LARRY BRUDZYNSKI Posted January 24, 2008 Share Posted January 24, 2008 Perplexing question for you guy's. My service supervisor just came up and asked for a CMP shim. I thought that the new style CMP's didn't require a shim??? /forums/images/%%GRAEMLIN_URL%%/scratchhead.gif Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted January 25, 2008 Share Posted January 25, 2008 Couldn't tell ya Larry, I have never needed to shim a CMP sensor. Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted January 25, 2008 Share Posted January 25, 2008 Early on, like in '94-96, IH had different lengths of CMP's and a special ($$$) tool to check depth and adjust with the appropriate shim. It was weird- the CMP needs .030-.035" clearance and won't give a proper signal at .020", causing a hesitation. That's all old info and the '97 up CMP was made a bit shorter so no shim was needed on any engine. I know of several trucks fixed early in their life at the dealer by doing nothing more than installing a CMP shim. /forums/images/%%GRAEMLIN_URL%%/shrug.gif This applied to both T444E (7.3PSD) and DT466E engines. The colored cups are for setting the "zero" level in the dial indicator for V8 and I6 engines. /forums/images/%%GRAEMLIN_URL%%/grin.gif Quote Link to comment Share on other sites More sharing options...
LARRY BRUDZYNSKI Posted January 25, 2008 Author Share Posted January 25, 2008 I just figured it out....They are trying a band aid fix, the cam has severe wear and is hitting the cmp. I told them it was a bad idea to try to shim it, but what do I know. I'll just sit back and wait for it to come back on the hook. Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted January 25, 2008 Share Posted January 25, 2008 You're talking 6.0? Didn't Keith say they had a problem with the pins walking out of the cam? Short block time. /forums/images/%%GRAEMLIN_URL%%/shrug.gif Quote Link to comment Share on other sites More sharing options...
LARRY BRUDZYNSKI Posted January 25, 2008 Author Share Posted January 25, 2008 Nope 99 7.3 I think the shop is crazy for even trying to do this? I think the cam is walking. Quote Link to comment Share on other sites More sharing options...
