  • Distributor installation
  • Ford 8n front mount distributor- I recently acquired a 48 Ford 8n that already had the distributor removed and the guy I got it from cant remember which way the rotor was turned during removal. Question I have is installing a new distributor how will I know that I have it correct and not 180 degrees off. He apparently installed the last one wrong and busted the casing . I don't wont to repeat that issue because those distributors don't come cheap. Thanks in advance for any and all replies . You guys are great !

  • Welcome aboard Jessie! It's good to see that you've been doing your homework as well. The Ford tractor front mount distributor is mounted one correct way but you can get it off 180 if you force it. Theersults are as you stated - the base at the cam and weight tang will crack rendering it as junk with no known repair other than to replace the guts with a new base or get a backup unit installed. Bruce offered some installation advice and I'll add that I use a good Mini-Mag flashlight and a telescoping inspection mirror to observe the cam shaft end and match it up with the distributor tang end. Fit by hand into the slot and 'feel' that it is mounted flat on engine face. Hold in place and look to see there are no gaps from mating surfaces. Hand fasten bolts in place and observe flatness again before tightening down. Once satisfied it is mounted correctly, attache plug wires in correct order - 1,2,4,3. The inspection mirror method has always worked for me.

  • As Rusty said..... it's possible to put it back on wrong & break it. Look at the slot on the end of the cam shaft. Whatever angle it happens to be, turn the distributor tang to match it. Make sure you can tell the wide side from the narrow side on both the cam & distributor! (close counts). Place the distributor on the front of the engine, gently push it in place & slowly turn the distributor body until you feel the tang slip into the slot. Rotate the distributor body until the bolt holes line up. Hand tighten the two bolts until the distributor body is flush with the timing gear cover.

  • That front. Ount distributed only goes on one way! Look at the back of dist and you will see that the tang is not centered and is angled on one side, match that with the slot on the end of camshaft if it sits flat against the block with the bolt holes lined up it is correct.
