That's what it is Dave-Thornton rear drive thanks for the info, and it seems rare.

Rare as Hen's teeth, got a good pick with that. Six lug would most likely be military or Dodge. White IIRC used five lug as did GM.

Well if you like that Indian then you will definitely like this 41 Henderson 4 cylinder Indian. 21,000 original miles on it when I worked on it and took these photos.
Ran like a fine watch it did, and I can say I've ridden a Indian 4 cylinder.

Exactly, WOW, just WOW. Heard one run at the Wheels thru time Museum in NC, an absolute gem of a place if ever on the east coast down thru Asheville HAVE to go see. Could only wish been on a Excelsior Henderson or a true high compression Indian.

Read a story once about a guy that built a small airplane with a Henderson engine. He would sneak up behind motorcyclists and they would hear him and wave him on, then he would throttle up and fly over them. This was in the late 40's.

Ran out and dragged the Freightliner home early this morning- back at the shop at 7:30. Sorry RZ the batteries went dead in my camera so no pics of the crawlers and grader.
Spent three hours stripping stuff to remove the cab, few more and it will be off and gone.

There's nothing left of that Freightliner I towed in last Sunday morning. Cab's off and gone, engine and trans are out just rear drives, steer axle and rails left.
The crank is STD, cam is in perfect shape and looking up from the bottom the liner bores are good also. I don't think this engine had more than 125,000 miles
on it. So I will install upper and lower gaskets and crank seals, injector o-rings, liner crevice and o-ring sets, main and rod bearings and call it good.

Quite the deal for $500.

No doubt. Luck prevails and you lucked out with that. I would consider a swap from Cummins to Bendix for compressor. Never cared for the slow single cylinder build up on pressure.
The damper on the crank struck a note in my old head. Is that one in the series that ballooned over time? There used to be a Tech Bulletin on micrometer checks against certain p/n's. Cannot for the life of me find that note in my files.

I too recall a spec. for the hydraulic dampers, something like clean off paint on both sides every 90º and measure and there was a spec. on how much variance. Wish I still had access to the bulletins I had in binders at the shop.
While not an official Cummins bulletin here's the best I could find with a quick Google search:

I've got the spec's on the damper in a Cummins manual. That compressor will be good enough for the little work it will have to do. Yeah a Bendix 750 would be nice but it
doesn't have one so it's going to run what it's got.

Vibration Damper {001-052} Cummins manual
Clean paint on both sides of damper in four locations 90 degrees apart
Measure and record the thickness at two points at each of the four locations
Measure the thickness at 0.125 from the outer lip
Measure the thickness at 1.0 from the outer lip
The difference between any two of the eight measurements must not exceed 0.010
But my take is that any engine with 500,000 miles on it the damper is probably toast from too many cycles of heating and cooling. I one way to tell is after running at temp
for 30 minutes the damper should be quite warm, if it's cold then it's junk. Trucks that vibrate at idle so bad you cant see out the mirrors it's normally a damper that's gone bad.
I replaced one on a N14 some years back-the driver said he could see backing up without the mirrors shaking for the first time in two years. Over looked item.

I knew of an outfit that replaced the crank in a 261B Fiat Allis scraper 3 times. Never replaced the damper until the third try. Turns out Fiat/Allis recommended replacing the damper at 4500? hours or so.

That 12509 wont be confusing enough in a Mack. You need a ten speed with 3 sticks, or an 18speed with forward and reverse on the thumb switch. Had one of those in the shop once... took me 15 minutes to figure out how to back it out.

Finished stripping out the block today, deck and counter bores all in great condition. Pistons and liners in great condition also, most time will be spent on cleaning parts
and exterior of block. Liners are standard.
