How can I check the concentricity of the bearing seat?
With a dial indicator, (measuring) (measurement) platform, guide rail, bearing axial check circle around the next beat is super bad

Coaxiality can be checked with a coaxial meter. Check the main sleeve socket before checking and tighten the bearing cap with the specified torque. The tester is positioned with the front and rear two bearing holes, and the mandrel can slide or rotate along the two locating sleeves. When checking, the mandrel moves along the axial direction, and the measured value of the contacts in different seats is the coaxiality of each seat hole after the two holes of the frying hole. National standard provisions: who can wear alloy compensate concentricity error with the reduction. In both ends of cylinder crankshaft bearing hole common axis as a benchmark, to have a crankshaft bearing hole of the coaxial tolerance must be 0.15mm, the instrument, the main bearing seat hole coaxiality error can also be used to test rod (available lever instead) and to measure the upcoming test feeler rod is inserted into the seat hole, with a feeler gap between the seat hole and the measured value is the test rod coaxial error.
