I beleive the runout procedure came from early engines, like an E-6.. I believe they had eccentric pins that can be rotated to align the flywheel housing. But to the best of my knowledge, the E-7 didnt really need to be checked. yes lots of movement in the tranny input shaft, .020" runout, is probably nothing to worry about. especially because my E-7 book said so. It doesnt hurt to check it, but I dont know how you would adjust it. But if excessive runout was found, then I would try to find out WHY so I dont build the issue back into it again.. just my thoughts, combined with the book knowledge, I always welcome more opinion's.. I learn from them.. jojo

Bob White, You would be correct sir... I am surrounded by it.. here in central N.C. jojo

Seems to me, you guys get sh!t done.. I think its great that you are using an MR.. I think they are great trucks... jojo

I feel your pain, Bob... I really do... I get so upset.. It's hard to keep calm about the B.S. that all of us who work hard to survive, see, useless Pieces of Sh!t.. get everything for free, and protection under the law because they are not white... it's friggin crazy. and these continuous cries of racism, when they dont get what they want for free, drive me nut's.. Do the best you can to keep your heart rate down,,, i know its hard.. jojo

Check out Dowel pin # 183GC237.it's the later pin after 1992.. I believe it is a full round pin.. The bladed pin you have is ok, but you may feel better with the pin I posted. I'm into this, post, so keep asking questions, and If I get off track, let me know.. jojo

ok... My Mack book shows the part # for the inner bolts w/Allison tranny as: 429GC23M... That bolt is 2 inches long.. I cant imagine it is an SAE bolt.. jojo

So It seems like the housing is listing to the right.. When were the main bearings replaced? I swear I am not trying to make a mountain out of this, just asking.. engine runs clockwise, making the thrust side , the right side.. ?? the dowel that is a blade type is older but not sure if it correct, I see full round pins in E-Tech's, the bladed pins are to be installed vertically.. the bolts on your engine are METRIC.. i dont get the 7/16 x 14 size.. I'll be right back... I will get the bolt size in a bit... jojo

yes to locating dowels,, So the reading s you have may be good.. keep in mind that the crank shaft may move eliptically because of main bearing clearence, and wear.. You are allowed .020" of runout when checking with a dial indicator on the end of the crank shaft. I can not post pics anymore, so if you P.M. your cell #, I can send pics from my Book.. there is also a specific flywheel housing for Allison's and the inner mounting bolt are specific, similar looking bolts can bottom out and not tighten to around 170 lbft properly.. I hope I can help you, jojo

are these readings posted, as they were read on the engine? is .022 at 12 O'Clock? , then 3 O'Clock, is '0' then 6 O'Clock is .013, and 9 O'Clock is .028?

👍

if the over board breather isnt puffing like a freight train.. I would just do the bottom end and an oil pump. Then freshen up the cooling system.. new coolant, thermostat, fan clutch if its viscous, even the water pump.. Terry and FJH, nailed it.. I would easily choose PAI parts for this repair.. I'm building an E-Tech now, with PAI parts.. The oil pump actually came with a new pick-up tube.. jojo

Is it a coincidence that our homeland security chief is looking away, when it comes to our southern border... He is Cuban born... who are the real racist's?? not me... jojo

Abortion used as "Birth control" is atrocious!!!. Saving the mother's life is a different story.. How the hell did these WACKO'S get so much 'Street Cred'???? The internet puts info out there instantly, and the 'sheep' suck it up as 'creed' without thinking about it for a bit before saying. 'Hell yeah, I'll make a sign and protest'... Because my feelings got hurt..... You racist white man..... anyway,, getting pissed again... Like I said, i'm not well educated... but I believe I can see through a lot of the B.S. .. jojo

I had another thought... check the bell housing flange for wear that could causes the bell housing bolts to loosen, and therefore cause the tranny to move, and crack the flywheel housing.. I had an '01 RD that had loose bell housing bolts, and I would remove them and put lock tight on them, put'em back in, and next service they were loose again.. I knew it was the bell housing, but because it was a T-2070 tranny, and I handled all maintenance intervals, I just kept tightening them whenever I saw the truck, until it was time for a clutch, then I Sent it to "Overdrive rebuilders" to get the case replaced.. and a re-build.. jojo

since it is an E-Tech CCRS engine, Flywheel housing should just bolt on properly.. It certainly wont hurt to check it, especially because of the current damage to the flywheel housing.. jojo

you can make your own 'run-out' gauge using a dial indicator with a magnet base, or whatever you make, and a piece of flat stock with (2) 5/8" holes in it to bolt to the crankshaft.. jojo

God Bless you...

Amen brother... My last go around at Mack, showed me the BS... I would use the dealer portal at home while I was doing my ProPath training, to print off as many manuals as I could afford paper and toner for.. I have (4) 3 ring binders full. about 1 whole reem of paper... just sayin'.. however, i do as much as I can to stay away from 2007 and newer trucks, in my service business.. so far, i'm ok.. jojo

Youre name certainly suit's you , Mack Pro... 👍 jojo

So that's $8.57 USD/gallon... jojo

I was hoping you would post on this..

I beleive there is a campaign on this issue.. I replaced a few of them because the 'clutch' if you will, wont grab.. If I remember right, the whole frame around the steering column is replaced as a unit, cable included.. there afre a few ways to post pics, I would just e-mail the pic to myself then drag and drop it into my post.. my suggestion is to reduce the size of the file to Kb's, so that you dont use all of your data quota in a hurry... i made that mistake, and now I cant post pictures any more.. Jojo

I read the original post again. I was curious about the evap core freezing up if it is not draining good. A faulty pressure switch is highly possible. On some earlier Mack/Volvo's, I have gotten stumped by a bad compressor, because I wasnt familiar with the internal clutch type compressor. I replaced a control panel because I thought all issues pointed towards it, I was wrong. I guess I would do a pressure switch.. good chance its a simple issue, since you said the system has never been opened up.. keep in touch,, jojo

Mike, have you put a gauge on the oil gallery to see if oil pressure is good and stays good? jojo
