I think Mark answers the question.

A spacer would either not move the slinger at all or move it closer to the timing cover, not away.  It would also change the position of the pulley, causing problems with belt alignment.

6700 is the Timing Cover Seal. 6310 is the Oil Slinger. Keeps Oil off the Seal to better prevent Leaks. Sometimes the Slinger gets missed when re-assembling Engine. It was missing on mine.I don't see a Spacer listed for Y Block.

  

Drawing for Y-Block Crankshaft Assembly 1955 - 1962 shows oil slinger #6310 and spacer #6700 ... then harmonic balance.  When I pull oil pan and look back at front end of crank assembly it appears oil slinger up against timing cover - would think a spacer would take care of this.  Crank turns OK when I take harmonic balance off and then turn it with bolt/washer.  Some say oil slinger takes place of spacer, but that's not what the drawing shows and others just a spacer.  Anybody have any ideas, or even what the thickness of the spacer is suppose to be ... would like to finish this assembly correctly.  HELP

The spacer may be for the 1954 Ford with the 239 without power steering. Once in a while I see these appear on Ebay.

If You are going by the Shop Manual I believe its an Error. The Picture shows what  looks like a Spacer and Mentions One in the Text but there is no Picture of the Oil Slinger in the Illustration. I think that "Spacer" shown in the Picture was supposed to be the Oil Slinger. The Snout of the Harmonic Balancer holds the Slinger in Place against the Cam Gear. The Camshaft has a Spacer and I think the 2 got mixed up with Crankshaft.

  

I've never seen a spacer on any Y block I've worked on. FE's have them

Does anyone have the spacer that goes in front of the oil slinger on the crankshaft ... or know where to buy one
