JohnMasters Posted September 19, 2011 Author Share Posted September 19, 2011 Dude it is six or eight little bolts take them off set the engine to tdc and put it back on why are you not doing the simplest job in your todo list. I was under the impression that the main pulley bolt had to come off in order to get the timing pulley off so I was going to wait until I picked up another air hammer for my air compressor to get it done. However, If it is in fact only the 6 bolts that need to be removed I will get it done this evening. Link to comment Share on other sites More sharing options...

adamzan Posted September 19, 2011 Share Posted September 19, 2011 You only need to loosen the belts a little and take the 6 bolts out, then the pulley will turn. Link to comment Share on other sites More sharing options...
ejin4499 Posted September 20, 2011 Share Posted September 20, 2011 Just out of curiosity when you took your emissions test what were the results? Link to comment Share on other sites More sharing options...
JohnMasters Posted September 20, 2011 Author Share Posted September 20, 2011 25/25 test HC ppm - 74 CO - .48 NOX - 826 50/15 test HC - 32 CO - .20 NOX - 671 Above are the numbers from the PASSING run. I have looked around and since I did both my test and retest at the same time I must not have been given the FAILING report. When I FAILED the first test the NOX numbers were just a bit too high. As you can see, after retarding the timing, it PASSED, but not by much as the allowed NOX is 905/990 and I was at 826/671. I just pulled my report from last year and the NOX was 393 and 312 so something is different this year. Link to comment Share on other sites More sharing options...

There is also a test in the FSM about if your engine is running lean or rich you may want to run that. None of it really matters (cause you already passed) other than making your truck runs the best it can.

adamzan Posted September 20, 2011 Share Posted September 20, 2011 Wow the NOx limit here is like 590. Lucky you. Link to comment Share on other sites More sharing options...
Tungsten Posted September 21, 2011 Share Posted September 21, 2011 Most likely an unhappy cat or a plugged up EGR valve. Link to comment Share on other sites More sharing options...
