706 timing on a 282

steve in wi · Jun 1, 2012

Just checking to if someone can tell me if this is the right way or not.got the timing light out and my in book says rpms 2510 +/-40.so I set it at 2470 rpms high idle, slow the rpms to1750 and checked my timing my book says 3 degrees so I set the timing to about 4/5 degrees.so to go over set high rpms at 2470,set timing at 4/5 degrees at 1750 rpms. Is that right to et the timing at that high of idle.I used my timing light and a diesel pulse for the rpms. Thanks steve

What does it call for at 2510? That is the important one.

Question, what book tells you to use a timing light on a D-282 that uses a Roosa Master injection pump. Static timing is 1 degree btdc and you set speed advance to start advancing at approx 1000 rpm and be fully advanced three degrees, ( 1 1/2 marks) at approx 1700 rpm using the timing window. That gives you a total of 6 degrees of advance on the engine. A Roosa Master is inlet metered , constant ending of inj pump therefore the beginning of injection varies with amount of fuel injected for speed and load. You may well be aware of this but just thought I would throw it out there. I don't have a book in front of me so I might be off some on the rpms but not too far .

I'm thinking that the timing specs are going to way off using a timing light on a D282 diesel. I believe that your light is going to fire at the beginning of injection where as the Roosa Master pumps are timed at the end of injection. Using the light you would need to be in the 15° - 20° BTDC instead of 3° BTDC.
