Yes, thank you, Jeff.  I've asked several times and I'll print that out to help keep these models specs straight.  Interesting how the capabilities increase, wouldn't it be great to see these put to their limits.

If I'm getting my numbers straight, Herc HXD is 844 cubes, 180 HP, 630 ft lbs.  Waukesha 145GK about 779 cubes, and 1940 and 1955 Motors manual that I have don't give exact numbers on the Waukesha.  But it seems the Waukesha has a little less power than the Herc.  Gearing and application are major factors, of course.

Jeff, do these trucks look relatively sound on their frames, or do you see cracks welded?  Any major cuts/additions for equipment?

Bruce

The Waukesha 145GK appears to be quit a bit more powerful than the Herc HXD due to its higher speed.
From Motors Manual 21^st addition:
Waukesha 145GK, 779in³, 240hp @  2400 rpm, 594 ft.lb @ 1000 rpm.
With lower gearing and higher engine speed more power is available to do the same job.
See specs attached

The HXD was 855 ci, with the 180 hp version turning 1800 rpm. Later models (before the end of the war) used aluminum pistons and counterweights on the crankshaft and could turn to 2100 rpm, with 200 hp. 

Maybe Ken can chime in here but I think the frame on the Reo is in good condition. The Biederman parts frame had been converted to a crane carrier and was heavily fishplated. Ken started removing the fishplating but it was leaving an ugly mess of old welds, so the other Biederman F1's frame will be used for the restoration. As far as I know this frame is in good shape. Both of my Federal frames seems to be in good condition. These trucks were built tough and could take a lot of abuse, it seems.

That's some big power there.  I went to the start of this thread and see I asked the same questions just a few months ago.  Sorry about that.  It looks like the 12 ton Reo has 20" rims and the 7 ton has 24" rims.  Am I seeing that right?

Bruce

They are both 11:00-20's.
