Just a note for you guys one of the trucks that had the block plate started using coolant again we ended up plugging off the coolant to the cooler as well .So point being here the heating and cooling cycles of exhaust gas is only part of the equation when dealing with egr cooler leakage if you want a complete reprieve from any leaks you need to plug off the coolant passages as well.

Mp Engine Question For Mack Techs.
fjh replied to cxn613's topic in Modern Mack Truck General Discussion
Since the swede's took over the whole customer service thing has gone out the window!I have to pause and think Do they treat there Volvo customers the same way??? Or is it just the Mack side of the company? They wanted all of you Mack guys as customers but don't want to build mack trucks the way they need to be built ( MACK Tough) These Guys are actually worse than dealing with Cummins! You can also take note that that dealer that took the bull by the horns and repaired the problem Will likely not be payed for his efforts by the warranty people as they didn't follow proper proceed-er. -
I think you'll be fine with the drift idea they have J tools for everything It don't mean we use em all!Theres a special tool for setting dynatard engine brakes I used it once and never again! Most things arent magic on these things as much as they would like to baffle you with BS !The new riggs are a diffrent story thou you can't really do anything with out a puter!

What Glen speaks of is important here ! Check closely for cracks around the 9 to 12 oclock area (facing forward) on the mating surface of the diff housing! Clean it up good then run a torch over the surface and look for oil bleeding up from cracks.

The sleeve bottoms in the head!In stall it with a little red locktight! Slather the injector with LOTS of neversease on install! And make sure the copper washer came up with old injecto, If not ya need to get it outa there!

YOUR THERE Already!

Simply use a 1 1/8 boxed end wrench and a screw driver OR your thumb to push and turn till snug on a 24 thou feeler and retighten and recheck after tight!

Thanx mike that helps loads I will likly be puting the pump back on this week That cold set is just the ticket I can set the valves after the pump is on!I have spoted the engine on 25 and marked the housing in hopes of keeping it in the same spot!The pump is a standyne / rosamaster pump You can tweak the pump on the fly with these I beleive But hope to have preserved the original set!I'll run it thru a valve set before I start it as I beleive part of its problem is there is no valve lash! Hopfully there are no burnt valves!

Gee I wonder where that bolt came from on the tire? :pat:
-
Rob it may have a plate type cooler Not quite as simple as an oring job but almost! Would be guessing at the cooler as the failed part thou!

You da man http://www.tractordata.com/farm-tractors/000/1/7/176-allis-chalmers-d21-engine.html Now all I need it the injection timing and that aint no big deal I can wing that if I have too!If I couldn't find nothing I was going to set the valves @ 10 just cause I'd rather have something rather than nothing! Pump Should be coming back Tuesday! Cool Thanx Bro!

Thanx John Quite possible The engine is not in a truck or tractor, its in a Genset, I'm not sure of its HP but your description looks close ,6 Cyl turbocharged ,I got chucked in the middle of the job cause the younger ones only now the computerized things,Anyway while removing the valve cover to verify just where the engine was in its cycle I noticed that the valves are very tight And would like to verify the proper set on these before I reinstall the lid as the parts are extremely hard to buy for this thing we had to buy a whole engine rebuild kit to get a valve cover gasket for it.

As my topic suggests I'm looking for valve set specs for this engine ! I am currently working on this engine and have determined it needs a valve set as it has no valve lash to speak of at the moment. I have the fuel pump off as well at the moment being, rebuilt It would be nice to get the timing number on this unit as well, if there is anyone here on the site with some specs on this I really would like to hear from ya When I removed the pump I set the engine on 25 deg btc and the drive key was at 12 oclock when the drive gear was removed! Thanx! Fred

Amen! 31 psi out of a truck that old is hoggwash!We had (stock units) of that era cranking 40 psi! these wore all mack drivline and were allowed the XT data file at the time! Likly nowhere to be found now!
-
If Your engine is an EGR engine By all means replace the lines! Its actually the law in Mack land! You can sumtimes get away with it But Its not worth the chance .
-
OK Men we got the 1850 in there and havent heard from the Rodent Man So I'm Hopen we put this issue to bed! This Was yet another lesson in reman clutches for our parts guys which they likley will NOT learn from!
-
I don't remember the specs for that but I would guess somwhere in the hood of 50 foot pounds they are 7/16 bolts! DON'T REUSE that damper REPLACE IT if that came loose out of the blue somthing is wrong and its likly the damper its self!

DOT Requirment here in canada is 60-90 psi in 3 minutes!As far as I am concerned even that is to slow.

Hey 68 He, mentioned he had no black smoke I was thinkin a fuel input issue! Do you have any intermitant or consistant Codes??
-
what trans do you have? If it Is a Mack trans check to see the torque limit is un pluged that will cut your boost in half instantly.
-
WHAT HE SAID!
-
The most common failure on these is the fuel pump switch or the above mentioned tab on older models! On The switch style one the cable is ussually what causes the problemYou may have to add and extra spring to the lever.

I agree , Hes givin ya straight goods,If Ya got the money DO as as hes says duratlite If not, don't waste the money that is not a a bad leak It really has to be a gusher before it will affect performance!
