Bolens H16XT Mower, Lawn and Garden Tractor
Briggs Twin 402437 16hp
A shortblock is no longer available for this. You can use an 18hp Briggs opposed twin, if you do not buy an engine with a big alternator and muffler on it, you will have to use these parts off of your original engine. You will have to use the flywheel drive adapter off of your original engine and possibly your flywheel also. This tractor used a 1" x 3" shaft.
