Guest erector Posted June 10, 2010 Share Posted June 10, 2010 Hi again. As usual I need more help. My distributor on my 40 buick doesn't seem to be advancing properly, actually at all. Anyone know where I can get the parts to overhaul my distributor? Maybe even some advice! It has plenty of vacuum. It is old though.Thanks!

Guest erector Posted June 29, 2010 Share Posted June 29, 2010 Thanks John. Apparently there must not be any way to do it ourselves. May try anyway. Like a challenge!Ercell Link to comment Share on other sites More sharing options...
jeff Posted June 29, 2010 Share Posted June 29, 2010 Also check your mechanical advance. You should be able to rotate the breaker plate and feel it return with the force of the springs. If not, remove the distributor, (be sure to mark both the position of the rotor and the body of the distributor to the engine block) then remove the rotor, points, condensor and the breaker plate itself. Now you will be able to see the weights. In my car, the weights were dirty, rusty, etc. I gave them a nice bath in kerosene, a little light lube, and reassembled.Jeff Link to comment Share on other sites More sharing options...
bubba Posted June 29, 2010 Share Posted June 29, 2010 What is the symptom that you are getting? My 40 Buick has a vibration around 30mph and also when the car is sitting still and I rev the engine. Link to comment Share on other sites More sharing options...
Guest MNRoadMaster Posted July 25, 2010 Share Posted July 25, 2010 I saw this and it's a situation I have just dealt with. I took my cap off and cleaned in there as best I could where the plate rotates. I noticed a ball bearing out of place on the side and corrected it. Use low temp cold weather lithium grease on it. See if it moves by hand, Measure what it's getting for vacuum to work with - I had a good reading of 20. Put a vacuum checker on the distributer port and see if it moves correctly with 15 as a measurement - this is what mine worked with -and if not repair / replace the unit.I hope this helps - it's just what worked for me....Don Link to comment Share on other sites More sharing options...
Patrick W. Brooks Posted August 2, 2010 Share Posted August 2, 2010 Good Morning: Have a NOS distributor for your 1940. Cost is $150.00 which includes shipping with the USA. Let me know at brooker50158@hotmail.com I have two 1940 models myself and put NOS in each and it makes a great difference. Thanks, Patrick W.
