kgreen Posted November 20, 2016 Share Posted November 20, 2016 What years of starter will work on this engine? I'm looking for compatibility with other years for a spare starter. I understand that if I keep a spare in the trunk the original unit will never fail! Link to comment Share on other sites More sharing options...
Marty Roth Posted November 20, 2016 Share Posted November 20, 2016 Someone once told me that 1937 through 1952 will work, but I'm not certain. Just yesterday an oldtimer mentioned that, while both may have had a 320ci, a Super and Roadmaster in some years had differing internals (2 vs 4 Field Coils?) Hopefully an expert will add some advice here. Link to comment Share on other sites More sharing options...
Daves1940Buick56S Posted November 21, 2016 Share Posted November 21, 2016 Marty: Supers had the 248/263. Maybe you are thinking of the Century? Cheers, Dave Link to comment Share on other sites More sharing options...

My parts book lists the following Grp 2.041 MOTOR, CRANKING Part No 1107908 - 1939 - 60 - 80 - 90 : 1940 - 60 - 70 - 80 - 90 : 1941 - 60 - 70 It seems you are restricted to a starter motor from these years. I believe Marty's old timer is right about the 2 V's 4 field coils. In some instances ( have heard of 1937 ) the starter motors from a 40 Series ( small engine ) will physically fit the larger Series engines but lack the power to turn the motor sufficiently for start up.

Thanks 50JB!. I'm not looking at the two starters, but aside from the part number, I wonder if the 2 vs 4 field coil is a good identifier then I could count the phillips screws on the case. Again, I appreciate your help. Ken Link to comment Share on other sites More sharing options...

I don't have the car in front of me yet so I can't tell you what I have. My goal is to acquire a second starter for rebuild as a spare part for a driver. I can share this number in a week or so when the car is in my garage. Link to comment Share on other sites More sharing options...
DonMicheletti Posted November 22, 2016 Share Posted November 22, 2016 I like your logic. If you have a spare part with you it is guaranteed that the one in service will not fail. Link to comment Share on other sites More sharing options...
37_Roadmaster_C Posted November 22, 2016 Share Posted November 22, 2016 I think 50JETBACK is right. If I remember right, it was quite an issue to get info on my 37 320 starter. The issue was that buick changed the ring gear on the flywheel and that changes the starter mating gear. I think the change was in 39. Others may have more or better info.

Cheers, Dave You are correct, but what he MEANT to tell me was that he used a Roadmaster starter on a Super for the Four vs Two Field Coils, and got much better performance from the starter - sorry for the confusion Link to comment Share on other sites More sharing options...
