Joey Mack Posted May 13 Share Posted May 13 dont replace the EUP's..!!!! check the engine wire harnes first.. the wires at the EUP's are bent around the EUP, and the insulation cracks open.. Please take the time to remove the EUP wires and inspect them for cracks.. EUP's are tough... 1 Quote Link to comment Share on other sites More sharing options...

Artful dodger Posted May 14 Share Posted May 14 I looked at eup wires till my head spun off fellas a couple questionable but not on the cylinders that where throwin faults is there a way to test these to see if they are working right. Also found out compressor that was on truck was not the correct compressor and found out there is a check valve in the fitting that goes into the block on the fuel return line whoda thought right so finding a 45 degree fitting with a check valve in it that fits is yet another egg hunt lol Quote Link to comment Share on other sites More sharing options...
JoeH Posted May 14 Share Posted May 14 I believe it's a Pressure Regulator on the fuel return. Maintains fuel supply pressure in the block gallery to keep fuel pressure adequately supplied to the EUPs. Probably a few different air compressor brands that are interchangeable. If it's operating well and the truck's air system maintains air pressure safely then run it. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 14 Share Posted May 14 The 45 degree fitting is a regulator, 80 PSI.. Quote Link to comment Share on other sites More sharing options...

Yup and if you insist on changing pumps use new bolts to install! also you need to install Cal codes into the computers brain if he doesn't have the VMAC 3 software on his lap top you my need to go to a shop that does so write down the numbers off the pumps and there location so it can be done! 1 Quote Link to comment Share on other sites More sharing options...

I know what its like to have someone breathing down your neck! Make sure he replaces the bolts and make sure to get the cal numbers off the new pumps and their locations if he doesn't have the Mack soft ware! 1 Quote Link to comment Share on other sites More sharing options...
Artful dodger Posted May 15 Share Posted May 15 Ya I do too and I honestly haven’t even been around him except one other time since he has had the truck and try to keep my distance. Great mechanic but has never laid eyes on this particular Mack engine it wasn’t multiple ? I asked it was 1 but it’s ok and yes the cal numbers and locations are being put in he has software for that. Cross fingers we are done today Quote Link to comment Share on other sites More sharing options...

Popular Post Artful dodger Posted May 17 Popular Post Share Posted May 17 Hello fellas Fjh, joeymack, Hienz . i appreciate what you all did for for me stickin with me on this last ordeal I know sometimes im not easy to deal with being full of questions all the time and pretty ignorant to Mack’s in general . I did however learn a great deal about what I have what can and can’t be done with it what shit is actually called instead of my outstanding descriptions of parts.. we finished up used front1/3 of manifold $200 compressor with gear $1600 6 new eups $2300 and studs and gaskets a whopping $1300.00 new air filter new airline out of compressor new fuel return line . I know that I probably could have got some stuff cheaper from Hienz but I didn’t want to aggravate an already uneasy situation so I just stepped back i think it was a good decision..guy workin on it did a very good job so we have hauled a bit with it and more lag or delay in the throttle response no more smoke air is clean and dry turbo spooling up well climbed a hill this morning that 2 weeks ago with 18 tons in the bed I had to climb in 3 rd gear walked up it this morning in 6 th so power is better 1 3 Quote Link to comment Share on other sites More sharing options...

The Heinz Posted May 20 Share Posted May 20 It's no skin off my back, just glad you're able to get the truck going again. I was gung ho about it until I realized I wouldn't be able to sell easily to someone I know only through a forum. I'd say it may be best to have your shop look into setting up an account with us or their local dealer, especially if they see a lot of Mack's newer and old. I haven't been in the best spot to try and help out on this forum, all last week I was the only shop parts guy here and was wide open all week.

Popular Post Artful dodger Posted May 21 Popular Post Share Posted May 21 Bud you are in the ideal spot to help out you did nothing but help. Part numbers availability I don’t forget folks that go out of their way for me. And going forward am going to get an account set up with folks that take their time to help others who are struggling. If there is one thing I’ve learned in all this and what my family is going thru with my dad is it’s still ok to believe in people and invest in helping, that there are believe it or not good people still out there.. a little restoration in humanity man don’t stop helping folks on this forum your very knowledgeable and selling parts is only part of it the other part is knowing you had a part in picking someone up off the floor that didn’t have very many hands to choose from … Thanks buddy and we will get there with the account and the parts I tell my kids everyday it seems that if your good to folks they will be good in return and if they arnt then at least your conscience is clear and you can rest easy.. 2 2 Quote Link to comment Share on other sites More sharing options...
