Guest buickkuhn Posted October 17, 2014 Share Posted October 17, 2014 I am a first time babbit bearing looker . This is my baby bought her in 2000 and now the 248ci motor is taken apart for work to be done ,but I am on the hunt for someone to do the babbitting crank and rod bearings . I know I can get the 49 1/2 / 50 rods to have press in bearings or even have my rods notched to accept the press ins . The crank still main bearings done . I am located in oakland county Michigan 48371 and looking for the shop or person that can help in this getting done . I also e mailed Harts machine shop in cicel ohio on a tip from another forum person . If you have had this done and by who also how much $ because I am trying to set a budget up for the project for this winter . Thank you Link to comment Share on other sites More sharing options...
pont35cpe Posted October 17, 2014 Share Posted October 17, 2014 I have a `41 248 super engine I just went thru. I updated the rods to the insert type, they were $40ea exchange, thru Terrill Machine Shop in De Leon, Texas.. The mains in my engine were insert type, not babbitt like the rods, approx. $100 per set, I bought at the same place.. The rods fit perfect without having to be shimmed like the babbitt rods, mains still have to be shimmed for correct clearance.. Also be careful, all the main journals are different diameter.. Also the timing marks on the cam/crankshaft gears are clocked at 3 o`clock with 11 links between the marks, not the normal 6 and 12 0`clock like most engines.. Good luck Tom Link to comment Share on other sites More sharing options...
Buicknutty Posted October 17, 2014 Share Posted October 17, 2014 I did the very same thing on my '41 Roadmaster, which has the 320 engine. I believe that all the '41s have insert mains and babbit rods. Don't know why, as it seems a bit odd, but it must of made sense at the time. I also had the rods modified for inserts by Terrill Machine, and have been very happy with the results. The original babbit was still within spec for wear, but apparently it can start to fail due to fatigue after many miles, years, and dirt being pounded into it. Since I was building my car to a good driver, I wanted good reliable engine. I've done about 4,000 miles in 2 1/2 summers, so far so good! Keep us posted on your progress.

Dynaflash8 Posted October 20, 2014 Share Posted October 20, 2014 Main bearings are semi-finished inserts until mid-1947. That means a machine show has to fit them to the crankshaft I believe. Link to comment Share on other sites More sharing options...

That means a machine show has to fit them to the crankshaft I believe.Ok - I did remove a middle main cap and it had a press in bearing still very soft material .The only markings is a capital " M " .I have found myself going into the garage and telling the buick you will be better ,this is for the better . As if the garage was a hospital ... Link to comment Share on other sites More sharing options...
DonMicheletti Posted October 20, 2014 Share Posted October 20, 2014 If the main bearing journals, smooth and round and the main inserts good, you could reuse them and just remove shims to get proper clearance Link to comment Share on other sites More sharing options...
Guest buickkuhn Posted October 20, 2014 Share Posted October 20, 2014 When I get the motor out of the car I am going to plasti guage some things to check tolerances before tear down . Link to comment Share on other sites More sharing options...
Buicknutty Posted October 21, 2014 Share Posted October 21, 2014 I agree that checking things out before hand is a good idea. I always do, as that will give you a better idea what's going on, and what it needs. To plastiguage everything is a PIA, but I think it's worth it, especially when doing final assembly.Keith Link to comment Share on other sites More sharing options...
Guest buickkuhn Posted October 21, 2014 Share Posted October 21, 2014 To make the car last as long as it has , the factory and past owners did a good job to my 41 buick . Now it is my turn to contribute to making it last . Also so I can get back to driving it more often .So this process of trying to learn all the little tricks and the different shops to use is like a quest the buick and I are on .
