83 yrs old and been doing it now for 30 yrs. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552058 Share on other sites More sharing options...

RS Disposal Posted May 25 Author Share Posted May 25 Valve lash question. This engine has the dynatard so it has the hydraulic exhaust valve lash adjuster. Book say you need a special tool to adjust this. When I adjusted the lash back when the head was rebuilt, I just made sure I was pressing down on the adjuster as I was taking my measurement. Is there a different/better way I should be doing this or just making sure the adjuster has downward pressure on it while taking the measurement work?

Your doing it right! just make sure when you pull the feeler out after the jam nut is tight the feeler is snug but moves freely with very little resistance ! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74123-1979-endt-675-camshaft/page/4/#findComment-552514 Share on other sites More sharing options...
