PLM pumps on the 4 valve kinda sucked too. APE pump was much better 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/53/#findComment-572700 Share on other sites More sharing options...
Vladislav Posted Thursday at 06:51 PM Share Posted Thursday at 06:51 PM 20 hours ago, Joey Mack said: I think the E-6 4 Valve came out in 1987. And then in 89-90 the E-7 was born... E6-4V came into production in 1985 if I'm not wrong. And many were equipped with Ambac pumps, Robert Bosch took place closer to 89. Trucks with E6-350 4V were 688 trucks - R688, MR688 etc. Trucks with generally similar EM6-300 4V were 690 trucks - R690, DM690 and so on. 2 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/53/#findComment-572730 Share on other sites More sharing options...

I thought they would be more compatible, but they were not that E6 was a running son of a bitch. Well, I finished the velvet adjustment. I was gonna set the timing, but I figured that’s enough for the day. It’s a lousy day with no sun. Ok, no sun - no timing 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/53/#findComment-572732 Share on other sites More sharing options...

Attached a can of fuel higher than the pump inlet. So the stream was forced by gravity. Very sharp way of setting, a pump shop calibrates plungers that way. But care and attention is needed when removing the delivery valve. And sure a piece of old fuel line. 1 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/53/#findComment-572900 Share on other sites More sharing options...
mowerman Posted 1 hour ago Author Share Posted 1 hour ago OK, thanks for that input. I have gone through the manual a little bit and it’s not very clear on anything or at least I’m not reading it right kind of confusing so far and I don’t wanna clean up valve covers and put them back on until I’ve got this right it’s a lot easier to find compression stroke without them on Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/53/#findComment-572907 Share on other sites More sharing options...

mowerman Posted 1 hour ago Author Share Posted 1 hour ago Accessive smoking was the original problem. Norm Taunton suggested I advance the timing a bit, and that will probably cure it He told me that quite a while ago it sounded pretty legitimate to me. But velvet adjustment was also a suggested to me about 45 years ago by an older hand in LA and it worked on the 180 I had at the time I did find one valve that was too tight after second go around originally thought two cylinders off, but I was not going in the proper sequence kind of a long story now I’m just rambling but I did find one valve tight number four cylinder exhaust maybe that’s all it is i’m hoping this issue doesn’t turn into a huge trial and error caper .. bob Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/53/#findComment-572910 Share on other sites More sharing options...
