Yep, hit the nail on the head there.

Bit cooler here this morning Paul, nice drop of rain to settle the dust as well. No good about your mum mate, that chemo can really knock them around. Looks like the Midwest is in for a few ordinary days over there. Hope anyone around there is alright. https://abcnews.go.com/amp/US/1-dead-severe-storms-sweep-midwest/story?id=119827427&cid=referral_taboola_feed

Yeah that was an Aussie built version, the mob that brings in the Reo's also do the Kalmar yard jockeys

Dunno about Diamond T, but there was a company that brought back Diamond Reo, at least over here in Aus. Based on a CNHTC Sinotruck. https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://powertorque.com.au/return-of-the-reo/&ved=2ahUKEwi81cjQrfWLAxU2zzgGHTcmBDwQFnoECDcQAQ&sqi=2&usg=AOvVaw2l6JhX7rYFnwmMhuflQDDC

Yeah I reckon that's what fjh was referring to. I'm thinking he probably has the updated design though.

Shuttle valve only allows activation of range cylinder when stick goes to neutral. The splitter gets an air feed straight from the reg, and a signal feed from the shifter. Splitter will shift as long as there is no load on gearing. Breakdown of splitter cylinder

Most roadrangers run a filter regulator, sort of like your shop air compressor filter reg. Mack usually run an additional spin on chassis mounted air filter.

He could leave the EGR crap on there, it wouldn't be functioning if he could use the AI engine loom and ECM. Providing they use the same sensors and EUPs I couldn't see it being an issue. Cam timing may come into play? Don't the AI have the restrictive exhaust manifold, and the extra bump on the exhaust cam? To facilitate the IEGR.

So the "new" motor is definitely an AC? Have never seen one, we weren't blessed with them over here in Aus. Anyway, regardless of what it is, someone has put considerable effort into making that engine look "new". Couldn't replace a hose, but painted all the bolt heads, fan mount faces and a few nuts silver🤦🏻‍♂️ Without pulling it down, it's nothing more than an expensive boat anchor. Sorta like putting lipstick on a pig. Just sayin.

There'll be slight differences in some of them, inlet outlet position and connection,manifold mount angle, etc. Some are just supersessions of previous numbers and some will reman numbers. These guys are in PA, might be worth a call. https://momentumworx.com/mack/?srsltid=AfmBOopssZviGnxvGTkEhr2LIJZFpAGTZp41VDAq7NheTnzhhL1opr-z

Good work mate, all good things take time. Hopefully you got to enjoy the down time.. So now the big question, is the new motor an ASET AC? And if so, can it be sold to find an AI?

Should have an 18spd Eaton in it. Funny how all the fluid filters get changed, but that little air filter gets forgotten about. Had a 15yr old truck come through that still had the paint on it from factory 🤦🏻‍♂️. Sounds like it's lost pressure and kicked itself out of high split? Shuttle valve would play havoc with the range shift not the splitter, I think? Joey, you'd be all over these trucks, Etech CCRS roadranger, mostly meritor drives on hendrickson air. Only real headaches are the cab and electronics, being Renault. And that they're now 20 odd years old.

Good find there Bob. Bugger you weren't a few days earlier. At least you got onto some good tires out of it. Adam
