Mackpro Posted January 10, 2023 Share Posted January 10, 2023 One of my most used tools on the MP engines. Part number 9998288 from Mack/Volvo. Goes on the inlet side of the aftercooler and pressurizes the after cooler. Intake manifold and EGR piping and cooler. Cost about $75. It comes with a metric quick connector but we remove it and tap it to 1/4” pipe threads and add a gate valve and sometimes pressure regulator and hook it up to shop air. 2 Quote Link to comment Share on other sites More sharing options...

(Swedish ) That is the best thing for checking THE WHOLE system right there ! At one point in the engine cycle if you get it in the right spot in engine rotation .you can acheive almost full seal and build the intake pressure to operating pressure with shop air ! only done it once on an MP engine it does work! But used this set up on V8 and E7 all the time ! 3 Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 10, 2023 Author Share Posted January 10, 2023 The turbo gauge part number is only for MP7 and 8 and the Volvo D11 and13 . The MP10 and D16 use a different gauge. Quote Link to comment Share on other sites More sharing options...

Onyx610 Posted January 10, 2023 Share Posted January 10, 2023 What we working on today? Intake manifold? Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 10, 2023 Author Share Posted January 10, 2023 15 minutes ago, Onyx610 said: What we working on today? Intake manifold? Yes , bolts broke on the #2 cylinder position top and bottom. Usually they come out easy but I had to drill and re-tap the threads. Same truck that has the turbo not reaching full stroke. Lots of issues. Finally get it together and try a regen and it failed. No air pressure to the AHI . Found the air drier filter was the original from 2012! Air pressure regulator to AHi stuck. Hopefully the AHI can be saved . I’ve seen some YouTube videos of taking the AHI apart and cleaning it as 90% of the failures are dirty air supply.

Onyx610 Posted January 10, 2023 Share Posted January 10, 2023 Ahh the old air dryer strikes again, I have seen that too. I’m not sure on the success rate on doing that. Worth a try…nothing to lose at that point. It’s amazing the truck was still even building air with such a saturated cartridge. Quote Link to comment Share on other sites More sharing options...

Onyx610 Posted January 10, 2023 Share Posted January 10, 2023 That’s one of those tiny wabco driers isn’t it? Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 10, 2023 Author Share Posted January 10, 2023 Yes . They work pretty good if you change the filter. And the filter is super easy to replace so there no excuse not to keep it changed . Probably not the best out there but the ease of filter change makes up for it 2 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted January 10, 2023 Share Posted January 10, 2023 I guess you will be replacing the air lines and ahi after all. Expensive and alot more work because of a 50 dollar filter. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 10, 2023 Author Share Posted January 10, 2023 Oh yea. There was oil in the air line going to the AHI . Not good Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted January 10, 2023 Share Posted January 10, 2023 I bet the steel supply pipe coming off the air compressor is restricted by carbon build up.. Jojo Quote Link to comment Share on other sites More sharing options...
