1913 Buick Model 25 Rod Bearing

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.

I can highly recommend "Pauls Rod & Bearing" for babbitt bearing work. In Kansas City, MO.

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.

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

You might try Egge Machine. www.egge.com

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.
