Wide flanges of thrust-bearing inserts distinguish them from single-purpose radial bearings. Crankshaft thrust-bearing inserts locate in the center main-bearing web. Sometimes bearing-box labels don't tell the truth. Check the bearings to confirm their size. They will be standard (STD) like this one, or so many thousandths undersized: -010, -020, etc. Using Plastigage to check bearing clearance. Lay a strip of Plastigage the full length of the bearing journal (arrow), then install bearing and cap with bolts torqued to specification. Make sure journal is free from oil, and the other bearing caps are torqued first. After final torquing, carefully remove cap and bearing and check width of squeezed Plastigage-it corresponds to the bearing clearance. This Plastigage stuck to the bearing. Sometimes it stays on the bearing journal. Pointed pin in rear main-bearing-cap seal groove prevents rope seal from rotatingdon't remove it if you're usins a rope seal.
