Compatibility / Fitment Guide
Verified basis: Mase generator applications using the Yanmar 4TNE84 engine where the service information lists alternator belt 912357 / Mase 3B7-06902-1 and Yanmar A36.5 belt 119865-42290E.
The Yanmar reference is also used on some 4TNE88 industrial installations, but generator fitment must still be confirmed from the Mase model and serial-specific parts list.
