  • Ignition System Parts Advice Needed
  • Hello All,
    I just purchased my first 8N. It is a 1949 model with the front distributor. I want to replace the points, condenser, coil, cap, rotor button and plug wires. I see that spare parts for these tractors are plentiful which is good. My problem is I want to buy quality parts and I have no idea what or where to buy. I definitely don't want cheaply made components that are junk out of the box. Any advice on brand names, part numbers, and where to buy would be greatly appreciated. Thanks in advance.

  • Welcome aboard the NTC! First order up is to get copies of the essential manuals for your 8N. Next, be aware these were originally 6-volt/positive ground systems. Many have been switched over to 12 volt jobs. 6-volt systems use a 6V GRP-1 battery, a generator, and a voltage regulator. 12-volts have a 12-volt battery, NEG GRN preferable, with an alternator and NO VOLTAGE REGULATOR. We have a ton of valuable info in our HOW-TO's forum. Go to ELECTRICAL to start with and download a copy of 'WIRING PICTOGRAMS by JMOR'. He has documented every possible CORRECT way to wire these old N's whether 6-volt or 12-volt. This along with Bruce(VA)'s '75 tips For N-Owners' are just as important as the original manuals. Many of us shop at www.just8ns.com and/or www.dennis-carpenter.com so try them for quality parts.

  • I have all the manuals but the one in the upper left corner. I can't read what it is-eyes need overhaul. What is it and where can it be purchased? Thanks.

  • Get your parts at Just8N's.

    When you get the distributor off, make sure you check for bushing wear.

    Got the manuals? See tip # 39.

    And regarding points, see tips 66, 67 & 68.

  • By the way, take the distributor off of the engine; the tang is offset so there is no way to put it back on wrong. I read once where someone changed the points on the tractor and that is just making it way too difficult. You can check the timing when you have the distributor off; you use a straight edge to do this. I saw where someone made a tool to make it easy peasy. I need to put new bushings in my distributor; you can check that when you have the distributor off. You might want to check the distributor cap as well and you may as well replace the rotor button if it looks in doubt. By the way, one aspect over look on these 8Ns is that you don't want to run resistor wires or plugs; you can get solid copper wires and that is what should be on these tractors. The noise issue is gone now that television is digital so no need to run resistor wires and plugs on these tractors; solid copper will give you a hotter spark.

  • Look at NAPA auto parts. I think they still carry the blue streak. I purchased cheap points and condenser for my '49 8N and I was replacing them every year. Since going with the better quality points and condenser it has been four years since I have had to touch the distributor. Mine is still original 6 volt system and it starts with just a few turn over of the engine.
