Description

Main Line Boring Machine – Description for Automotive Engine Rebuild

The Main Line Boring Machine is a precision-engineered tool used for reboring and aligning the main bearing bores of engine blocks during rebuilding. It restores factory alignment and roundness of the main bearing housing line, ensuring smooth crankshaft rotation and optimal oil clearance.

Key Applications:

  • Re-machining of worn or distorted main bearing bores
  • Aligning main bores after block decking, welding, or cap replacement
  • Correcting housing alignment in performance or heavy-duty engine builds
  • Suitable for passenger cars, trucks, tractors, and heavy diesel engines

Features:

  • Rigid boring bar with high-precision bearings
  • Adjustable supports for various block sizes
  • Suitable for cast iron and aluminum engine blocks
  • Provides consistent bore diameter and alignment within ±0.01 mm
