I do have a son who is also mechanically inclined that I taught auto and light truck mechanics to. Albeit per 1980"s but some stuff doesn't change. Also have a son in law who has his own truck that does alot of his own work, so I think I am good for a GOOD helper when it comes time. Today is cleaning parts day, worst part, at least for me, in any auto/truck job 1 Quote Link to comment Share on other sites More sharing options...

RS Disposal Posted May 14 Author Share Posted May 14 Seems I REALLY can't catch a break on this engine. Seems the camshaft I picked up last winter has a lrger journal on the rear than the one out of the engine. My bad, I didn't go to the dealer and get a part number to cross reference. This one showed 454GC580. Guess I make a trip to dealer and get a part number before i start looking Quote Link to comment Share on other sites More sharing options...
JoeH Posted May 14 Share Posted May 14 @heinz57 if Heinz knows how to look up the old VIN's he may be able to help you out. I don't think cam is available from Mack anymore. Also, you should be able to send your camshaft to Berry Cams, they should be able to repair your damaged lobe. http://www.berrycammn.com/ 320-395-2377 I have never used them, but it's worth a call.

The Heinz Posted May 14 Share Posted May 14 I believe yours is "new" enough Impact would have info on it. I've looked up a couple of E6's before. Outside that I don't think I have anything else to look up. I'd need the old part number your truck had or your truck's VIN. Also, I'm extremely unreliable this week. Running solo in the shop so I don't have any downtime to check this forum out before I leave for the day. Quote Link to comment Share on other sites More sharing options...

The part number my Mack guy at the dealer gave me was 454GC568B which according to PAI they had several in warehouses across the US Guess I'll see when I get the cam. Also just a FYI my VIN is MR685P1202. All the newer guys around tell me that isn't a good heavy truck VIN, hench why I just go to the dealer.

The Heinz Posted May 15 Share Posted May 15 (edited) Took a little bit to figure this out, but as long as an ENDT675 is the same as what Impact says is ENDTB675, you have the correct camshaft part number, and PAI does show stock of their version ECM-9002. This is also the oldest Mack I've searched parts for. Edited May 15 by The Heinz 1 Quote Link to comment Share on other sites More sharing options...

This is also the oldest Mack I've searched parts for. I ordered the camshaft that PAI shows for the Mack # 454GC568B UPS says I should have it tomorrow. (WOW, only ordered it yesterday afternoon) The camshaft I got that the original description saying it was for the ENDT 673, 675 & 676 was supposedly 454GC580. It has the larger diameter 7th journal. (Sealed Power CS-851) As near as I could tell other than that the camshafts are the same. Maybe that's the difference between a dynatard engine and a non dynatard engine Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 15 Share Posted May 15 Just curious?? How do you install a cam if the 7 th journal is larger? How could it start in the block? I have only done a couple of these 673-675's, so i dont have a lot knowledge. 1 Quote Link to comment Share on other sites More sharing options...

I have only done a couple of these 673-675's, so i dont have a lot knowledge. The 7th isn't larger than the rest of the journals. They are all the same size. The cam for my engine has a smaller diameter 7 th journal. The book just describes the cam as a larger diameter 7th journal Quote Link to comment Share on other sites More sharing options...

RS Disposal Posted May 17 Author Share Posted May 17 The new camshaft from PAI arrived last nite. Only ordered it tuesday afternoon. Got it in no problem. Question - Is there anything other than timing marks I should be paying attention to and also what is the accepted procedure to break in the cam? 1 Quote Link to comment Share on other sites More sharing options...

RS Disposal Posted May 17 Author Share Posted May 17 another quick question. When I opened the gasket set to get ready to put the timing cover on, I noticed lead wire (kinda like thick solder) about maybe 15 inches long. I don't remember seeing anything like this on disassembly. Am I missing something or is this possibly used somewhere else in the engine that I haven't been into on this repair. The set is a front/lower end gasket set from PAI Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 17 Share Posted May 17 thats the old lead seal, did the kit have the metal cased rubber seal? 1 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted May 17 Share Posted May 17 the thick solder is what us old folk considered a rear crankshaft seal . should be a regular type seal for rear crankshaft housing, with a wear ring . supppose to use a fancy seal/ ring installer 1 Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted May 17 Share Posted May 17 if the engine has the old style lead seal/ proper housing ; you would NOT notice it if it is still in the rear crank housing . would appear to be part of. your engine has a regular style rear seal - should have correct housing. 1 Quote Link to comment Share on other sites More sharing options...

RS Disposal Posted May 18 Author Share Posted May 18 Sorry about all the questions, but should I mess with the end play adjustment on the timing cover. have yet to find in the service manual where this is addressed. Maybe I'm just blind LOL Quote Link to comment Share on other sites More sharing options...
