Attaching Hardware

Satin Black VHT SP139 

Early – Pancake Only one which was “F” marked. AC Spark Plug Co. Model A-183-40 

There were 8000 AC pancake air cleaners to be used on the first contract production and at the end of the day on March 23, 1942 7937 GPW's had been built. Both figures are from Ford Archives of GPW production / contract records. Each plant should/could have run out of the pancake air cleaner at different times. The records of when the change happened at each plant may or may not ever be found. (Tom Wolboldt- '09)

Followed By:-

With Decal Instructions March 1942 - Mid (June or July) 1942

With Spot Welded Plate Instructions Mid 1942 - Late (Oct/Nov) 1942

ENGINE

Ford record indicate that on 1May'42 motor # 26207 was the first to be painted M-4084-G Grey paint. On 24Sep'42 Ford started using M-1788-H Grey paint ( same as the 9N tractor ) on GPW engines. The records do not show what paint was used for the GPW motors before #26207. The GP used the 9N Grey ( M-1788-H ) on the motor and this may have been carried though to the first GPW's. Ford motor assembly records show paint # M-1788 Grey for 9N and Ford designed 4 cyls. before GPW # 26207 and paint number M-1788-H Grey after the 24Sep'42 date for GPW and Tractor motors.

VEP* Ford used the Willys Chassis (Frame). GPW stamped Willys frames have been found up to GPW 15064. This is possibly one of the last Willys frames used. If you have a later Ford Stamped W-O frame contact me.

Note:- GPW 14944 has a pure Early Ford stamped frame. This may have something to do with different Ford production plants.

The vehicle identification number (VIN) can be found on the left side frame rail, at the front, near the left motor mount. The number, typically, looks like *GPWxxx* but there are many variations.

Generators Used on Both Ford & Willys

From Ford documents, the Ford made generator with sealed bearings was started on June 16, '42. Prior to this date Autolite generators ( GEG-5001A and maybe GEG-5002D ) were used. NOTE - there is no data that I have seen showing the Autolite made generator GEG-5002D was ever used in a GPW but it may have been so more research needs done on this point. On the second GPW contract 20,184 non Ford made generators were used before the Ford made generators started to be used in the production of GPWs.

In Nov. '43 the Ordnance Dept. issued instructions to eliminate the use of ball bearings on the commutator end of the GPW generator.

On Nov. 29. '43 a quote was given to the Ordnance Dept for the price change affected by the above instructions.

On Feb. 23, '44 Ford states they have $15,000 worth of obsoleted generator parts on hand due to the change in generators.

From this data I would say Late Jan. or early Feb., '44 was the date Ford changed to the Autolite GEG-5101D generator from their own made generator. (Tom W.)

Sparton R2-14  Outside- Japan Black  Inside- Trumpet Black (Lacquer not Enamel ) Sounding plates are plated Attaching "Rams Horn" is also plated as is the mounting bolts which are "F" Marked  

UPDATED 27March 2010- Originally I had these as NOT "F" marked, however, it has recently come to light that as there are only two bolts of this size ( TWO (2) 1/4-28 x 5/8" bolts ) fitted to the jeep and that have been found fitted to a Reykjavik, Iceland find jeep, it would appear that at some stage these bolts were indeed "F" marked.

It should be noted that as these "F" marked bolts are so rare there's a posibility that these were phased out over the production of the Ford made jeeps.

Round head machine threaded bolts are Plated. Electrical contacts are Plated. Photos of an original, unrestored horn below.

SPARE FUEL CARRIER 

AKA Jerry Can Bracket

TB ORD-92 Mounting the 5 gallon spare fuel Carrier . Pdf File

A basic identification is as follows.
(1) Six holes on the underside (two large, four small)

(2) Underside has a stamped, recessed area left and right to accommodate the folded tabs from the sides.

(3) Reinforced fold where the straps meet the bracket. These could be missing as some were just a clip on arrangement.

(3) Part Number "42-B-22590" stamped... MAYBE! Maybe not!

The late war (Ordnance Drawing) part number was D66675. After WW2 the 7,xxx,xxx Ordnance number was used.

 If Fitted - Olive Drab Primed with Red Oxide

2 webbing Straps attached with brass rivets. See TB ORD-92 Pdf File

GPW was FM-GPW 1140330. To my knowledge, none are so marked with a part number or "F" stamped.

To be 100% certain you have a genuine WW2 spare fuel carrier you need to check some numbers, usually stamped 42-B-22590 or D66675 (Late War Drawing Number), [ Have been found on the front face, either left of right side of the front strap slot, Extra stamp on the vertical/sloped side (not as common) ], now having said that, unmarked ones are also correct, provided they follow the correct manufactured folds, tabs and indents and hole locations. Many GPWs have been found as original with non-marked brackets

42-B-22590 and A-4123 JARVIS CUTTING TOOLS INC. Part references still referred to today

If Fitted - Olive Drab with Red Oxide primer

2 webbing Straps attached with brass rivets

Willys Part Numbers are A-4130 and later WO-A 4123
