B2016A planer, due to the main drive worm box fragmentation and replacement parts. Assembly, often found on the worm box four φ20 mm locating tapered bore axis and the axis of the locating taper hole irregularities deviate from 2 to 4 mm, can not locate the assembly, only the original tapered hole size to expand.
