Bearing inserts for 29 Chrysler

A I handed a 29 Series 65 195 cui engine to the rebuilder today and he preferred to not cast new crankshaft bearings but rather turn the areas down to accept regular ("modern") inserts, has anyone any experience with this and may you have recommendations for what might fit? Same goes for the valves, anyone have experience for what might fit straight away or be a close fit for this engine?

thank you

(the car's bodywork was much worse than the engine but is now almost done)

I would also like to do the same thing to my 1931 DBs.

Surely there must be someone out there who did not recast the bearings during an overhaul?

Every auto machine shop used to have a catalog that listed parts by dimensions. No doubt today they have a database.

Measure the crankshaft and see what size bearings you need and look them up. You may need the help of a friendly machine shop or parts store.

Narve-There might be an insert bearing which will fit your block but the simpler approach is to rebabbit your insert shells oversize then install them in the block with bearing caps torqued down and line bore the rebabbited inserts in the block to fit your crankshaft main bearing journal diameter after you polish or grind the crankshaft.

The line boring is the service your local garageman probably can't do but there might be a specialist who has the equipment in your country.

Insert bearings in this period had much thicker walls than modern insert shells.

These engines run very smoothly with a proper rebuild.

Be sure to make a note of the oil relief cuts in the rear main before melting out the old babbit.
