5.13 Replacing the Engine
Wacker BPU series reversible vibroplates are powered by Robin or
Honda engines in either 5.0, 5.5, or 8 hp models. Replacing the engine
is similar for either type of engine; however, there are subtle
differences. Older plates have a beltguard mounted directly to the
engine. On newer models the beltguard is mounted to a baseplate that
is mounted to the upper mass.
Engine Removal
5.13.1 Remove the tubular frame from the plate.
5.13.2 Remove drive belt, pulley, and clutch from engine drive shaft.
5.13.3 On older models, remove the four bolts securing the beltguard to the
engine.
On newer models, remove the four bolts securing the beltguard to the
baseplate.
5.13.4 Remove engine mounting bolts and using an appropriate hoist or
crane, lift the engine off the upper mass.
