Briggs & Stratton 706778 Short Block Engine Assembly

The Briggs & Stratton 706778 Short Block is a genuine OEM replacement short block assembly designed for use in Briggs & Stratton small engines. A short block is the foundational lower engine assembly, typically including the cylinder block, crankshaft, camshaft, connecting rod, and piston — everything needed to rebuild or replace a worn or damaged engine core.

Using a genuine Briggs & Stratton short block ensures proper fit, factory tolerances, and reliable performance. This is the preferred solution when an engine has suffered internal damage such as a spun bearing, seized piston, bent crankshaft, or significant cylinder wear, avoiding the cost of a complete engine replacement.

Key Features:

• Genuine Briggs & Stratton OEM short block assembly
• Includes cylinder block, crankshaft, camshaft, connecting rod, and piston assembly
• Engineered to factory specifications for precise fit and long-term durability
• Ideal for engine rebuilds when the top-end components (carburetor, ignition, recoil) are still serviceable
• Direct replacement for worn, seized, or damaged engine cores

Installation typically requires transfer of external components such as the carburetor, air filter assembly, ignition system, recoil starter, and valve cover from the original engine. Always consult the applicable Briggs & Stratton service manual for proper assembly procedures and torque specifications.
