1942 Ford GPW Hanger Queen

[mkoloc]

Michael, thinking that the gent was incorrect on the year. SN for GPW Block is GPW 6015 can't possibly be a 43 engine. Has to be a 1942 block and head. Pretty sure that the block and head are a match or very close looking at the SN for both. 6015 / 6050

The year of the Ford blocks that were installed in jeeps at the factory (not replacement motors) can easily be told by the SERIAL NUMBER on the boss behind the oil filter (same place as you found the MB number on the other block). The "GPW 6015" is the Ford part number, not the motor serial number. Likewise the GPW 6050 number on the head is the GPW part number, not a serial number. Post the serial number on the block and we can help you with dating it.

By the way, the carb you show is probably a 636 series, not used on WWII jeeps. Looks nice and may be a good choice for the 47 CJ. You want a Carter 539S and there are plenty of threads about them if you just search using "carburetor" and limit the search to the FOR SALE forum.

Thanks Chuck, feel kinda sheepish regards SN ...very new to jeeps. Good to go regards the carb as mentioned in my previous post, I have sourced the correct carb as this is probably a CJ carb at best, as was the windshield, voltage regulator and several other items that I've already stripped off and replaced. Used the windshield on my 47 CJ project as I was short that item and will make use of the regulator for the same.

Installed the battery tray and foot starter with new battery cable and wire for am meter ... cleaned up generator and the data plate checked out as correct Autolite model # ...there is also a GPW marked pully under the paint layers.

Mark.....

While some responders may be a bit irritating, if you are thick-skinned.....you can post as many questions along with pics here and you will get plenty of help. Often there are differences of opinion between responders and they lead to some new info being aired-out so that is GOOD thing even if your original thread seems to get hijacked. Bear with us...that is how some info comes to light!

[mkoloc]

Yes, read with great interest a post regards Carbs, authentic parts, rebuilds, pricing etc .. you can learn a lot about folks by reading their comments. I very much appreciate your taking the time to help me Chuck. My forte has been halftracks and 3/4 ton trucks, so Jeeps are a pleasant change and I'm eager to educate myself. Way more Jeep owners than halftrack owners so expect the ratio of opinions/experience to be equal in comparison.

Ok here is a pic of the block SN and the frame SN: What year are we thinking here on the engine?

[m3bobby]

GPW 85853 is on the database as Dec 42 so yours is V close to that. There are also a few other close ones too.

M3B that is great news ..so the engine is 1942 manufactured .. just 5 months difference from my jeeps production date. Feel pretty good about that and fortunate to have met the gent here in town with this sitting in his shed. Hoping he might have some other goodies tucked away in his storage container...although its very much a slow walk due to both age and his wariness ...

Good day in the shop...pulled the fuel tank after siphoning out the tank as I could not get at the drain plug and cleaned out the well. Tank is in really good shape, pulled and reinstalled the drain plug just to get it loosened up and then trimmed the rubber liner that someone had put under the tank and blocked my access to the drain plug.

Installed the missing fuel filter on the firewall, all new and correct fuel lines from tank to carb, installed the missing generator adjuster that was missing and last but not least the missing splash guard. Still have 1 more fuel line bracket to install on the firewall, the one that sits under the air cleaner. Missing foot starter is installed.

Finished my work on the generator and put it back together and installed into the jeep.
Aircleaner cleaned up interior/exterior, element and installed to include the 2 missing butterfly/wingnuts. Wiring run to voltage regulator after new connectors soldered on as the jeep originally had a civilian regulator on it and much smaller wire ends..

Steering wheel pulled as I get ready to swap in the correct Ross box, just waiting for my drag link to arrive. Pulled my broken/frozen speedometer. Original AC but locked up and needle is sitting between 40 and 45 MPH. Someone has painted the needle gold in the GPWs past. Numbers on the wheels look good as does the face. I'm a trained Horologist, watch/clock maker, something I picked up after retiring from the Army. Two and a half year school in York PA, where students are taught to make their own parts. Looking forward to tearing into the speedometer. The two watches on my bench (one torn down) are WWI German Trench Watches with gunmetal finish cases. They are very uniqe pieces because they are both alarm clock watches/chronometers.

Tore into the speedometer. Quite a mess, hairspring trashed, 1st gear frozen, needle shaft missing either a bushing or a jewel but just hanging loose in the housing. Gears are squared away and all spin freely in their housings. Mileage wheels and hardware cleaned and lubricated, needle shaft polished and a new bushing fit into the housing. Going to see if I can salvage the hairspring. Pics of progress.

Hello Mark,

Excellent progress on your nice jeep, just be aware that the speedometer has radioactive paint on it,
and radioactive dust.

Be careful with it, and contain any of it for disposal. I would be certain to wear a respirator as well as gloves.

There are older posts describing the radiation issues with the glow in the dark paint, even if you don't see it glow,
it is still radioactive.


Best Regards,

Ray

Christ Ray, i was not aware of that, you learn loads off this site, you are making good progress Mark.

Ray, appreciate your comments.

I don't wear any special clothing or a respiator. As a Horologist I've read a significant amount of info and data regards radium and tritium dials and hands. The danger is extremely mimimal if at all given the amounts of radium used in the original paint, and tritiums life is 10-12 years at best and has been phased out due to the use other newer and less challenging compounds .

While it is true that the "Radium Girls" who painted dials, hands etc during WWII had a high incidence of cancer, studies show that a significant number of them ingested the active radium as they licked the tips of their brushes to get a finer point (encouraged by management of course) while others painted their teeth, eyelids, fingernails etc to show off the glow in the dark effects too boyfreinds and others. The last radium girl passed away recently at 107 years of age.

I restore a number of WWI and WWII military watches and clocks (aircraft and tank) and always work in a well ventilated area. Years of tracking by NWACC based on the number of watch and clock makers in the association have not shown any significant issues from working on these items. NWACC has printed several articles over the years on this very issue. Of course if you look online there are others who dispute these facts and offer a very different opinion. I guess at age 63, I still enjoy living on the edge .

Hello Mark and Mark,

I am glad you are aware of it, and others as well.
But.....just be careful and thoughtful when handling radioactive materials and dust generated by the paint breaking down
over the years.
I have put a geiger counter on jeep gauges and it clicks all over the place, but the M series are even more radioactive I would imagine .

I have heard of scrap metal being contaminated by the gauges and radium residue, and thus an issue was created.

Some say that the glass on the speedo keeps the radiation shielded, but there is another radiation that is recorded as well, a greater distance back from the speedo.
I am no expert, but just remember reading some important info on an earlier post here on the G503 regarding readings.

Keep up your great works on your jeep !!!


Best Regards,

Ray
