ok... too much to absorb.. stop them, and pull the truck home.. the injector cups on those engines dont crack. they are replaceable, but not by them.. never mind that right now.. drain the coolant down till its below the thermostat. remove the water pump belt, and bypass or cap off the air compressor coolant lines. then put a short length of stick hose straight up on the thermostat housing, and pour your coolant in the hose so its a couple inches from the top .so you can see it.. start the engine and watch it.. do it with the engine cold so you can have a lot of time to watch.. you can remove the thermostat for this test if you want too. if it perculates then you likely have a head gasket leak.. I dont see where you said coolant in the oil.. is that true?

really glad you came on board.. there are a lot of smart guys here.. not just Macks or even trucks,, farm tractors and other things too.. and we all get along pretty good too.. jojo

the bull gear carries the oil to the top part of the housing. the trough shaft carries it to the power divider like a screw pump. then the excess pours back into the top housing through drain holes. ( front rear),, the rea rear is the same with the bull gear, but the top housing is only splash lubed.

mack rears are filled starting at the power divider, then the side plug then the rear plug in the housing, and is only checked at the rear plug in the housing. the rear rear, doesnt have a power divider so you fill the side plug first then the rear plug in the housing.. they are splash lubed and any extra oil in the top reduction goes to the bowl via the spur shaft housing.. fix the leak you see and you should be good to go.

Yep,, for example this little $8,000.00 beauty.. I tuned it up and replaced worn parts. I have less than $300.00 in it and it works great.. They were going to scrap it..

yep... been there,,, still there,,, my co-workers dont throw anything out until they ask me if I want it.. 👍

Exactly. !!! FJH..

I have a Jabobs svc kit withe enough parts to rebuild 2 Jake heads..

UHhh,, this posting is 9 years old guy's.... 🤣

I dug through all my small Mack parts and only found 2 straight keys.. This is how they get us.. Make essential small parts obsolete. I wish I had a crystal ball 10 + years ago.. I may have bought a few of them, as well as other smalls.. Mack's price is $85.00.. I saw a PAI version for $103.00.. None in stock..

Geoff,, there was dead air on the phone. What also got me was that he was sure they didnt sell that part, and didnt even ask a co-worker or the manager to help him help me.. No concern for serving the customer... Young'ns have no clue how to ''serve'' folks..

It was hard to speak and grind my teeth at the same time... I called back and got my regular guy.. all good then, of course Mack is out of stock, and so is PAI...

Just need to get this tension off my chest. I just called my local Mack parts Dealer and asked for an offset cam key for an E-Tech.. The line went quiet, and then I hear, uhhh we don't have anything like that here. Then he says, we are a Mack dealer sir.. My blood pressure went up instantly.. I said,,,,,, AN E-TECH IS A MACK ENGINE... Anyway, I feel better now... Thanks, Jojo

The lightning bolt has to be ON..

I guess theres enough illegals here to vote for Democrats, to tip the scales. So now its time to look like a hero and close the border. They are saying that Republicans are at odds about it.. B.S. !!! We had a President who was getting it done!! What a sad state we are in.. Very sad........

Since it's a Granite.. I bet one of the rear wheel sensors has a bad wire.. keep it simple. ABS ecu are pretty tough. The ABS wires are supposed to be clipped to the s-cam housing , when they fall off they can get damaged. But I would focus on the engine code anyway.. how did you get those code names by using blink codes with the cruise control buttons?

Speaking of piston cooling nozzles, I didn't see any in the ENDT 673 that I have.. I even looked again yesterday..

Sorry Mark,, But My Great White Northern Buddy gets my vote, ehh😜

Injection pump pin and plug inspection for sure..

Yes sir.. today's price for a target is $300.00..

That's what I have. I traced a target on plexi glass 20+ years ago and made mine. Knocked the flux off a welding rod as well.. 🤣

Happy Birthday Onyx610.. Havent seen you here lately. C'mon back... Jojo

sorry about that Bud.. Is it like peeling an onion?

👎

yep, I need to take it off that stand and put it on the wooden engine pallet so I can get the flywheel housing on. I also have to put the injection pump coupler together.. The book i'm using is just 'ok'.. the assembly sequence is not very clear. I pick at this one between chores and the E-Tech that I have on a stand. as you know.. I am expecting the new lifters for it soon. Then I can do the cam bushings and get the cam set installed, run the valves, and get the 3 covers on that one.. I use heavy plastic sheets and magnets to hold the plastic up to protect the open bottom end in the shop. Thanks for the comments. I hope you get a good outcome with your tractor. Jojo
