Kwik-Way LBM Line Boring Tooling

Key Features

• Engine Block Alignment & Bearing-Bore Re-boring Capability — The LBM is intended for line boring of crankshaft main bearings or cam-shaft bearing tunnels — useful when blocks are worn, out-of-alignment or being converted to insert bearings.
• Portable / Fixture-Based Design — Flexible for Multiple Block Types — Unlike a fixed line-boring machine, the LBM’s rails, supports, and bar-clamp system allow adapting to a wide variety of block shapes and sizes (depending on length and support) — good for mixed-use shops or rebuilders working on different engines.
• Includes Boring Bar, Supports, Bearings, Feed/Drive Mechanism & Tooling Kit (as Sold) — A complete set typically includes the rail/base supports, bored bar with cross-drilled holes for cutter bits, bridge supports, bar bearings, feed mechanism (with multi-speed feed), and a tooling kit — everything needed to perform a main-bore line-bore job (assuming parts are present).
• Well-Suited for Older Engines, Babbitt-Bore Engines, or Insert-Bearing Conversions — Many users value the LBM for rebuilds of older cast-in-babbitt engines or for blocks being updated to modern insert bearings — where full-size line-boring machines may not be economically justified.
• Lower-Cost Alternative to Full Line-Boring Machines — As a used tooling set, the LBM represents a budget-conscious option: less expensive and more “hands-on / shop-flexible” than a dedicated line-boring machine — ideal for small shops, hobby-builders, or low-volume rebuild work.
