  • 1933 v8 Crankshaft/Rod Bearing "Oversized"

    I noticed when looking to purchase replacement bearing that they list standard size plus additional oversized sized. Why are there oversized sizes, Is this to do with the original block size variations?

    If the crank journals have been ground / resurfaced an oversize bearing is needed. You will need to take measurements to determine what is needed.

      Great to know. So the outside of the bearings are all the same diameter, it is the inside "The surface that wears" that changes with oversized bearings. So, I guess you would measure, with a caliper, the diameter of the crank shaft rod where the rods are attached to see the bearing size needed.

        Correct it's the inside diameter that is over sized to compensate for any machining

          New Waterpump Roller Bearing Issues...
          by Kevin in NJ
          I was measuring the rollers of the bearings for least wear. It appears the rollers for the waterpump front bearing should be .25" in diameter.

          Some original spiral type bearings had about .002" wear.
          A couple of the solid type bearings were about .001"+ wear.
          A couple were right on .250".
          The older stock new bearins were right on.250"

          Early V8 throw out bearing question
          by Great Lakes Greg
          To use a V8 flywheel and pressure plate, do I need to use the Model A throw out bearing (seen through the bell housing access hole), or the shorter part pictured on the bench?

          Rod Bearing Side Play
          by dmaxweb
          I know it's not the most accurate measurment but I just checked with a feeler gauge.
          #1 .014
          #2 .014
          #3 .026
          #4 .010

          This seems way out of spec (especially #3). I have not yet removed the caps.

          Oil grooves
          by Hazelhoff
          I have tried this on ‘another Model A forum’ ... but ... you know !
          I’ll try it on this very serious forum for a change. For a couple of months now I find myself being annoyed by the presence of the famous spiral grooves in Model A Babbitt bearings. I can understand someone adding some sort of oil groove in the upper half of a crankshaft bearing - helping distribute the oil - but never...

          Wrote the below and just went out to the garage to look again - I was confused on the below - so never mind for now, need to get the bearing off to see what I have - something to do tomorrow.


          Bought a used armature to repair a bearing/bushing generator with a bad shaft under the bearing....

          Some help. What is the specification for the height of the fingers of the pressure on a F100 1973. How do I adjust them. The pressure is the larger one. Have already taken it for engineering but the height still ain't correct. It seems like the release bearing is vibrating....
