Str8-8-Dave Posted December 19, 2021 Share Posted December 19, 2021 I'm looking for someone who has a burned out or broken heat riser from a 1931 or 1932 Buick 60 series that I can harvest component linkage parts from. Specifically, I need the cam link and throttle shaft assembly, the large screw and tension spring, the bearing ball that hides under the brass detent plate and the cam and free link from the warmup throttle lever at the other end of the throttle shaft. If you have a burned out or broken heat riser look first at the casting number, the ideal candidate is casting number 146-106. That is, however, not the only casting used on 31/31 60 series cars that have these parts. I can help with other information to verify linkage parts fit. If your riser has the parts shown in the pictures and are willing to sell them, please message me or e-mail dkrugler@msn.com Thanks. This is a 1931 60 series riser casting #146-106. If you have one of these with this casting number that is burned out or broken but still has the linkage parts shown in the next pictures and are willing to sell either the entire assembly or just the linkage parts please contact me via PM or e-mail. The linkage parts in casting 146-106 will definitely work but if you have a different number casting that looks like this one there are other ways to check compatibility, please contact me for details. The next 2 pictures show the cam link and throttle shaft assembly both removed from the heat riser and assembled. I also need the big screw, the spring under the screw and the bearing ball under the brass detent plate identified by the arrows. The next 2 pictures show the warmup throttle cam and free link that are operated by the throttle lever on the steering wheel hub. Link to comment Share on other sites More sharing options...
