1952 CJ-3A APU Portland, OR $7000

• CATEGORIES: CJ-3A • TAGS: , .

Carl and Marty spotted this APU. It appears to be missing the extra gauges, but does have the original data plates, the hood, and the correct engine. The soft top seems to be a Dualmatic, as it has the large square rear window and the two-part doors with snaps (thanks Pascal!).

1965 M-151A1 APU? Branford, CT $2000

• CATEGORIES: M-151 • TAGS: .

This includes some interesting historical info about why no M-151s were built to be APUs. The question seems to be, was this a motorpool modification or someone’s backyard customization.

https://newhaven.craigslist.org/cto/d/1965-m151a1-mutt-apu-ford/6654432656.html

1965-m151a-branford-ct2 1965-m151a-branford-ct

“Not much is known about the history of this little MUTT except that it was an original Ford built M151A1, produced in 1965.

On the back is a rather elaborate electrical generation set up, that includes replacement of the transmission with another generator unit. Power comes from what is believed to be a Continental flat head 4 cyl. The vehicle moves by an Autronic Unit transfer gear set-up that hangs off the front of the small “jeep”. A shaft coming off the front of the crank runs a chain that drives the “transfer case” that powers the front axle. Continue reading

• CATEGORIES: CJ-3A • TAGS: .

UPDATE: Price dropped to $2300.

(03/02/2018) Bill shared this ad. There’s no sign of the extra gauges, so I can’t tell if this was an APU jeep or if the hood was appropriated from an APU jeep.

UPDATE: **SOLD**

1952-cj3a-apu-salem-or5 1952-cj3a-apu-salem-or6 1952-cj3a-apu-salem-or7
“This is a solid 1952 Willys Jeep. It runs well and is drivable, but will need some brake work before it’s ready for the road. It has the overhead valve engine. The hood scoop is because it was updated by the military to the overhead valve engine from a flathead, and more room was needed for the carburetor.

I’m no expert, but here is a brief description of the APU conversion. They were converted by two companies for the military, O.E. Szekely and the Valentine Welder and Manufacturing Company. The APU stands for auxiliary power unit, and they were also called jet starter jeeps. The military converted these Jeeps for use in the Navy and Air Force. They were used among other things to start jet aircraft. There were a few variations, they made both 3 and 4 wheeled versions.

The right seat and factory toolbox underneath it were removed, and a pto was run up thru the floor towards the right seat well, to power the generator. I will attach a picture showing one, and here is a link to get you started:

1953 Custom APU Los Angeles, CA $3600

UPDATE: this is still for sale Vince wrote a post about this at the DailyTurismo.

Rudy’s selling this rare purpose-built APU on a jeep chassis.

“Very Rare 1953 limited production 4X4 specially built for the U.S Military by O.E Szekely and Associates. This is an all aluminum body, tub, fenders, and hood so theres no cost for rust rot work and repair . Dual Aluminum gas tanks so theres no need to worry about rusted out tanks. The Chassis is Jeep. The engine is a Lincoln (ford) 317 V8. This is not Frankensteined, this is the original way it was built for the Navy to jump start, run system checks, and tow jets. Do not have the generator equipment. does not run and is for restoration or customize purposes. As is where is. Unique, rare and easily bad ass potential. Add seats, swap motor, take the paint off and pollish the aluminum body, run through the chassis. pink on hand. first $3600 obo takes it.”

1945 GPW Early APU

• CATEGORIES: Features, GPW (Ford MB), Industrial-Welder-Generator • TAGS: .

Nick spotted this very interesting early APU conversion of a GPW by O.E. Szekely that is for sale at D&L Bensinger.

Nick, who’s become very knowledgeable on the APU jeep, noted that the GPW was “converted to an APU in 1947. To date, this is the only Line Maintenance GPW survivor. This specific model is “B” and the generator outputs 28.5 DC volts for starting jet aircraft. These retrofitted Jeeps served as prototype models to the later 2A/3A’s. Nearly all the equipment is present. The only part I can see is missing from the photos is the wire reel. Notice how the governor system appears to be under the carburetor, and the hood is modified above it.”

Here’s the ad info: “This is a late war GPW. Vehicle hasn’t been run for over 10 years. Body is rusted. Has one rear axle shaft broken. This jeep came from Omsted AFB in Harrisburg, PA which closed in 1969. It was modified in Philadelphia with Flight Line Maintenance Generator Set. In 30 years of jeep collecting, I’ve never seen another jeep with this equipment. GPW still shows yellow paint inside and a radio mike on the shop-made aluminum half cab. The cable reel to aircraft is missing as are some other parts of the kit. This is a great project for someone who wants an air field jeep.”

Searching For APUs

• CATEGORIES: Features • TAGS: .

Tom Sterndale has been building a database of existing APUs, a challenging task given how little they’ve been documented. As part of his effort, he hoped to identify these jeeps which were once listed on eBay.

Tom writes, “Help me prove that ebay is not a black hole out there some were sucking up all the Szekely APU’S.

  1. The four pictures of the four wheeled APU is a NC/5 Szekely used by the Navy up until the 70’s. Was on Ebay in 2010 would like to know were it is now.
  2. The pictures of the Tricycle APU’S are NC/1 Szekely’s they were on ebay in 2003 or 2006 I would also like to find   them or others like them.
  3. Both the  NC/5 and the NC/1 used Willys Jeep as a base.I have found some APU’S like the red and blue ones they all seam to be NA/3 Szekely built for the Air Force. I

I am trying to keep a data base of all units that I can find any body with a Szekely of any type I would like to be put in contact with them.”

Where do I even begin? This is a very rare and authentic piece of military history; it may be your only chance to own a vehicle like this. If you search “APU Jeep” this very Jeep is all over the internet. It is a 1951 Willys Jeep CJ3A, but was specially contracted by the US Navy to be used as a mobile power unit. This is known as an APU (auxiliary power unit). It’s sole purpose was to start early jet-aircraft as they did not have on-board starters. It utilized a PTO-driven generator off the transfercase and fed power through cables to the jet. The equipment was so heavy duty, the Jeeps were equipped with larger engines that weren’t even available to the public yet. Two different manufacturers built these Jeeps: A company named O.E. Szekely which a handful of Jeeps are left, but none have any of the original jet equipment. They are only known by their data plates. The other company was Valentine Welder & Co.

O.E. Szekely-built Ford-Powered 4WD APU *FREE*

• CATEGORIES: Features, Other 4x4s • TAGS: .

UPDATE: Rudy is willing to give this away for FREE if someone can pick it up by this Saturday the 16th. He’s located in Hollywood, California.

(12/18/2016) Rudy just purchased this rare and unusual O.C. Szekely-built Ford powered four wheel drive APU. It’s got a an Szekely badge and an O.E. Szekely stamped transmission. I don’t recognize the transfercase, which falls to the driver’s side rather than passenger side.

Thanks to some careful research, Rudy discovered that this vehicle was one of eight deliver to the military on August 25th, 1953. Specifically, “”The vehicle is a specially built two passenger 4X4 truck powered by a FORD eight cylinder engine. . . . A generator mounting chassis, located between the seats, supports the two generators and generator drives” and the “transmission that incorporates the transfer case is designed to transfer engine power to the generator drive”. O. E. Szekely dropped off eight of these vehicles to a shipping service on August 25th, 1953.

Nick’s APU Has a Generator

Nick & his Valentine APU

Nick’s got an update on his APU:

“Last week the stars aligned for the Valentine APU. For months, Tom and Arno have dug through vintage photographs and literature to see what the correct generator was for the NA-4 APU. We finally had it figured out: a Jack and Heintz G32. What would you know, a single G32 was actually for sale on eBay! It was unreal.

The owner purchased the generator from California where it was completely rebuilt. His original plan was to build an electric car with it, but the project was never started. Having original paint was the cherry on top!

This weekend I pulled the PTO system off my Jeep and unseized the shifter. Everything else worked great. The generator slid into the shaft like a glove, and the bolt pattern was perfect. I still can’t believe it.”

More on APUs

• CATEGORIES: Features • TAGS: .

Nick and tom have been continuing to research the APUs. They have some additional photos and documents to share, along with a story from Dennis Flynn, a former driver of an APU. Below is his tale, along with a photo of him now and of his former self in an APU.

Dennis-from-apu-combined

Dennis Flynn photographed in an APU jeep and one of him now.

Dennis wrote,

I was 18 I made 3rd class Petty Officer and was put in charge of a 12 man start/tow crew working the flight deck on the USS Hancock CVA-19, Essex class attack carrier built in 1944 scrapped in 1976.

Early version of the jeeps used in the 40’s and early 50’s, the yellow ones were mid 50’s through mid 60’s. and cut down quite a bit. The rear axle was moved to the front and steering was done using two small wheels mounted in the center rear, the hood bulge was done to clear the carburetor since the body was lowered. ( it was like driving a tricycle backwards ) and they were pretty squirrelly to drive. A governor was placed on them to keep the top end at about 14mph.

My friend of mine and myself had one torn down for a valve job and had the ships machine shop mill the head, port the intake and exhaust and we made up a split exhaust manifold and removed the governor. While at sea and when we were not flying we tried out our work. Jim took off at the front of the ship (The flight deck was 888 feet long) By the time he got to the Island he was going 65mph. Then trying to stop (this had brakes on the front axle only and they were not all that great to begin with). He was doing pretty good with getting it stopped when he started running over the 1” arresting cables on the rear causing the Jeep to bounce and really get sideways. Jim did manage to stop it about 8 feet from going over the aft end of the deck. We were going about 20 knots at the time and the flight deck to the water is 68 feet down. We both got a super royal ass chewing from the ships executive Officer but neither of us got busted. (I didn’t lose my Petty Officer stripes that I had just made, but I was also the Ships Captain’s driver so that might have saved me)

I made up a “Bragging Card” for us stating that we set a world’s record for a gas driven vehicle on a flight deck while at sea. Jim is still alive and is one week older than I am and I turned 74 last October. When you are young you think you are invincible, It was a great memory and thankfully no one was killed.”

Speed Record Card

Dennis’ “Bragging Card” for setting a speed record in an APU.

Tom unearthed this government quote for 75 Valentine APUs, one of which would have been Nick’s. Given this info, Nick’s Valentine modified APU (#19) might be the only one left in existence.

Update on Nick’s Valentine APU

• CATEGORIES: Features • TAGS: .

UPDATE: According to the Willys Spring Reunion Facebook page, this might make an appearance at the Willys Spring Reunion in May!

nick-valentine-apu

Earlier this month Nick put together a video and some more pics that showed him picking up his barn find: the 1951 CJ-3A APU jeep modified by the Valentine Welder and Manufacturing Company. It’s a neat looking rig.

Here’s what Nick wrote: Hidden in a barn since 1962. As of Feb 5th, 2016 this is the only known Jeep of its kind. Valentine Welder purchased frames from Willys Overland, and converted them into what’s called an APU (auxiliary power unit). These were fitted with PTO-driven generators that started early jet aircraft. O.E. Szekely also made APU’s, but this is the only known Valentine and also the only original Navy paint of both companies. After a bunch of research I believe this was used on the USS Wasp (CV-18). I have the original government release paper and maintenance manual. It is truly a museum piece.

Here’s the video:
