I have rolled in new bearings in a Spitfire with almost no trouble, I 
don't know why a TR4 should be different.  The only problem I had was 
the top half of the rear main bearing.  I left the old one in with no 
apparent trouble, If I'd been clever, I'd have made a pin to slip in 
the oil hole in the crank to push the old shell out and the new one 
in.  The rest went out and in by hand.

Make sure the pin has a head larger than the oil hole...you wouldn't 
want to lose it in there.
