I know this is an old video but there is a TSB on that large cam retaining plate. How do I know....because I just took my front cover off and it was in 3 pieces and had filed a little bit of the crank tone ring.
Just want to give a quick thanks for sharing your design! Printing the second one now, I’m doing 100% infill with petg so no worries of warping on the hot days.
Could you. Hook me up with some advice i got 870cummins. 14.9liter. 08volvo. Ive lost my jake cruise control and fuel response im get a1939code. Love your videos.
Weird cause I got a kw900 it's listed as a single cam but the cm870 uses mechanical injectors so it has a gear but still a single cam... Man I hate ISX Cummins
So, no plugs in the 4 oil galleries in the top of the block that extend directly to the main oil gallery. Next no plug on the high pressure fuel line to stop dirt and debris entry, the fuel system on the High pressure side is filtered to 3 microns about the size of bacteria. Now there is no way an ISX is going to blow a head gasket because of 0.010" protrusion. There was an issue somewhere else or you didn't measure the protrusion correctly. The issue isn't poor machining from the factory, I have measure many new blocks and found them to be accurately machined. Cummins did have the spec up to 0.014" at one time but then revised it to 0.012" min spec is 0.007". And of course there are the new liners with increased ledge area that work well. Just sayin!!
