The first Morgan Plus 4s use the same 2.1-liter OHV inline-four found in Triumph TR2-4 sports cars. This engine utilizes a (very heavy) cast-iron block with a 3-bearing crankshaft and press-in cylinder liners. The liner puller being used is a simple homemade piece that I’ve adapted to a slew of different engines over the years. The preferred tool for head stud removal is a standard pipe wrench. Since the 60+ year old head studs will be upgraded – it does not matter if we up the shank. Lots of penetrating oil applied over the course of a few days, as well as a little heat may be required to remove the stubborn ones.
Why you should always pull your liners during a rebuild.
The bare block. Off to be hot tanked, pressure tested, and line honed.
