Is that a Waukesha gas engine, Jeff?
By Hamish - 4 Years Ago
I just googled Reo 50V and there is a clip of it on fb-I see it has a Waukesha gas engine.

Thanks Jeff.

How does this Reo 50V compare with the big Sterling crane/wrecker (presumably with the same Waukesha?) for their intended work application?  Also, how would these two models compare with the big wreckers Federal 606/ White 666?  In terms of intended work application?  They were all front axle drive, heavy wrecker boom/crane.  I'm assuming different engine sizes and axle capacities, but were some more crane than boom wrecker?

Always nice to have some extra pieces from an Erector Set to build the rotisserie!

What, no more laying on your back to sandblast the underside of the frame? Can't a man have any fun?

So this crew gets to see WW II heavy 6x6 chassis construction!  Can you guys document some comparisons between the Reo frame and the Biederman?  If the axles and engines are the same, or different?  If they were intended for different types of work, wheelbses, winches, could that be part of the record?

Jeff, very interesting details-re the running gear on those big 6x6 WW2 trucks, thanks.
By Bruce Ohnstad - 3 Years Ago
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?

By Bruce Ohnstad - 3 Years Ago
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?

This a mighty old REO being reborn. It's name is Willie Make It ll, because it's headed to a show this summer, restored.

the project begins, will he make it?

The front axle's being rebuilt.
More to come

Ken's latest project is a 1945 Reo 50V, a 12 ton 6x6 wrecker built for the U.S. Navy. Only 200 were built, and we only know of three survivors. Ken's is the only one that runs and operates. The goal is to have it ready for the MVPA show in York PA in August.

This is what it looked like prior to starting on Saturday




By Monday it looked like this.

It's a 145GK Wauk Hamish.

Bruce, you ask an interesting question. Most of the information we have on these trucks is pieced together from several sources. The Reo 50V and the Sterling DDS235 Navy wreckers were essentially built to the same specifications. Both share the same Waukesha 145GK engine and the same transmission, transfer case, drive train, and Gar Wood US6 T26 wrecker boom. The cab and sheet metal, and the Sterling wood lined frame were the main differences. Reo literature refers to the 50V as a "10 Ton Naval Aircraft Salvage Truck", but the boom was rated at 10,000 lbs (same as the Federal C2) and the data plate stated the truck was a "12 ton 6x6 Wrecker Truck". There is no doubt the chassis is much heavier than the 7-1/2 ton Federal. The Reo chassis rails are heavily fish plated from the factory and the truck seems much more massive. The top of the engine valve cover is about 7 feet off the floor. A Reo factory image of the 50V next to a 7-1/2 ton Reo 29XS (same chassis at the Federal C2) shows the 50V to be substantially taller.

Both the Army Air Force Federal C2 and Navy Reo and Sterling had the same purpose, to recover damaged aircraft. The Air Force trucks were equipped with a 5th wheel and an underslung winch on the rear, while the Navy trucks were just a bare chassis behind the boom tower. The only drivetrain components shared by these trucks was the Timken T-77 transfer case. The Federal used the Hercules HXD engine.  

There was never a wrecker built on the White 666/Corbitt 50SD6 chassis although some civilian operators added them after the war.

Ken's 50V project is moving right along with the engine, transmission and rear differentials removed from the chassis and the front hubs rebuilt by the "Hubmaster" John Gott. To facilitate cleaning and painting the frame Ken has built a rotisserie to turn the chassis to whatever angle he needs it at. Here are some photos, courtesy of Warren Richardson.

why was the rotisserie moved inside? I'll bet you a beer it doesn't get scrubbed on the new concrete floor since Ken covered it up to keep it clean.
Fix the springs first?
By Jeff Lakaszcyck - 3 Years Ago
I wasn't there, but some little birds have told me there was quite a bit of work done on the Reo 50V project this past week. Since the last report the frame has been sandblasted and primered. One of the worst issues on this truck was that it had a severely broken rear spring. This is one of those times that you wish an old truck could talk, because there must be a great story about how the hell this happened. No one knows. So where do you find a replacement spring for a seventy year old Reo wrecker ? Well, you don't. Ken found an old spring shop in New Hampshire that could make two new rear springs to a engineering drawing that Warren Richardson made up. This week John Gott and Warren disassembled the new springs, painted the leaves (using KBS products, I'm told), and re-assembled them. Then Ken and the crew installed them on the chassis. One other issue with the truck was that the Timken-Wisconsin T-77 transfer case was shot. Fortunately nearly every big WW2 6x6 used this transfer case, so they are not hard to come by. The chassis from the Biederman parts truck was rolled into the shop and the transfer case was removed. Disassembly revealed it is in fine condition, some new seals and it will be good to go.

Thanks for the update Jeff. It's coming along nicely.

"One of the worst issues on this truck was that it had a severely broken rear spring. This is one of those times that you wish an old truck could talk, because there must be a great story about how the hell this happened."

I believe this happened quietly over many years of sitting dormant. Usually salt which has an affinity for water will form a layer of rust between the spring leaves. As more water is attracted to the salt the rust will "grow" in  thickness and eventually bend the spring beyond it's yield point breaking  the spring.

A common thing here in the north.
