    D30 distributor parts list

    When you supplied the Autolite number you can see how quickly someone responded with the various Autolite internal parts. These are the Autolite part numbers that you would look for at swap meets and they can be cross referenced into other manufacturers specific part numbers. This is why i collect the various automobile parts suppliers old catalogs just for cross reference issues. You usually do not find the MoPAr numbers on parts but generally the after market parts suppliers. Rich Hartung Desoto1939@aol.com

    Fuel Pump recommendations, are you using a Carter P4259?

    do you have a dual action fp on the new engine? My FP on my 39 Desoto is a single action FP. If a dual action pump it would have a vacuum line to attach the hose to run the vacuum wiper motor. My 39 Desoto has electric wiper so no dual action fp. Just another thought. You might have a leak if you have a dual action pump and therefore lees fuel pressure. Most pumps pull between 3-5 lbs of pressure. just putting out some thoughts on your issue. Also can you explain the routing of the fuel lines that you showed in the pictures. Rich Hartung

    D30 distributor parts list

    The moe important number is to look at the Autolite number that is attached to the body of the distributor. It will have three letter then some numbers. This is important becasue it will then tell us what offical dizzy you have and then we can tell the correct cap, rotor, points and condensor that you need for your car and also the correct vacuum advance unit. I have an Autolite catalog that lists the various information and parts so that is how I can get the information. When going to a vendor such as Andy Berbaum they will always ask for the Autolite Dizzy number so they can get you the correct parts. When searching for parts most times you will not find the mopar numbers on boxes or parts but you will find the aftermarket suppliers that supplied the parts to the car manufacturers. Autolite was a major player in electrical components for alot of car companies. Rich HArtung cell 484-431-8157 Desoto1939@aol.com

    Fuel Pump recommendations, are you using a Carter P4259?

    I can see what you are doing but the straight line from the tank goes into a metal filter then the electric FP. The upper line connects prior to the inline fuel filter then looks to run thru anohter filter and then connects back into the fuel supply line. So in real time the mechanical pump is really pulling gas thru the electric pump even when it is turned off and the upper line is pulling fuel from the gas tank via the mechanical FP at the same time. So with so many connections is there any possibilty of a air leak, but if there is a n air leak I would think that you would have a fuel leak issue also. You stated that this issue startd after the engine rebuild can you verify that the engine build polished the crankshaft and then might have taken to much metal off the fp lobe. This is just a thought but that seems to me to be the issue. So if the car ran fine with proper FP volume prior to the rebuild then I would think that there is an issue with the FP lobe. I am not a mechanic but that is where I would be looking. Also let us know what your results are after the AC588 FP rebuild and then installed on the car. Rich HArtung Desoto1939@aol.com

    Electric fuel pump

    which electric FP did you install? It should be pushing at a rate of 3-5 punds and this should be adequate to keep the car running at idle and also when running down the road at normal highway speeds. If it is not running smooth at idle then i think you have another issue with either the fuel line or carburation. Have you chnaged the rubber line going to the old mechanicl fp do you have a filter on the fule line and is is possibly clogged. I would install a plastic see thru filter and runt he car in you driveway to see if you are getting any sediment inthe filter. This is an indication that the line has crap in it or the fule tank needs to be cleaned. I have a AC588 FP on my 39 desoto and I have good idle and highway speeds and have the airtext electric pump as a backup. Rich Hartung desoto1939@aol.com

    WC Rear axle removal

    the tool that was shown is not an axle puller it is drum puller to puller off the brake drum from the rear tappered axle. To pull the axle you need to remove the brakes and disconnect the brake lines and then remove the backing plate. Then you thread on to th end of the axle a slide hammer axle puller. There were specific miller axle pullers that were factory dealer tools. I have one of the original axle pullers that came out of a mopar dealership. I have attached a copy from the miller tool catalog that shows the factory axle puller. This is what I have, I have the two upper pictures not the bottom picture Rich Hartung Desoto1939@aol.com Miller factory rear Axle pullers.docx
  7. But on a 39 Desoto there is right hand treaded botls on both sides so there is no left or right sided drums and my car is correct with the correct drums and bolts for the lugs. Rich Hartung

    spark plugs

    is there a metal cooper gasket under the plug and seating on the head? If the cooper gasket is missing or possible cracked this might cause the issue. Just a thought. Rich HArtung desoto1939@aol.com

    P15 dash headlight switch 910507 vs 990547

    the top switch is just like the same unit that I have in my 1939 Desoto and yes the round long metal holder at the rear right corner is a fuse holder built into the switch. rich hartung desoto1939@aol.com

    Where to buy a Desoto s11 starter

    Ok the correct stater motor for the 1946-48 Desoto is an Autolite MAw-4025 and according to my Autolite Stater controls printout the correct Selinoid Switch is an Autiolite SS-4707 not the 4705 this was used in 1942 on fluid drive. The SS-4707 was used from 1946-thru 1950 and also used on starter MCH-6102 and MAW 4055. I have the autolite document that shows the details and the settings for adjustements.

  11. You might be correct but why do the mechanics still use the air gun to over tighten the lug nuts on our modern cars? This is because they are lazy and it would require them to use the proper tool or color coded attachment on their air guns to set the proper torque. When you go to Costco for tires the mechanic uses the gun to remove the lug nuts or bolts but their policy is to use a torque wrench set with the proper torque to hand tighten the nuts and then when done the supervisor then rechecks each wheel before they deliver the car back to you. can you tell me if and when you have ever seen this done at any other shop. They always over tighten the nuts and then you have to go back to have them loosened and then hand tighten properly. So time is money in the auto repair business so most mechanics will not taken the time to look at the L or r on the stud or bolt. My point is that on a truck as you state they have been trained for Left threaded bolts but not on the cars becasue we have not used them in 50+ years, so take the time to tell the mechanic and tell them about your car it only takes a minute and if it is any good quality shop they will welcome the information. Also suggest that you stand by the garage door when they are removing the wheel and tell them again about L/R wheel lugs nuts/bolts. I am not rying to argue the point of L/R being used today but it is still your responsibility as the owner of the car to let them know about the difference becsue this is not standard on our modern cars. Rich HArtung Desoto1939@aol.com
  12. No matter how much you paint the flange of the hub Red, orange and any other color it willnot mean anything to one of the modern mechanics of todays training. They have not been taught and will not be taught that there are left hand lug bolts and or nuts on cars. This is not the normal and we can not expect them to know this information. Even if you had a flashing neon sign infront of them prior to taking off the hub cap they still will set their air gun up for right hand threads. it is your responsibility to remind the mechanic 20 times that the left side has left had threads both front and rear becasue only you know the specific about your car. They are trained to work on modern cars and not antiques that are 50+ years old. This is old technology and they have not been exposed to it. Just my 25 cents worthof input.

    53 Fuel Tank Fittings

    when I was Ebay the other day i saw a listing for the crush ferrel that you are talking about and i think Mike W is the person that is selling these for the gas lines. go an find one of his listing undr vintagexxxx and then send him a message. Could you have take the tank to a good gas tank repair and have then soder in a fitting that has a flared end and then make a short piece so that you can use a flared fitting which is more accessable at any good parts house. So cut you line put in a double flare fitting and then add the new section with a double flair witht he appropriate flared nut and you have solved the entire issue. Rich Hartung desoto1939@aol.com
  14. it does not matter if the lugs or bolts are stamped left or right. Most of the mechanics that we have are at best 20 years and they have never been taught that at one point intime there were left and right hand threaded studs or lug bolts so there is no reason for them to look at the stud or nut for the left indicator. These cars are not what they grew up with just like 6 volt positive ground. everything now is 12 volt neg graound. So As the owner it is your job to reminder them of the key point about your car and NOT ASSUME,AXX, that they the odd ball issues with your car. Rich HArtung desoto1939@aol.com
