Starter engage-switch assembly identified by Isuzu reference 1811001330. Exact-number catalog records name 1-81100133-0 as SWITCH; ENGAGE STARTER and publish Isuzu FVR34 with the 6HK1 engine. Five exact owned photographs show the same cylindrical electromagnetic switch, plunger, return spring, mounting flange and high-current terminals. 1-81100133-0 and 181100-1330 are formatting aliases of the same part. The inherited 6BG1 claim was removed because the strongest exact-number evidence supports FVR34/6HK1; 1811001331 is kept only as a related revision pending supersession evidence. Confirm voltage, flange, plunger travel, terminal layout, starter model and vehicle serial before ordering.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
