The engine is sitting in stock location, with about 3* down angle like the original was. I was going to maybe lay out mounts before installation but figure why. This was easy and was much simpler then I imagined. The 1/2" plate is about all my old Millermatic has in it. I had it in the big hole and wire at WOT. She's melted in good. Once I notched the corners to clear things, I laid out the holes for the mount bolts, then I leveled the plates 90* to the transmission and marked their height on the trans plates. Removed plates, squared them up and welded and added the gussets(corners I cut off for clearance). I was expecting a worse scenario of odd angles and offsets. Now I can start on clutch linkage. I know the arm needs 23* of rotation, so that will really help with ratio and arm lengths I need to build to make sure it gives me free play on the clutch and works the clutch brake.

I can do "ok" but not like a buddy of mine with his perfect "dimes". 😆

Thanks. For a blind guy with a band saw and an old Miller welder they turned out okay. Like I typically say...." Not always pretty but not going to break".

Today's update. I took a. 1/2 day off to get material and work on trans mounts. I think they turned out nice. Just need to dress them up and get some paint on them. Be nice to get transmission off a jack stand. Just something scratched off the long list........

Thanks anyway. I'll use Geoffs chart and come up with something. Like I mentioned, I went through this with the 237 downpipe but I used a firetruck VIN. I have another VIN to ask at dealership and see if they have something different or bring me the same clamp.

I need to investigate what the exhaust pipe flange look like. I received the clamp but it has more than a 1/2" wide groove which means the downpipe has to be super thick to make this clamp work. For reference the clamp that holds the hot/cold side together is about half as wide as this clamp. This was my concern with these v clamps. Seems there are so many variations.

It happened! It's in there. Let the fun begin.....all over again.....ugh. It went well. 1.5 hrs from friend backing into driveway until he pulled back out. Took a little finesse, wasn't perfectly engineered, but it got set in place. I can't post pictures of friends truck because it is a Cat service truck and it will get him in trouble with corporate. We just back from lunch and it just started pouring rain.

Well, the magic moment may come Saturday? It may be getting installed. My friend has been busy and I told him if we can't get together by Sunday that I was going to order a telehandler for Monday delivery. I need to get this moving, time is wasting away and it has been two weeks already waiting for him to break loose from his schedule. He told me he was busy, but could do this for me. The $1000 rental for a day is just a drop in the bucket at this point. $500 for the machine, the rest is delivery and fees. I told him I m not mad at him, I just can't continue to wait for "the day".

I got the lid off my pump and find this.. Little different from my old 237 pump rack. My wandering mind wants to tinker but I'm holding strong.....☹️. "I just want a little more..."😉

Bingo! eBay has 4.5" clamp with that old part number. Should have it here in a couple days. Thanks again!

Thanks. I asked another Mack guy and he said my 237 clamp should fit. But, mine was from a fire engine(I think) and has a cast iron downpipe that slips into the turbo. I don't think it is the same as a typical truck outlet like on the 300. It has a band clamp down below picture.

I don't have a VIN to work with, that's my problem. When I installed the 237 someone here gave me a VIN and that helped with working on it. I need a VIN from a 300+ truck. I have a VIN when I ordered the steering box but not sure that was a 300+ truck. Or how generic is the exhaust clamp between motors? It is smaller then the 237 clamp but it had a cast downpipe that isn't on this engine.

Don't think I will be there. Hell, can't seem to get the engine put back in...🙄.

I've seen both Marmon and Marman listed. More then one person has a spelling for it. I found a 4.5" clamp but from the runaround I went through on the 237 exhaust clamp 10 yrs ago, there are different widths of taper?? Not universal one size fits all. Or is it?? I went through this with Tip turbine clamp. Found manufacturer but they don't make clamps anymore. The clamp on the intake side of turbo has R.G. Ray on it. Lots of variations.

Ok, I need some assistance getting the proper part number for the exhaust clamp on my 300. It is 4 7/16" diameter flange. Mack turbo 631GC5134P4X. Dealership are pretty worthless so I haven't even tried there. I googled V band clamps but couldn't come up with a chart of sizes. Of course the input side is a different size so I can't go off of that.
