Craig N Posted November 18, 2022 Author Share Posted November 18, 2022 Having trouble finding someone to haul the donor truck at the moment, so might be looking to rebuild the 673 or put a 237/285 in. All options open still Quote Link to comment Share on other sites More sharing options...

Popular Post doubleclutchinweasel Posted November 18, 2022 Popular Post Share Posted November 18, 2022 Okay. I haven't had anything to say on this one up until now. Just been enjoying reading it! First off, I have to point out again how similar the Aussies think to us old hillbillies! We seem to try to make the most out of what we've got to work with. Probably for the same reasons! Where I grew up, we didn't have the luxury of trotting down to the local store and grabbing new parts...nor the money to do that. So, we got really good at salvaging what we had and working with what we could get. Anyhow, regardless of whether you can find a newer engine to drop into that thing, I would still be tempted to pull that one all the way down, and for 2 reasons. First, it still may be salvageable. But, even if it isn't, it would be great experience to pull it apart and see how everything inside there works. And what you have left would be no less valuable than what it is now. I once bought 2 400 Pontiac engines for a project I was doing. One was running and the other was locked-up. When it was all said and done, I ended up using way more of the locked-up one than the running one. Anyway, I'll go back over here in the weeds now and just watch what happens! 1 4 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

I put a 2 filter spin on the old 673, so I knew the 237 would fit fine. 3 Quote Larry 1959 B61 Liv'n Large......................

davehummell Posted November 19, 2022 Share Posted November 19, 2022 Larry that looks like my engine right side starter and two spin on oil filters and I have the power steering pump mounted on the air compressor and I painted mine Mack gold. 1 Quote Link to comment Share on other sites More sharing options...
mowerman Posted November 19, 2022 Share Posted November 19, 2022 Didn’t you guys mention you have to move the transmission back a couple of inches I thought that’s what I heard…. Bob Quote Link to comment Share on other sites More sharing options...
Craig N Posted November 20, 2022 Author Share Posted November 20, 2022 Well, I’ve let mystery oil sit in the cylinders (still only have the front head off) for about a week now and the oil has gone by the first two but still sitting on the #3 piston that looks like it got heated up. Will get the rear head off next week with any luck and do the same on those. The cylinder wall doesn’t look too bad either. Might be able to make this one work with rings. That said, I’m going to look at a donor truck on Monday that’s local to me. Runs great supposedly. Has an air start and is an ENDT. Do the turbos make much difference in HP? It’s a 10 wheel dump truck which gets used regularly for the guys stone wash plant. Has a quad box too which I really want over the duplex. Body is rough, but that’s fine since the body I have is nice. Gotta see how it is. It’s the right price too and I have a guy who will haul it locally. 1 Quote Link to comment Share on other sites More sharing options...
BOBWhite Posted November 20, 2022 Share Posted November 20, 2022 Intercoolers make more of a difference than turbo's when it comes to power. That is if it has the tip turbine intercooler. I'm really exited to see that mack with an air starter! It'll be a showstopper for sure! 1 Quote Link to comment Share on other sites More sharing options...
mowerman Posted November 20, 2022 Share Posted November 20, 2022 I heard the turbo ads 50 hp but they do sound better. Good luck whatever you decide. … Bob 1 Quote Link to comment Share on other sites More sharing options...
Craig N Posted November 20, 2022 Author Share Posted November 20, 2022 Thanks for all the help on here!! I’ll keep updating as I make progress. Hopefully have some pics of a new to me truck tomorrow. I hope it’s what I’m looking for Quote Link to comment Share on other sites More sharing options...
Craig N Posted November 20, 2022 Author Share Posted November 20, 2022 So, the two cylinders that let the oil by, they look real good. Top of piston too. Anyone think the rings are stuck in the piston grooves to have the oil leak by like that? I’m probably gonna tear this whole motor down. May not get rebuilt, but we’ll see Quote Link to comment Share on other sites More sharing options...
mowerman Posted November 21, 2022 Share Posted November 21, 2022 Somehow, I still think you can fix it ha ha. OK no I do not think your rings are stuck to the piston. They’re stuck to the sleeves… Bob Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted November 21, 2022 Share Posted November 21, 2022 donor used at a wash plant would have more hrs then miles possibly. with it running, open oil filler check for blow by. Quote Link to comment Share on other sites More sharing options...

It'll be a showstopper for sure! a turbo adds hp by ramming more air into the cyls . an intercooler is just what it says, cools the air going into cyl. cooler the air better the hp. not to be quoted (memory fails often). rough numbers for compressed air out of turbo in 300 degree range after passing through an intercooler air is in the 200 degree range going into cyl. back then the hoses on a turbo engine were same. after intercoolers showed up so did the red (hot air) and blue(cooler air) hoses on pipe connection came around. 3 Quote Link to comment Share on other sites More sharing options...
BOBWhite Posted November 21, 2022 Share Posted November 21, 2022 Intercoolers make just as big of difference as power is how I should have worded it ; ) We used to run a 85 350 E6 mack with an intercooler right next to our 70 1693 Cat without an intercooler and man what a difference. Granted the 1693 is a glow plug engine but still you couldn't be behind that thing for a good 1/2 mile without getting choked out by the smoke. That Mack engine ran so much cleaner and the same if not more power than the old Clatterpiller. 1 1 Quote Link to comment Share on other sites More sharing options...

Really nice running ENDT 673. Air start, air assist steering. Runs and drives real nice. Duplex transmission. Dump body works well. Frame is nice. Stops really well. I might just put the nice body I have on this chassis. Not sure what I’m doing yet, but the price was right and it runs great.
