Guest RonB Posted June 29, 2013 Share Posted June 29, 2013 Hi Folks, I am working on a customers 1913 Vulcan and the ring gear on the flywheel is damaged after 100 years of use. . The pinion will engage if it pushed onto the flywheel teeth. Should there be a lead on the teeth to help the pinion engage on the first notch of ther starter? .At present the pinion only engages sometimes ,the cause of the teeth missing the 1st half inch on their profile....I cannot justify pulling the flyheel off again and maching the remaining teeth off and making a ring to suit because of the expense involved. Any ideas most welcome. Link to comment Share on other sites More sharing options...
Curti Posted June 30, 2013 Share Posted June 30, 2013 Contact Al Suehring, he is a ring gear specialist.[TABLE=width: 1045]<tbody>[TR][TD]Al Suehring[/TD][TD]100589 Krogwold Road Amherst Junction WI 54407[/TD][TD]715-677-3809[/TD][TD][/TD][TD]flywheels[/TD][TD]al@suehring.com[/TD][/TR]</tbody><colgroup><col><col><col><col><col><col></colgroup>[/TABLE] Link to comment Share on other sites More sharing options...
Guest RonB Posted August 29, 2013 Share Posted August 29, 2013 Ok,so far i haqve machined a lead onto the pinion to enable it to engage properly. The next problem is the resistor( "E" in the picture) which has failed due to extreme old age . What I need to know is,what is the value of this resistor or does anyone know anyone who can help me calculate the resistance required ?? Cheers! :-) Link to comment Share on other sites More sharing options...
nickelroadster Posted August 29, 2013 Share Posted August 29, 2013 I suggest that you contact Jason at Advanced Electrical Rebuilders. He is on the site quite a bit and has just answered a query about a Delco generator in Wanted section. Link to comment Share on other sites More sharing options...
oldford Posted August 29, 2013 Share Posted August 29, 2013 My guess is that the resistor is simply used as a current limiter, since the armature is a dead short until it starts to spin. I would try a 4 ohm ballast resistor that was used in the 60's Chrysler product. They are available and cheap...Frank Link to comment Share on other sites More sharing options...
Guest RonB Posted August 29, 2013 Share Posted August 29, 2013 Hi Frank, I am sure a ballast resistor wouldnt work because this takes the full battery current load and is designed to slow the amarture down so it will engage correctly. The burnt out resistor is around 6" long and 1" wide and looks like some sort of resistance metal. I'll post some pics later today. Link to comment Share on other sites More sharing options...
Guest richentee Posted August 30, 2013 Share Posted August 30, 2013 Model Ters have been known to use a T bendix spring as a current limiter on their starters when upgrading their electrics from 6 to 12 volts. In lieu of the real thing, this might be a working fix. Link to comment Share on other sites More sharing options...
Guest RonB Posted August 31, 2013 Share Posted August 31, 2013 The resistor appears to be Nichrome alloy strap, finding a vendor willing to sell me a short peice is the problem now, I don't need 25 tons of it Link to comment Share on other sites More sharing options...
unimogjohn Posted August 31, 2013 Share Posted August 31, 2013 This might be an option. It is a wire, but you could soder or crimp the ends to make a bundle. The vendor says he has other sizes available. Worth an email.
