Starter Motor for Onan BGD, MCE, NHD, NHE & NHM Emerald RV Generators
Onan Emerald RV generator sets 3.5-6.5kW, 1975 onwards - 12V, counter-clockwise, 16-tooth
A starter motor is the component that cranks the engine over to begin combustion. If it fails to engage, spins without turning the engine, or does not respond at all when the start button is pressed, the engine will not start. This starter motor is built for Onan BGD, BGDL, BGE, BGEL, MCE, NHD, NHDL, NHE, NHEL and NHM engines, as used in the Onan Emerald series RV generator sets from 3.5kW to 6.5kW, engineered as a direct replacement that matches the original unit's fit, mounting and function.
It is a 12V permanent magnet direct drive (PMDD) unit with counter-clockwise (CCW) rotation and a 16-tooth drive pinion, matching the original Onan specification. Onan engines are widely used to power generator sets, so a reliable, correctly-specified starter is important for equipment that needs to start on demand.

Frequently Asked Questions
Will this fit without modification?
Yes, this starter motor is built to match the original Onan unit's rotation and drive pinion, so it installs as a direct swap.
What's included?
One new 12V starter motor, ready to fit.
How do I know my old starter has failed?
Common signs are a single click with no crank, a slow or straining crank, or no response at all when the start button is pressed.
How do I confirm this fits my Onan unit?
Check the engine model code on your generator's data plate against the BGD, BGE, MCE, NHD, NHE and NHM families listed above, then match the Onan 191- series part number stamped on your original starter.
