If you keep on just poking along like you are you might be surprised at just what can be achieved with out spending bugger all Nice and steady, you may get away with no sleeves or pistons or maybe you will need just one or two Paul

We nerd KS to provide some info on this, dunno how big that back is at but huge is a fare guess Looks like a Alsakan Freight lines truck, or that style of truck Paul

They would probably still be peeling my fingers off the steering wheel lol Paul

If someone is putting a lot of force on a crank to move a seized engine then pushing as sleeve out is well with in a possibility Then as Joey suggested these are a press fit or freeze and get back This is all gunna be a challenge with a pistion still stuck in a sleeve Anyway thats how I would deal with it Paul

Very good, please feel free to share any photos or memories Paul

Not a lot to add but interesting

I reckon your right, this isnt as easy to notice if you dont know we're to look The bolts towards the center of the camel back I doubt anyone can easily see from walking around doing a pre trip inspection So depending on how the conversation went with mechanic I can sort of understand how this could all unfold quite easily Gotta remember the mechanic can only goes on what is described to him and the driver can only describe as best as they can I dunno we need to try to not be to critical after the event Bloody lucky everthing survived the ass puckering adventure at 65 MPH I reckon, I know I would of had white knuckles pulling the truck up Anyway I'm sure all involved are well on the way to getting things sorted now C4Ed I'm judge you the truck or anything else just chucking some thoughts about A lot of the people on here are really experienced in all facets of Macks so dont judge them to hard as they can only call it like they see it Paul

Once you yank the heads, before trying to turn the motor make sure you clamp the sleeves in properly other wise even when you get this free your gunna enter the world of clusterfuckerie with a masters degree If you accidentally move the sleeves you will turn from adventure to a in frame rebuild quicker than you can say "bugger me" Anyway, it's all good fun and adventure so far Paul

Well this is good news, now that's gumna sound strange But let me explain, you stopped forcing it before you went to far and broke something Mouse piss etc should be of concern, or at least it would be to me, must be some valves open either fully or partly How did these mice find their way into your motor ? Paul

Bananas in the gear box, mate we have all the answers at "Dodgy bros auto repair"

This is the gear that is reported as the go to deglazer used car sales man instant rebuld kit in jar bombdiggitdoo kit This will save you bucket loads on those over charging money hungry pescky mechanics 🤣🤣 Paul

That would of added some excitement to the day Gotta ask the question, did you get under and have a look when you first noticed it tracking out wide ? Thinking it might of had a broken or missing bolt that could of easily been noticed And Mack Camel backs do track a fair bit Paul

I would be guessing you blokes are right about the rolled O ring That been said the motor was probably rebuilt by a normal bloke like most of us and didn't even realise I doubt commercial truck owner would of rebuilt this for commercial use So we shouldn't be to hard on who ever rebuilt it, I'm thinking it was done with the best of intentions I wonder if the motor sitting for so long got rust in a groove of the twisted O ring and the rust cut thru the O ring with heating and cooling If this had been im continual use I wonder if it would of happened at all ? Paul

Silverfrost paint was common to find on head gaskets in Australia maybe 30 years ago or more but havent seen anyone use it for a real long time now I have used copper spray, only if the head is in a really difficult spot like a COE truck without a tilt cab Paul

I was going to go to a truckshow, yes it shocks me as well, so put the truck on the trailer as it is easier for me to wash underneath it Well I washed away and it has rained and rained and rained some more This is all heavy self mulching clay here and adter 1/4 inch of rain you.can move so the truck sits I have done (hopefully) sone improvements to the sir start as it is fed direct off the wet tank and all the dirtest air goes straight from the wet tank thru the valves into the airstart air tank This causes anyoying leaks as crap gets under valves Anyway dont wanna corrupt Vlads thread here to much Oh and another 20 mm (3/4 inch) over night, thats helped no end Note I did shift Mrs Mack since the last photo The bull bar is off as I was gunna polish it up shinier than my head bald head on a hot day, and do some repairs to it as well Sorry Vlad Paul

Welcome and thankyou for your information Please feel free to share any knowledge on Macks from your part of the world Paul

refractive lense never heard of such things, as long as they work I guess and sounds like they do Paul

I would agree, you can see there's issues, dont want to make it worse Gaskets and the like are cheap Paul

Miss Molly the border collie is waiting for me to get my act together Paul

There's some good reasons to not force the engine to hard mentioned here My thoughts are fairly similar, if the truck is home and you are capable of mechanical work to me it's a no brainer, pull the heads and have a look Because without doing that you have no idea what's stuck, everyone here is assuming pistons, it really could be anything and the chance of causing a major issue is pretty high and could be easily prevented by pulling the heads and having a good look Not only that it gives you the chance to clean 50 years or more of crap off everything and not have it pumped thru the motor Anyway thats just thoughts Paul

No definitely not Drop the tail shaft, put in gear and use a porta on the yoke of the tail shaft to move the motor Pry bar is the go, lots of possom piss as Hayseed suggests Be careful with heat as you might crack the head or stuff the injector People sometimes screw a slide hammer into the top of the injector, but this normally just breaks a really stuck injector Paul

It's come up well Vlad I find most metric fittings and air lines etc work well enough with imperial, just use some thread sealant Yes projects have a habit of blowing out in the time department for me, was going to go to a truck show a few months ago and turned my Mack around and parked her on my low loader to give her a bath Well it hasnt stopped raing since so it is stuck high and dry Paul

Well done

Anyone that buys these old buckets of bolts is paying to much I have no idea about the price in the US but 5grand for a B model in Australia would be a steel Paul

Seed these are Trev Jones and the Princess took some as well so credit to both of them Paul
