    And as Plymouthy mentioned on another thread on this subject ; When you punture the old plug , do it near the center and not on the outer edge to prevent damage to the engine block . There is an inner ledge when the plug fits as Reg shows in his photo in message number 11 .

    I have read that on the older radiators that were designed to run with low or no pressure , that if you run 8 pounds of pressure in them , the top tank will ' oil can ' with the hot and cold cycles . This will cause a split seam over time . Any truth in it ? I don't know for sure .

    You will find that when you change the face plates that you will be changing the glass covering too . A good way to bend the little tabs that hold the face plates on is to use a knife blade . When you are ready to bend the little tabs back in place you can just push them in place using the edge of your work bench .

    And most of us do our own alterations as we like .

    1949 , 1950 Auto-Lite starter motors start with letter M , such as : MCH-6103 , MCH 6106

    The IAP-4101-1 distributor was issued to the 1948 - 1949 trucks B-1-B with the T142 engine and B-1-C with the T144 engine . It would have an oil cup and not a grease cup .

    Take a look at ebay item 201317934816 and you will see a distributor with a grease cup in the side of the body . the newer distributors have an oil cup there . You can see the newer style if you do a search on ebay . There is also another spot to oil , and that is under the rotor , lift the rotor and you will see some felt to oil . One weaker spring on your mechanical advance is normal .

    Keep in mind that the pictures in both of those catalogs are generic . They don't show a true photo for each and every item .

    I spent half a day going from shop to shop looking for a place to make up that rubber line . I ended up buying one on ebay .

    You can also just hook it up to a 6 volt car battery .

    When honing you can use brake fluid as a lubricant . You want to end up with a bore that is super smooth . Many years ago when I was doing them , i did the final polishing with crocus cloth . Think of the finest sandpaper and then go to crocus cloth that feels even smoother .

    One of the members once said that you can use a narrow V belt in a wide pulley . If this is possible then you can do a test for vibration without modifying your new damper pulley . Just a test - not permanent .

    I ran my engine with oversized pistons for two years and it was then sleeved back to standard size . No vibration ether way .

    PT 81 , When I was a kid in a family with 5 children and we were noisy , my dad would say " put a damper on it ! " Perhaps that is what they did at mopar when a new engine was developed that was noisy with vibration . My 1939 Dodge car engine doesn't have a damper and doesn't have a vibration . I can see by your photos that you took great care to make your truck nice and it is understandable that you don't want that vibration.

    Here is some general information on dampers printed in Motors Auto Engines & Electrical Systems ; Printed in 1976

    PT81 1939 Plymouth truck , Are you sure that it is a 218 ? Could it be a 218 from a later model car that came with a damper ? Perhaps the damper was removed and the old stuff from the original engine was placed on the front because the damper wouldn't fit . For example : a 1939 Dodge truck model TC came with a 201 engine . Have you researched the number on the side of the engine to verify what it was made for ? If the engine came originally with a damper , for sure you would want to put a damper on it again . If you want to post your engine number someone can look it up .

    My thinking wasn't intended as a complete solution to the problem , only to help find the cause of the vibration . You could then eliminate the lack of a damper as a cause .

    Is there enough room to install the belt on the damper pulley , then bolt the damper onto the engine , then put the belt on the upper parts , then test drive ?
  20. Jerry Roberts
    Are you aware that some of the mopar harmonic balancers were made with a flat spot that was used as a space for belt installation ?

    Some of the manifold bolts , water pump bolts and cylinder head bolts go into the water jacket .

    Also many of the streets INSIDE of cities were not paved . I remember lots of pot holes .

    " ... assuming this is warpage is NOT something that would be visible from the outside correct? " To see if the head or block is warped you would place a straight edge on the surface . So yes , the head would have to be off the engine . You might also look for bubbles when you look into the top of your radiator with the engine running .
  24. Jerry Roberts
    Did you ad a thin spacer around the front bearing retainer ? In Tom Langdons kit there is a thin sheet metal spacer that you would heat shrink in place to fill the gap and prevent vibration for the truck installation .

    The magic name is Auto-Lite for the rotor and the part number is 1016B . This is for the WC 1946 Dodge truck with distributor model number IGS4203A-1 . I find my NOS Auto-Lite parts on ebay .
