JDpartsman Posted January 16 Share Posted January 16 May be cheaper and easier to find a used distributor in better shape. 1 Quote Link to comment Share on other sites More sharing options...
cedar farm Posted January 16 Share Posted January 16 The weights can be saved and the pins replaced if that's what's worn. It's been awhile but I believe its a #50 double chain connector you need. Drill out the weights to that size. Grind out your old pins and use the chain pins as new weld in replacements. 3 Quote Link to comment Share on other sites More sharing options...

snoshoe Posted January 17 Share Posted January 17 It has to be a compromise. You are left to wonder what total advance is and what springs for advance curve was used. That said it will probably be closer to right than a worn one. Quote Link to comment Share on other sites More sharing options...

DWV Posted January 18 Share Posted January 18 Be interesting to know what the advance rate and total is in the replacement distributors. Most tractor listed as distributor fitting came with 30 or 40 degrees total advance at crank. If fire crater pistons were used most were supposed to be changed to 22 degrees. Since a gasoline 400 was 25 degrees no distributor change parts included with a complete fire crater kit on those. Quote Link to comment Share on other sites More sharing options...

Educate me for a minute what happens if you don't have the 22-degree advance in the distributor will they tractor still run just not as well or does it start to "diesel" where it pre ignites?

You had the same findings as I did . And I laughed when I saw that little sticker. What were we supposed to do send every one back that was not at #1 tdc right out of the box? I had 1 fail out of many sold when the Stiener distributers had cast Iron housings the new Aluminum ones I only have sold 2 or 3 so I don't have a lot of history.

Could run better with more advance depending on fuel octane and engine cooling. IH limited the advance for tractors working hours under load to prevent pre ignition or worse. Removed several pistons with rough tops caused by little pieces flaked off. Worse case after pre ignition is edge of pistons burnt down to top ring. Instructions IH sent with F.C. kits was to set max advance at full throttle even if time feel back below TDC at idle within reason. Quote Link to comment Share on other sites More sharing options...
560Dennis Posted January 18 Share Posted January 18 I’ve made new pins for insertion to the hud flange ,and that put the weights back acceptable operation. Don’t remember but I did it for magneto on C and did this also to the super C distributor. should be able get new springs from bates Corp. I don’t recommend any be scrapped they can be refurbished. 1 Quote Link to comment Share on other sites More sharing options...
