Description
This machined billet adapter bolts to the back of the Duromax 713 v-twin engine and allows the factory drive shaft to bolt to it. This part is used with repowering the later model 316, 318 and 420 engines that came with a factory OEM Onan engine. Adapter includes hardware to mount adapter to Duromax engine.
HUB specs are, Bolts to the Duromax engine with 3 supplied bolts, has a 2” diameter recessed pilot, Has (2) 5/16-18 threaded holes 2.750 C-C.
The stock driveshaft uses 4 bolts but that pattern will not fit with the 3 bolt pattern of the Duromax so you will only use 2 of the 4.
