The difference between the base of  The Stamped and the Embossed Air Cleaners.

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

With Stamped body Instructions  Late 1942 to end of production

WILLYS - NOS Stamped Body Air Cleaner Photos below.

When restoring either a Ford or Willys Air Cleaner use GM Satin Black VHT SP139 These paints are specially formulated with a unique blend of urethane resins to withstand corrosion, rust, salt spray & degreasers, also, this is the closest paint available to the original so far as colour and finish.

 MB Air Horn, Notice the difference between the MB and the GPW, the groove is shorter and has some welding

Clamps changed during production The A-281 was finished in Black, the later  A-1515 was plated.

AIR FILTER CROSS OVER TUBE SUPPORT

Black or Olive Drab - See Above

Block "F" Marked on GPWs  Ford part #'s show 3 x over tubes, but the 1st has no suffix, (taller tube) the 2nd has an A suffix (short used with Oakes air filter) and the 3rd has a B (with oil filler tube vent )

Early Ford Crossover tube....

1) 5- 3/4" tall from the top of the mounting foot to the top of the tube.
2) Tube is offset to the rear of the center of the foot
3) Mounting foot is towards the pass fender, i.e. the nuts are on the FENDER side of the versicle part of the bracket.
4) Spark plug wire hole is towards the front of the bracket
5) Rubber grommet is black
6) Strengthening ribs are closer to the nuts and are SHORT like the later style, not LONG as shown in the photo
7) Tube/mount are painted the same black as the carb air horn.

Best of all, the block "F" is stamped on the carb side just above the plug wire hole so you know it's a GPW made item.  

Slat Grill (Early) Support is 1/2" different to later standard support

Black gloss enamel Willys also used 3 variations, early which was taller, then as for the GPW's No F Stamping on the upright base.

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.

FRAME (CHASSIS) 

VEP* Very Early Production

Early GPW frames were made by Midland Steel Co. and made to Willys specs. Ford purchased them from Midland direct. Later GPW frames were purchased by Ford from Murray Co.

This applies to the Ford Jeep produced between February 1942 and August 1945

TM-10 1513 & TM-10 1349 Changes to the Chassis Illustrations & Measurements

O/Drab

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.

Firewall mounted fuel filter was eliminated sometime around May-June 1945. This was accomplished sometime between body number 232581 (May ‘45) and body 243776 (June ‘45)*

Firewall mounting holes were dropped about June 1st 1945

GENERATOR

TM-10-1348 Exploded View

Download either the TM-10-1348 Ford List or SNL-G503 which is on the Main Page

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.)

The spring catch on the door went away in Oct. '44. Only GPWs with key lock glove box doors were delivered with a spring attached to the door. All other GPWs through sometime in Oct. '44 used the spring in the assembly process but it was removed prior to final assembly.

The spring catch in the floor of the glove box continued through the end of GPW production. (Tom Wolboldt 2012)

FORD GPW :

Early - Rubber - Green to August 1942. It would appear,  yet to be verified, that there were two sizes of the early Rubber Hood Blocks 1" and 5/8" in height. 

Plain Wood - Not Used on GPW's

Wood with Insert Painted Olive Drab August 1942 to end of production. Various plants had varying starting dates. 

Hood welting rivets: Rivets installed head-up with legs bent under lip of grille. These rivets were S2 finished

Under Hood Lever Grease Gun fitted sometime after Willys depending on which Ford Factory manufactured the jeep. Early (Jan, Feb, March) 1944 is the current hypothesis. Brands fitted were Lincoln and Alemite

WILLYS MB:
Green Rubber: Start of production to early September 1942 Veh. No. 218345. Part No. A-2922 

Wood: Early September 1942 (Veh. No 218346) to June 1943

Wood/With Insert: June 1943 to end of production

Hood welting rivets: Rivets installed head-up with legs bent under lip of grille. These rivets were S2 finished

Under Hood Grease Gun Lever grease gun and bracket were issued by the factory on a Willys BOM page dated 13 NOV 43 and MB-NOM-12 with the BOM dated 3 JAN 44. So Factory MB's could have been fitted from that date onwards. Lever Grease Gun and plunger is Plated, end cap is plated. Lever and attaching end is painted Olive Drab. Nozzle is Plated.

Usually Red primer. However, one MB dated Feb '42 have been found parts with black primer:  Bonnet (hood) headlamp brackets, grill, all air deflectors, floor plate, starter heat shield ( Doug. Ingram 2014)

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  

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 possibility that these were phased out over the production of the Ford made jeeps.

Ford was not directed to change their GPW contract to add "War Department Lubrication Guide No. 501 " to a GPW until May 18, 1944. The change of adding the lube guide no. 501 was to take effect as soon a possible but as the data shows this was about a 7 week period of time. .(Tom.W. Mar 04, 2013)

Late Late war GPWs did not have a lube chart holder under the hood only dimples where it would have been mounted. The lube chart used was the new folding type which was stored in the glove box.(Tom.W. 24Jan2012)

OIL FILTERS

Egg Shell -  Black 

Two types of tops for the Purolator STANDARD MILITARY  FILTER both Marked 25791 

Military Junior filter and the Purolator part number 26638 was  not used on MB or GPW jeeps.

Top plate retaining bolt is Cad plated for both PurOlater and Fram filters

*** PurOlater Type, Unprimed under Black with silver  stencil marks of PD-5106  not PD-51   on top  and INLET in silver    

 "PD-5101" was used for both Dodges and MB's after Ford began to use the Purolator on the GPW. Before Ford began using them they were only marked PD-51...there was no reason to use the "01" or "06". Purolator began using PD-5106 to denote oil filters meant for GPW's since they had a Ford decal. The 5101 denoted the standard filter (two decals). [Michael O'Connell 2014 ]The inverted INLET shown above is a marking mistake

"F" Decals fitted

March / April 1943 on - FRAM or PurOlater Fitted as seen on Richmond built jeeps unpacked from crates in Australia
