Guest dnoz Posted October 23, 2014 Share Posted October 23, 2014 I have a 1913 Buick, Model 25. Heard an engine knock and appeared to be in the crank case. Removed pan and one of the connecting rod bearings had disintegrated. I need some help.Can anyone provide me for this engine: the spec (dia) of the connecting rod journal; the torque spec for connecting rod caps; and a source for the bearings.Any help would be greatly appreciated.David Nozneskydnoznesky@aol.com1913 Buick Model 25Hobe Sound, FL Link to comment Share on other sites More sharing options...
Owen_Dyneto Posted October 23, 2014 Share Posted October 23, 2014 I can highly recommend "Pauls Rod & Bearing" for babbitt bearing work. In Kansas City, MO. Link to comment Share on other sites More sharing options...
dictator27 Posted October 23, 2014 Share Posted October 23, 2014 Can't help with the con rod journal diameter. There are no torque specs for engines that old. Torque wrenches didn't exist until the mid/late thirties. There are charts available which will give you the maximum stress that can be put on bolts of a specific size and thread count, but keep in mind that you have 100 year old bolts which will not be the same quality of material as modern bolts. The bearings will be poured babbitt, not shell bearings. You will have to find a machine shop which can make, pour, scrape and fit the babbitt material. If you have to do one, do them all. The others may not be far behind this one.Terry Link to comment Share on other sites More sharing options...
37_Roadmaster_C Posted October 23, 2014 Share Posted October 23, 2014 (edited) David,I really can't help much, but I agree with Terry as to having all of the rods done. Also, you might want to post on the Pre-War Buick forum as there are many Buick people there who would be willing to answer your questions. Mark Shaw is the prewar Buick club director and he owns simular cars and would be a great help.EDIT: I see you have posted in prewar Buick and already have one answer Edited October 23, 2014 by 37_Roadmaster_C more info (see edit history) Link to comment Share on other sites More sharing options...
Guest Posted October 24, 2014 Share Posted October 24, 2014 You might try Egge Machine. www.egge.com Link to comment Share on other sites More sharing options...
herm111 Posted October 25, 2014 Share Posted October 25, 2014 (edited) David, find out what you have for bolt size. I am guessing that they are Maybe 3/8's fine.If they are, the torque would be 30 Ft Pounds, and then just pull for the key hole after that.These are 1930 Buick Rods, and mains.We have a set of 1915 Buick rods and mains we are building also right now.Herm Edited October 25, 2014 by herm111 (see edit history) Link to comment Share on other sites More sharing options...
