1954 Ferguson TEA20 # 14 Measuring the new liners in the block (Step by Step Guide)

In this Ferguson TEA20 engine rebuild video, Lance demonstrates the critical step of measuring cylinder liner height (protrusion) to ensure a perfect head gasket seal. Using a dial indicator bridge tool, we explore how to check if your Standard Motor Company engine liners are sitting within the factory specification of .002" to .008" above the block deck. Whether you are using Sparex replacement parts or original components, learning how to correctly shim your wet liners is essential to prevent coolant leaks and engine failure. Part 14 of our Ferguson TEA20 overhaul focuses on the precision task of setting liner height. Lance begins by showing how to create a DIY clamping setup using transmission cover bolts and washers to mimic the downward pressure of a cylinder head. This "dry run" is vital before applying final sealants, as it allows you to determine exactly which aluminum shims are needed to bring the liners into spec. Throughout the video, we walk through the process of zeroing a dial gauge on the block surface and taking measurements at four points around each liner to find the average protrusion. Lance explains the difference between the original paper gaskets and the modern Sparex aluminum gaskets (Part S.42488), demonstrating how even a single shim can make the difference between a liner being "below deck" or perfectly positioned. We wrap up by preparing for final assembly using Loctite 515 to seal the bottom of the liners once the heights are verified.
