I have a - 1912 car. Two of the
main bearing caps and upper halves
of bearings broke without any ap-
parent cause whatever. I have had
the crankshaft set up on a lathe, but
it seems to be in Al condition. The
other bearing is all right. Can you
tell me what caused these bearings
and caps to crack? Kindly obEge.-

caps to cause them to break.
If the shaft was properly aligned
and the bearings properly fitted there
is no reason why they should break
in the manner mentioned.

Answer-YOu state that the petcocks are

the clearance is sufficient to give the valves
