Diesel M1

[Joe_D]

Here are pictures of the Fort Campbell M1 in front of Range Control.






There was no SN or RN anywhere when I looked. Right rear was thick with paint. I have more pictures for those interested.

Isn't that everybody here Please, Please can we have more?

It does appear to be a Full Scale Engineering Development (FSED) XM1 Abrams pilot vehicle, like this one at Fort Hood - although interesting in that it doesnt have the slab on the lower rear part of the turret like other XM1s (or upper rear like on normal M1s).

Here are a few circled interest points. I'll bet one of the prototypes....






I must have cruised by that tank a hundred times, and never took any photos of it. Not really sure why.

The CWS still has the funky sideways ammo tray too.

Somewhere in the bowels of the detroit arsenal is an all wood mockup of the once upon a time proposed diesel repower for the M1 I wish I could take a camera in there and get some shots of it, but it would not be the only thing being shot.....

So, the Ft Campbell tank IS a PV. Thanks for the pics, Joe!

Of course, ALL M1s are "diesel M1s." But I know what you mean - reciprocating piston diesel, like a 1790.

Two of the XM1 PVs were fitted with 1790 engines, to test against the turbine. I *think* these were PV4 and PV5, but I'm not sure. One of them used to be at TACOM, at the GDLS boneyard inside the test track, then in a parking lot just inside the Mound Road gate, but it's gone now. This one was the hull of PV4 (without the engine), with one of the Chrysler prototype turrets on it. Some pics below - note the exhaust tubes for the air intake blower motors, a la M60-style.

This one at Campbell sure looks the same (1790 engine). So maybe it is PV5.

Here are some other shots,
Based on what Geoff says I'd say this is PV-5. But I will let this esteemed panel decide that.

I have more so if there are any particular features some one wants to see ask. I also go to Fort Campbell from time to time so If I don't have it I can get it. I guess when range control wanted a tank to display TACOM gave them this one from Detroit. I doubt the folks at Campbell know the rarity of this old girl. I bet to them it looks like just another M1.

The curious thing about this diesel saga is that whenever anyone mentions it I think of the Abrams fitted with the europack diesel engine that was demonstrated to the Greek Army - whatever happened to that vehicle?

[Neil_Baumgardner]

Probably still in GD's storage.

These comparison shots of what are probably PV4 and PV5 really show the hand-made nature of the 11 FSED XM1s - crude metal cutting and all.

PS - When I log in I can see the pics I posted of PV4, but not otherwise - can you all see them? (3 pics of the air cleaner boxes)

Very interesting photos, it has a JE0001 Chrysler prototype turret on PV4 chassis, I suppose? Maybe front hull photos are available?

[Andrei]

Could this be AVCR-1360 planned initially?

As far as I know, they never put a 1790 into an XM1. Only the AVCR-1360. A 1790 won't fit inside an M1 without removing the rear torsion bar and reducing the size/placement of the fueltanks. At least, that's my understanding of it based on some drawings I have seen.

Andrei, Walter,

I think I have a picture or two of inside of the engine bay of this tank that I took, if not, next time I'm at Fort Campbell I can probably get pictures of that area (if it hasn't been "Secured"). Currently I am not at home but will post them when if I find them.

[Andrei]

Thanks in advance.




Maybe there are more pictures of GM XM1, any info if it will be restored?
